It's kinda the same for me, our product solved a problem that was not enough annoying to people for them to consider buying it, so we never had the product market fit, and never managed to sell a single license. The company still exists today, but it's mainly surviving with us doing freelance work and hoping one of our side project might generate some revenue. Maybe as open-source, the product could have some success, but I don't know how to "sell" open-source or make a revenue from it.
