a16z just announced their newest fund - $15 billion! I had @bhorowitz on Uncapped to discuss how they run the firm, how he thinks about venture talent, a16z's overall investment approach, deploying capital at scale, media, and more. He's easily one of the most impressive people I've gotten to have on the podcast. Hope you enjoy.

@jaltma @bhorowitz Excellent conversation

@jaltma @bhorowitz Only thing they know how to scale is AUM and their management fees. x.com/alphanomeai/st…

@jaltma @bhorowitz Yes 👏

Does Marc keep Ben in a closet? Sometimes he says wonderful things that appear to be totally disconnected from reality. “We’re not interested in heat seeking” “We’re not just trying to be in the few big winners” “We don’t want to go public because it will incentivise us to maximize fee income” It’s like he’s running a wonderful venture firm in his head that has nothing to do with a16z today.

@jaltma @bhorowitz Is Jack Altman the brother of Sam Altman? Asking for a fren

@jaltma @bhorowitz The network to be confident. That’s good. Someone asked me this last week about a16z and what it’s like working with them. Here’s what I wrote.

@jaltma @bhorowitz Ben is the bushido 🐐

@jaltma @bhorowitz Huge congrats to a16z on their new fund! $15 billion is a massive milestone. Would love to hear more about how you see venture talent evolving to support this scale.

@jaltma @bhorowitz Such is a fun convo Jack & Ben. And major props on the fund to back more talent

@jaltma @bhorowitz 15b fund is massive. bhorowitz on uncapped sounds epic

@jaltma @bhorowitz hey jack, i made you a thumbnail for this episode with ben horowitz

@jaltma @bhorowitz Love this

@jaltma @bhorowitz watching how top investors think > reading their blogs. uncapped hits different

@jaltma @bhorowitz This is mind blowing

@jaltma @bhorowitz @jaltma,

@jaltma @bhorowitz The best partnerships often function like a producer and a star, where one person's role is to maximize the unique talents of the other. Full episode notes here if you prefer reading! podchemy.com/notes/uncapped…

@jaltma @bhorowitz Thanks for sharing, did you see this coming, or was this bigger than you expected?

@jaltma @bhorowitz do tell more!

This is the part young founders often miss. When a16z raises $15B, it’s not just capital it’s a system: talent, networks, media, and the discipline to keep learning at scale. That’s the real lesson. To the next generation: Your passion is not a hobby it’s raw capital. If you stay curious, keep building skills, and refuse to quit when things get uncomfortable, you can turn almost any obsession into value. You don’t need to be perfect. You just need to keep showing up long enough for progress to compound.

@jaltma @a16z @bhorowitz Interesting discussion!

@jaltma @bhorowitz $15B fund is wild. Biggest question: how do you deploy at that scale without watering down conviction? Would love a thread on that 👀

@jaltma @bhorowitz Crazy this type of content is free

@jaltma @bhorowitz Awesome thanks

@jaltma @bhorowitz „There are no talking points in this world“ 💚

@jaltma @bhorowitz sounds like a big deal! that's a lot of zeroes!

@jaltma @bhorowitz Really enjoying this thus far.

@jaltma @bhorowitz $15 billion is either going to produce the best returns in venture history or become a masterclass in why mega funds can't beat the S&Pprobably find out in 2034

@jaltma @bhorowitz we’re finally getting more of Ben! 😃

@jaltma @bhorowitz @ShaneMac It sounds like you had a meaningful conversation about a16z! Their reputation for building strong networks really stands out. Would love to hear more about your experience working with them. Any insights to share?

@jaltma @bhorowitz Venture capital at scale is the ultimate expression of capital allocation. $15B is a significant concentration of power. This fund will dictate the next cycle of technological productivity. Scale is the only moat.

$15B isn’t just capital — it’s infrastructure leverage. 📊 How a16z deploys capital at scale determines which networks, protocols, and climate-critical systems get built first. Tracking these infrastructure flows is key to spotting where carbon-smart markets and energy systems scale fastest 🌱 We cover this at CarbonFi.io.

@jaltma @bhorowitz Ben’s one of a kind.. the best there is
