Avalanche is an early-stage private investment firm led by Katelyn Donnelly. The firm backs technology companies at structural inflection points—markets where long-building forces are beginning to create significant and lasting change.

Avalanche invests selectively, often before broader consensus forms, and works closely with founders navigating complex markets. The firm pairs its capital with firsthand experience building and scaling companies across government, energy, critical infrastructure, and other highly regulated or operationally demanding industries. Avalanche maintains a concentrated portfolio and co-invests alongside a trusted network of firms and individuals.
