Short answer: AiSDR is the AI SDR agent a startup should start with in 2026. Solo is $250 a month, month to month, for 200 researched contacts, with email, LinkedIn, and warmup included. Instantly is the lower bill if you already send cold email: the Starter bundle is $94 a month, and the agent spends 5 credits per lead. A founder who still approves every email should use Apollo Basic at $49 per user per month on annual billing. Leave 11x until a $3,750 monthly plan, billed annually, is a small line.

A startup should buy the agent it can cancel after a quiet month, and AiSDR Solo is that product. The entry tier is self-serve, with the database, mailboxes, and LinkedIn included, and nothing on that tier locks you into a quarter.
Signing an annual worker before the offer lands is the expensive mistake, because a quiet month still bills the whole term. Sequencers, credit meters, and quote-only BDRs solve different problems, so the table sorts them by the contract you can leave.
Toolradar data: of the 37 AI for sales tools we track, 0 are free and 11 are freemium (30% with a free or freemium plan), while 25 are paid only (68%).
Methodology: these 10 were ranked for a founder or first seller against the 37 tools in the AI for sales category. Prices were checked on vendor pages in September 2026.
Enterprise suites sit in the AI SDR tools guide, and this page is the startup cut of that market. The filter is a self-serve price, no seat minimum, and a contract you can leave after a quiet month.

Best for: A founder who wants an AI SDR this month and a cancel path that is not an annual clause.
- Pro: Solo covers 200 AI-researched contacts a month, one domain, three mailboxes, one LinkedIn account, and HubSpot sync. A HubSpot founder does not need another tool for that stack. Ami for GTM ideas is included, and yearly Solo is $2,400, which is worth paying only if you already plan to stay.
- Pro: Warmup, mailbox creation, and three bounce checks before send are in the plan, so day one does not require a second deliverability tool. Setup is self-serve, which means a founder can start without a sales call or an implementation project.
- Pro: Explore is $900 a month for 800 contacts, two domains, six mailboxes, and five LinkedIn accounts. The quarterly contract is not one to sign in month one. A managed campaign on that tier is $149 extra if you want them to run it, and the AiSDR profile has the product detail.
- Con: There is no free trial, and a cold prospect is quoted at a 1 to 3 percent meeting rate. Treat the contact allowance as a pilot, not a quarter of pipeline, or you will judge the tool on a sample that is too small.
- Con: Scale is $2,500 a month, or $24,000 on the annual price, and that is the first tier with native Salesforce sync. A HubSpot startup should not buy it, and a Salesforce startup will not get that sync on Solo.
While the AI-powered automation and lead generation features are robust, these prices are a significant investment for many businesses.

Best for: Teams that already warm inboxes and want an agent on top, with a human approving the first leads.
- Pro: The AI Sales Agent finds leads, writes a multi-step email sequence, and can run on autopilot. That helps only after you already trust the copy. It costs 5 credits per lead, and 1,000 credits are included to try it, so the test is real but not a forever-free plan.
- Pro: Outreach Growth is $47 a month for unlimited accounts and warmup, 1,000 uploaded contacts, and 5,000 emails. That line is the sending layer under the agent. Growth credits are another $47 a month for 1,500 to 2,000 credits, and you need that second line for the agent to work.
- Pro: At the 1,500-credit floor, five credits a lead buys 300 leads if the pool is spent on nothing else. That pool is the real monthly ceiling on leads. Hypergrowth outreach is $97 a month and raises the cap to 125,000 emails. Instantly alternatives is the page if this meter is the wrong shape.
- Con: The default daily cap is 10, shared by emails sent and leads enriched. Sending and enrichment compete for the same small daily budget. Autopilot stops when that cap or the credit balance hits zero, and the day does not continue on its own.
- Con: Yearly Starter is $85 a month against $94 month to month, and that gap is not worth an annual lock yet. Credits and outreach are separate products, so the outreach price alone understates what the agent will cost.
Instantly's pricing is quite competitive, especially at the lower tiers.

