Zayla Partners has acquired energy industry compensation surveyor Denver-based Effective Compensation Inc. (ECI).

A purchase price was not disclosed. Houston-based Zayla advises boards and management teams on compensation strategy. The addition of ECI expands its portfolio to advisory in midstream, oilfield services and alternative energy, it reported.

ECI was founded in 1991 by owner and CEO Terry Isselhardt, who will continue as president, Zayla reported.

“Zayla Partners has proven to be the most knowledgeable and qualified compensation partner to acquire ECI with a goal to keep the surveys in the valid and quality format for which ECI is best known," Isselhardt said.

Ian Keas, Zayla’s co-founder, said, “Now more than ever, companies need the combination of high-quality analytics and advisory services to help leaders execute their long-term strategy.”

Chris Crawford, Zayla CEO and co-founder, said Isselhardt “developed the gold standard of quality compensation data and analytics for the energy industry over the last three decades.”
