a16z Bio + Health Fund
Andreessen Horowitz's fund at the convergence of biology and technology.
This is a16z trying to buy their way into healthcare credibility, and it's actually working pretty well. The partners are solid — Vineeta knows her stuff technically, Julie has real operator experience, and they're building a legitimate healthcare network. They move fast when they want something and can write big checks, but you're getting the full a16z treatment: high expectations, lots of portfolio company cross-pollination, and pressure to think big. The flip side is they sometimes push companies to scale too aggressively before product-market fit is locked in. If you want maximum acceleration and can handle the intensity, they're legit.
- —Best for: Technical founders who want to scale fast with serious capital
- —Watch out for: Pressure to grow before PMF is solid
- —Known for: Strong technical diligence and healthcare network effects