Best for: A small team that wants to test an agent for two weeks before it pays for LinkedIn automation.
- Pro: The Email plan is $69 a month, or $55 a month on yearly billing, which is labeled 20 percent off. Unlimited users, lemAgent, and 50,000 emails a month are included, so the seat count is not what pushes you off this plan.
- Pro: The trial is 14 days with no card and includes multichannel features, enrichment, and buying signals. You can test LinkedIn before you pay to add it.
- Pro: Multichannel is $109 a month, or $87 on yearly billing, with five senders per user plus LinkedIn, a dialer, and SMS. WhatsApp stays an add-on, so price it separately, and compare the mix with Instantly on Instantly vs lemlist.
- Con: LinkedIn automation is not on the Email plan, so a founder who needs that channel in week one is already shopping Multichannel. The Email price was the wrong quote for that buyer, and it looks cheap only until the first LinkedIn step.
- Con: Lead data is a separate subscription, and credits charge only for successful finds, so a miss does not spend the balance. Credits roll over while you stay subscribed, which means the engagement seat is not the data bill.
Lemlist's pricing is on the higher side compared to some market alternatives, with the Email Pro tier starting at $69/user/month.
Watch out

Best for: Founders who want verified contacts and sequences, and do not want an autopilot writing the first touch.
- Pro: As of August 2026, the free tier includes 900 credits a year and two sequences, which is a sample rather than a month of outbound. Basic includes 30,000 credits a year and unlimited sequences at the annual seat in the table, which is where sequence limits stop mattering.
- Pro: Professional is $79 per user per month on annual billing, with 48,000 credits a year, a US dialer, five mailboxes, and AI research. That plan lists 240 million people and 30 million companies, which helps only when your buyers actually sit in that database.
- Pro: Paid plans are self-serve, and the free tier is how you try prospecting before a card, so you do not need a demo to start. The startup CRM guide is the system of record to pair with it, because the pipeline should not live in the sequencer.
- Con: Apollo is AI in the hands of a rep, not an SDR that runs without one. If you want an unattended meeting booker, this is the wrong row, and Solo or Instantly is the closer match.
- Con: Organization requires a three-seat minimum, so a two-person startup that needs SSO pays for a third seat it does not have. That is why the tier is not the startup default, and Basic is the plan to quote until a third person exists.
Apollo.io's pricing is fair for a sales intelligence and outreach platform.
Reply.io
Jason, Reply's AI SDR, for a team that has outgrown a sequencer and can start from the published AI SDR price.

- 4.3 on SourceForge (67 reviews)
- Starting price
- From $500
- Free plan
- Yes
- Rating
- 4.5 (1,621 reviews)
Best for: Teams that want a named AI SDR with autopilot or co-pilot, and already know Reply's multichannel product.
- Pro: Jason is a separate hire with realtime contact search, intent, AI personalization, and AI replies, and you can run him in co-pilot or autopilot. The price starts from $500, which is a floor for the AI SDR and not a finished quote.
- Pro: The platform trial is 14 days and includes the database, multichannel sequences, and AI features for templates, so you can judge Reply before you add Jason. Email-volume plans start at $49 per user per month on the annual view, and that seat price is not the AI SDR.
- Pro: Reply syncs Salesforce, HubSpot, Pipedrive, Copper, and Close directly, so a startup on one of those does not need middleware. Engagement plans include 50 live data credits a month, so data is metered apart from Jason, and the Reply.io profile covers the rest.
- Con: Contacts, mailboxes, and the billing term are not published next to that starting price, so get the order form before you compare him with Solo.
- Con: On the email-volume plan, LinkedIn is a per-account add-on and calls plus SMS are another, so the seat you saw is not the multichannel bill.
Reply.io's pricing is competitive, especially with its generous free tier offering 200 emails/month and AI writing.

