He was eventually hired by Redis-the-company, allowed them to use the trademark (originally they were Redis Labs which was a compromise with him), went to their conferences, trained their Redis developers (who contributed to Redis-the-open-source), etc.. I assume he was happy with the deal as he spoke positively about them and chose to spend a lot of time with them, and eventually retired after I presume getting a nice amount of money from the decade-long adventure.
