The lowdown on Rohan Das
Bet, let me tell you something about Rohan Das. This guy is the real deal, straight up. He’s part of YC W24, which already says a lot. The dude’s been crushing it in the tech world for a minute. Before jumping into startup land, he was a staff engineer and manager at Google-like, top-tier, building the YouTube homepage to handle billions of requests a day. That’s no joke. The guy’s been in the trenches, making sure giant-scale products actually work. He’s known for being super sharp in engineering, AI, and designing products that actually make sense – elegant, practical, expandable stuff.
Then, in 2023, he co-founded Decipher AI with Michael Rosenfield. This isn’t some random project-these guys are both ex-Google, used to handling the big leagues, and now they’re building AI tools to analyze session replays and runtime data. Basically, they help companies understand what their users are doing, find bugs, and get real insights to make their products better. It’s like giving companies a crystal ball into user behavior, powered by AI. That’s some next-gen shit, and it’s clear Rohan’s passion is building solutions that actually matter, not just bullshit tech for the sake of it.
What’s dope is, his whole process screams one thing: he’s obsessed with making things work at scale and actually helping people along the way. From managing billions of requests at Google to creating AI that turbocharges startups’ products-that’s a huge leap, but it’s all connected. He’s not just in tech for tech’s sake; he’s about having an effect. He’s out here solving real problems and jumping into the deep end without hesitation.

Talk to herRohan’s story is about the hustle, the drive to build practical, expandable tech that moves the needle. He’s the guy who’s always been in the trenches, figuring out how to make the impossible work, and now he’s taking that know-how to startups through Decipher AI. He’s based in the US now, and he joined BEAMSTART in Feb 2025, so he’s clearly all in on this new chapter.
Bottom line? Rohan Das is the kind of founder who’s been there, done that, and is now shaping the future of AI-powered product insights. He’s got the experience, the passion, and the skills to change the game. No Cap.
