Seed, Venture and Growth Financings
Whether your goal is to form your first company, raise a seed round, close a Series C, or bolster your balance sheet in advance of an IPO, we can help. We have formed tens of thousands of companies and consistently negotiate and close more venture capital and growth financings than any other firm in the world.
While a prolific serial entrepreneur may raise capital a dozen times in a career, a Gunderson Dettmer corporate attorney may negotiate dozens of those deals every quarter — and across a variety of sectors and industry segments. We know how to prepare our clients for what’s next because we have seen what’s next play out time and time again.

We know the entire cast of characters in the VC market — investors, limited partners, funds and firms — and we use this knowledge to counsel our clients.

Gunderson Dettmer Releases 2025 Venture Capital Report
Gunderson Dettmer’s 2025 venture capital report shows a recovering but sharply split market, with AI startups winning a disproportionate share of capital at premium valuations. Non‑AI companies face tougher fundraising as AI tools lower costs, speed development and raise the bar for VC‑backable companies. Later‑stage investors are concentrating larger checks into a small group of frontrunners, often using rounds with secondary components, and just ten companies received more than half of all venture dollars in 2025.
