Sesame has successfully recruited 80% of former Thinc Network advisers, following a fast-track arrangement.
As part of it's transformation into Bluefin, Thinc Network was shut down in April, leaving almost 150 advice firms without a network.
A deal struck with Sesame meant advisers could be quickly moved over to the network, with minimal interruption to their business.
Nick Kelly, managing director of Sesame, says 80% of Thinc firms have signed up so far, and expect more to join the network in the coming weeks.
"Thanks to the fast-track process we arranged with Bluefin and the FSA, most of the firms are already up and running and are able to do business," he says.
"It was very important we had continuity for firms, and the fast track process means clients don't go without a service and firms don't suffer a commission freeze."
Sesame remains in discussions with other firms who have not made up their mind, and Kelly is hopeful others will soon decide to join the network.
"This is an important decision for the firms involved, and we're supporting them with all the information they need to make that decision."
