Jason Gershenson
Startup and venture capital counsel for founders, investors, and companies moving fast.
I advise on the legal issues behind building, financing, and running a company. I've also founded and exited a venture-backed technology company.
About

I'm a New York-based business attorney working with founders, companies, investors, and individuals across the U.S. and internationally. My practice spans venture financings, commercial agreements, governance, equity matters, M&A, and outside general counsel support.
Common reasons clients reach out
View focus areas- A financing is moving quickly, but the cap table, equity documents, approvals, or older company records need work.
- An important customer, vendor, or technology agreement needs to get signed without giving away unnecessary leverage.
- You're weighing a startup offer, founder equity, or a change in role and want advice on your own equity and employment terms.
- A growing company needs ongoing corporate and commercial counsel, but not a full-time general counsel.
Startup Counsel
You Were Offered 10% of a Startup. What Does That Actually Mean?
An equity percentage tells you little until you understand the instrument, the calculation, the vesting terms, and the documents supporting it.
Outside General Counsel
What Outside General Counsel Actually Does for a Startup
Outside GC support becomes useful when legal questions stop being isolated documents and start showing up across contracts, hiring, governance, financing, investor requests, equity, and strategic decisions.
Financing Scenarios
Cleaning Up Early SAFEs Before a Real Financing
SAFEs are easy to sign. They become harder to clean up when the company needs institutional money, a clean cap table, or a more formal governance structure.
