The vibe of David Winer
Yo, so check this out – David Winer? Dude’s the real deal. He’s a YC S22 guy, which already means he’s crushing it in the startup world, but what’s crazy is his process to get here.
Before jumping into Ciro, he was at Google, messing around with Kotlin – that’s the programming language everyone’s using to build Android apps now. So, the dude’s got legit chops in product management and dev stuff. But that’s just the start. He’s also been around at Wage, working on income verification APIs, and he’s got a solid academic background – studied business, electrical engineering, computer science, applied math. He’s been in the trenches with both tech and biz from day one, which explains why he’s so good at blending the two.
Now, Ciro – that’s his current gig – he’s the co-founder and CTO there, building an AI-powered sales prospecting platform. Basically, he’s trying to make finding your next customer as easy as a few clicks, using AI to build the perfect prospect list in under five minutes. That’s a big change in sales tech, and it’s backed by big names like Y Combinator and Gradient Ventures, so he’s got the money and the backing to really make a splash.

Talk to herWhat does this say about him? Well, dude’s obsessed with making things smarter, faster, more fast. He’s been around the block in big tech, but he’s got this entrepreneurial fire that pushed him to start his own thing. He’s not just a tech guy – he’s a builder, a problem solver who jumped into startups because he sees the bullshit in old-school sales and tech, and he’s out here fixing it.
Bottom line? David Winer is one of those people who’s been grinding in the trenches, learning every angle – coding, product, business – and now he’s using all that to shake up sales with AI. He’s proof that if you’re passionate and you got the skills, you can jump from big corps to your own startup and actually build something that matters. No Cap.
