David Blitzer’s 154 Partners closes $400m debut fund

154 Partners has closed its first fund at $400 million, reaching its hard cap a little over a year after launch. The firm was founded by former Blackstone Tactical Opportunities executives Isaac Harrouche and Mike Berlin, with David Blitzer on the investment committee. Backed by Bolt Ventures and strategic family offices, 154 is targeting businesses built and led by founders, family owners and experienced operators at the lower end of the middle market. Its focus includes sports and live event services, alongside residential and business services, with target companies typically generating $2 million to $20 million in EBITDA and equity checks of roughly $40 million to $100 million per platform. 154 has also pointed to guest-services businesses in sports and live events as an early area of activity.

This points to a different part of the sports economy from the one that usually grabs attention. Rather than chasing clubs, leagues or media-rights assets, 154 is targeting the businesses that sit around live sport and help it function at scale. That includes service categories where markets are often fragmented, operational improvements can be meaningful and growth can be built through consolidation and better execution. In that context, the fund offers a clearer view of where private equity is increasingly finding value in sport: not only in the assets on the pitch, but in the infrastructure that supports the wider industry
