Jeffrey Martini is leaving e-procurement services firm SciQuest (Nasdaq: SQI) after eight years, and he will be replaced as vice president of worldwide sales by Douglas Keister, the Cary-based company announced Wednesday.

Keister has more than 20 years of sales experience, having worked for companies such as SAP and Oracle. His most recent job was head of sales for Servigistics. He begins his new job next week.

“[Keister] has a successful track record of accelerating growth and building effective sales organizations in the software industry,” said SciQuest Chief Executive Officer Stephen Wiehe. “We look forward to leveraging Doug’s knowledge and expertise as we continue to scale the business.

“We also want to acknowledge the significant contributions of Jeff Martini, who helped SciQuest grow revenue by sevenfold during his eight-year tenure. We wish him the best as he pursues personal interests.”
