Comparing Hyro and Retell AI? Both are AI Agents & Chatbots and Voice & Phone AI tools in the directory, which is why buyers put them on the same shortlist. Below is a side-by-side look at how they price, what they integrate with, and when each is the better fit, so you can pick on the facts rather than either vendor's own sales page.

Hyro builds AI agents for healthcare, aimed at the call centers and websites of hospitals and health systems. Its voice and chat agents run over phone, web, SMS, and mobile apps and handle patient facing drudgery: scheduling and rescheduling appointments, prescription refills, MyChart troubleshooting, billing questions, and call routing, with escalation to humans when needed. Deep EHR integration, especially with Epic, is the differentiator, letting agents complete tasks end to end instead of reading FAQs aloud. In June 2026 it launched Care Intelligence, an analytics layer that turns millions of agent conversations into patient access insights for operations teams.
Israel Krush and Rom Cohen founded Hyro in 2018 during their final semester at Cornell Tech, and Weill Cornell Medicine became both first customer and investor. The company now serves around 45 large healthcare organizations, including Intermountain Health, Baptist Health, Hackensack Meridian Health, and Bon Secours Mercy Health. It has raised $95 million in total, most recently a $45 million growth round in October 2025 led by Healthier Capital, the fund of former One Medical CEO Amir Dan Rubin, with Norwest and Define Ventures participating. A May 2026 Five9 partnership cut contact center integration to about an hour.
Hyro does not publish pricing. Contracts are custom, scoped to call volume, channels, and integration depth, and its own 2026 benchmark report frames value in ROI terms, claiming deep EHR integrations unlock over $1 million in returns. Expect an enterprise sales process with security and HIPAA review, not a signup page.
Choose Hyro if you are a health system, especially an Epic shop, drowning in patient access calls, and you want a vendor that lives entirely in healthcare, speaks HIPAA natively, and plugs into your existing contact center stack. If you are outside healthcare it is simply not for you, and small clinics without real call center volume will struggle to justify the enterprise motion.

Retell AI is a platform for building AI phone agents that answer and place calls. You compose an agent from interchangeable parts: a speech-to-text layer, your choice of LLM, a voice from providers like ElevenLabs, and telephony via Twilio, Vonage, Telnyx, or your own SIP trunk. The platform handles the hard real time bits, interruption handling, latency, call transfer, and IVR navigation, and adds testing, monitoring, and post call analysis aimed squarely at contact center and front desk workloads.
The company came out of Y Combinator's Winter 2024 batch, founded in 2023, with Evie Wang among the cofounders. It grew unusually fast for a seed stage company: a $4.6 million seed led by Alt Capital in September 2024 arrived alongside a reported $3 million in annual revenue within months of launch. Named customers include telehealth company Ro, plus BPOs and contact center operators.
Pricing is published and usage based, which is refreshingly rare. Retell quotes $0.07 to $0.31 per minute all in, depending on your voice and model choices, with components itemized: text-to-speech from $0.015 per minute, LLM costs from $0.003 to $0.16 per minute, US telephony around $0.015 per minute. Every account includes 20 concurrent calls, extra concurrency is $8 per line monthly, phone numbers cost $2 monthly, and new accounts get $10 in free credits. Enterprise plans with dedicated infrastructure are custom.
Choose Retell if you have some technical ability, want a working phone agent this week, and value published per minute economics you can model before committing. Its contact center tilt (batch calling, warm transfer, IVR traversal) makes it a natural fit for support lines. Look elsewhere if you want a fully managed enterprise deployment with a vendor doing the tuning, or a pure no-code experience for a non-technical team.
