Capacity Lands $92M, Acquires Two Firms to Power Smarter, Voice-First Contact Centers
AI support automation company Capacity has secured over $92 million in new investments and acquired two companies—Call Criteria and Verbio Technologies—as it pushes deeper into the contact centre technology market.
The funding includes $50 million in debt financing from Chicago Atlantic and a $42.6 million close to its oversubscribed Series D round, which also attracted participation from TVC Capital and Toloka.vc. Capacity says it will use the capital to drive product innovation and scale its enterprise offerings, particularly around voice AI and QA automation.
The St. Louis-based company, now profitable with $60 million in annual recurring revenue, is betting on a fully integrated tech stack as large enterprises increasingly look to consolidate their support operations.
David Karandish, CEO, Capacity, said: “Support is more important than ever for brands across industries, but point solutions can’t effectively solve complex issues. New funding is enabling us to bring together the best technologies in our industry to build a complete, AI-powered support automation platform that helps contact centres operate across channels using shared knowledge.”
Expanding the Tech Stack
With its acquisition of Call Criteria, Capacity gains QA automation and speech analytics tools that analyse agent performance and flag coaching opportunities using generative AI. Call Criteria’s founder and CEO, Stomel, will join the Capacity team.
Verbio Technologies, based in Barcelona, brings voice virtual agent technology designed to handle natural, human-like conversations at scale. The solution reduces reliance on live agents while improving customer satisfaction.
The two acquisitions (Capacity’s 10th and 11th) bring expanded capabilities in voice automation, quality assurance, and real-time analytics, core areas of growth as contact centres move beyond basic chatbot deployments.
Capacity’s platform is used by over 20,000 businesses to automate support, improve customer experience, and reduce operational costs across channels.
With a total of $155 million raised to date, Capacity is now focusing on cementing its role as a key provider of AI-first tools for modern support operations, especially for organisations seeking voice-native solutions built for scale.