- 4.6 (148 reviews)
Best for: Post-fit B2B teams with a deal size that can carry a dedicated agent plus mailboxes.
- Pro: The pricing card is $499 a month, billed quarterly or annually with two months free on annual, for 1,000 active contacts. That pace is about 2,000 to 2,500 new leads and 6,000 to 7,500 emails a month, which is a working motion rather than a pilot.
- Pro: Auto-pilot and co-pilot both ship in the product, in 20 or more languages, so a second language does not mean a second vendor. A 500 million contact search and a dedicated account manager are included, and you do not buy a separate Salesforge seat to watch him.
- Pro: Above 2,000 contacts in a month the rate is $0.25 per contact, so a list past the included set changes the bill. Personalization can use the prospect's site, blog, or LinkedIn posts, and the Salesforge profile covers the sequencer beside him.
- Con: A quarterly start is also listed at $599, so confirm which figure is on the order form before you compare him with Solo.
- Con: There is no free trial, infrastructure is extra, and Frank is a poor fit before product-market fit. This is not a tool for discovering whether anyone wants the offer. Infraforge starts at $33 a month, billed annually, for 10 mailboxes, and warmup takes two weeks on top of the card price.
Salesforge's pricing structure is generally fair, offering a clear progression from basic email outreach to comprehensive AI-driven sales.

Potential add-on for Email Infrastructure with Agent Frank
Amplemarket
A published Startup plan with two seats, multichannel sequences, and AI agents, tied to an annual term.
- Starting price
- From $600/mo
- Free plan
- No
Best for: A two-person sales team that wants data, sequences, and agents on one annual Startup plan.
- Pro: Startup is $600 a month on an annual term, with two users and 27,000 contacts, plus multichannel sequences and AI intent signals. Every plan includes a trial, so you can see the product, but the term is still annual once you stay.
- Pro: The agents find buyers, research prospects, and personalize outreach, and Duo Copilot plus Duo Copywriter are there for the rep who still edits.
- Pro: Growth moves to a custom quote at four users and 140,000 contacts. A third and fourth seat means a sales call rather than a checkout. Elite is custom at 10 users and 400,000 contacts, and the Amplemarket profile is the directory page beyond that.
- Con: The term is annual, so this is not how you learn whether outbound works, and the monthly experiment belongs on Solo. Buy this after meetings are already happening, not while you are still testing the offer.
- Con: The next tier publishes no price, so a third and fourth seat become a sales conversation instead of a checkout. That step is sharp for a company still hiring its first AE, which is a reason to stay on the published Startup plan.
Amplemarket's pricing for the 'Startup' tier at $600/month is on the higher end for early-stage companies, especially with only 2 users included.

Best for: Technical founders who will build lists, enrich them, and send from Clay rather than turn on an autopilot.
- Pro: Free includes 100 data credits, 500 actions a month, unlimited seats, and Claygent, which is enough to learn the workbook and not to run outbound. The email sequencer is included, capped at 200 rows per table, so sending from Clay stays a small test unless you upgrade.
- Pro: Launch starts at $185 a month for 2,500 data credits and 15,000 actions, with phone enrichment and signals, which is enough for a real list. Data credits start at $0.05, and a lookup that returns nothing is not charged, so failed searches do not spend the pack.
- Pro: Growth starts at $495 a month for 6,000 data credits and 40,000 actions, and it adds CRM sync plus buying domains for the sequencer. Action packs are also listed from $60 a month, so match the cart to the FAQ figure before you pay.
- Con: Clay is a system you operate, so a non-technical founder spends the month building tables, which is the month an agent was supposed to save.
- Con: Actions reset every cycle and do not roll over, while data credits on Launch and Growth can bank up to twice the monthly amount. Budget the action cap rather than only the credit pack, or the limit that sends will run out while credits remain.
Clay's pricing starts reasonably with a generous Free tier, but scales up quickly.

