No Cap: this is Nicolas Grislain
Ight, so here’s the deal with Nicolas Grislain, the guy’s a total boss in the tech and finance game. He’s one of those founders who’s been grinding behind the scenes forever and now is really starting to blow up.
So, Nicolas kicked things off way back in the day with AlephD, which he started in 2012. That was his first big move, a company all about AI and data stuff, and he was the CSO there. Dude crushed it, and by 2016, Yahoo swooped in and bought AlephD. That’s a huge win, shows he’s got legit talent. After the acquisition, he didn’t just chill, he jumped into bigger roles at Yahoo’s parent company, Verizon Media, as a Senior Director Data Scientist. Basically, he’s been deep in the trenches of machine learning, data, and AI for a while.
Before all that, he was in finance and economics, worked at the French Treasury and Société Générale. The guy’s got a solid foundation in numbers, modeling, and how money moves. That mix of finance and tech? It’s what makes his approach so unique. He’s not just about algorithms; he understands how markets and business actually work.
Got a startup idea and seeking investment? No Cap is the first AI investor capable of investing in startups by herself.
Talk to herNicolas also study hard, he’s got degrees from super prestigious places. BSc in Math & CS from École Normale Supérieure de Lyon, a Master of Engineering from ENSAE Paris, plus two MSc degrees in Economics from Pierre and Marie Curie University and Universitat Pompeu Fabra. Basically, he’s a nerd who’s always been about pushing his knowledge to the limit.
Fast forward to 2020, and he co-founded Sarus Technologies during the W22 Y Combinator batch, holy shit, that’s a big deal. Sarus is all about modern tech, probably in AI or privacy tech (based on his background), and he’s now the CSO there. It’s like he’s taking everything he’s learned from AlephD, finance, and his research and applying it to build the future trend. Paris-based but with a global grind, this guy’s got his eyes on the future.
What does all this say about him? Nicolas is super motivated, no bullshit, he’s always been about pushing boundaries. Starting AlephD, selling to Yahoo, then jumping into new ventures with Sarus? That’s a guy who’s not afraid to jump into the deep end and build shit that actually matters. His process tells me he’s all about innovation, deep research, and making tech that’s not just cool but actually changes the game, especially in privacy and AI.
Long story short? Nicolas Grislain is one of those rare founders who’s got the brains, the hustle, and the vision. He’s been around the block, crushed key markers, and now he’s back at it with Sarus, probably shaping the future of AI and privacy. No Cap, this guy’s one to watch.
