It’s hard to imagine a better use for AI than @EvidenceOpen. Daniel Nadler and his world-class team at OpenEvidence are building what I believe will become an AI-era treasure—a life-saving resource for doctors, patients, and their families. I can’t imagine the future without it.

@EvidenceOpen is an ‘N of 1’ company by almost any definition. Brilliant team. Life-saving product (literally) used daily. Viral organic growth (40% of all US doctors). It’s a privilege to get to work with startups like these.

Thanks @ilyaf and @kleinerperkins for their awesome KP Fellows program and shout out to the ones interning at @harvey__ai: Skylar Wang, @Jat1nn, Elaine Zhai, @ASundresh, and Yihan Huang!

Honored to be part of the @windsurf_ai journey. Can’t wait to see what @_mohansolo, Douglas, and team accomplish next! 🚀

So enjoyed our conversation @jaltma, especially drawing on the lessons from past technology cycles to the current AI super-cycle. Thank you, Jack!

I'm co-hosting a poker game next Tuesday night in SF with a very fast-growing, exciting startup - if you're an engineer open to new roles, DM me! We have a few spots left.

Bay Area X — we are hosting an ambitious group of builders and engineers. Renting out Spin in SF on the evening of July 10th. DM if interested. No normies.

Hosted a pitch day for 4 early stage companies in SF a few weeks ago with 8VC (@Jimmy_S_Yun), Kleiner Perkins (@LM_Braswell), DST Global and Contrarian Thinking. Captured the afternoon to share. We will be hosting these in SF, LA and NYC throughout the year. Join us!

Alexandr Wang: “Hire people who give a shit” The ScaleAI founder is asked for the best advice he has for founders, to which he responds: “The biggest thing is you have to really, really care.” Alex explains this is also the number one trait he looks for in people he hires: “When you interview and interact with people, you can tell who phones it in and whose work is so incredibly important to them that it eats at them if they don’t do great work. One of the greatest indicators of how much I enjoyed working with people and how successful they were at Scale was just the degree to which their soul is invested in the work they do.” It’s important that the CEO lives this principle too. “I still review every hire at the company,” Alex says. “I care immensely. I work with all these people who care immensely. And that lets us feel much more deeply what happens in the business, so we learn more quickly and adapt more quickly, and I think that’s been quite important to the success that we’ve had.” One of Scale AI’s values is that “quality is fractal.” “High standards trickle down within an organization,” Alex explains. “Most of the time when people realize their manager or their manager’s manager doesn’t really care, that removes the desire for them to care. So it’s incredibly important that high standards and care for quality is a deeply embedded tenet of the entire organization.” Video source: @ycombinator (2025)
