Did you have any initial investment before YC? or what was the value? I don't get it. You started to make the service and pivoted multiple times... how big was

Did you have any initial investment before YC? or what was the value? I don't get it. You started to make the service and pivoted multiple times... how big was your team of programmers/designers once you were accepted ? Did you get money instantly ? ps. I'm looking for a one angel investor about 70k for my next app and don't know where to start looking. Already have few national apps making revenue and multiple made for customers, but nothing like this international one..