Best for: Startups with a proven offer that will run a demo and accept a quote with no public price.
- Pro: Ava finds leads, writes outreach, handles replies, and books meetings, so she replaces a BDR's week rather than a single copy step. Every tier includes 250 million verified contacts and two-way Salesforce and HubSpot sync, so the CRM connection is not an upgrade.
- Pro: You can require approval, lock tone and calls to action, and set banned phrases, so a fragile brand can fence the voice. Emails go out in a rep's name from your domains, which means the founder still owns the meeting Ava booked.
- Pro: Team, the entry scope, contacts about 2,500 leads a month. That is a serious motion, and too large for a message you have not settled. Scale is about 6,000 leads and adds a dedicated CSM, which the Artisan profile tracks for teams already at that size.
- Con: No dollar is published, and Team, Scale, and Enterprise are scoped to lead volume, mailboxes, and dialer seats before you ever see a price. If you need a number before a demo, skip this row and stay with a plan that prints an entry price.
- Con: The AI dialer is a per-seat add-on, so calling is not inside the email quote you will be shown. The entry volume is more first touches than an unsettled message should send, which makes the tier larger than a pilot.
11x
Alice, a managed outbound worker with mailboxes included, for a funded team that can sign an annual plan.
- Starting price
- From $3,750/mo
- Free plan
- No
Best for: Funded teams that want a managed SDR worker and can commit to the published annual plan.
- Pro: Alice Growth includes up to five end users and 2,000 new prospects a month. Managed Gmail mailboxes, domain setup, warmup, rotation, and CRM sync come inside the price. The published year starts at $36,000, which is not twelve months of the monthly rate on the card. There is no setup fee on top of the annual price.
- Pro: Price is per prospect, not per email, so a longer sequence does not raise the bill the way a credit meter would. Pro is a quote at 5,000 prospects and adds 105 or more languages, which you do not need until Growth is too small.
- Pro: Non-renewal takes 30 days of written notice, and renewal increases are capped, so put the notice on the calendar if you want the year to end. Julian, the inbound worker, is a separate contract, and 11x alternatives is the comparison if this annual shape is wrong.
- Con: Annual billing is the default, so a pre-seed company that needs a month of evidence should not start here. Alice is a real agent, and the contract is still a hire rather than a test you leave after a quiet month.
- Con: Inbound voice is a separate product and is not included in Alice's price, so do not expect calling inside this plan.
What an AI SDR agent is
An AI SDR agent finds people, writes the outreach, sends it, and tries to book a meeting. A sequencer only sends a sequence a person already wrote, so you still own research and the first draft.
AiSDR, Instantly's AI Sales Agent, lemlist's lemAgent, Reply's Jason, Salesforge's Agent Frank, Artisan's Ava, and 11x's Alice are agents in that first sense. Apollo and Clay can research and send, but a human still owns the judgment, so they fit a founder who reads every first email.
Why the contract matters more than the autonomy demo
Results are strongest after about six weeks, and warmup for several inboxes takes 30 days or more. A 30-day annual pitch is the wrong shape for that ramp, which is why Solo stays on a monthly bill.
Explore, the next tier, is $900 a month on a quarterly contract for 800 contacts, so skip it until Solo produces replies. Organization on Apollo is $119 per user per month on annual billing, and a three-user minimum puts the floor at $357 a month. That floor arrives before you have three people, so a two-person startup should not treat Organization as the price to beat.
When you still want to drive the database yourself, read Apollo vs Instantly before you put an agent on top. When the job is really sending, use the cold email guide instead of hiring a worker.
Key Features to Look For
Cancel window (Essential)
Solo runs month to month, while Explore and Scale are quarterly, so moving up is a new commitment rather than a bigger allowance. Alice bills annually and needs 30 days of written notice to skip renewal, which a startup should refuse until the offer is proved.
Mailboxes in the price (Essential)
AiSDR and Alice include setup and warmup, so the first month does not require a separate deliverability vendor. Instantly includes unlimited warmup on the outreach plan, which covers a team that already sends. Agent Frank leaves infrastructure out, and Infraforge starts at $33 a month, billed annually, for 10 mailboxes you still have to buy.
Approval mode (Essential)
Instantly, Agent Frank, Jason, and Ava can hold sends for a human, and AiSDR can reply in co-pilot mode. Turn autopilot on only after a week of approved copy, because the first ICP is usually wrong.
LinkedIn in the entry plan (Important)
AiSDR Solo includes one LinkedIn account, so a founder who needs that channel in week one is already inside the entry price. lemlist puts LinkedIn on Multichannel rather than the Email plan, and Reply sells it as a per-account add-on on the email-volume plan. The quote you saw may omit the channel you meant to run, so ask before you compare.
CRM you already have (Important)
Most early teams are on HubSpot, and AiSDR Solo includes native two-way HubSpot sync, so that stack does not wait on a higher tier. Salesforce sync arrives on Scale, so a Salesforce startup is not a Solo buyer, while Alice includes bi-directional CRM sync on every published tier. A tool that only exports a CSV will fork your pipeline, and someone has to reconcile that export with the CRM by hand.
What to weigh before a founder signs
-
If nobody has sent this offer by hand, buy a sequencer with an approval queue, because a managed worker will scale a message you have not proved.
-
Price the mailbox layer separately when infrastructure is extra, or the entry price you compared is not the bill you will pay.
-
Match the meter to a monthly contact target you can name, then stop, because unused capacity on a quarterly plan is not a discount.
-
HubSpot versus Salesforce changes the AiSDR tier, so confirm the CRM before you compare entry prices or you will quote the wrong plan.
Evaluation Checklist
Name a monthly contact target before the demo, and write down which unit the vendor meters: contacts, credits, active contacts, or leads contacted.
Ask whether warmup and domains are inside the price, and add Infraforge or bring-your-own before you compare if they are not.
Confirm HubSpot or Salesforce on the tier you will actually buy, not on the enterprise slide, or the entry price is the wrong quote.
Turn on approval mode for the first 20 sends and read them, because a wrong ICP only gets louder once autopilot is on.
Check whether cancel is month to month, quarterly, or annual with notice, and match that clause to how sure you are that outbound works.
Put the same 25 accounts through two finalists and compare replies, not the homepage meeting claim, because the demo is not your ICP.

