CHARLOTTE, N.C. — Scientigo, a developer of local and mobile search technology, has replaced its chief executive officer.

Cynthia White, the company’s president and chief operating officer, took over the CEO role last week. Scientigo’s board of directors voted unanimously not to renew the employment contract of Doyal Bryant, the CEO, when his agreement expired on Oct. 23.

Bryant is a board member and will remain on the board, the company said in a statement.

As part of the leadership change, Scientigo said it would concentrate on two initiatives: a local search platform to support enhanced directory assistances as well as a product for enterprise content management.
