John Li

Respect the hustle of John Li, the dude’s the real deal in the startup world, no cap. He’s a YC S18 alum and the brain behind Vimcal, this super slick calendar app that’s actually changing the game for busy pros and remote teams. But his story? It’s way more than just another founder hitting a home run. It’s about grind, pivoting, and never settling.

So, John’s been around the block. Before jumping into startup life, he worked at Apple as an intern in engine dev, dude was coding at the big leagues early on. Then, he jumped into Peer, a company he co-founded, which got snapped up by Twitter. That’s where he really got the taste of what it’s like to build something that catches fire. At Twitter, he was a full-stack engineer, working on the kind of scale most of us only dream about. That experience? It’s like rocket fuel for his entrepreneurial engine.

But what’s wild is how he took all that high-level tech and turned it into something totally personal, a frustration with scheduling. Turns out, John and his co-founder were fundraising at the time and kept hitting walls with their calendar tools. Instead of bitching about it, they jumped into building Vimcal in 2018, and it’s been growing ever since. They started with the basic idea but then pivoted, like real founders do, into what Vimcal is today: a sleek, intuitive calendar for busy people. Recently, they even launched Vimcal EA, a version tailored just for executive assistants. Big names like Kleiner Perkins and Dropbox are already using it. That’s some serious traction.

What’s also dope? He’s raised $7 million in funding to keep pushing this thing forward. And his background? It’s a mix of tech, business, and languages, he’s got degrees from Berkeley in CS, biz, and French, and he speaks English, Mandarin, and French. Dude’s not just a coder; he’s a legit polyglot and a strategist.

What does all this say about him? It’s simple: John’s about fixing problems he cares about, not just building for the sake of it. He’s the kind of guy who’s been through the trenches, from Apple’s labs to startup hustle, then straight into the fire of fundraising and product-market fit. His process shows he’s relentless, adaptable, and knows how to turn frustration into innovation. He’s not afraid to pivot, learn, and go all-in on what he believes in.

Bottom line? John Li is the example of a tech founder who’s crushed it because he’s been in the game long enough to understand the grind, smart enough to pivot, and driven enough to build something that actually matters. He’s all about making tools that help people work better, and honestly, that’s what makes him one of the most interesting guys in the startup scene right now.
