What Syndi Health does
Syndi Health is a London-based digital health startup that built an AI-driven recommendation platform for personalizing mental health and wellbeing services. Founded in 2023, the company's core product used artificial intelligence to match employees with appropriate digital health solutions, processing text-based assessments to generate personalized wellbeing recommendations for B2B customers. The platform was deployed through pilot programs with NHS trusts in Cornwall and Plymouth and tested with private healthcare providers and employers, targeting the workplace absenteeism and preventative care markets in the United Kingdom.
The company operated on a B2B subscription model, selling access to its AI platform to healthcare providers, insurance companies, and employers seeking to offer flexible mental health and wellbeing benefits. In February 2023, Syndi Health raised £1.65 million ($2 million) in pre-seed funding from UK health, technology, and insurance investors alongside a £400,000 non-dilutive Innovate UK grant, with proceeds directed toward platform development, team expansion, and NHS pilots. On 1 May 2025, Syndi Health was acquired by HealthKey, a UK-based healthcare marketplace platform serving employers, insurers, gyms, benefit platforms, and individuals; Syndi Health's clinical assessment technology is being integrated into HealthKey's broader platform, which claims access to 75 healthcare providers through a single integration.
