Tamarisc Ventures

John McManus, the founder and managing partner, leads all investment decisions. He brings a background in family real estate operations to the firm's thesis-driven approach. Day-to-day sourcing and diligence are conducted by a lean team, with McManus holding final say on commitments.

Tamarisc sources through a practitioner network of real estate owners, developers, and operators. These industry relationships generate both investment opportunities and strategic portfolio advantages, as many limited partners serve as pilot-site hosts and early-adopter customers for portfolio companies.

Tamarisc operates as a venture capital firm funded predominantly by a single family office. The structure blends family-office permanence with a disciplined early-stage venture process. Tamarisc does not market itself as a multi-family office or accept outside discretionary capital pools.

The firm concentrates on Seed and Series A rounds, with initial checks typically between $250,000 and $1.5 million. Tamarisc often leads or co-leads rounds and maintains pro-rata rights in follow-on financings. The firm has participated in later-stage rounds selectively through existing portfolio relationships.

Tamarisc avoids sectors disconnected from the built environment, including biotech, enterprise SaaS without a real estate or energy application, and consumer internet. The firm also does not invest in traditional real estate development projects or REIT structures, maintaining a pure technology-equity focus.

Tamarisc makes direct equity investments in operating companies and does not allocate to external venture funds. The firm has co-invested alongside institutional venture investors, including Clean Energy Ventures and Fifth Wall, but its capital is deployed exclusively through direct positions.

Tamarisc actively co-invests alongside climate-focused and PropTech-specialist venture firms. The firm values co-investment partnerships that bring additional industry relationships and follow-on capacity. Lead investors in shared rounds have included Clean Energy Ventures and Fifth Wall.
