What Patients Know Best does
Patients Know Best (PKB) is a UK health technology company, founded in 2008 and headquartered in Cambridge, that operates a Personal Health Record (PHR) platform organised around a Single Patient Record (SPR) architecture. PKB aggregates clinically coded health data from hospitals, GP systems, connected devices, and patient contributions into a unified, patient-controlled record, delivering it via web, mobile, and the NHS App to over 6.9 million registered users and roughly 22 million test results each month. It was the first PHR to integrate with NHS Login in 2019 and serves more than 20 NHS Trusts across England and Wales, along with international deployments in the Netherlands, Germany, Ireland, Saudi Arabia, and Nigeria.
The technical foundation is a FHIR-native platform with a vendor-neutral archive and bidirectional FHIR APIs, supported by HL7 messaging (ADT A28, SIU, ZRX), SNOMED-CT (England) and ICD (Netherlands) coding, and proprietary single sign-on by NHS number. The product portfolio comprises the core PKB Platform, vertical modules for Mental Health (with the first NHS Wayfinder adaptation for Mental Health Trusts), Elective Recovery (delivered through a 2025 partnership with Feedback Medical's Bleepa platform), and a Population Health Management Engine launched in July 2025 to automate cohort identification for clinical trial recruitment. Compliance posture includes NHS England ITP endorsement, SOC 2 Type II, Cyber Essentials, GDPR compliance, and B Corp certification since 2015.
PKB runs a B2B/B2G subscription model in which the platform is free for patients and funded by healthcare organisations on multi-year contracts; it sells to NHS Trusts and health boards through enterprise field sales and NHS framework procurement, supported by a product-led growth motion in which patient self-registration via the NHS App drives organisational adoption. International expansion is pursued through direct licensing with ministries of health, regional authorities, and academic medical centres, as illustrated by the 2025 Al Maarefa University partnership in Saudi Arabia and the Lagos single patient record contract with Interswitch Group in Nigeria. Structured as a Certified B Corporation, PKB employs 51–100 people and reports Mohammad Al-Ubaydli as founder and CEO, with a leadership team covering engineering, customer success, and finance.

Patients Know Best competitors and assessment
Company assessmentDirect peers
- TPP: UK-based EPR vendor whose SystmOne platform is widely used across NHS GP practices and Trusts, with its own patient-facing record capabilities. Directly competes for the same NHS digital-strategy spend as PKB.
- DrDoctor: UK digital health company providing patient engagement, appointment management, and waiting-list validation tools to NHS Trusts. Competes with PKB for the patient-communication and appointment-management portion of the digital front-door.
- Epic Systems (MyChart): Epic's MyChart is the dominant patient portal/PHR in US health systems and is expanding into UK NHS Trusts through EPR deployments. It is the most direct substitute for PKB's patient-facing record and care plan functionality.
- EMIS Health: UK primary-care clinical system provider (EMIS Web) with a patient-facing service (Patient Access). PKB already integrates with EMIS via SSO and EMIS Extract, making it a closely adjacent competitor and integration partner.
- GetWellNetwork (GetWell): US-based patient engagement and digital care management platform, including PHR-style functionality. Closest US analogue to PKB's patient-engagement plus care-plan model for hospitals and health systems.
- Oracle Health (Cerner Patient Portal): Oracle Health (formerly Cerner) offers a patient portal as part of its EPR suite and is increasingly active in NHS Trust procurements, posing bundled-competition risk to PKB's independent PHR model.
Emerging players
- Huma (formerly Medopad): Digital health platform offering patient-facing apps, remote monitoring, and digital biomarkers. Increasingly active with NHS Trusts, competing for the same digital-front-door and remote-monitoring budget pools as PKB.
- Livi (formerly KRY): European digital primary-care provider with patient apps for record access, consultations, and chronic-condition management. Competes for the same patient-engagement and self-management use cases in NHS Trusts.
- Lumeon: UK-US care-pathway automation platform for hospitals and payers, addressing referral, scheduling, and patient communication. Adjacent to PKB's elective-recovery use cases and likely to compete or partner on pathway workflows.
Regional players
- Babylon Health: UK-headquartered (now part of eMed) digital health platform offering patient-facing health record and consultation services. Historically active in NHS partnerships and a relevant benchmark for UK PHR and triage use cases.
