Today, I’m proud to announce @DayOneVC’s $150M fund III that brings our AUM to over $450M.

Our north star remains the same: we will keep betting on the most exceptional founders of our time working on the biggest ideas possible.

Big fan of Atlas as one of their first customers—it’s the number one fintech consumer product of our time since Robinhood and Revolut.

An even bigger fan as an early investor who kept betting on them through some insane pivots.

We’re proud to announce our $40M funding round led by @eladgil and Verified Capital, alongside @01Advisors and @MarathonMP. This capital will expand our foundation, advancing in-house technology and operations, and enhancing our dining, lifestyle and travel offering.

NEW: Four years ago, fintech startup Atlas looked like it was on the brink of collapse. Today, tech billionaires are lining up to pay $1,000 a year for its card: https://t.co/fY1nKgTMDl.

Today @YuzuHealthInc announces our Series A!

Our mission is to bring trust and agency back to health insurance.

Thank you to our customers, partners, and team who made this possible!

Blog and hiring link in the comments.

[Masha Bucher @mashadrokova]

Yuzu is one of the steadiest, most consistent and driven teams I’ve worked with, and masters of compounding. It attacked health insurance with first-principles innovation to bring it into the modern age and make healthcare accessible as a result. Lucky to be an early backer.

[Avante Price @AvantePrice]

I'm excited to announce Posh’s $37M Series B, led by @FirstMarkCap.

6 years ago, people told us a better events platform was a solved problem. 8m users and $350M in GMV later, we're just getting started.

Excited for this! I think it is by far the most interesting approach of any BCI effort.

[Masha Bucher @mashadrokova]

The next era of humanity begins with merging mind and machine —unlocking our ability to create without limits and true agency.

No team is better suited to realize this future. Thrilled to back @merge and join forces again with Alex, Sam, Sandro and their brilliant co-founders.

Leaving waiting on hold in 2025

Tivara is fixing the front door of healthcare—proud to be backing @tejseelamsetty & team

[Tej Seelamsetty @tejseelamsetty]

1/5 America spends $450B a year on healthcare admin, yet patients still wait an hour on hold. Phones ring nonstop. Medical front desks are understaffed.

We built Tivara to fix it
Launching publicly today 🧵

Today we're launching Agentica: an open-source SDK (Python + TypeScript) and the @Symbolica Platform for running typed, multi-agent workloads in production.

Agentica starts from a simple premise: code is the most expressive interface through which models can interact with their environment. That shift helped a simple Agentica agent hit 77.11% on BrowseComp, a new state of the art…. and only took a few hours of time from one person on our team.
