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
