Tech PR maven Andy Cunningham has left the CEO post at San Francisco's Bite Communications after six months to focus on SeriesC, her marketing and consulting venture serving startup companies.

andy cunninghamCunningham, who joined Bite as president in January 2012, said in an email to industry colleagues July 2 she made the decision to focus "all my attention" on SeriesC, which is located in Bite's Spear Street offices. Bite parent Next Fifteen Communications Group is a minority investor.

Cunningham's tech credentials include a key term at Apple and founding Cunningham Communications, acquired by Incepta in 2000. She said SeriesC is "getting a lot of traction in the market lately" and is currently engaged with four clients in the energy efficiency, display components, media/publishing and education spaces.

Her team includes around ten former colleagues and tech sector alums.

She noted the difficulty of startups to innovate and get to market. "The noise is deafening and the competition fierce," she wrote.

Next Fifteen CEO Tim Dyson, who takes the interim reins of Bite, has merged Bite with U.K. digital marketing shop Bourne under the Bite banner.
