Growth

Alex Immerman

David George Posted January 21, 2026

Since we launched our first Growth fund seven years ago, we’ve backed companies that are just at the point of finding product-market fit all the way through to investing at IPO, and we recently announced our latest $6.75B Growth fund to continue to do so. We now manage over $22B across five Growth funds and believe the opportunity to partner with growth-stage companies has never been greater. 

Through it all, Alex Immerman has been instrumental in what we’ve built, which is why I’m thrilled to announce that Alex is being promoted to General Partner on our Growth investing team at a16z.

Alex has been an incredible force since joining the team seven years ago, partnering with founders across consumer internet, enterprise, fintech, crypto, and AI-powered software companies — supporting them from early traction through breakout scale. In the last six months alone, Alex led our new investments in Kalshi, EliseAI, and Revolut, and has partnered with many founders in his time here, including those from Waymo, Stripe, ElevenLabs, Hebbia, Roblox, Anduril, Flock Safety, and many more. 

I’ve had the pleasure of working with Alex for over a decade, dating back to our time at General Atlantic. Those who know Alex know he’s a hustler, in the best way, with great instincts. He has an endless motor, isn’t afraid to speak his mind, and is always willing to help. I’ve also enjoyed seeing Alex become a culture carrier on the Growth team and across the firm.

In his work, Alex has brought deep strategic insight and rigor to every part of the investment process. He’s built strong founder relationships grounded in trust and long-term support, and helped shape our thinking about how great companies win — whether that’s moving beyond surface metrics to durable moats or evaluating what truly drives retention in new software paradigms. 

As a General Partner on Growth, Alex will continue leading investments and working closely with founders tackling some of the biggest opportunities in tech today, with an emphasis on category-defining companies at the intersection of AI, consumer, B2B, crypto, and the physical world.

Finally, to get a feel for how Alex rolls, here are two responses I got from our top CEOs when I asked about working with Alex:

Please join me in congratulating “AI.” I’m proud to call him a partner and am excited for what’s ahead.
