Kleiner Perkins’s Leigh Marie Braswell learned about risk from playing poker: “If the odds are in your favor, you push your chips to the center”

Braswell grew up in rural Alabama, and wasn’t introduced to poker until she was an undergrad at MIT. And it wasn’t until she was an intern at Jane Street, the famed quantitative trading firm, that she was hooked on the game.

“We didn’t go out and party in New York—we stayed in and played poker,” said Braswell. “So, that’s how I really learned by playing every day against people at Jane Street.”

Braswell immediately joined the MIT Poker Club, where she reunited with Alexandr Wang, who she’d first met at a competitive math competition in her junior year of high school. Braswell went on to be an early employee at Scale AI, at the time knowing nothing about venture capital. 

“I barely knew what VC as a concept was,” she remembers. “Alex told me ‘oh, we’re signing a Series A term sheet.’ And then I went off and Googled: ‘What’s a Series A term sheet?’”

Braswell, now a partner at Kleiner Perkins, may be an unlikely VC, but her path to venture was built slowly and then all at once. She started angel investing in 2020, her last year at Scale: Her first check was into Ambience Healthcare, now valued at $1.1 billion. After more than two years at Founders Fund, Braswell joined Kleiner, a legendary firm in the midst of a turnaround led by Mamoon Hamid and Ilya Fushman. I spent more than six months getting to know the team at Kleiner, including Braswell, to tell the story of that turnaround (a 3,600-word feature published this past weekend). And Braswell repeatedly came up as someone who’s a rising star, not just at Kleiner, but in VC. 

Why? It’s simple: Braswell has been a key investor behind some of the buzziest AI deals that materialized in 2025. At Kleiner, she backed Windsurf (an Alphabet acquihire) and Neon (acquired by Databricks), and her Founders Fund deal to back Chronosphere ultimately saw the company acquired by Palo Alto Networks. (Yes, 2025 was a big year for Braswell, who’s been in VC for six years if you squint, an industry where often people are successful with one or two real exits after a decade.)

Braswell—whose current Kleiner portfolio includes Nooks, Convoke, Reevo, Avoca, and Forge—doesn’t exactly consider herself an AI investor, though. 

“I do describe myself as relatively generalist,” she said. “However… you definitely want to have unfair advantages, or pools of certain people and networks that you’re really in. And when you look at those networks of people—especially these days and with good reason—that’s ideally in and around AI.”

Braswell had started hosting regular poker nights with Wang while she was at Scale, and she still does—over time, they’ve become a piece of her investing strategy. It’s a recurring way to source deals, build founder relationships, and help portfolio companies hire. But it’s also a mindset. 

Because in the end, poker’s about tracking probabilities and making decisions with incomplete information, much like early-stage investing. And though there may be things you can’t know, you can know your odds. 

“The core lesson from poker,” said Braswell, “and it’s something I’m grateful for as a VC: If the odds are in your favor, you push your chips to the center.”
