Capacity, an AI-powered support automation platform for contact centers, has secured more than $92 million in funding to accelerate its product development and growth. The funding includes a $50 million investment from private markets investment firm Chicago Atlantic, alongside a $42.6 million close of its Series D round, which was oversubscribed.
The latest round brings Capacity's total fundraising to over $155 million in equity and debt. Investors in the Series D round include TVC Capital and Toloka.vc. The company, which reported $60 million in annual recurring revenue and has reached profitability in 2025, plans to use the funds to further its compound startup strategy.
Alongside the funding announcement, Capacity revealed the acquisitions of Call Criteria and Verbio Technologies. These moves enhance Capacity's voice automation, speech analytics, and quality assurance capabilities—key components in improving contact center operations.
“Support is more important than ever for brands across industries, but point solutions can't effectively solve complex issues,” said David Karandish, CEO of Capacity. “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 Centers operate across channels using shared knowledge.”
As enterprises face growing pressure to cut costs while improving customer experience, the demand for AI-driven support solutions continues to rise. Capacity’s approach—combining knowledge management, generative AI, and now expanded voice capabilities—is well-aligned with these market needs.
“Companies are under pressure to improve customer experiences while cutting costs. With Call Criteria and Verbio Technologies, we're strengthening our platform to deliver faster, more personalized and fully automated support,” said Karandish.
Call Criteria, known for its QA automation tools, uses speech analytics and generative AI to help businesses identify coaching opportunities, improve compliance, and boost agent performance. Ryan Stomel, CEO of Call Criteria, will join Capacity as part of the acquisition.
"Traditional QA is slow and subjective," said Stomel. "Together with Capacity, we're automating QA to drive meaningful improvements in every customer interaction."
Verbio Technologies, based in Barcelona, brings intelligent voice virtual agents designed to handle natural conversations and reduce the need for live agent involvement. Its co-CEO Alejandro Terradas will also join Capacity.
“Voice remains the most critical channel for customer experience and loyalty,” said Terradas. “Integrating our voice capabilities with Capacity's platform unlocks next-level customer engagement.”
With these acquisitions, Capacity is building a more robust, all-in-one platform for enterprise support. Karandish noted that Verbio’s scalable voice tech and Call Criteria’s QA capabilities will further reduce costs, increase compliance, and improve agent performance—resulting in better customer outcomes.
“Verbio Technologies has not only built a voice solution with unparalleled conversational capabilities, it is created to scale for enterprise,” said Karandish. “Together, the Capacity platform will be optimized with greater voice AI technology that personalizes and automates.”
Founded in 2017 by David Karandish, Capacity set out to build a support automation platform that streamlines customer and employee interactions across channels. The company now supports more than 20,000 businesses and operates across SMS, web, email, voice, and platforms like Slack and Microsoft Teams.
The firm has steadily grown through strategic acquisitions—Call Criteria and Verbio mark its 10th and 11th deals. Capacity’s team now includes nearly 250 members worldwide, with talent from both acquired companies joining its ranks.
Beyond the lead from Chicago Atlantic, Capacity’s Series D included backing from TVC Capital and Toloka.vc. To date, the company has raised over $155 million across multiple rounds, including both equity and debt. The terms of the two recent acquisitions were not disclosed.
