Mark Patricof is no longer asking athletes to show up for photo shoots. He is handing them term sheets, allocation memos, and carry percentages—then watching them wire seven figures into early-stage consumer companies. Patricof Ventures, the former Athlete Ventures rebranded last year, has quietly shifted from celebrity endorsement broker to full venture platform in which the athlete is investor, operator, and brand architect. The firm now manages roughly $500 million across three funds, with athletes including Patrick Mahomes, Naomi Osaka, and Kevin Durant sitting in partner seats, not ambassador chairs.
The operational difference is blunt. Traditional endorsement deals pay an athlete a flat fee or royalty to attach their name to a product they may never use. Patricof's model requires the athlete to commit capital—often $250,000 to $2 million per deal—and participate in diligence calls, product development sessions, and board observer roles. In exchange, they receive equity and carry on fund returns, the same economics available to institutional LPs. Mahomes, for instance, co-led a $15 million Series A into athletic recovery brand Momentous in late 2022, participating in pricing negotiations and customer acquisition strategy. Osaka did the same with plant-based nutrition company Nuun, wiring $1.8 million and joining quarterly strategy reviews. The athlete becomes allocator, not billboard.
This repositioning matters because it solves a credibility problem that has plagued athlete-brand partnerships for two decades. Consumers, particularly Gen Z cohorts, dismiss endorsement deals as transactional noise. But when an athlete writes a check from their family office and sits on a cap table next to Sequoia or Andreessen Horowitz, the signal changes. The brand gains distribution through the athlete's social channels—Mahomes alone commands 36 million Instagram followers—but it also gains operational leverage. Patricof's portfolio companies report that athlete co-investors open doors to retail buyers, media partnerships, and sponsorship deals that institutional VCs cannot. When Durant joined a $12 million round for hydration brand Liquid I.V. in 2020, the company secured a Whole Foods national rollout within 90 days. The athlete's cultural currency becomes balance-sheet currency.
The economics are also reshaping how family offices and high-net-worth athletes think about capital deployment. Patricof structures his funds so that athlete LPs contribute 10 to 15 percent of total fund capital, with the remainder coming from institutional investors and corporate LPs such as Nike and PepsiCo. The athlete LPs receive 20 percent carry on fund returns, the same split as Patricof himself, and participate in quarterly allocation meetings. This is not a side hustle. Mahomes, according to a person familiar with his portfolio, has deployed roughly $18 million across Patricof funds since 2021, targeting a 25 percent IRR over a seven-year horizon. Osaka's family office has committed $22 million across two funds, with a focus on female-founded consumer brands. The athletes are building diversified portfolios with venture-grade returns, not collecting appearance fees that depreciate with their playing careers.
The risk, of course, is that most venture funds do not return 25 percent. Patricof's 2019 debut fund, Athlete Ventures I, posted a 1.2x multiple as of Q4 2023, respectable but not exceptional. Several portfolio companies—including a direct-to-consumer sneaker brand and a fitness app—failed to secure follow-on funding and shut down. Athletes accustomed to guaranteed contracts and signing bonuses now face J-curve drawdowns and illiquid capital. One West Coast family-office allocator, speaking on background, noted that several athlete LPs grew impatient with the three-to-five-year capital lockup and requested early liquidity, which Patricof declined. The model requires financial sophistication that not every athlete possesses, regardless of their on-field earnings.
Patricof is now scaling. The firm closed a $180 million Fund III in March 2024, with 14 athlete LPs contributing capital and six holding formal partner titles. The fund will target 20 to 25 early-stage consumer brands over the next 18 months, with check sizes ranging from $5 million to $12 million. Patricof is also building out a talent advisory arm, staffed by former CAA and WME agents, to help athletes structure their venture allocations and negotiate co-investment rights in third-party deals. The firm is effectively becoming a family office for athletes who want to deploy capital, not just earn it.
The industry is watching. Several institutional VCs, including Andreessen Horowitz and Kleiner Perkins, have quietly approached Patricof about co-investment opportunities, recognizing that athlete networks unlock consumer distribution faster than traditional growth marketing. Meanwhile, rival athlete-investment platforms—such as Durant's Thirty Five Ventures and Serena Williams's Serena Ventures—are adopting similar structures, converting their athletes from limited partners into general partners with full carry rights. The shift is structural, not cosmetic.
What to watch: Patricof will announce three to five new portfolio companies by mid-Q2 2025, likely in the athletic apparel, recovery tech, and plant-based nutrition categories. Several athlete LPs are negotiating co-GP roles for Fund IV, expected to launch in early 2026. And at least two institutional LPs are reportedly conducting diligence on the platform, sizing anchor commitments north of $50 million. The model is no longer experimental.
The closing fact is this: Mahomes's venture portfolio, managed through Patricof and his family office, now represents roughly 12 percent of his total net worth—more than his equity in the Kansas City Chiefs organization. The athlete is no longer just playing the game. He is capitalizing it.
The takeaway
Patricof Ventures has converted elite athletes into co-investors with carry rights and **$250K-$2M** commitments, rewiring endorsement economics into venture returns.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
