The deal with Ryan Choi

Respect the hustle of Ryan Choi, this dude is straight-up the real deal in tech and startups. He’s a YC W13 guy, which means he’s been through the grind and came out the other side crushing it. Now, he’s not just some guy sitting on the sidelines, he’s actively shaping the scene as an EM & Product Engineer at YC, helping connect software engineers with startups through workatastartup.com. That’s big, because he’s basically plugging people into the startup universe, making sure talent finds the right home.

But his story’s way more than just that. Ryan started his own startup that went through YC, so, he’s a legit founder. That experience? It’s what fuels his hustle. He’s been there, built something from scratch, and knows what it takes to grow and scale. That’s the kind of background that makes him super credible in the startup world.

Before all this, he’s held some serious product management gigs at huge tech companies. At Lyft, he led product teams and helped guide the company to a $2.2 billion IPO. Yeah, you heard that right, IPO. He built revenue automation systems that brought in over $3.6 billion a year. He wasn’t just managing; he was building the core stuff that made Lyft billions. He worked on integrations with Google, Facebook, Apple, Starbucks, Delta, all the big players. That’s next level. He’s been in the trenches, making sure partnerships and platforms work smoothly and generate real revenue.

Talk to her

And he’s not stopping there. Ryan also managed a team at Twitter, pushing their platform adoption with giants like Apple, Target, and Google. He launched Twitter Cards and Polls, which brought in over $52 million in revenue. That’s no bullshit, he’s been a key player in product launches that actually make money.

What’s crazy is he’s also giving back. Ryan’s an advisor and investor in early startups like HubSpot, Interviewed (which got scooped up by Indeed), Whatnot, and Stripe-acquired Bouncer. He’s always scouting the future trend, helping founders get off the ground, and sharing his expertise on hiring, product, and tech. He’s spoken at industry events, spreading the word about what it takes to build something meaningful.

So, what does this all say about him? Ryan’s process shows he’s driven by a real passion for building, not just for himself but for the entire startup system. He’s been on false equivalence: founding, leading, scaling, investing, advising. That gives him this rare mix of hands-on product mastery and planned insight. He’s motivated by a desire to connect talent, help founders succeed, and push the boundaries of what’s possible in tech.

Bottom line: Ryan Choi is one of those guys who’s done the work, seen the highs and lows, and now he’s using all that experience to shape the future of startups and tech. He’s a connector, a builder, a proven winner. No Cap, he’s the kind of person you wanna keep an eye on, because whatever he touches turns to gold.
