The Newport-based firm hailed “organisational and operational transformations” made at the start of the year after it was spun out of insurance giant esure last November.
Boss Matthew Crummack said trading had been boosted by the changes, with improvements set to ramp up over the rest of the year.
Gocompare, which allows customers to compare rates of insurance policies, financial products and energy tariffs, is expecting to post half-year underlying operating profits of around £17.5 million.
It said sales rose 4% to around £75.8 million in the six months to June 30.
The group also announced its first strategic investment, with a minority stake bought in digital “robo-adviser” Mortgage Gym, which is set to launch in September.
