Ascentric and its institutional arm IFDL have seen two consecutive quarters of record net inflows.
Net new business was up 39 per cent over the same period last year to £813m, giving the firm its strongest-ever first half performance.
The collective performance of the two firms saw total assets hit £6.6bn, an increase of 43 per cent against the first half of 2012.
More than 350 adviser firms signed up to the IFDL and Ascentric platforms and around 9,000 new customers were added to the platform in the first six months.
This took total customers to 50,073, a 35 per cent increase against the first half of 2012.

Hugo Thorman, managing director of Ascentric and IFDL, said: "We have enjoyed a fantastic first half to the year driven by two consecutive quarters of record net new business. The rate of adoption in terms of net inflows and sign ups has exceeded our expectations and shows the degree to which advisers are willing to embrace transparent wrap platforms in a post-RDR world.
"Demand for platform functionality continues to grow and we will look to meet those needs by rolling out a series of technology developments over the next year that I hope will enable us to deepen the relationships we have with our clients and help us achieve yet further milestones."
