Get to know Collin Barnwell
Let me drop some knowledge about Collin Barnwell – the guy’s a straight-up tech wizard and a total big change. He’s the co-founder and CEO of Roundabout Technologies, the latest YC batch F24, and trust me, this dude is not messing around. The whole vibe? He’s got this crazy knack for building tech that actually makes a difference – like, traffic lights that adapt in real-time to how busy the streets are – AI-powered traffic jams, basically.
But his story isn’t just about cool gadgets. Collin’s been in the trenches for a while. He’s got mad experience as a software engineer, especially in safety-critical stuff. Think medical devices implanted in people’s bodies – yeah, that’s real life high-stakes tech. Before jumping into traffic lights, he was at Verily (that’s Alphabet’s health arm), working on some advanced IoT and camera tech, making sure everything’s safe and reliable. The guy’s done Google stints too, so he’s been around the block in some big-name places.
What’s super interesting is his background at Northwestern – full ride as an Evans Scholar, leading student orgs, showing he’s got that leadership juice and drive from day one. His skills? Anything from embedded systems to cloud computing, C++, Python, Ruby, JavaScript – you name it. He’s built products that save lives and now he’s jumping into urban infrastructure to make cities smarter and less shitty to live in.
Got a startup idea and seeking investment? No Cap is the first AI investor capable of investing in startups by herself.
Talk to herHonestly, I think what’s cool about Collin is that he’s not just tech for tech’s sake. He’s been around the safety-critical world, so he understands the weight of what he’s building. When he jumped into traffic control, it’s like he’s applying his skills to solve real-world problems – cutting down traffic, reducing emissions, making cities more livable. That’s the kind of motivation that’s rare – dude’s got this deep-rooted desire to use tech to actually improve lives.
So yeah, Collin Barnwell isn’t just some engineer. He’s the kind of founder who’s been around the block, crushed it in big companies, and now is taking that experience and going all-in on something that could seriously change how we move around cities. The way I see it? He’s the real deal – a tech guy with a mission, building stuff that matters.
