Root Causes
Joon Care was a Seattle-based virtual mental-health platform focused on teens and young adults, founded in 2019 and led by CEO Amy Mezulis, a clinical psychologist. It raised roughly $13M. In 2025 the company was acquired by Handspring Health, another youth-focused virtual mental-health provider, in what industry sources described as a soft-landing acqui-hire rather than a strategic exit. The founding team joined Handspring. The youth mental-health tele-health category, briefly hot in 2020-2021, has consolidated aggressively as payer economics squeezed out sub-scale players.
