About SiPhox Health
SiPhox Health is a hardware-first health-tech company. Backed by Y Combinator, Intel, and Khosla Ventures, we've spent four years building the hardware for at-home blood diagnostics. In October 2022, we put it into customers' hands: a B2C and B2B2C platform that pairs mail-in biomarker testing with wearables data to deliver personalized health insights.
Among direct-to-consumer diagnostics and DaaS (Diagnostics as a Service) companies, we're the only one that builds its own blood-testing hardware. That vertical integration is why the same silicon-photonics platform behind SiPhox at-home testing is what partners get access to through the API these docs describe.

Each kit ships to your customer, gets registered to them, travels to the lab, and comes back as a report. That journey is what the kit lifecycle describes, and every stage of it emits a webhook your integration can react to.
Our mission
SiPhox Health exists to extend human health span:
- Deploy a consumer blood-testing platform that brings lab-quality results home.
- Build the ecosystem around it that makes healthcare data-driven.
- Democratize access by riding Moore's Law, using chip-scale integration to drive cost down as performance scales.
What partners build on
Order kits, register them, follow the sample lifecycle, and pull reports programmatically.
Run a testing program without code: orders, kits, users, reports, and team access.
Give end users an AI assistant grounded in their own biomarker and wearables data.
