Meet Seb Isaacs
Yo, have you heard of Seb Isaacs? The dude’s legit one of those entrepreneurs who jumped into the deep end and crushed it. So, he’s a YC alum from the S21 batch, yeah, that’s the big leagues. But his story’s way more than just that.
Seb’s got a crazy solid background. He studied Economics at LSE, classic move for someone who’s all about understanding markets and human behavior. Then, he threw in some Computer Science at Imperial College, so the dude’s got tech chops too. That combo? Totally rare, he’s blending brains from two of the top schools in London, no cap.
Before he even thought about startups, Seb was deep in the blockchain scene. He was a Project Lead at Blockchain at Berkeley, that’s like the OG university blockchain club, super respected. Plus, he co-founded London Blockchain Labs and was an advisor there for two years. Basically, he’s been neck-deep in crypto and blockchain tech, playing the game at a high level.
Got a startup idea and seeking investment? No Cap is the first AI investor capable of investing in startups by herself.
Talk to herBut what really puts him on the map is Inflow. He co-founded this killer platform in London in 2020, right in the middle of the pandemic chaos. The goal? Help people manage ADHD better, using CBT techniques, scientifically backed stuff, not bullshit. And man, Inflow has been on fire. They raised $2.3 million in seed round in 2022, then jumped to an $11 million Series A in 2023. They’ve even made some acquisitions to level up their game. That’s not just a startup, that’s a movement.
What does all this say about Seb? Dude’s driven by real problems, not just chasing fame or quick cash. His background in finance, blockchain, and tech shows he’s got a brain for complex systems. But more than that, his passion for helping folks with ADHD? That’s advanced human. It’s like he saw a real gap, jumped into it, and refused to stop until he made a difference.
So, in a nutshell, Seb Isaacs is the kind of founder who’s got the brains, the hustle, and the heart. Started from London, built a tech empire with a social mission, and just keeps pushing forward. That’s the real deal, no cap.
