We used Signal to set up almost half of our investor interactions. The system makes sure we came in with a 'warm' introduction from a friend which greatly improved the odds of a favorable outcome.
This is making every interaction between VC and founder way more meaningful.
Our company used Signal religiously during our (successful) seed raise and it's hard to estimate how much time and hassle it saved us.
It would be great (as a start) if we could connect this to multiple email addresses as many people have multiple nowadays. It would also be great if you could specify "sweet spots"/investing ranges in multiple ways. Many people in venture invest both out of a fund and personally (angel) or have access to SPV vehicles for certain size deals and a fund for others. Pretty cool product otherwise.
I can search for VCs by sector, create target lists, edit information, see my connections, and much more!
