Check out David Hsu

Yo, so here’s the deal with David Hsu, this guy’s a total rockstar in the startup world. He’s the founder and CEO of Retool, which is basically the go-to low-code platform for building internal tools. Launched in 2017, it’s now valued over 3 billion bucks, used by giants like Disney, Airbnb, Amazon, and even Mercedes. No joke. That’s some serious scale.

But here’s the kicker, David’s story isn’t just about throwing up a cool tech and riding the wave. It’s about grind, failure, and then crushing it by learning from his missteps. Before Retool, he tried his hand at something called Cashew. It didn’t work out. Failures like that suck, right? But David didn’t let it wreck him. Instead, he took that pain, and somehow turned it into fuel. He realized that the real problem was all the repetitive, boring coding that tech teams hate, and that’s where Retool came from. He saw an inefficiency and jumped into fixing it with a fresh approach.

Growing up in Silicon Valley, he got a pretty unique combo, studied philosophy AND computer science at Oxford. Yeah, dude’s got brains. But more than that, he’s got the startup hustle. He jumped into YC’s W17 batch, a tough crowd, but he and his team crushed it, landing $1.5 million in funding. That’s no small feat, especially considering they faced early setbacks. But they kept pushing, and before they even officially launched, they hit $2 million ARR and scored big enterprise clients, Disney, Airbnb, DoorDash, you name it.
