Jacquie Boast, New Millennium Technologies' (NMT) marketing manager, is leaving the insurance software house after five years.
Boast said she was moving to a technology company outside the insurance industry, which she declined to name. She leaves NMT at the end of the month.
Barry Singh, NMT's managing director, said: “Jacquie's contribution to NMT's development has, of course, been very important over the past five years.
“We respect Jacqui's desire to take up a new challenge and wish her every success in the future.”
