About
I obtained my B.A. and J.D. from UC Berkeley and am licensed to practice in CA. After graduating in 2023, I practiced law at Gunderson Dettmer, the country's premier startup-focused firm. I represented 50+ VC's and startups in everything from routine… read more corporate matters to $1B+ VC financings and M&A. In mid-2025, I left Gunderson to co-found a media tech company. As a founder, I focus on what is legally necessary for clients to help their business thrive. I avoid needless bureaucracy and utilize AI tools (with robust oversight and review) to efficiently provide high-quality legal work.

Client Reviews
"Seth is very knowledgeable about startup law and gives great advice and insight."
"I worked with Seth extensively on a wide range of matters, including our Series C financing. He handled everything from complex stock purchase agreements to bespoke advisory arrangements, and was always on top of the details regardless of how unusual or fast-moving the situation was. For a company operating at our scale, responsiveness and precision are non-negotiable, and Seth delivered on both consistently. I'd recommend him without hesitation to any early-stage or growth-stage company that needs sharp, reliable counsel."
"Seth handled our conversion from an LLC to a C-corp and structured a share exchange that brought another company under our umbrella. His legal work was foundational to the success of our business today. Throughout the process, he was responsive, efficient, and detail-oriented. Seth is an excellent corporate attorney who we highly recommend, especially if you are early-stage and looking for a quick and capable option."
