I used google ads with very specific phrases and geolocation limited to rich countries. I spent a lot on it, the sales were like twice of what I spent, but I got some good contacts from it and they kept coming back for more.
But, and that’s a big “but”, I was employed before, noticed a niche that no commercial provider filled, and created my product. It wasn’t an idea that I thought was fun or could change the world.
I’m just sharing how I’ve found b2b contacts. My product was a financial failure but opened some doors.
