ICYMI: Packy McCormick's 16,000 word deep dive on a16z

https://t.co/YSi2m8Mwzt

“a16z is a Firm. It is a business, a company. It is built with the goal to scale, and to improve with scale. There are many characteristics of a Firm that I believe do not apply to a traditional Fund, and we will cover them. I think this distinction solves one of the oddest things about venture capital’s self-image: that venture capital is an industry that sells the world’s most scalable product (money) to its most scalable companies (technology startups) but must not, itself, scale.

This distinction - Firm > Fund - comes from a16z GP David Haber, the most East Coast Finance of the bunch and a self-described student of investment firms as businesses. ‘The objective function of a fund is to generate the most carry with the fewest people, in the shortest amount of time possible,’ he explains. ‘A Firm is about delivering exceptional returns, and building sources of compounding competitive advantage. How do we get stronger with scale, not weaker?’”

At Andreessen Horowitz, we just raised over $15B.

With these new funds including American Dynamism ($1.176B), Apps ($1.7B), Bio + Health ($700M), Infrastructure ($1.7B), Growth ($6.75B), and other venture strategies ($3B), we raised over 18% of all venture capital dollars allocated in the United States in 2025.

Why did we raise the money and how do we plan to invest it?

I'm incredibly proud that Flock Safety played a key role in working with first responders to find the suspect in the Brown and MIT murders.

America cannot tolerate tragedies like what we saw at Brown and MIT this past week. The single best way to curb crime is to make sure would-be criminals know they'll be caught. Excellent intelligence is the only way to make that a reality, and we intend to continue using technology to make sure our law enforcement are empowered to do their jobs.

[Alex Immerman @aleximm]

If you commit murder in America, there’s a greater than 50% chance you get away with it.

That's why law enforcement needs tech like @Flock_Safety.

Great listen with @glangley @bhorowitz @eriktorenberg

Congratulations, @guywuolletjr Love watching you soar, and this promotion is so well deserved!

[Chris Dixon @cdixon]

Today we are excited to announce that we are promoting Guy Wuollet (@guywuolletjr) to General Partner.

We first met Guy in 2018 while he was studying computer science at Stanford, where he also rowed varsity crew. He initially joined the firm as an intern working on the enterprise go-to-market team, but it soon became clear he was most passionate about crypto.

We kept running into Guy: first when he joined our Crypto Startup Accelerator to build a decentralized ISP, then while doing research at Protocol Labs, and finally as a teaching assistant for our research partner @danboneh.

After joining us full-time in 2020, Guy began investing in infrastructure, DeFi, and DePIN. He has been a steady and creative force, making significant contributions to more than 20 investments, including Solana, LayerZero, Gensyn, EigenLayer, Daylight, and Morpho.

Based on insights from prior investments like Orchid, Nym, and Helium, Guy defined our thesis on what would become known as DePIN. He wrote one of the defining blogs on why DePIN matters and helped us invest in Gensyn. Next he wrote about decentralized energy and led our investment in Daylight. Guy also invested in decentralized transportation, robotics, and AI projects as he helped run our accelerator.

DeFi has always been central to Guy’s thesis, but his early investment in Morpho was driven above all by conviction in the founders. He recognized in @PaulFrambot and his team a rare combination of technical depth and clarity of vision. Since then, Morpho has grown to billions in total value locked and become one of the leading protocols in DeFi. Their V2 launch marked a major leap forward in efficiency and scale for on-chain lending.

Through his work with founders, Guy has shown a rare mix of deep technical expertise and thoughtful pragmatism. Founders often tell me how impressed they are that Guy systematically reads, understands, and provides useful feedback on protocol design and other hard technical topics. His writing and advice on token and protocol design have helped influence many projects in our portfolio.

Beyond his investing skills, Guy has been a calm and positive presence, with a wry sense of humor, both inside the firm and for founders. As the crypto team grew from a small group to more than 80 people, he helped recruit and mentor many of the talented investors, researchers, and operators who make the team what it is today.

Guy is an invaluable member of the team, and it has been great to see him grow and develop over the last five years.

Guy joins me, @alive_, and @AriannaSimpson as @a16zcrypto’s fourth General Partner.

Congrats to @arielcoco, @itwig, and the entire @Navan team.

Navan survived a global travel shutdown when COVID hit in 2020. Their resilience speaks for itself.

We @a16z are incredibly proud of them, and their IPO today is a well-deserved milestone. Onward!

1/ It's time to bring back "designed in California, made in California.”

Today, at @reindsummit, @ashleevance and I introduced Solano Foundry, the largest advanced manufacturing park in America, an hour north of Silicon Valley. Built by @CAForever with @JLL. 🧵

[David George @DavidGeorge83]

Congratulations to @zoink, Praveer and the @figma team on going public.

When we originally invested, we said we were entering the decade of design.

Amazing how much that has happened. Thanks for letting us at @a16z be part of the journey.

[Marc Andreessen 🇺🇸 @pmarca]

THAT'S RIGHT.

[Stacy D'Amico @stacydamico]

I’m absolutely thrilled to hear this news! Scott is such a principled, incredible leader, and I’m so excited for what this means for all of us Americans. This is a win for everyone - so well deserved @skupor!

[Scott Kupor @skupor]

Thank you @realDonaldTrump for the opportunity to serve our country in helping @elonmusk, @VivekGRamaswamy and the entire DOGE team make efficiency a central tenet of the federal government https://t.co/y4gddhbvub

@skupor @realDonaldTrump @elonmusk @VivekGRamaswamy Amazing news, Scott! I couldn’t be more excited for you and for all Americans - this is truly a time to celebrate! 🇺🇸

Selling is harder now than it was a few years ago, but there are still dollars to win in this new gen AI-native era. Here’s how from @a16z Growth’s @justin_kahl, @DavidGeorge83, and @aleximm via interviews with 30 F500 CIOs and software sellers.

[David George @DavidGeorge83]

1/ Selling's much harder than it was before. Everyone is scrambling to buy gen AI while it feels like the software market is slowing down. The reality is, NN $ up for grabs has been cut in half. But based on convos w/ 30 F500 CIOs & software sellers, there are still $ to win.

[Stacy D'Amico @stacydamico]
