U.K.-based challenger bank, Starling Bank, has added digital investment service Wealthify to its startup marketplace, enabling users to share their Starling data with the service, the companies announced today.

Backed by Aviva, Wealthify is an online investment company based in Cardiff. It joins existing partners on Starling’s marketplace including mortgage brokerage Habito and receipts provider Flux.

Its integration goes a little further than previous partners, however, as Megan Caywood, chief platform officer for Starling, told TechCrunch:

When a customer clicks ‘add’ from within Starling, new Wealthify users are then asked if they’d like to securely share Starling data with Wealthify (e.g. name, DOB, address, etc as well as account number and sort code for setting up the direct debit, if they want). And if they say yes then that auto-populates many of the fields in the Wealthify setup.

Starling is looking to provide this two-way integration with all of its partner services on the marketplace, effectively moving towards the next phase of open banking — banks with platforms offering a suite of third-party services to their customers.
