Most companies slow down at scale. Ramp is accelerating. 70,000 businesses now run on Ramp. AI agents are becoming part of the finance team. And @RampLabs is shipping frontier experiments every week. Today: $ 44B. The next chapter of finance will be agentic and we’re building it.
Today, Ramp raised $750M at a $44B valuation. Last time we grew this fast, we were 1/20th the size. For 2000 years, business was built on two pillars. Today, a third: intelligence. It’s your least governed cost. It’s also your single greatest opportunity.

Today we're launching Stack — the AI operating system built for accountants. Up until this point, Ramp was known to be a spend management company designed for finance teams. That changes with Stack. Stack automates your accounting. It learns your accounting process — how you close, how you reconcile, how you post journals for each client — and runs agents to do the work autonomously. Every action logged and fully auditable. The result is 50% decrease in close time. It's available today for any accountant, whether you run on Ramp or not, anywhere. Know a CPA? Tag them in the comments — and I will personally reach out to them and get them set up with 3 months of unlimited complimentary access.
Introducing Stack. The AI operating system that lets accounting firms take on more clients without hiring. Learns your firm's process, runs the close, posts the journals. Fully auditable. We’re living through the biggest shift in accounting since the spreadsheet.

as a vc, i spend a lot of time researching new industries ai helps accelerate this but still hallucinates a lot @sacrainc built an agent i can interact with via mcp / slack / email that pulls in data from their proprietary database of ~1,400 top private companies (revenue reporting, memos, interviews with founders and leadership, news) that just changed how i get research done and helped me make the shift from passive consumer -> power user what's cool is their analysis layered on top of qualitative and quantitive data over time that said i'm late to the party...their mcp has already fielded >300k requests in the last couple of months

The internet keeps getting more polished, optimized, and generated. Less human. The creators who endure all have one thing in common: people keep coming back to them. We rebuilt Podia for those creators, and the new Podia is live today 💛 podia.com/articles/meet-the-…

Every AI tool just waits for you to type a prompt. For the last year we built the opposite: an assistant that already did the thing before you wake up. Here's what that looks like in a real family. Mine. 👇

I’ve seen a lot of questions about USVC, AngelList’s newest product. First, don’t invest in venture capital if you can’t afford to lose your money. Put your savings somewhere safer. But if you’re considering USVC, here’s a thread that answers the most common questions and explains how it works:

Everyone wants a “Slack built from scratch” to better cowork with agents, and @andocorporation is building it. I spent a month with them to write a deep dive piece on Sara's story and the Ando product (the first public piece about their product, ever - no pressure!) Here it is! 💫 I write about: - @saradu’s 2x founding journey from Alloy to Ando, couchsurfing across hacker houses in SF - making workplace chatter ‘ergonomic for agents’ - architecture-inspired design principles - early alpha customers experience with ando This was incredibly fun to write, thanks to many walks, office visits, and conversations with @saradu, @ryanharaki_ , Jordan, Oliver, @sofiadolfe from Index, and the wider Ando team.

They say your phone knows more about you than your mom. So why can't Siri tell me things like how much I spent on food delivery this month? DM me if you want to try a phone that can.

Nothing gets me hyped like a reaccelerating top line Incredible work @zachperret and @Plaid I also think plaid has a lot of opportunity to eat in the AI prosumer space for financial service apps. Many friends already trying to vibe code personal software. Plaid has tailwinds. Shoutout to the goats at @sacrainc - @smalter @janerikasplund

Something I've wanted to build since day one: a private markets experience that actually feels like a consumer product. Today, the @AugmentMarkets app is live on the App Store. Track your watchlist. Monitor the Power 20. Get private market intelligence wherever you are — not just when you're sitting at a desk. We built this for investors who think about their private holdings the same way they think about their public portfolio. The information should be just as accessible. Get it here: apps.apple.com/us/app/augmen…

I spent 8 years scaling Discord and got burnt out cause modern work is broken. We’re overwhelmed with too much info across apps, teams, and agents. AI made it worse. We’re building the solve. I've joined @tryhighlight as CEO and we raised a $40M Series A led by @KhoslaVentures.
