Nine months after announcing that its president and chief executive officer will be stepping down, Blackbaud has appointed an interim president and CEO while a permanent successor is sought. Senior Vice President and Chief Financial Officer Anthony Boor was appointed interim president and CEO, effective Aug. 31, until a permanent CEO is hired.

Marc Chardon, who helmed the Charleston, S.C.-based fundraising and software company since 2005, announced in January that he would be leaving by the end of this year. His last day with the company is Friday. During his tenure, Blackbaud acquired at least five companies for a total $430 million, including acquisition of rival Convio for $275 million in May 2012.

The search for a new CEO has been underway and active. “The main focus of the search is not just to fill the role – the board is committed to taking the time necessary to make sure we find the right candidate to lead the company’s next phase of growth,” Blackbaud spokeswoman Melanie Mathos said. “The board is looking for an external candidate and looks forward to Tony’s ongoing contributions as CFO after a permanent CEO is appointed,” she said.

The 50-year-old Boor joined Blackbaud in 2011 and during his time as CFO drove the execution of the Convio acquisition, according to the firm, resulting in gains in EBIT margins for the combined company. Prior to Blackbaud, Boor was executive vice president, chief financial officer and treasurer of Brightpoint, Inc., a wireless device company based in Indianapolis, Ind.

Founded in 1981, Blackbaud became a public company in 2004 and has approximately 2,800 employees worldwide.
