Who is Jimmy Young
Yo, you gotta hear about Jimmy Young. This guy’s a straight-up big change. So, he’s from Sydney, Australia – grew up there, probably dreaming big, then jumped into the US scene, got his BA and JD, and somehow, that led him into the startup world. No joke, he’s now part of YC’s S21 batch, which is no small feat. That’s where the real deal founders hang out.
Jimmy’s all about moving fast and thinking big. He’s been around some heavy hitters – worked at Lyft, Twitch, and most recently, he was a product lead at DoorDash for DashPass and their affordability stuff. Basically, he’s been deep in the delivery and marketplace system, understanding what makes these platforms tick. That’s key, because it shows he’s not just a random founder – he’s someone who’s been in the trenches, figuring out how to make delivery faster, cheaper, better.
Then, he took all that experience and jumped into his own thing with Cache. This was his shot to shake things up – an online convenience store fulfilled by tiny, automated dark stores. Think of it like a secret weapon for ultra-fast shopping, delivered by DoorDash or UberEats. Super slick idea. Sadly, Cache is on pause now, but no cap, it was a bold move. It shows Jimmy’s not afraid to try wild concepts, push the boundaries of what’s possible.

Talk to herWhat really stands out is his process – he’s someone who’s always been connected to the hustle. From Sydney to Silicon Valley, he’s seen how the delivery game works, learned what customers want, and then jumped in with both feet to build something new. That speaks to his motivation – he’s not just in it for the fame or money. He genuinely wants to solve problems, make life easier, and push the tech frontier.
In a way, Jimmy’s story is about not settling. He’s a guy who’s crushed it in big companies, then decided to run his own show. He’s the kind of founder who’s got the technical chops, the hustle, and the guts to try shit that most people wouldn’t even think of. And even if Cache is paused now, he’s the type who’ll jump into the future trend – no bullshit, no hesitation.
Bottom line: Jimmy Young is one of those guys who’s been around the block, learned how marketplaces and delivery work from the inside out, and then used that to build something fresh. He’s got that entrepreneurial fire, the kind that makes you think he’s just getting started. Keep an eye on him – he’s got the possible to do some real damage.
