## Questions

### Who runs investment decisions at Reaction?

Reaction splits portfolio management across two fund teams. Enrico Carbone and Singari Seshadri serve as General Partners for W250 Venture, the firm's first fund. Charles Froland, Mike Dorsey, and Managing Partner Dan Matthies lead Catalyst Fund. All five listed investment principals are sourced directly from the firm's own team page, with no external senior hires disclosed. An advisory board chaired by Carlos Moreira provides strategic guidance across both vehicles.

### How does Reaction source deal flow?

Reaction sources nearly all of its portfolio from the Stanford University ecosystem, where its founding team met and where Fund I is named after a Stanford classroom ("W250"). The firm draws from Stanford's climate labs and health-tech research groups. Additionally, Reaction publishes its own original research — including the Green Inflation and Impact Currency frameworks — which functions as inbound marketing to mission-aligned founders before formal fundraising processes begin.

### How is the Catalyst Fund different from W250 Venture?

W250 Venture was Reaction's first fund and pursues a broad mandate across health technology, climate innovation, and enterprise tech. The Catalyst Fund, managed by Charles Froland, Mike Dorsey, and Dan Matthies, focuses more tightly on climate innovations, with the stated thesis of scaling top Stanford climate technologies to the industries they can decarbonize. The separation allows the firm to allocate dedicated capital to climate while maintaining a multi-sector early-stage vehicle.
