Buyer's guide
Writing Apps for Startups: what to know
Startups (pre-PMF to Series A) optimize for two things software-wise: speed to ship + low fixed cost.
The trap: is over-investing in enterprise tools (Salesforce, Workday, NetSuite) too early when free + freemium tiers cover 80% of the need. The pre-seed / seed startup stack: HubSpot Starter or Pipedrive (CRM), Loops or Customer.io (email), PostHog free tier or Mixpanel free (analytics), Linear (project mgmt), Vercel + Supabase or Railway (hosting + DB), QuickBooks Online or Xero (accounting), Mercury or Brex (banking + cards), Rippling or Gusto or Deel (payroll + HRIS). Total monthly software spend pre-PMF: $200-500. Series A+ adds: Stripe Billing + Maxio for subscriptions, dedicated DPA/security tools (Vanta, Drata), proper CDP (Segment, RudderStack). The single biggest leverage: pick tools your future $10M-ARR self will still use. Migration costs at $5M ARR are brutal.
Challenges Startups face
- Tool migrations at scale ($1M → $10M ARR) cost weeks of engineering
- Free tiers expire abruptly; budget shocks hit Series A
- Founder + engineer doing CRM data hygiene is unsustainable past 50 customers
- Investor reporting requires data from finance + product + sales — usually pulled manually
- Security questionnaires from enterprise prospects require SOC 2 + DPA earlier than expected
What to prioritize when picking a tool
- CRM that scales from 10 to 1000 customers (HubSpot or Salesforce + Endgame for PLG)
- Analytics tool that survives the migration from free to paid
- Stripe + subscription billing tool that handles your future pricing
- Accounting that scales from QuickBooks to NetSuite-class
- Security + compliance toolchain (Vanta, Drata) before enterprise sales hit
