154 Partners has closed its debut private equity fund at $400m, reaching its hard cap as investor appetite persists for lower mid-market strategies.

The firm, backed by Blackstone veteran David Blitzer, is targeting smaller businesses across sports, live events, residential services, and business services, with a particular focus on companies supporting the sports ecosystem.

Founded by former Blackstone Tactical Opportunities professionals Isaac Harrouche and Mike Berlin, 154 Partners is positioning itself in a segment where competition is less intense and operational value creation can be more pronounced. Their strategy focuses on founder- and operator-led businesses generating between $2m and $20m in EBITDA, offering a pipeline of scalable assets within fragmented markets.

“Some of the most compelling opportunities exist at the smaller end of the market, especially in the sports and live events sector,” David Blitzer said in a company statement.

For investors, the fund provides exposure to niche segments tied to sports infrastructure, including event services and operational support businesses, rather than direct ownership of teams.

The successful raise comes despite a challenging fundraising backdrop. Global private equity fundraising declined 16% in 2025 to $395bn, marking a fourth consecutive year of contraction.

Consequently, 154 Partners’ ability to reach its hard cap underscores continued investor confidence in specialised strategies, particularly at the smaller end of the market where entry valuations and growth potential remain attractive.
