Harvey CEO Winston Weinberg is flying high.

His legal AI startup has overcome skepticism — both from highly-trained lawyers who think his product can’t work, and AI lab maximalists who think it can just be copied by Anthropic or OpenAI — to now work 100,000 lawyers, generate about $200 million in revenue, and as of yesterday, reach an $11 billion valuation.

But on The Upstarts Podcast, Weinberg shares a never-before-told story about how in early 2024, he and co-founder Gabe Pereyra almost crashed long before that — all because they chased a “one-shot” way to hack their way to scale.

It’s an unusual Upstart Moment, but a fascinating one. The broad strokes: Harvey was valued at about $700 million at the time, and had the chance to combine with a more traditional player with 10x the employees, but about the same valuation. Its board was nervous about it, but Weinberg and Pereyra thought it would solve many of their problems: hiring, scaling, a customer base.

They decided to agree to the deal, then finance it, in what Weinberg calls a 1980s style financial gambit. But it didn’t work. Harvey would need to take on too much debt to make it happen; the company walked away.

“I remember we had a week of just being like, ‘What is the future of our company? And how do we build this?’” Weinberg recounts on the show. But it was a bullet dodged — and a hard-earned startup lesson, he adds — Harvey has opted against acquisitions since.

“It would’ve been a huge mistake,” he says. “ I think sometimes as a founder you have the sense of ‘Oh, there’s a quick, easy way to win this.’ And you learn over time that there isn’t, that doesn’t exist.”

You can hear more of that story, as well as how a cold email to Sam Altman helped launch Harvey’s journey; why he believes lawyers are a surprise power user of AI tools; and how he’s handling a challenge from Anthropic, in the full episode.
