Basata Raises $21 Million Series A for AI Medical Referral Automation

Basata raised a $21 million Series A round led by Lan Xuezhao of Basis Set Ventures. Cowboy Ventures participated in the round, as did Victoria Treyger through her firm Sofeon, which made its first investment. 5 million in total funding.

Founded two years ago in Phoenix, Basata automates the gap between primary care referrals and specialist appointments. When a referral arrives, typically by fax, the system reads the document, extracts clinical information and deploys an AI voice agent to call the patient directly to schedule an appointment.

Patients can also reach an AI agent at any hour for questions or tasks such as prescription renewals.

Kaled Alhanafi is the CEO and co-founder of Basata. Chetan Patel is the president and co-founder. Vivin Paliath is the CTO and third co-founder. Alhanafi previously worked as an executive at Lyft and Cruise.

Patel spent a decade building cardiac devices at Medtronic. The company integrates with the electronic medical record systems used by specific medical specialties. Basata initially focused on cardiology then expanded to urology.

It recently turned down a large deal in a specialty it had not yet mapped thoroughly. Basata has processed referrals for roughly 500,000 patients to date. Approximately 100,000 patient referrals were processed in the last month alone.

Its revenue model is usage-based, with practices paying per document processed and per call handled. Seventy percent of Basata’s new deals now come through word of mouth, Alhanafi said. The founders argue their differentiation lies in combining document processing and voice agents into a single end-to-end workflow tailored to specific specialties.

The administrative burden between primary care and specialists remains substantial. Specialty practices often receive hundreds or thousands of documents monthly, most by fax, and struggle with small teams. Alhanafi described his father’s experience after a serious carotid artery diagnosis, when he was referred to three cardiology groups.

Only one called back within a couple of weeks. Another responded after surgery was already completed. The third still has not called. Patel experienced parallel delays when his wife fainted on a flight with their young children.

Even with his cardiology expertise and knowledge of relevant devices, navigating the administrative process took far longer than it should have. “We have the best doctors, we have some of the best medicines, but the care gap is just so wide,” he said. The competitive landscape includes Tennr, founded in 2021 in New York.

Tennr has raised over $160 million to date and is valued at $605 million. Assort Health last year raised funding at a $750 million valuation. Aileen Lee is the founder of Cowboy Ventures. Victoria Treyger is a former general partner at Felicis Ventures.

Lan Xuezhao began her career as a PhD researcher modeling the human brain before working in corporate strategy at McKinsey and Dropbox. Lee said the founders’ years of experience matter when selling to medical practices. “There are a lot of [VCs] chasing around high school dropouts and college dropouts, but when you’re selling to medical practices, trust is a really big deal,” she said.

For now the administrative staff Basata works with are more worried about drowning in volume than about displacement, the founders said. Administrative workers often have decades of experience and know the work intimately, yet the volume exceeds what any reasonable number of hires could absorb. Basata’s pitch is that freeing them from repetitive tasks makes them better at the rest.
