Bob Neveu, Certify’s cofounder and CEO, told Maine Startups Insider that the deal closed in late May and was structured as a “majority recapitalization,” in which K1 bought out 100 percent Certify’s investors from its Series A and B rounds in 2009 and 2014, respectively. Neveu said the total investment the company had acquired in those earlier rounds was $5 million. K1 is now the majority shareholder of Certify, though Bob Neveu his brother Alan, Certify’s CTO, remain minority shareholders. Neveu and his brother plan to remain in their respective roles and the deal will not have an adverse impact on the company and its local operations, he said. The company currently employs roughly 90 people across three offices in Portland. The Neveu brothers founded Certify in 2008 to offer expense management software. It was the first company in the space to offer users the ability to capture receipts with the camera on their Blackberries or Smartphones. The company has grown rapidly. Its average compounded annual growth rate over the past five years is 71 percent, according to Neveu, though he wouldn’t offer specific numbers. While not a total exit for Neveu and his brother, this is the second major liquidity event the pair have experienced. Bob and Alan cofounded Recruiternet in Portland, which First Advantage acquired in November 2005. A deal of this size sends a positive message to Maine’s startup community about what’s possible, Neveu said. Those early investors who K1 bought out include Maine Venture Fund and Portland-based CEI Ventures. TechCrunch reported in 2009 that early investors also include FluffCo, Transactis CEO Joe Proto, angel investor Esther Dyson, and Alpine Meridian CEO William Benedict. This is the second major liquidity event the Neveu brothers have experienced in Portland. Bob and Alan co-founded Recruiternet in Portland, which First Advantage acquired in November 2005. That acquisition was the Maine Venture Fund’s first big exit (though it was known as the Small Enterprise Growth Fund at the time). So when the Neveu brothers founded Certify a few years later and approached MVF about investing, they knew the team was solid and made the investment, according to John Burns, MVF’s managing director. MVF invested a total of $500,000 in Certify across both rounds in 2009 and 2014. From the K1 acquisition, MVF realized a 6x return, meaning it pocketed roughly $3 million from the deal, which will now be available to invest in other Maine startups. Nat Henshaw, managing director at Portland-based CEI Ventures, declined to comment on the deal or answer questions about its investment in Certify or its return. K1 has been involved in the expense management software space for the past 18 months and has spent $25 million acquiring some other companies in the space (Nexonia, ExpenseWatch, and Tallie), which it will now place under the Certify umbrella. The result of which, Neveu said, is that Certify overnight doubled its revenue and tripled its number of customers to more than 800 corporations. Neveu wouldn’t reveal pre- or post-deal revenue figures, but said it is now the largest independent expense management software company.
