And you were right we did not have plan before launch, we wanted to build something that bring us excitement. and we are planing more about the future, since the project took off
FYI we still both have full time job
Obviously I can't speak about excitement but if you're worried about cost, you might want to research aws grant or things like that.
In 2019 my company invest in a startup, while doing IT due diligence I found out they get $100K AWS grant to be used for 2 years. Fyi this company business is writing articles about baby and almost no revenue at that time.
