Experian, the global data and technology group, said revenue for the three months to 30 June rose 10% at actual exchange rates, 8% at constant currency and 7% organically.
Chief executive Brian Cassin said the group "delivered a strong start to FY27" and that trading was "in line with our expectations."
North America, which accounted for 67% of group revenue in the last financial year, grew organically by 7%, with business-to-business (B2B) revenue up 11% on strength in Financial Services, Ascend analytics and fraud prevention products.
Consumer Services in North America fell 2% organically, as flagged last quarter, following the wind-down of two long-term mass data breach support contracts; stripping those out, growth was 3%.
Latin America delivered the fastest growth, up 12% organically, with Consumer Services surging 22% on strong performance from Brazil's Limpa Nome service and its credit marketplace.
Experian closed its acquisition of Brazilian digital identity specialist idwall on 1 July, a deal it said will strengthen fraud prevention capabilities in the region.
The UK and Ireland grew 5% organically, with total constant-currency growth of 7% boosted by the KYC360 acquisition, while EMEA and Asia Pacific grew 1%, held back by a strong prior-year comparison from large software deliveries.
Experian said its full-year expectations remain unchanged and will report half-year results for the period ending 30 September on 18 November.
