Calibre × DocTap: Connecting digital health with clinical care

Health-tech partnership

Calibre is an applied-AI healthcare company providing personalised, continuous care through dedicated doctors and purpose-built, causal AI. During Calibre’s launch phase, DocTap acted as its clinical delivery partner, providing API-enabled booking, in-person diagnostic testing, clinician review and CQC-registered healthcare infrastructure.

About Calibre

Calibre is a London-based applied-AI healthcare company and CQC-registered care provider pioneering Causal Health: personalised, continuous care focused on understanding and acting on the drivers of a member's health.

Calibre gives every member a dedicated doctor, powered by causal AI, who understands their full health story and stays with them over time. By connecting the dots across each member’s health and using personalised diagnostics, Calibre identifies what matters most and delivers the care needed to improve their members' present and future health.

Calibre has raised $3.3 million from health and technology investors, experienced founders, operators and medical experts. Following its launch phase with DocTap, Calibre secured its own CQC registration in September 2026 and now delivers its clinical care independently.

Connecting a digital experience with clinical care

For digital health businesses, creating the technology and member experience is only one part of delivering healthcare.

When a service also involves diagnostic testing, clinical interpretation and regulated healthcare activity, the digital journey needs to connect with appropriate clinical infrastructure behind the scenes.

DocTap worked with Calibre as its CQC-registered clinical partner during Calibre’s early operational phase, supporting the diagnostic and clinical elements of its member journey while Calibre built toward establishing its own regulatory registration.

A joined-up pathway

Calibre members arranged their diagnostic testing through the Calibre experience. An API integration connected the booking journey with DocTap, where members could attend for in-person sample collection.

Once laboratory results were available, DocTap clinicians provided clinical interpretation and review, supporting the wider health assessment delivered through Calibre.

This allowed Calibre to retain ownership of its product and member experience while drawing on DocTap’s established healthcare infrastructure for the clinical elements of the service during that phase.

The clinical infrastructure behind the experience

Through the partnership, DocTap supported Calibre with:

• API-enabled booking integration, connecting elements of the Calibre journey with DocTap’s clinical systems.
• In-person diagnostic testing, providing the physical healthcare component behind the digital experience.
• Clinician interpretation and review, bringing medical oversight into the pathway.
• CQC-regulated healthcare infrastructure, supported by established clinical governance and escalation processes.

The teams also worked together on the clinical frameworks that supported the service, helping provide a consistent approach while ensuring individual clinical decisions remained subject to professional judgement.

Bringing together two areas of expertise

The partnership allowed each organisation to focus on its respective strengths.

Calibre developed the technology, member experience and wider proactive health proposition, while DocTap provided the clinical delivery and governance supporting relevant parts of that journey during Calibre’s launch phase.

For members, the aim was a connected experience rather than a series of separate healthcare services. Behind the scenes, technology, diagnostics and clinical expertise worked together as part of the same pathway.

How DocTap works with other healthcare businesses

The Calibre partnership is one example of how DocTap can provide the clinical infrastructure behind another organisation’s service. The right model depends on the product, patient journey and level of clinical support required.

Healthcare technology companies

For digital health platforms, apps and technology-led services, DocTap can support integrated clinical pathways including GP care, diagnostic testing, clinical review and API-enabled workflows.

Healthcare & wellbeing providers

For healthcare and wellbeing providers, DocTap can extend an existing service with GP input, diagnostics, prescribing and medical investigations where additional clinical support is needed.
