Shut up and take my money!
The demo led to multiple interested customers, now we just had to build the product. Bootstrapping mornings, nights, and weekends, TrackJS launched into beta in October of 2013. Our first customers graciously helped work out scale issues as we built the infrastructure to handle error volumes from the world's biggest sites.
We publicly launched our service in March of 2014 with lots of interest from developers and the media. Today, TrackJS is profitable and fully sustainable, so you can trust that we'll be around for awhile. TrackJS remains bootstrapped and wholly-owned by the working partners.
