Invoca, now the largest provider of cloud-based inbound call marketing technology, today announced it closed $20 million in Series C funding led by Accel Partners, with participation from previous investors Upfront Ventures and Rincon Venture Partners. The funding will be used to scale operations and further accelerate its annual revenue growth rate of nearly 200 percent.

Invoca was founded in 2008 and has become the standard solution for Fortune 1000 and Inc. 500 companies, including Liberty Mutual Insurance, OpenTable, Answer Financial and DirecTV. In 2013, more than $1 billion of transactions were completed over Invoca's platform. More than 3,000 marketers currently use Invoca's inbound call marketing software every week to generate better leads, higher conversion rates and thus more revenue.

'There are more than 30 billion inbound sales calls from customers to businesses in the US every year. And with the penetration of smart phones and the rapid growth of mobile search, that number will double over the next few years. The simple facts are that inbound phone calls drive much higher close rates and higher purchase values than closing on the Internet. The numbers tell the story,' said Invoca CEO Jason Spievak. 'Accel's track record of driving technology companies to the next level will help us make marketing automation and CRM complete.'

Invoca's patented call marketing automation platform and analytics software provide the complete solution demanded by CMOs -- attribution and analytics, programmatic marketing automation, and integrations with leading marketing systems such as Salesforce, Kenshoo, Marketo, iCrossing, CAKE, Tealium, and HasOffers among others.

'Despite the fact that their highest-value leads arrive through phone calls, CMOs are routinely stymied by the call channel, assuming that it lacks the same measurement and optimization that other digital channels possess. Invoca is changing that mindset by offering the most effective solutions available to enterprise marketers in this channel,' said Accel Partners' Kobie Fuller. 'We believe that CMOs will increasingly drive quantitative ad spends through SaaS automation platforms, and phone calls are becoming a critical component in this effort. Invoca's management team has proven relevant past success from which they are uniquely positioned to build what we consider will be a category defining business.'

'Accel's investment is a vote of confidence for the inbound call channel -- an underserved area of enterprise software where we project considerable growth as the age of smartphones marches forward,' said Michael Boland, senior analyst and VP, Content BIA/Kelsey. 'We're seeing clear hunger among companies in high value categories like insurance and high tech to better capture and track incoming, high-intent phone leads. Invoca is on top of these trends and should continue to lead the segment.'

CMOs are aggressively pursuing marketing technologies that complete and automate the highest value marketing efforts, and for nearly every marketer, an inbound phone call is the highest value source of new business, and often the least transparent. Even though the inbound call channel is a more than $5 billion marketplace in the US today, until Invoca there were no SaaS solutions for inbound call marketing automation.

Kobie Fuller has joined Invoca's board of directors, which also includes Brett Queener (former Salesforce EVP and GM of Marketing Cloud), Josh Jacobs (Global CEO of Accuen and President of Platforms and Partnerships for Omnicom), Mark Suster (Managing Partner of Upfront Ventures) and John Greathouse (Partner of Rincon Venture Partners).
