Jake Sussman
Jake Sussman is the cofounder and CEO of Marble Health, a virtual behavioral health company that embeds inside American schools to get anxious, depressed and overwhelmed kids into group therapy within days rather than months. He helped build Headway into a mental-health unicorn, then walked away to teach fifth-grade English at a Brooklyn charter school, where one overstretched counselor for hundreds of students convinced him the youth side of the system was broken. In 2023 he founded Marble with fellow Headway alum Dan Ross, betting that insurance-funded virtual group therapy, routed through school counselors, could scale care without waitlists. By late 2025 Marble had run more than 15,000 sessions and raised a $15.5M Series A led by Costanoa Ventures.
