Defy.vc

Co-founders Neil Sequeira and Trae Vassallo serve as managing directors and are the firm's primary decision-makers. Sequeira previously spent over a decade as a general partner at General Catalyst, while Vassallo was a partner at Kleiner Perkins, where she led early investments in Nest and other hardware-enabled software companies. The partnership structure concentrates investment authority with the two co-founders rather than distributing it across a large investment committee.

Defy.vc focuses on pre-seed and seed-stage companies, typically leading or co-leading rounds. The firm writes initial checks that public transaction records place in the $500,000 to $2 million range, with significant reserves held for follow-on investments through Series A and beyond. This concentrated approach is designed to provide portfolio companies with sustained capital access and consistent board representation as they scale.

The firm invests in enterprise software, industrial technology, AI and machine learning applications, digital health, energy transition, and mobility. Defy's thesis centers on applying software and data infrastructure to large, physical-world industries — logistics, manufacturing, energy, and security — where technology penetration historically lagged behind consumer internet and pure SaaS markets.

Yes. While the firm is headquartered in Woodside, California, its portfolio includes companies operating in South Asia and other international markets. Chaldal, a Bangladesh-based grocery logistics platform and one of Defy's publicly known portfolio companies, illustrates the firm's willingness to back founders building in large domestic markets with distinct regulatory and infrastructure dynamics.

Defy is structured as an operator-led venture firm rather than a finance-first one. Both co-founders had substantial operating and board experience — Vassallo with Nest through its Google acquisition and Sequeira across numerous enterprise software boards at General Catalyst — before founding the firm. The resulting model emphasizes a concentrated portfolio, hands-on board work, and sector specialization in areas where the partners have direct domain expertise.
