Wealthify – which is backed by insurance company Aviva – offers low-cost Isa and general investment plans, containing investments such as shares, bonds, property and commodities.

Starling's in-app marketplace provides its customers with direct access to financial services and products securely on their phone.

As a result of this new partnership, Wealthify will be available to all Starling customers, while Wealthify customers can now get an overview of their investments via their Starling account.

“At Starling, we're on a mission to deliver our customers the best banking experience in the world,' said Megan Caywood, chief platform officer at Starling Bank (pictured above).

“By partnering with innovative and disruptive companies, such as Wealthify, we're aiming to bring the best financial services and products directly into our customer's pockets through our in-app marketplace.

“We are excited to welcome Wealthify and look forward to announcing more partnerships soon.'

Michelle Pearce, chief investment officer at Wealthify, said the open architecture marketplace that Starling had created was a vision of the future of banking.

“Their simple and transparent approach is perfectly aligned with our mission to democratise investing, by breaking down the common barriers holding people back, such as lack of confidence, the belief that you need to be an expert to invest, or thinking you need lots of money.

“We're extremely excited to partner with Starling Bank and pleased to be able to offer their customers easy access to Wealthify investment services through the in-app marketplace.'
