I'm going to focus on the "no one knows you" bit since I don't know anything about the industry/vertical you're in.

Step 1 -- The first thing to do is to build some social proof. I hope you already have a few customers. Request them to be references for your product and feature them and their feedback on your front page

Step 2 -- Ask your customers about who else in their network they think could benefit from such a product and reach out to them.

Step 3 -- As you sign on more customers, repeat Step 1 + 2

Step 4 -- Figure out if there is a pattern in your customers and try to truly understand the market they exist in.

Step 5 -- Once you understand the market, try to figure out which channels through which you can best reach that market (e.g. google ads, billboards, tv ads, partners, etc.). Of course, word of mouth is the best bet, but there are often other really lucrative channels too.

Iterate. This is just the beginning!
