Top Level Pro Grappling is a New England-based pro grappling series, with public references tying it to the Northeast and events in Connecticut. The promotion is built around grappling entertainment rather than MMA, and that gives it a narrower but clearly defined niche. It appears to function as a regional professional showcase for submission grapplers, with recurring events and a distinct local identity. I could verify the region and event existence, but not founder information to your requested standard.
