Seabury Capital Management closed $3.0 billion in initial commitments for MBV Investments LP, with the Al Mazroui Group writing $2.5 billion as anchor investor. The allocation is among the largest single-LP checks into a U.S. crossover fund since TPG Growth's 2021 vintage.
The structure is crossover equity with exposure to late-stage private companies and public secondaries, according to market participants familiar with the mandate. Al Mazroui, a UAE-based family office and industrial conglomerate, now controls 83 percent of the fund's initial capital base. Seabury declined to disclose the cap or whether it will accept additional commitments past first close. The timeline from formation to initial close was 11 months, faster than the 18-month median for funds over $1.0 billion in 2025.
The anchor commitment reflects a broader pivot by Gulf allocators into U.S. growth equity as public equity volatility has narrowed spreads between late-stage privates and small-cap public comps. Al Mazroui's allocation mirrors moves by Abu Dhabi's Mubadala and Qatar Investment Authority, both of which raised crossover allocations by 22 percent and 19 percent respectively in the first half of 2025. The $2.5 billion check is also the largest known Gulf commitment to a non-infrastructure U.S. fund since Saudi Arabia's PIF allocated $3.0 billion to Vista Equity's 2023 flagship.
Seabury has not disclosed sector exposure, but the firm's prior portfolio skews toward SaaS, fintech, and logistics technology. The fund's legal structure as an LP rather than a commingled vehicle suggests tax and governance customization for the anchor, a setup increasingly common when a single LP holds north of 75 percent of a fund. Seabury manages approximately $8.0 billion across separate accounts and commingled vehicles, making MBV Investments its largest single fund to date.
Operators should track Seabury's deployment pace through Q4 2025 and whether the firm announces a hard cap or remains open for follow-on commitments. If the fund deploys at the crossover median of 24 months, expect $1.2 billion in notional capital to hit growth-stage balance sheets before mid-2026. Allocators should also watch for co-investment rights bundled into the Al Mazroui anchor terms, which would indicate the group is building direct late-stage exposure alongside the fund.
The close arrives as crossover funds have raised $47 billion year-to-date, outpacing infrastructure by $11 billion for the first time since 2021.
