Today, Long Lake completed our $6.3B acquisition of Amex GBT.
Long Lake acquires and transforms generational businesses with AI across the American services economy.
Amex GBT is the travel partner for 17,500 businesses in 140 countries. Last year, Amex GBT booked 35 million trips for 10 million travelers.
This marks Long Lake’s 40th acquisition, and our family of companies now employs nearly 30,000 people.
We founded Long Lake three years ago with the thesis that AI is going to change every company, but there’s a large overhang between AI capabilities and how most businesses leverage AI tools.
We partner with strong, profitable, and growing businesses to help them deploy AI and improve their customer service.
Our first cohort of companies has doubled their EBITDA in less than two years through topline and productivity growth, all while increasing headcount. (We’re proud to say that we’ve never conducted a layoff.)
We’re excited to share a bit more about what we’ve been up to.
the frontier just got more affordable.
we teamed up with @OpenAI: GPT-5.6 Sol is 50% off on router through September 18.
one endpoint, every model, each request routed to the best fit. so every AI dollar goes further.

suggested connectors in @tryramp Stack chat.
huge part of automating accounting work is accessing data in different systems. with new connectors shipping weekly, needed awareness when it's solving a problem.
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.
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.
“Build faster.” Yep, that about sums it up. We want @tryramp engineers to be as productive as possible, firing on all cylinders. Jolt is pushing us even further in that direction. High. Speed. Development. Velocity. That's the move here. Welcome Jolt team! ⚡️

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.
@scicomm // @hubermanlab
Cofounders @eglyman and @karimatiyeh launched @tryramp to build a more efficient generation of corporate cards.
The six-year-old startup just broke $1 billion in annualized revenue in August, and it now claims more than 45,000 businesses as customers. https://t.co/PRomrsNEP9
Exclusive: Ramp, a startup that uses artificial intelligence to automate corporate finance tasks, says it has raised $500 million in a funding round that values the company at $22.5 billion https://t.co/NjLsNaTOLO
Finance teams waste hours chasing receipts and answering weird policy questions. Now they don’t have to.
Introducing our first @tryramp AI agents. Upload your company policy and put the bullshit work on autopilot so your finance team can actually do finance.
I first met Calvin in 2016.
Karim and I had just launched Paribus. We weren’t a big company. Our office was my kitchen table.
So when an email from a 17-year-old high school dropout landed in my inbox asking for an internship, I skimmed by it. Thankfully, Karim didn’t!
- Admitted into MIT at age 16
- Code running on the International Space Station
- Top 20 in the country in the Putnam Math Competition
Calvin arrived on his first day in a T-shirt he wore representing the United States in a programming competition. Three weeks later he’d built an AI model to automate refund decisions. This was years before people knew what AI even was.
Fast forward four years. Karim and I start Ramp. Our first phone call? Persuading Calvin to join as a founding engineer.
The challenge: make filing an expense as easy as taking a photo of a receipt!
Fortunately, Calvin looks at hard problems the way a dog looks at a bone.
I watched him come back to the office every night, just as I was leaving, Wendy’s in hand, no small talk, working because he wanted to, only pausing to watch The Yankees’ playoff run.
Eighty thousand expenses a day are now submitted using the code he wrote. Each one takes just 15 seconds, not 15 minutes. That’s 20,000 hours of work saved every day!
Why am I telling this story?
I think founders get too much credit. The single most important thing we do is hire people smarter than us.
Phil Knight had Jeff Johnson, who drove to track meets across the Pacific Northwest and sold the first 3,250 pairs of Nike’s from the boot of his car. That’s why you’re wearing Nikes.
Steve Jobs had Ken Kocienda, who mapped thousands of thumb taps to solve the seemingly impossible problem of touch-typing on glass. That’s why you have an iPhone in your pocket.
Calvin is one of those people.
Who wouldn’t want him to file your expenses?
Our engineers have been building AI tools like CRAZY the past month — already saving the whole team hundreds of manual hours.
Our mission is to save businesses time & money. That drive for efficiency starts with our culture.
Here are some highlights 🧵
EXCLUSIVE: A car was found smashed by a giant yellow wrecking ball in Chinatown, NYC.
Foul play? Or elaborate marketing stunt to inform businesses they can earn more on their operating cash?
Our team investigates.

📣 Huge update — I’ve started a new company!
After 4 years at Ramp, I’ve started something new (and we're hiring). The past few years were incredible - being a part of the rocket ship on a ~15 person engineering team to an 1000+ person org, and growing from 100s of customers to 25,000+. The talent, ambition, and teamwork I experienced have set the bar for what greatness looks like—I’m excited to keep that standard into building this new team.
Much more to come on the new company soon — but here’s a preview: Ryan Daniels + I already working with our first partners, saving our customers millions of dollars in legal costs, and there’s a ton of demand to keep up with.
Long term: we’re tackling a massive vertical opportunity worth over $200B, leveraging AI to make a real impact.
We’re growing the early engineering team. If you’re passionate about transforming legal with AI, I’d love to connect! Referrals welcome too!
"The team you build is the company you build." @rabois and @bchesky are two of the best in the world at hiring. @tryramp, while much younger, is NYC's fastest growing startup in history and one of its most talent dense companies.
If you're free on October 17, we hope you'll join us for https://t.co/tCPoxDfF7m. @karimatiyeh and I will share Ramp's playbook on how we source, onboard and try to create the conditions for people to do their lives’ work
