Will Ventures

Will Ventures is an early-stage venture capital firm investing in category-defining businesses across sports, entertainment, and consumer industries. Co-founded in 2019 by former Harvard football teammates Brian Reilly and Isaiah Kacyvenski (also a former NFL linebacker), the firm is headquartered in Boston, Massachusetts, with an additional office in Los Angeles. The firm takes a hands-on, research-backed approach, maintaining an exclusive partnership with OneTeam Partners — which manages marketing and licensing rights for over 4,000 professional athletes — giving portfolio companies access to athlete-driven marketing and promotion. Its focus spans sports, health, fitness, media, and consumer technology, using sports as a proving ground for innovations with broader consumer applications in areas like connected fitness, wearables, gaming, and immersive media. Portfolio companies include Liteboxer, Jock MKT, Just Women's Sports, Candy Digital, Mighty Health, and Elo Health. The firm typically invests at seed and Series A, with an average round size around $8 million, deliberately keeping its portfolio to a disciplined 20 to 25 companies rather than spreading capital thin. Will Ventures has raised $215 million in assets under management across two funds — a $55 million Fund I (2019) and a $150 million Fund II (2022) — both oversubscribed and backed by university endowments, professional sports team owners, and entrepreneurs. Its approach favors low-volume, high-conviction bets paired with deep founder engagement and active portfolio support.
