From scrappy startups to pre-IPO powerhouses, finance teams evolve fast—and not always in a straight line. We analyzed the org charts of 218 high-growth Y Combinator companies to answer the questions finance leaders ask most:
‍

• When should we hire our first FP&A lead?
• How big should the team be at 250 employees?
• When do specialized roles like Treasury or Procurement appear?
• How does accounting headscount scale compared to strategic finance?
  ‍
  

Inside, you’ll get a data-driven roadmap of how finance organizations evolve across four key stages: Early (5–50 employees), Growth (51–250), Scale (251–500), and Pre-IPO (500+) stages.
