Capacity, an AI-powered support automation platform for Contact Centers, has secured over $92 million in fresh funding to accelerate product innovation, integrate voice AI advancements, and enhance customer experience solutions.

The investment includes $50 million in debt financing from Chicago Atlantic and $42.6 million from a Series D equity round led by TVC Capital and Toloka.vc. This funding brings Capacity’s total raised capital to more than $155 million.

With this infusion, the St. Louis–based company aims to expand operations, roll out new AI capabilities, and execute its compound startup strategy by integrating recent acquisitions.

Meanwhile, David Karandish, CEO of Capacity, said, “Support is more important than ever for brands across industries. Still, 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 Centers operate across channels using shared knowledge.”

Driving the Future of Contact Centers

CEO David Karandish said that the new capital will enable Capacity to push the boundaries of AI in contact center automation, while delivering measurable cost reductions and revenue gains for clients.

By blending practical and generative AI, the platform deflects tickets, emails, and calls, freeing teams to focus on higher-value work and elevating the customer experience.

The startup is redefining how contact centers operate by putting artificial intelligence at the heart of customer service. Instead of relying solely on human agents to answer every phone call, email, or message, its AI-powered platform can respond instantly across multiple channels, web, SMS, voice, social media, and workplace tools like Slack and MS Teams.

The system doesn’t just provide quick replies, it understands the question, finds the correct answer from a company’s knowledge base, and can even guide customers through solving problems without human involvement. When complex issues arise, it equips live agents with the exact information they need, cutting down call times and improving resolution rates.

Expanding AI Capabilities Through Acquisitions

Capacity has strengthened its technology portfolio by acquiring Call Criteria and Verbio Technologies. Call Criteria delivers AI-driven QA automation and speech analytics to help businesses identify coaching opportunities, boost compliance, and improve agent performance.

Verbio Technologies, headquartered in Barcelona, develops Intelligent Voice Virtual Agents capable of managing complex customer interactions, reducing wait times, and limiting reliance on human agents without compromising satisfaction.

With the recent acquisitions of Call Criteria and Verbio Technologies, Capacity now incorporates advanced voice AI, speech analytics, and quality assurance automation into its offerings. This combination enables companies to identify training needs, ensure compliance, and refine service quality in real-time.

The result? Customers get help faster, agents focus on meaningful problem-solving, and businesses reduce costs while improving satisfaction scores. Capacity’s $92 million funding round will fuel even more innovation, pushing the boundaries of what contact centers can achieve in the age of AI.

“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 David Karandish.

Industry Reach and Revenue Momentum

Since its founding in 2017, Capacity has served over 20,000 companies across industries, providing both external customer support and internal employee enablement. Its platform integrates with various channels, including web, SMS, email, voice, social media, Slack, MS Teams, and multiple helpdesks. The company reported strong growth in 2025, achieving profitability with $60 million in annual recurring revenue.

“Voice remains the most critical channel for customer experience and loyalty. Integrating our voice capabilities with Capacity’s platform unlocks next-level customer engagement,” said Alejandro Terradas, co-CEO of Verbio Technologies.
