## 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.
