Subjct secures £25k to expand AI search engine optimization platform

Subjct Limited, a London-based software developer incorporated in 2023, provides an automated content optimization platform focused on brand discovery in AI search engines. The company uses machine learning and natural language processing to build topical authority through Generative Engine Optimization.

The business recently raised £25k in a funding round that places its estimated post-money valuation at £1.8m. This follows two pre-seed rounds completed in February 2026, which raised a combined £250k at valuations of £1.8m and £1.9m.

The platform automates internal linking and creates semantic topic clusters to optimize content for entities. It also generates data layers for brands by linking schema to the Google Knowledge Graph and provides automated article tagging to maintain relevance across content archives.

Entity analysis tools within the software allow users to identify topical strengths against competitors. For the financial year ended 31 December 2024, the company reported two employees, while current LinkedIn data suggests a total headcount of four. Earlier funding history includes a £100k raise at a £1.6m valuation and a £25k raise at a £1.5m valuation, both occurring in March 2025.
