Will Ventures

Co-founders Brian Reilly and Isaiah Kacyvenski serve as managing partners and lead the investment committee. Reilly, a former Harvard football captain, and Kacyvenski, a former NFL linebacker, built the firm's strategy around athlete-sourced deal flow. Both partners actively participate in sourcing and diligence. The firm maintains a flat partnership structure concentrated in Boston.

Will Ventures sources deals through its athlete network — a community of professional and former collegiate athletes who identify startups building products relevant to sports, fitness, and human performance. This network functions as both a deal-referral system and a diligence resource. The firm's general partners, themselves former athletes, access locker-room and training-facility relationships that conventional venture firms cannot easily replicate.

Will Ventures makes direct early-stage and seed investments in portfolio companies. The firm does not publicly market a fund-of-funds strategy or participate materially as a limited partner in other venture vehicles, focusing its capital on primary equity rounds in sports-adjacent technology startups.

Will Ventures' athlete relationships operate informally as a sourcing and diligence network rather than a structured advisory program. The firm does not disclose a standardized compensation or equity-sharing mechanism for athlete referrals. The co-founders' own athletic backgrounds at Harvard and in the NFL underpin the network's credibility and operational cadence.
