Vectify AI is a London-based AI infrastructure startup founded in 2023, led by UCL postdoctoral researcher Mingtian Zhang and co-founder Yu Tang. The company is rethinking how AI systems retrieve information from long documents, replacing conventional vector-database search with hierarchical tree indexing and multi-step LLM reasoning — an approach that reached state-of-the-art accuracy on financial-document benchmarks.
