Hello, creator here. Do you guys have any suggestions on how to make this product successful? I am trying to sell this service to businesses, in order to offer it to their employees, but it has not been successful so far. Should I write an API? I am also trying to sell it as white-label software. I think there are many cases where such a simple tool can help millions of people doing carpooling efficiently, but struggling to get it in the hands of people, even not making much money.
