I contracted (development work) for a YC startup for over a year. About a month ago, they went radio silent after I decided to end my contract with them and pursue other work. I'm now owed about $8,000 for my final two invoices (which apparently was "on the way" via ACH and must have been retroactively cancelled once I told them those would be my final invoices).
They are not answering my calls or emails. I still have access to all of their code and deployment environments (which I have not touched), and they haven't worked with anyone else since my departure. I believe they're going under.
What are my options? Unfortunately, I am in NYC and they're in SF, and our contract provides for all disagreements to be settled in SF court.
Throwaway account because disparagement, NDA and all that.
EDIT: For everyone that thinks I have ideas about doing something malicious to their site, of course I'm not stupid enough to do that. I mentioned the access to code to show how I'm sure they're going under (I know they haven't had any active development since I left).
It's worth noting that you can insure yourself for unpaid invoices, at which point should this situation occur again, you tell the insurer, they pay you, and they will then do all the nasty legal stuff they need to to cover their loss - and you don't have to worry about it.
Not much help for this time around, but if you're working with fly-by-night outfits, it's a must.
Above all, don't do anything malicious, as you could then find yourself on the end of a criminal CFAA case, which would probably mean years in jail.
