For the past two springs, a great program has run in NYC called the FinTech Innovation Lab. It's an accelerator program of a different sort. They accept a half dozen innovative financial technology companies into a twelve week program where the companies get direct access to top executives in the leading financial services companies in NYC. This program is all about validating your product or service with top customers. I have talked to entrepreneurs who have been through this program and I have heard universally that the access was incredible and the feedback was invaluable.
You don't have to be two entrepreneurs in a loft to be a good candidate for this program. You can be a two or three year old startup with a large team. What's important is the need for product market validation. If you have started a fintech company and have built a product or service and want direct access to the top customers in the market, this program may be for you.
