London-based Rellen Ltd raises £50k for AI interview intelligence

An estimated £50k has been raised by Rellen Ltd, a London-based developer of interview intelligence software. This latest round brings the total capital secured by the firm during 2026 to £600k. Incorporated in January 2025, the business specialises in facial behaviour analysis and conversational insight.

The company's core product is SecretSight, a patent-pending computer-vision platform that identifies markers of unreliable information in real time. This technology is marketed to organisations within the banking, insurance, law enforcement, immigration, and border security sectors to address the hidden costs of unsuccessful conversations. It aims to mitigate the impact of cognitive overload and training gaps by offering a scientifically robust layer of machine learning.

Rellen Ltd reports that its technology can reduce interview-related processing by up to 30% while increasing successful case outcomes by 15% through the surfacing of missed lines of enquiry. The firm currently operates with a team of five employees. Documentation for this latest capital injection was filed in August 2026.
