The appointment follows Embark’s acquisition of the ATS advised client book last year.
She will oversee the propositions for the Embark platform and Advance by Embark.
The divisions provide digital wealth and retirement solutions for financial advisers and corporates and use FNZ’s platform-engine’ technology.
Ms Wilson has been head of platform propositions at ATS since 2013 after joining from Standard Life. She previously worked for Xansa, a technology outsourcing company.
Dave Lowe, group head of propositions, Embark Group, said: “Sara’s deep platform experience will be invaluable.”
Ms Wilson said: “It’s an exciting time to be moving over to Embark and I look forward to developing its platform offerings for both advisers and corporates, to help meet client needs in 2021 and beyond.”
Earlier this week Embark reported it had migrated over £7 billion of advised assets onto the Embark platform from the client books of Alliance Trust Savings (ATS), including those from trading service provider Stocktrade, which it acquired in October 2019.
The takeover of ATS’s client book means that Embark’s platform now hosts the savings and investments of more than 41,000 additional clients and 30,000 accounts. More than 100 ATS employees have also joined the Embark team.
The acquisition has increased overall Embark assets under administration to £38.5bn for about 415,000 consumer clients.
