Frequently asked questions
Who runs investment decisions at MaSa Partners?
Max Duckworth is the central investment decision-maker today. He co-founded the firm with Sarah Godlewski, who left day-to-day operations in 2018 to serve as Wisconsin State Treasurer. Duckworth’s background combines executive roles at a Fortune 500 energy company with earlier academic work in particle physics and environmental policy, and he personally guides the firm’s 4P diligence process.
How does MaSa Partners source its deals?
Sourcing runs heavily through the personal networks of Max Duckworth and Sarah Godlewski. Duckworth’s board roles — including his honorary position at Halcyon, a social-entrepreneur incubator — provide direct access to mission-driven founders. The firm also cites collaboration with co-investors and stakeholders as a sourcing channel, but it does not maintain a disclosed institutional origination engine.
What is MaSa Partners' known posture on co-investments alongside external GPs?
MaSa actively welcomes co-investors. Its website invites visitors to "co-invest in our portfolio companies," though the firm does not act as a fund manager. This posture allows external parties to participate alongside MaSa on a deal-by-deal basis, effectively creating an informal syndication model around its early-stage impact positions.
