It's been sometime since I was there, but it felt like it tried to be a South Park Commons style salon, but promising founders in the Software and Hardware space had plenty of better options like Engine or I-Labs, or moving out West to join YC or SPC.

I've noticed UAV/Autonomous/SpaceTech (UAE and Saudi are on a buying streak rn) and Biotech (unsurprising) startups do fairly well in the Boston scene.
