Mantis NLP
Mantis NLP helps organisations unlock AI value through NLP consulting, agentic AI solutions, and responsible AI strategy.
About
Mantis NLP is a London-based AI consultancy — with additional offices in Valencia and Nicosia — that helps organisations innovate and create sustainable value through natural language processing and large language models. Founded in 2021, they work with clients to identify high-impact AI opportunities, redesign business processes, and deploy agentic AI solutions tailored to specific organisational needs.
Their work spans healthcare, telecoms, pharmaceutical, retail, and charitable sectors. Named clients include GSMA, The Wellcome Trust, Oxford Medical Simulation, and dmTech. Mantis takes a pragmatic, ethics-first stance — building internal capacity within client teams rather than creating dependency, and prioritising responsible and environmentally conscious AI over trend-driven implementation.
