What Lang.ai does

Lang.ai, founded in 2018 and headquartered in Madrid, Spain, operated as an AI-native conversation analytics platform that converted unstructured customer interactions across voice, chat, SMS, and helpdesk channels into structured insights and automated workflows for enterprise customer experience (CX) teams. The company's core technology combined natural language processing, proprietary natural language query tools, agent-based AI systems, and interaction intelligence capabilities that allowed non-technical users to query customer interaction data in plain English and surface trends, escalation drivers, and performance metrics without manual reporting. In 2025, Lang.ai extended into generative AI by building analytics agents on Snowflake's Native App Framework, broadening its product surface beyond the original CX tagging use case.

Lang.ai generated revenue through a B2B SaaS subscription model with enterprise sales motion, targeting CX teams across industries that needed to scale support operations without proportional headcount growth. The company raised $15 million in total venture funding, including a $10.5 million Series A led by Nava Ventures in May 2022 and an earlier round led by Village Global. Operationally, Lang.ai ran as a lean team of 11–50 employees and was partially owned by Alma Mundi Ventures prior to its acquisition.

In April 2026, Capacity acquired Lang.ai to integrate its natural language query tools and agent-based systems into Capacity's broader AI-powered support automation platform, which serves more than 20,000 companies and processes over 36 billion automated interactions. Founder Jorge Penalva joined Capacity to lead AI analytics, and the Lang.ai brand now operates as "Lang by Capacity." The acquisition reflects consolidation in the agentic AI analytics segment for customer support.
