One concrete suggestion I would make is to watch Steli Efti's presentation on sales made to YC. It's filled with great info about how to qualify, follow up, pitch and in general, close sales. Steli is a master at that and maybe watching this will help you understand where things fell apart in your case. It's hard to say where it went wrong but I'm guessing with this info, you may be able to identify it better:
