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!
