$5 million isn't going to come anywhere near covering the cost to bring a mental health AI to market. The data center requirements are going to be very stringent (Healthcare level security compliance plus advanced AI processing), and then there will be regulatory hurdles, marketing, etc. Oh, and there isn't even an MVP application yet, so there's still a ton of development that will require outsourcing or significant hiring, or there won't be any chance of revenue for the next 5 - 10 years.
