we’re excited to share that we’ve raised $20M (from Accel, Index, & Emergence) to build the 'ai-native Slack' you've all been craving TLDR; ando is a team messaging platform built fresh, from the ground, up for a world where agents act as real collaborators alongside us. we have teams using us across 15 countries, and spanning industries like software, financial services, real estate, & more request access if any of this resonates 💌

agenthook gives coding agents a webhook-backed inbox. When a deploy, CI job, or another agent/service finishes after an agent’s turn ends, it can notify the agent instead of making the agent block and monitor.

We were really impressed with how fast OAI's new gpt-realtime-2.1 was while still being able to call tools, so we wired it into our OS agent running on my phone. Now I can completely control any app on my phone while I'm biking to work

Today we're launching a whole new Arrows. Every deal gets a gameplan. Arrows gets it done. Why? Because your best reps have a gameplan for their best deals... but it's all in their heads and is executed inconsistently. Until now.

Got some bad news and some good news today. Bad: the claim on our website that @podia creators have earned more than $500M is stale. Good: it's now more than $900M Won't be sleeping through $1B

"Voice agents are built to be helpful. The problem is they can be too helpful and cross the boundary." I sat down with @sumanyu, Founder and CEO of @HammingAI, at our @aiDotEngineer booth. @HammingAI stress-tests and monitors voice agents so the bank or hospital running one catches failures before a customer does. Fresh after his talk “I Monitored Crime Audio. Voice Agents Scare Me More,” we got into: 0:00 how Sumanyu went from listening to 911 calls at Citizen to founding Hamming AI 0:39 why he's more nervous about voice agents than he was about crime 1:51 the first voice-agent security product 3:16 simulating messy reality: accents, background noise, code-switching 4:11 voice agents testing voice agents 5:47 why taking actions is table stakes, and what makes it dangerous 11:07 hot take: everyone rushed to B2B, more founders should build consumer Thanks for coming to our @browserbase booth, @sumanyu!

AI is extremely good at spending your money very quietly. our own token spend went from a rounding error to more than 10% of payroll in a year. one week in May we burned through $1.5 m. our CFO didn't love telling me that number, and he really didn't love telling the internet. but every finance leader we talk to is living the same story. the bill keeps going up and teams can't answer basic questions about it. which team is driving it? which models they're using? what changed this month? whether a cheaper model would do the same job? so finance gets two bad options: keep paying and hope, or cut broadly and slow down the work that's actually compounding. we built a third one. Ramp now connects to OpenAI, Anthropic, Gemini, Cursor and pulls it all into one place. see it, understand it, control it - down to a single API key. built with 1,000+ companies managing 100T+ tokens a month, and now spending less than they expected too! try it today at ramp.com/ai-cost-monitoring

Today we announce raising our Series A and $25M in total funding to do more of the work for the hundreds of companies that trust us with their sales tax and the thousands more we want to serve. Indirect tax is the least sexy, biggest problem in almost every company that sells anything. In the US, businesses remit over $600B in sales tax a year. Globally it's ~$5 trillion in VAT. It never goes away. It only gets bigger. And it lands on people who never signed up for it. Your controller. Your VP of Finance. Your CFO.

a top decile vc friend doesn't do any marketing instead, he treats the intro call as the product, arriving with deep perspective on the market, competitors, and whitespace, and a tight pitch on how his firm will accelerate learning and growth pumped to see the @sacrainc team launch the sacra.com/agent web experience to enable more investors not just to write better memos but be better partners

Eric and I have worked as a team for the past 12 years. This only makes it formal. Strategy decisions are increasingly technology and systems-design decisions, and we want the company built around that reality. Stepping in as CTO is @rahulgs. Rahul's superpower is being right early. He spots the bet worth making while everyone else is still forming an opinion. A lot of Ramp's best decisions trace back to that instinct, and now it's pointed at the whole technical org. @HamidDadkhah3 is taking on a new role as Head of Engineering. Hamid cares about what the customer actually achieved, not what we shipped, and he moves things over the line without waiting to be asked twice. Engineering orgs are supposed to slow down as they grow. Hamid takes that as a personal challenge. Speed compounds. What used to take a year takes < 1 month now. Glad to have these two running it.
Today @karimatiyeh and I are both taking new titles as Co-CEOs of @tryramp. If you know us, this won't feel like a change. From when we first started building together twelve years ago, our partnership has run on a couple of motivating principles. On decision-making, we trust each other completely to make critical calls for the company across every function. And on organization design, technology is not a distinct part of the company - it is the entirety of it. That is why Karim has for years directly managed risk, operations, and marketing. Most importantly, at Ramp there is no line between the people who build and the people who do everything else. Everyone is a builder. For the last 2,656 days, we have run the company this way. This only makes it formal. We thought it was important to do it now because of how we see the AI exponential reshaping what Ramp can be. Decisions of company strategy are increasingly decisions of technology and systems design. We have always believed every function should be approached as a systems-engineering problem (even when the system was primarily human) but the rise of machine intelligence makes this existential. Every part of the company must be positioned to leverage the continued explosion in model intelligence and capabilities. If we do this well, each step-change in what models can do compounds automatically into better products and faster execution without anyone having to rebuild the company to capture it. If we fail to operate this way we will ultimately be outcompeted by a new company that does. We are also making Rahul Sengottuvelu our CTO. @rahulgs has led Applied AI at Ramp since joining us three years ago through the acquisition of his prior company, Cohere. Before that, his first company was building customer-service agents on GPT-3 at a time when almost no one knew what a large language model was, and he has spent every year since pushing the frontier of what existing models can do. He has also been right on nearly every major technical direction in AI well before it was obvious. Building Ramp now means applying AI to every part of it, and Rahul is the person stepping up to lead that work. We are still very early in the history of Ramp. Our current chapter is perhaps the most dynamic, but we have never been more optimistic on where it is going and the mission has never been more important. The businesses that trust us are navigating the same shift we are, and we intend to be there for all of it: managing their token spend, supercharging their finance teams, and helping them get more out of every dollar and hour. - Eric & Karim
