No Cap: this is Jason Tan

Yo, let me tell you about Jason Tan. This guy’s the real deal in the startup world. Dude’s been grinding since way back, jumping into big companies like The Boeing Company and then swinging over to startups. He’s got that tech hustle in his blood.

So, he co-founded Sift (used to be Sift Science) back in 2011 after hitting up Y Combinator’s summer batch. Yeah, YC S11, that’s where he really started to make waves. The goal? Building something that actually makes the internet safer. And he crushed it. Sift became a leader in digital trust and safety, using crazy-large scale machine learning to stop online fraud and abuse for some of the biggest brands out there, DoorDash, Twitter, Wayfair, you name it. Under his leadership, they were processing over 70 billion events a month. That’s some advanced shit.

What’s cool is that Jason’s not just about tech for tech’s sake. He’s super passionate about making products that matter, building teams that vibe, and constantly learning. Like, he genuinely believes in pushing himself and his crew to do better every day. That’s probably why Sift raised over $100 million from top investors like Andreessen Horowitz and Union Square, these guys saw the vision and knew he was the real deal.

Talk to her

Before all this, he cut his teeth at Zillow, BuzzLabs, Optify, even a stint at Boeing. Gives you a sense of his range, big enterprise experience mixed with startup hustle. Basically, he’s been around the block and knows what it takes to build something effective from scratch.

Fast forward to early 2021, Jason stepped back from being CEO and shifted to being the Executive Chairman. Now he’s all about the bigger picture, long-term vision, making sure Sift stays sustainable, and continuing to push the boundaries of what’s possible.

Bottom line? Jason Tan is one of those founders who’s not just in it for the quick win. He’s driven by a mission to make the internet safer, and his process shows he’s all about building something that lasts, that actually makes a difference. The guy’s a tech builder, a leader, and a true believer in continuous growth. No Cap, he’s one of those people you see changing the game, and he’s only just getting started.
