First off: you've got this! I'm sure lots of people on HN have felt this way (:hand-raised:) My approach is roughly: "getting out of my comfort zone" + repeat what worked and drop what doesn't. With a BIG caveat that this is all running off my own money, not investors. I get tempted by marketing/sales tools (eg: apollo.io, za-zu), vendor exhibitions, paid ads, etc but if I'm not fairly certain I'll get the $-spent back, I do the free/harder way first until I understand that system more. Dollars can give leverage, but aren't certain to. Also, publicly track the experiments you run as an accountability system (and doubles as a bit of marketing for your product) EG: Scroll down on 24HourHomepage.com to see a history of how I've thought about growing it roughly week over week
