Voyager Ventures

Sierra Peterson and Sarah Sclarsic, the firm's founding partners, lead all investment decisions. Both have backgrounds spanning climate policy, technology deployment, and science-driven investing. The firm has not publicized additional investment committee members, so the partnership appears to operate as the principal decision-making body.

Voyager invests at pre-seed and seed stages, providing first institutional capital to climate technology companies. The firm does not publicly participate in growth equity or late-stage rounds. This early focus means Voyager's portfolio companies are typically pre-revenue or early-commercialization science and engineering projects.

Voyager exclusively makes direct equity investments into early-stage climate technology companies. The firm has not indicated any fund-of-funds activity or commitment programs into other venture capital managers. Its capital is deployed company by company, typically through standard venture rounds.

The firm sources through the founders' longstanding networks in climate policy, academic research, and technology ecosystems. Sierra Peterson's prior work in climate finance and Sarah Sclarsic's operating and science background give Voyager access to university labs, climate accelerators, and policy circles where early decarbonization technologies emerge.

Voyager will not invest in companies whose core business models depend on fossil fuel extraction, production, or unabated combustion. The firm also avoids climate-adjacent software that lacks a measurable emissions-reduction pathway — it favors hardware, biotech, and deep-science interventions.
