Zeteo Gateway
Everything Zeteo has built, available inside your product.
Retrieval, citations, patient context, knowledge management, and the evaluation harness around them took us years to build. Gateway gives your team all of it behind one API. You ship in weeks and spend your engineering on what makes your product different.
Built by clinicians and AI engineers trained at Columbia, Johns Hopkins, Yale, Mount Sinai, Georgia Tech, UT Austin, and UT Knoxville, with experience across the VA, Epic, and Cerner, and an advisory bench of practicing specialists and health system leaders. HIPAA by design. SOC 2 certified. Your data stays under your control.
How Gateway works
One endpoint,
structured answers.
Send a message and its context and get back a cited, structured response with suggested follow-up questions.

Customer
What one team saved.
Urology Health built its patient-facing experience on Gateway rather than hiring its own AI and engineering team. Compared with the two to three hires that work would have required, the team estimated roughly a 9x cost savings and shipped within weeks.
