If your product is B2B I highly suggest creating a targeted outbound campaign. You can do it all on a super cheap budget too. You can setup a G Suite/Gmail account for $5 a month and use a tool like Mailshake for under $20 a month and you have a few different options for getting data/emails! Tell me more about your product and Ill jump on a free call to give you some more strategy/direction.

There's several ways to go about this. I personally suggest Upstack.co if you're looking for elite developers and have a decent budget in place. We also offer a 2 week trial to make sure the developer is a good fit!