Mistakes to Avoid
- ×
Buying Explore because Solo looks small swaps a monthly test for a quarterly commitment, so stay on the monthly tier until replies are real.
- ×
Quoting Instantly's outreach plan as the agent price misses the credits the agent spends, and the Starter bundle is the line that includes both.
- ×
Putting a new domain on autopilot in week one skips warmup. Several AiSDR inboxes need 30 days or more, and Frank needs two weeks.
- ×
Choosing Artisan or Alice from a demo reel, before a person has sent the offer, is the wrong buy. Their entry volumes assume a motion, not a hypothesis.
- ×
Using Clay as if it were an employee fails. The free plan is a workbook with a sequencer, and someone on the team has to run it.
Expert Tips
- →
Send the offer yourself for two weeks, even badly, so the agent copies a message that already got a reply instead of inventing the positioning.
- →
Keep the first agent on approval mode until the ICP fields stop changing, or you pay to send a definition you are still editing. Instantly will not spend credits on a recommendation you reject during wake-up, which is the right default while those fields move.
- →
If the CRM is HubSpot, shortlist Solo, Clay, and any tool that syncs HubSpot on the entry tier. Do not pay for a Salesforce-only step you will not use.
- →
When the choice is a database you still drive, read Apollo vs Instantly and the sales engagement guide before you add a worker.
- →
Judge the month on positive replies and meetings, keep a spare domain, and leave the primary domain off the agent until placement looks normal.
Red Flags to Watch For
-
A vendor that leads with emails sent, rather than meetings from a named ICP, is showing the metric that burns a young domain.
-
An annual contract on a product you have not watched approve 20 emails skips the ramp, which these vendors measure in weeks, not a weekend.
-
A dialer, LinkedIn seat, or mailbox pack that shows up after the proposal was an add-on, so put it in the price before you sign.
-
Two prices on one page, which is the current state of Agent Frank's card and FAQ, should not be averaged into a single budget.
-
A startup tier that includes thousands of leads a month is a scale plan with a friendly label, not a pilot you can afford to get wrong.
The Bottom Line
Start on AiSDR Solo if you want an agent, a mailbox stack, and a monthly cancel. That shape fits while the offer is still a hypothesis. Start on Instantly if the budget is the Starter bundle and you can live with a credit meter and a low daily cap.
Use Apollo or Clay when you still want to approve the words. Use lemlist when you want a 14-day trial before you pay for LinkedIn. Move to Jason, Agent Frank, or Amplemarket only after the offer already books meetings, because those plans assume a motion you have proved.
Leave Artisan until you can accept a quote sized in thousands of leads. Leave Alice until an annual worker is a hire you have decided to make.

