Another win for the team, we're on fire. Thank you
Excited to share that Vesto has joined @tryramp .
We started Vesto with a simple vision: give finance teams one place to manage all their cash.
Since then, we’ve helped hundreds of teams bring their treasury operations across banks, entities, and countries into one platform.
I’ve long admired what Ramp is building, and as I got to know the team better, it became clear that joining forces would let us bring this vision to life at a much greater scale.
At Ramp, we’re now building one place for finance teams to manage their cash alongside their spend, no matter who they bank with.
We’re starting by bringing bank connectivity, cash flow reporting, and forecasting together, giving teams a complete view of their cash in the finance platform they already use every day.
To the customers who’ve trusted Vesto over the years: thank you. Building for you has been the best part of this journey, and your feedback continues to shape what we’re building next.
I couldn’t be more excited to keep going with the team at Ramp. Job’s not finished.

I built a living model of all our funds, synced from Carta via MCP. Change anything... an exit, markups, markdowns... the whole book reprices instantly. NAV, TVPI, per-partner carry, return-the-fund math.
GPs: want this? DM me. Runs locally. Your data never leaves your office.
The best

Introducing the Meadow.
Leave your phone at home, and make some memories.
Pre-order at the link in our bio.
New life goal dropped. Thought I had to be dead to be on founders….until now
Nine years ago, I launched Founders (@FoundersPodcast).
Today, I'm launching a new podcast called David Senra.
The first episode goes live this Sunday. Subscribe wherever you watch or listen to podcasts.
Founders will still come out every week.

IN NEWS: Cubby raises a $2.75M seed round.
We spoke with founder @trumansacks1 about the product and why law students will pay for it.
“Law school is a knockout, drag-out fight… firms see the rankings.”
“The mindset is: I’ll invest in my future. Anything that helps me do better is an investment.”
Cubby is the AI teaching assistant for law school students, trained on thousands of practice exams and case briefs, with a Duolingo-style experience calibrated to your course and professor.
“We built an experience that mirrors how your specific professor teaches, because that’s who decides your grade.”
Day 1! Come say hi if you are in NYC this week! 🏇
Excited to share we’ve raised $2.75M for @CubbyLaw from @LudlowVentures, @SamHinkie, and @PSUMVC.
We’re building the first AI teaching assistant for law students, powered by our own legal intelligence model trained on thousands of professors’ syllabi, past exams, outlines, and grading rubrics.
Cubby started as a horizontal AI research tool, but when law students began adopting it fast, we went all in.
Law school prep is broken:
• Curve-based grading
• 100+ hrs building outlines
• Legacy tools students still pay thousands for
Cubby brings it all into one connected workspace: case briefs, outlines, and practice exams, calibrated to how your professor teaches and tests.
Law school is our first step toward a new era in legal tech.

Oh and our team is fucking cracked - I've been having the most fun I've ever had in my entire life.
The future is bright.

If you know exactly how to solve a problem, it's probably not high impact. Real progress comes from tackling problems where you don't even know where to start.
@rabois @jeff_weinstein explain this idea well
Truly blessed to be able to work with Ludlow every day. Rare to consider two internet strangers family so quickly after meeting.
Excited to launch Ludlow Fund 5 with @BrettdeM. We are beyond blessed to work with incredible entrepreneurs and amazing LP’s. I hope we get to do this for a very long time.

@trumansacks1 and I have watched this 200+ times

Quick thought:
The avg person meets 80k people in their lifetime - 0.001% of the population. Humans *literally* cannot fathom 8bn people.
If you face the problem, build & ship it. There’s a market. Go niche 🐎
Today marks 2 years & the end of my time @stockx.
Extremely thankful for the friends, meaningful work, and growth they’ve provided me through the very end.
Excited for what’s next. The future is bright 🐎
this along with @sama’s blog.samaltman.com/how-to-be… feel important for those trying to thoughtfully plan out their years
