Jake Xia earned his PhD at MIT, then spent 17 years at Morgan Stanley running trading and risk across New York, London, and Tokyo. In 2013, Harvard Management Company made him Chief Risk Officer, putting him in charge of risk for the largest university endowment in the world.

Was going to Stanford worth it? Depends who you ask. Balaji Srinivasan (@balajis) Earned his PhD at Stanford and taught there before becoming Coinbase's CTO and a general partner at a16z. Worth it for him, he says, but he wouldn't tell you to go today: the pipeline to Silicon Valley is breaking. Ask him where he'd go instead → delphi.ai/balajis Celeste Amadon (@Celesteamadon) Met her co-founder at Admit Weekend, then dropped out to build Known, an AI dating app that's raised nearly $10 million. She says she couldn't have built it anywhere else: the people were the point, not the academics. Ask her when it's worth leaving → delphi.ai/celeste-amadon Dr. Elisa Song (@healthykidsl737) trained at Stanford, NYU, and UCSF and has spent 25 years as an integrative pediatrician, with a national bestseller on kids' health. Her answer: the credential was worth it, but her most valuable insights came from sitting with families, not a classroom. Ask her what the degree didn't teach her → delphi.ai/drelisasong Val Whiting Won two national championships playing basketball at Stanford and left as the conference's all-time leading scorer. She says the game gave her skill, but the real gift was the standard: everything there ran at championship level. Ask her what to look for in a school → delphi.ai/val-whiting Whatever question you're weighing right now, someone has already lived it. Ask them on Delphi.

On Delphi, every profile is built on the lived experience of a real expert. Before you trust someone with what matters, you can explore how they actually think.

In 2003, a 19-year-old co-created a piece of software and gave it away for free. It was WordPress, and today it powers over 40% of the web. Matt Mullenweg (@photomatt) turned that idea into Automattic, the company behind WordPress, Tumblr, and WooCommerce, now past $500M in revenue. Along the way he's backed 100+ startups and spent two decades defending the open web. You can ask the father of WordPress anything. His digital mind is live: delphi.ai/photomatt
