Mattan Griffel

I'm Mattan, Co-Founder & CEO of Y Combinator-backed One Month, the "For Dummies" of online education. I created One Month Rails, the #1 bestselling Ruby on Rails online training course for teaching beginners how to build web applications. I'm also the NYC Ambassador to the Sandbox Network, a collection of young leaders under 30.

I teach and advise on growth hacking, online education, and learning to code. I've advised companies like Pepsico, Bloomberg, GM, NYSE, and JPMorgan, spoken at New York University, Cooper Union, The School of Visual Arts, Parsons at The New School for Design, Singularity University, The Downtown Project, First Round Capital and Social Media Week, and have been featured in Forbes, BusinessWeek, MIT Technology Review, Huffington Post, Mashable and The Next Web.

I studied Philosophy and Finance at New York University and wrote my thesis on the metaphysics of consciousness.
