Alex Grinman

Hi there! I'm Alex.

I work at the intersection of product design, engineering, security and cryptographic identity.

I co-founded krypt.co to make strong authentication easy and beautiful to use for consumers and developers. We're the makers of Krypton Authenticator and ApproveAPI.com. I focused mostly on product design, ux, and ios/back-end engineering, but worked on everything ranging from front-end web to the design of our cryptographic protocols.

I spent about 5.5 years at MIT. I finished my undergrad in 2015 in and my masters in 2016 in computer science + cryptography. I had the privilege of working with Shafi Goldwasser on my master's thesis, Natural Language Processing on Encrypted Patient Data.

I've also recently built a few other things.

  • OneTimeDrop is an encrypted file-sharing service that's simple & secure.
  • Sift is an iOS Network Sniffer.

I've been making iOS apps for 9+ years -- starting with iOS 3 back when I was in high-school! I built a number of real-time transportation apps with my dad to help commuters in Boston, most recently Greenline.
