DreamBox Learning

The Bellevue, Washington adaptive-math company that a Netflix founder bought to power charter-school "learning labs". It became one of the best-known K-8 supplemental math programs in US schools, passed through three rounds of financial ownership (Reed Hastings and the Charter School Growth Fund, TPG's Rise Fund, then Elliott's Evergreen Coast Capital) and was folded into Clearlake-backed Discovery Education in 2023.
