Senior Partner at Cooley. Advisor to leading technology companies, founders, and investors.

David Peinsipp is a Senior Partner at Cooley and one of Silicon Valley's most respected tech lawyers. He has been inside the boardrooms of some of the most consequential companies of the last two decades—Uber, LinkedIn, Snap, OpenAI, Robinhood, and Zenefits, among others.
Dave's practice sits at the intersection of law and innovation, and his value isn't rules—it's judgment under uncertainty. Great lawyers say "yes, maybe" instead of "no." He's stayed in tech through the AI inflection point precisely because he finds the work meaningful and the relationships irreplaceable.
His philosophy on freedom: it isn't about money—it's about choice. The most liberating professional moment he experienced was gaining the power to walk away from clients who don't align with his values. His reputation and relationships, he says, are his real safety net.
