Fortify Ventures

Fortify Ventures is an early-stage venture capital fund founded in June 2011 by Jonathon Perrelli, based in the Washington DC and Northern Virginia area. The firm invests in technology that improves human performance — products that help people feel better, function better, and perform better. Investment themes include metabolic health, sleep, stress, recovery, fertility, home health, brain performance, mental health, and breakthrough supplements with clinical backing, with a preference toward differentiated hardware and consumer health products anchored in the physical world. The firm explicitly avoids biotech, pharma, and medical devices. General Partners Adam Fazackerley, Simon Rakoff, and Eli Kia work alongside Perrelli. Fortify writes $100,000 to $2 million first checks, entering post-product but pre-product-market fit, typically at pre-seed or seed stages. The fund has made over 41 investments and achieved more than 10 successful exits over 15 years. Fund II began deploying GP capital in December 2024. Notable portfolio companies include ID.me, the identity verification unicorn; Hinge, the dating app acquired by Match Group; Social Tables, the event seating platform acquired by Cvent; and Fleksy, a keyboard app that was also acquired. More recent investments include Somble, Samphire Neuroscience, Different Health, and Alter, an AI infrastructure company. Fortify also organizes Distilled Intelligence, a major startup showcase event. DI 3.0 was held in Loudoun County, Virginia in October 2025, bringing together 100 startups and more than $1 million in funding commitments. This community-building orientation reflects the firm's broader thesis: that founders in human performance technology benefit from an ecosystem of operators, scientists, and investors who deeply understand the sector's unique regulatory and commercial challenges.
