Additionally, the support automation platform is accelerating its leadership in Contact Center technology with the acquisitions of Call Criteria and Verbio Technologies. These strategic acquisitions expand Capacity's capabilities in voice AI, quality assurance (QA) automation and speech analytics.

The new investments in Capacity include $50 million from Chicago Atlantic, a private markets investment firm, and a Series D round close at $42.6 million. The company previously announced an initial $26 million fundraise in its Series D round, which was oversubscribed. Capacity will use the Series D proceeds to continue growth and product innovation as part of a compound startup strategy.
