Boomerang

Boomerang is the warm-intro orchestration layer for B2B sales teams. We turn your team's network, your customers, your investors and board, and your advisors into a measurable pipeline channel. Most B2B sales motions broke between 2022 and 2026. Cold email reply rates fell 70 percent at the senior buyer altitude. AI SDR volume produced brand damage at scale. Senior buyers built defensive infrastructure that does not distinguish between thoughtful outreach and spam. The signal layers (6sense, ZoomInfo, Apollo, Demandbase) still work. The activation layer they fire into stopped converting.
