1) If you were a W2 employee, and your concern is only getting paid, then call him in the morning and say, "Have a check for $15,000.00 dated today by 2 pm or I will file a complaint with OLS." https://olsconnect.microsoftcrmportals.com/employee-inquiry/ https://olsconnect.microsoftcrmportals.com/employee-inquiry/ If he doesn't pay you, then you and your co-workers can fill in that form with the "wage theft" option and the state will investigate for free. And they are relentless. You're also eligible for unemployment, and when you file, the state will also check what forms and payments he made. There are severe penalties for skipping that, and the state doesn't like holding the bag on UI. They will go looking for employers that do that. 2) If you're a contractor, then likely all you can do is to have a lawyer write a demand payment letter, and also state that you retain copyright on anything you wrote and weren't paid for. Every time there's PR (press, funding rounds, etc.), mail him (and the board, if any) a copy of the letter. But move on with your life otherwise. Lawyers typically start billing in the range of $20,000 for anything beyond a letter in large cities. If you sign any contract with a lawyer, add a "not to exceed" clause with what you can afford to spend or it will cost more than the wage theft. IANAL, but I've done my own legal paperwork, filings and representation for two decades. It's a handy skill.
