Ever heard of Joshua Ying

Yo, you gotta hear about Joshua Ying. This guy’s the real deal in the startup world. He’s a YC W23 batch co-founder, which ya know, already says a lot. But what’s super sick is what he’s building – Sage AI. Think about it: a self-generating, self-maintaining code knowledge base for dev teams. Basically, he’s trying to cut out all that bullshit friction devs face when onboarding or trying to find info. That’s some advanced stuff, right?

Before jumping into all that, Josh was grinding at big names like Google, Squarespace, and even hitting up Johns Hopkins and Cornell. So dude’s not just talking tech – he’s lived it, worked it, crushed it. That background gives him mad cred to tackle complex problems in AI and software automation.

He’s based out in California, bouncing between San Jose and LA, but his work’s global. And he’s the real deal-not just about Sage, but also co-founded TomBot, which is all about AI-powered social selling solutions. Basically, he’s obsessed with making AI do the hard work, whether that’s for code or sales.

Talk to her

What’s wild is his process – from top-tier universities to giants like Google, then jumping into startups and now leading one that’s backed by YC. It’s clear he’s super motivated to fix real pain points in tech – knowledge friction, onboarding headaches – with AI. He’s not just in it for the hype; he’s building tools that actually make a difference.

Bottom line: Joshua Ying is that rare blend of deep tech experience and startup hustle. He saw a problem, jumped into it, and is now building the future of how dev teams work. No Cap, he’s a guy to watch – the kind of founder who’s not just playing around, but actually changing the game.
