What Simperium will eventually offer is an easy-to-use platform for building apps that sync. I’m happy to announce that I’m now an advisor to and a (very minor) investor in Simperium. I haven’t worked on sync systems, but I am hoping that I can provide some insight to the Simperium team on building a developer platform and scaling out their backend systems.

If you’re a Simplenote user, expect the app to get better and better. If you’re developing an app that needs to sync, Simperium is building a platform you’ll want to use. If you rely on apps that sync, you’ll be using Simperium-powered tools before you know it. Fred, Mike, and their team are up to great things, and I feel privileged to be able to support them as best I can as they take their company to the next level.

This is great news for a great service.
