Find the One Open DM Channel a Hard-to-Reach Person Left Unlocked

Find the One Open DM Channel a Hard-to-Reach Person Left Unlocked is a cold outreach tactic for getting your first users: After a cold email went unanswered, a LinkedIn request was ignored, and Twitter DMs were closed, the founder noticed the target's Instagram DMs were open and messaged there, getting a reply the next day that led to a deal.

It's a strong fit for teams of almost any kind, and works especially well for founders chasing a specific gatekeeper or investor. As a cold outreach play, plan for low effort and expect results to show up quickly, all grounded in 1 linked primary source.
