Sounds like you are in a good position. This is not legal advice so go seek your own licensed legal counsel. If they don’t pay you the equity then they would not own your tech. Any revenue/profit they derive would be unjust enrichment. Not to say that I’d even leave them with working tech. I’d disable everything I built today until we had a more equitable agreement. No chance I’d let them profit from this tech alone anymore. At best I’d offer them a license to use it. Then go start your own company with it and be the majority owner. No need for the bad business partner.
