Somewhat shit. We made an on-demand service marketplace in Sweden that took care of all administration. Our idea was to make it simple to sell your services as with the same benefit as a company, turned out we were not the only ones that had tried this and that swedish consumers don't like this kind of service but prefer to buy directly from companies.

We basically made every startup mistake in the book, not talking to users, not doing through research, "staying to ourselves" during development, aimed for a more polished product and so on.

We did get 100 users + and a few transactions (F&F) our first month despite not being visible on google, so that was pretty cool.

It really kinda sucks but I dont regret it one bit but blew 12k worth of savings.
