CallMiner will use the funding to expand and develop new business applications for its speech analytics platform Eureka, which transcribes and scores call centre interactions with customers.

The funding will also aid the company’s channel partner integration and international expansion.

Founded in 2002, CallMiner works with around 400 companies to analyse customer interactions in the form of calls, chats, emails, surveys and texts.

Holger Staude of Goldman Sachs Growth joins the firm’s board of directors in conjunction with the investment.

Staude said: “The convergence of customer interaction analytics and customer experience creates a significant market opportunity. Backed by a strong management team, CallMiner is well positioned to transform the way organisations operate. We look forward to partnering with their team and supporting their continued growth and success.”
