<h2>💬 Accurx is where conversations happen with and about patients.</h2><p style="min-height:1.5em">For decades, the NHS has struggled with fragmented systems that make simple tasks feel impossible. We’re changing that by building a single, system-wide platform that connects everyone through communication.</p><p style="min-height:1.5em">What started as a way for GPs to text a patient has now evolved into an all-in-one digital toolkit used by 98% of GP practices.</p><p style="min-height:1.5em">Our platform now powers Total Triage to manage patient demand, and Self-Book, which lets patients schedule their own appointments in seconds. We’ve automated routine care with Patient Questionnaires for long-term conditions, while Accumail finally allows staff-to-staff communication to happen instantly across different care settings. We’re now pushing the boundaries of the consultation itself with Accurx Scribe, our AI-powered note-taker that drafts medical notes in real-time.<br /></p><p style="min-height:1.5em"><strong>The team</strong></p><p style="min-height:1.5em">We are a mission-driven team of 80 engineers based in London and the surrounding areas, united by the challenge of fixing healthcare communication. We are innovating for the NHS at a scale and depth that has never been done before, solving the real-world problems that stand between millions of patients and the care they need.</p><p style="min-height:1.5em">We are a highly cross-functional group where engineering, product, data, and security collaborate as true peers.
