Good thoughts here. Worth noting that Signal doesn't really gain anything from your Gmail data other than the ability to provide you network benefits via the relationship strengths implied by that data. And you don't need to connect your Gmail to use the service. You can sign in with email/password and use all the investor finding tools, which is arguably Signal's primary benefit right now. There isn't a great tool out there to find investors (and similarly, for investors to effectively broadcast what they do and do not want to see). That part isn't chicken and egg. You can use Crunchbase, AngelList, etc., but it's a slog. Signal should keep getting better in that regard.
