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