Frequently Asked Questions
What is the best AI SDR agent for startups in 2026?
AiSDR is the best default for a startup in 2026, and Solo is $250 a month, billed month to month. The plan covers 200 AI-researched contacts, three mailboxes, one LinkedIn account, and HubSpot sync, so the first stack does not need an annual lock. Instantly is the lower bill if you already send cold email, and Apollo is the pick when a person should still approve every email. Alice is a later hire, not the first contract, because she is an annual worker rather than a month you can cancel.
How much does an AI SDR agent cost for a startup?
Verified in September 2026, the self-serve path is Instantly's Starter bundle or AiSDR Solo, both priced in the table. lemlist's Email plan is $55 a month on yearly billing, Jason starts from $500, and Agent Frank's card is $499 a month. Amplemarket Startup is $600 a month on an annual term, and Alice's card is $3,750 a month billed annually. Alice is also published at $36,000 a year, those two figures do not match, and Artisan does not publish a dollar.
Is there a free AI SDR agent for startups?
There is no serious autopilot with a forever-free plan in this set, so the free offers are a database sample or a workbook. Apollo's free tier includes 900 credits a year and two sequences, and Clay's free plan includes 100 data credits, 500 actions, and the sequencer. Instantly includes 1,000 credits to try its agent, lemlist and Reply run a 14-day trial, and AiSDR and Agent Frank offer no free trial.
AiSDR vs Instantly: which should a startup buy?
Buy AiSDR Solo when you want research, email, LinkedIn, and warmup in one monthly plan, at the Solo price shown in the table. Buy Instantly when the Starter bundle is the budget and you already have sending accounts in place. You spend five credits per lead, and the default cap is 10 sends a day, which is the limit Solo does not impose. Instantly is the sequencer that grew an agent, and AiSDR is the agent that includes the sequencer.
Can an AI SDR replace a founder who is still selling?
An agent can take research, first touch, and follow-up, but it should not invent the offer, or a weak message goes out at volume. Salesforge calls Frank a poor fit before product-market fit, and Artisan still sends in a rep's name, so the founder still owns the meeting. Use approval mode until the replies look like something you would have sent, and only then consider letting it run.
What contract should a startup refuse?
Refuse an annual worker before a human has booked meetings with this offer, because the first test should be a month you can leave. Alice bills annually, and the card does not match the published year, so you cannot take a single number off the page. Explore is quarterly at $900 a month while Solo stays month to month, and Apollo Organization requires three users before you can buy it. Artisan's Team scope is about 2,500 leads a month with no public price, and these are scale choices rather than a first test.
Do AI SDR agents include email warmup?
AiSDR includes warmup and mailbox setup on every plan, and Instantly includes unlimited warmup on outreach plans. Neither one sends you out to buy a separate warmup tool. Alice includes managed mailboxes, warmup, and rotation, which is the same coverage on an annual contract. Agent Frank does not include infrastructure: Infraforge starts at $33 a month, billed annually, for 10 mailboxes, and warmup takes two weeks. Clay can buy domains on Growth for the sequencer, and that purchase is not a reason to skip the warmup window.
