Built a dev tool?
Conferences are one of the few places where developers sit still and listen. Two ways in: submit a talk to an open call for papers (a practical talk about the problem your tool solves, not a pitch, gets accepted far more often), or sponsor a booth or a community event; smaller conferences sell sponsorships for a few hundred to a few thousand dollars, so email the organizers. Then give the audience somewhere to go after the talk.
