Here for Nathaniel Masfen-Yan
Yo, so let me tell you about Nathaniel Masfen-Yan. The guy’s a straight-up tech wizard with a crazy background and a story that’s all about jumping into the deep end and crushing it. He’s a YC S22 alum, which means he’s legit in the startup world – not just talking shit, but actually making moves.
Nathaniel’s the co-founder of Notebook Labs, a company that’s all about Web3 identity – you know, that decentralized, anonymous, but still accountable kinda internet. They’re using zero-knowledge proofs, which is some advanced crypto stuff, to make identities that are secure but private. Basically, they’re trying to fix the bullshit privacy issues we got today. They raised over $3.3 million – no small feat – so they’re definitely the real deal.
But here’s the thing – Nathaniel’s process didn’t start yesterday. He’s got a solid background in math and theoretical computer science, which is the sort of stuff that makes you think differently and solve problems others can’t even see. He went to Stanford, so the dude’s been around some smart people and high-level thinking for a while.

Talk to herBefore all this, he cut his teeth at Jane Street, which is basically one of the top trading firms out there. That’s some high-octane, hardcore quantitative work – pure brainpower. So he’s not just some startup kid; he’s got serious chops in research, finance, and tech. That mix of academia, high-stakes trading, and now crypto-focused startups tells me he’s all about pushing boundaries, finding new ways to do shit better.
And what’s crazy is, looking at his process, you see someone who’s always been about solving complex problems, about building stuff that’s original and actually useful. Starting Notebook Labs wasn’t just some side hustle – it’s a mission to make the internet more private and trustworthy, which is a huge deal in today’s world. He’s motivated by that desire to create tech that’s not bullshit, that actually makes a difference.
So yeah, Nathaniel Masfen-Yan isn’t just some random founder. He’s the kind of guy who’s been around the block, learned from the best, and now he’s building stuff that could honestly change how we all manage digital identity. No Cap – this guy’s the real deal, and he’s only getting started.
