a16z's David George on the Most Controversial Bet at a16z & Do Margins and Revenue Matter in AI?
a16z Growth GP David George argues mega-fund returns are vindicated by data, AI margins deserve a pass, and Flow/Adam Neumann is a strength-of-strengths bet.
- a16z’s best-performing fund is a $1B vehicle: Databricks alone returned 7x the fund; Coinbase returned 5x DPI.
- 47% of IPO dollars (2017–2025) were gained from seed to Series B; 53% from Series C and later — later-stage returns are underappreciated.
- CH Robinson (truck brokerage) showed 40% productivity gain since end-2022 and 680 basis-point operating margin expansion from AI, cited as proof of real labor-to-tech spend shift.
- On AI app gross margins: a16z now gives a pass on thin margins; if an AI company pitches with SaaS-level margins, it signals users aren’t actually using the AI features.
- David George missed Anthropic at the growth stage — names it alongside Revolut as his most painful errors of omission.
- Flow/$300M Adam Neumann bet is justified by strength-of-strengths thesis: average US renter spends 30% of disposable income on rent, yet renting is the only unbranded major consumer experience.
- Waymo is 7–10x safer than human drivers per NYT op-ed by a medical professional; George compares the safety data to a clinical-trial fast-track threshold.
- Number of US public companies has halved in 20 years; Russell 2500 ROIC declined from 7.5% to 3% over 30 years — private markets are now the quality asset class.
