AI agent developer Cosine X secures £69.9k at £3.5m valuation

A new funding injection of £69.9k has been secured by Cosine X Ltd, a London-based developer of business and domestic software. This transaction establishes an estimated post-money valuation of £3.5m for the business.

The company was incorporated in August 2025 to provide AI-driven agents for regulated sectors. These platforms are designed for organisations that require auditability and human oversight within their operational workflows.

The product suite includes XENI for end-to-end immigration-law casework and Robolab X for K-12 educational learning. A third platform, Metaroom, manages compliance-focused tasks for finance, advisory, and insurance firms.

Total funding raised by the startup during 2026 now stands at £174.9k. The share allotment for this specific round took place in September 2026 (with formal documentation filed during the same month).
