Just as a warning, angel.co is completely useless if you don't already have a number of preexisting connections to the angel investing community. If you start with 0 followers, you will have 0 followers forever, and nobody will ever see your profile.
This may not be entirely true. I started on angel.co as a beginning investor with no deal flow. I have invested once via angel.co so far and have come close several times. I have also made several connections which have now allowed my deal flow to expand well beyond angel.co. A 30K deal would be ideal for a beginning angel or syndicate.
