London-based Assurix secures £500k seed funding for MSP trustmark platform

A live-evidence trustmark platform designed for Managed Service Providers (MSPs) has raised an estimated £500k seed round for London-based Assurix Limited. The company provides a verification system that confirms security and operational standards through direct integrations with tools such as PSA, RMM, Microsoft 365, and backup software.

Built by industry professionals for their peers, the startup was incorporated in April 2025 to address the difficulty of demonstrating maturity and resilience to small and medium-sized enterprise clients while helping them stay ahead of regulation. By aligning with the UK Cyber Assessment Framework (CAF 4.0) and the upcoming Cyber Security and Resilience Bill, the technology tracks more than 60 operational and security controls to satisfy insurers and regulators.

This latest investment values the business at an estimated £42.1b post-money. The company currently employs 13 people and serves more than 75 customers. Formal documentation for the round was filed in March 2026 (with an allotment date in the same month).
