The new partners are online buy-to-let mortgage lender Molo Finance; UnderPinned, which is a career-management platform for freelancers; and PayStream, a provider of digital accounting services for contractors.

This takes the total number of integrations available in the bank’s Marketplace to 24, all of which link with customers’ accounts and data, and are accessible in minutes via a few taps of the Starling banking app.

Other partners include accounting software packages Xero and QuickBooks and Legal Services provider Sparqa Legal.

Starling CEO and founder, Anne Boden said: “Today’s entrepreneurs have grown accustomed to operating in a world where digital services are crafted around their particular needs. They expect the services they are offered to match closely with their business types, locations, and customer demographics.

“We believe that the Starling Business Marketplace is exceptionally well-suited to meeting such expectations, by giving businesses access to a range of services within the app they use for their everyday banking.”

Molo’s goal is to simplify the process of getting a buy-to-let mortgage by cutting out intermediaries. It intends to start offering residential mortgages in 2020.

Francesca Carlesi, co-founder and CEO of Molo, said: “Making easier, faster, fairer mortgages available to as many people as possible is something we’re truly passionate about, and having the support of Starling, an organisation creating such positive change in the industry, is invaluable. We’re excited for what’s to come and thoroughly look forward to working together.”

All partners are covered by the Starling Promise of no hidden mark-ups, so account holders pay the same as they would if they went direct to the provider.
