One of the owners. We are a small family business. When things get busy more of the family helps out. Some years ago we were an AgLeader dealer so we had an office in town. Now we just make the NTRIP client so we work from the family farm. 
We made our prior Windows software all "freeware", for those old enough to remember what that meant.

I'm the only one currently doing any firmware or software work currently. Though everyone can help out doing PCB assembly when needed.
