Access leaders at ambulatory groups and health systems often compare Luma Health and Relatient to cut no-shows and let patients book online. Both send reminders and two-way texts tied to the EHR schedule, offer self-scheduling, and now sell AI voice agents. Luma Health, based in San Francisco, built its product around filling empty slots from waitlists and serves more than 1,000 health systems after buying Tonic Health in 2025. Relatient, based in Atlanta, sells Dash, a scheduling engine that applies the same provider rules to online booking, the call center, and voice AI, and its Dash Self tool was Best in KLAS for patient self-scheduling in 2024.

Luma Health is for an access team that lives on fill rate and wants waitlists, reminders, AI call handling, and fax automation from one vendor that works with many EHRs. Relatient is for a group whose biggest problem is booking the right visit with the right provider, and that wants the same scheduling rules behind online booking, the call center, and voice AI.
Walk away from both if you are a solo practice happy with your EHR's built-in reminders. Walk away from Relatient if you will not spend the time mapping locations and provider templates before go-live. Walk away from Luma Health if intake forms and payment capture are your main need.
