@benspringwater @matter I don’t think I ever heard this story, I love this so much! And yes that sounds very @patrickc - like :)

@cjc @daniel_levine The tooth fairy on our side of SF can’t fly through doors 🤷‍♀️so can only retrieve a 🦷 if it’s left hanging in a pouch on the door handle (probably too late for you guys…but pro tip for others who see this 😜)

@amperoshealth raises a $16M Series A led by Bessemer. Excited to see the team hit this milestone!

I sat down with @mmiernowski to talk about his journey, customer relationships, and knowing when it was time to raise the A.

New look for the @uncorkcap website! Same mission, same team, now with fresh paint. We invest before it’s obvious.⤵️

[Andy McLoughlin @Bandrew]

Venture firms rebrand for all kinds of reasons. Sometimes it's genuine evolution - the identity finally catches up with who the firm has become. Sometimes it's camouflage - a way of looking like a different kind of firm than the one the last few years revealed. And sometimes it's just that the old website was embarrassing and someone finally had enough.

Ours is mostly the first, none of the second, and just a touch of the last :)

Today we're launching a new brand and a redesigned website. The logo is refreshed. The palette is cleaner. The typography is sharper. And the site actually reflects how we think in 2026.

@NikMilanovic @Plaid @twifintech Congrats Nik!!

Can confirm 😅

[Brett Berson @brettberson]

Every former company builder joins a venture firm and, in their first week, tries to fix the CRM and other internal systems. It’s a rite of passage.

[Andy McLoughlin @Bandrew]

Delighted to announce @uncorkcap's investment in Mirai (@trymirai), the platform to make on-device inference seamless, fast and multi-platform (Apple silicon today, Android soon).

Mirai’s co-founders, @Darkolorin and @dmitrshvets, independently built Reface and Prisma: early on-device AI products used monthly by hundreds of millions of people globally 🚀

"Today, Claude Code’s run-rate revenue has grown to over $2.5 billion; this figure has more than doubled since the beginning of 2026."

Absolutely insane growth. Doubled revenue since the beginning of 2026?! Today is (*checks notes*)...Feb 12th ��

[Anthropic @AnthropicAI]

Our run-rate revenue is $14 billion, and has grown over 10x in each of the past 3 years. This growth has been driven by our position as the intelligence platform of choice for enterprises and developers.

It's rare to see founders as intentional and consistent about setting up their company's mission, vision, and values for the long haul, even before they've earned a dollar of revenue. Had fun reflecting on the last 4.5 years of Gamma's journey here: https://t.co/NxO2ExPXls

[Amy Saper @amy]

When I first led @Gamma's seed round in 2021, ChatGPT didn't exist. Waymo wasn't yet publicly available. Humans wrote the vast majority of code.

Fast forward to late 2025 when I invested a second time with @uncorkcap, the world had transformed, and Gamma's progress massively accelerated ($0 ➡️ $100M!), but so many things remained the same.

@alexrkonrad This one really hurts 💔
