Linguistic Factory is a Madrid-based conversational AI company that builds chatbots, voicebots and hyperrealistic 'digital humans' powered by natural language understanding and neural synthetic voice. Its avatars handle sales, customer service, HR and training use cases, with the company claiming ~90% intent-recognition accuracy from first deployment and focusing on healthcare and retail/e-commerce verticals. Founded in 2021 by ex-Bitext executive David Fernández Rubí, it is an early-stage (seed) startup of roughly 11-50 people, backed by the COREangels network and supported by Spanish/EU recovery-plan digitalisation funds.
