Problem

Simbie AI addresses the administrative and follow-up gaps that cause patients to fall out of care and burden healthcare practices with repetitive manual work. The company says 30% of return visits do not happen because patients get lost in logistics such as scheduling tests, starting new medications, or understanding next steps; this costs doctors 10% of revenue. Practices also spend heavily on staff to chase patients manually, while scheduling, reminders, intake, and routine questions contribute to burnout, errors, delays, and frustrated patients. The central use case is closing the loop after a diagnosis, medication change, or ordered test so that the patient ultimately reaches the next appointment.

Product / Service

Simbie provides clinically intelligent, EHR-integrated AI agents that communicate with patients and providers through voice and text. The agents proactively contact patients at high-risk follow-up points, answer questions, coordinate sequential outreach, manage scheduling and refills, and document the interaction directly in the medical chart until the request is resolved and the patient is handed off to a return visit. Its broader AI medical-staff offering also covers registration, pre-visit intake, patient education, inbound and outbound calls, chart documentation, and refill workflows.

The product is customized to a practice's existing systems and workflows rather than delivered as a generic chatbot. Simbie says it can receive and place calls to patients, providers, and pharmacies, integrates with systems including Epic and PerfectServe, and charges based on utilization. The intended benefit is 24/7 patient access and follow-up capacity without proportionally expanding the front desk, with the company advertising savings of up to 60% and more time for human staff to focus on patient care.

Market

Simbie competes in healthcare-native voice AI, AI medical receptionist, patient-access automation, and clinical workflow automation. Its closest positioning is the practice and care-team layer of the market: automating patient communications and follow-up while writing activity back to the EHR. Adjacent competitors include Hyro and Commure for health-system and patient-access automation, Hippocratic AI and Sully AI for clinical-grade voice workflows, and Infinitus and Notable Health for administrative or broader healthcare automation. Simbie's differentiator is its emphasis on making sure patients complete the logistics between visits, rather than only answering inbound calls.

The company is active and appears to have paying or operational deployments rather than being merely pre-revenue, although no revenue figure is disclosed in the available sources. Its YC profile says it launched in January 2025, grew 400x, is used around the clock in practices across the country, reports 0% churn and entirely inbound growth, and lists the company as active. Simbie was founded in 2023 and reportedly raised a $5 million round in June 2026; PitchBook reports $5.5 million raised in total, with Neotribe Ventures, FoundersX Ventures, and Y Combinator among its investors.
