After a few months we finally launched BuildGrowth: a filterable database of investors. You may say there are a few options in the market, and you're absolutelly right.
Other options we found lack of some features we need:
We're trying to solve a problem without create a new one, so we thought: if we mass contact investors through transactional emails, they'll probably report us. So, mass contact investors is simple: you pick a few investors, write a title, a description and request a revision from us (BuildGrowth). If we approve, we'll manually talk to every investor you picked, start a conversation and then present your message.
With this, we hope the response rate is bigger than any other platforms you use for automation. Using this strategy also avoid us to be flagged as spam.
This is our 'killer feature', we hope it's useful for anyone who purchase a lifetime license with us.
Ps: if you purchase a lifetime license and says you found us here in IndieHackers, we give you 1 free credit to try this feature and mass contact up to 50 investors at once.
Another thing we're aiming right now is to create a way to reach bigger audiences without paying for ads since our product monetization is a lifetime license, so we're basically planing this for the next weeks:
Paid ads isn't in our plans right now. I'll monthly report my growth here in IndieHackers so we can discuss more.
