MCJ Collective writes first institutional checks where the founder + early product matter more than traction. The seed market is the most dispersed segment of venture; matching to thesis (sector, stage, geography) is where most cold outreach succeeds or fails. VC Boom tracks MCJ Collective alongside 47,000+ other active investors, ranked weekly by recent-deal momentum, sector concentration, and partner activity.
Drop your pitch. VC Boom scores it on the 8 dimensions VCs read for and ranks the 47,000+ active investors in the database by fit. MCJ Collective is one of them, and we'll tell you exactly where they sit in your top 100.
