Leif Welch named his company after a music startup that failed inside a year, and he kept the name through the rebuild anyway, because the idea sitting underneath it, connecting buyers and sellers with more transparency than either of them was used to, had always been the part worth keeping. The first Jamloop was a marketplace for musicians to find new and used gear, with a social network for local players attached to it.

Jamloop is now a platform for brands and their agencies to advertise on streaming television. Welch describes it as a Facebook or Google Ads style platform for the connected TV world, with an analytics layer that tracks store visits, website visits, purchases, and whether the campaign earned a real return on ad spend.

Recorded on the eTail Boston floor ahead of his keynote, Welch previews the argument he is taking to the stage. Search and social are demand-capture channels running into saturation, and television has always been the thing that creates demand in the first place. He splits AI into two jobs, creative versioning and platform-level campaign operations, and closes with the 70-30 blueprint Jamloop is putting in front of advertisers now.

Guest: Leif Welch, Founder and CEO, Jamloop
Recorded live at eTail Boston, August 10 through 12, 2026.
