Winchester Insurance Systems' 2001 results showed turnover was up by 91% to £3.25m, with a profit of £75,000.
Managing Director Ray Vincent said: "These results make WISL the fastest growing solutions provider in the insurance sector. I think we can be very proud of this achievement given the prevailing market conditions for technology companies."
He added: "The extremely positive results have arisen from a combination of new sales and repeat business from our existing Transactor user base."
WISL launched two new systems in December 2001 - Transactor Common Application Support (CAS) and the Transactor Enterprise Solution (TES). Future growth will be based on marketing these solutions which already have advance orders worth £3m.
