TrueLayer, the London startup that offers a developer-friendly platform for companies, including other fintechs, to utilise open banking, is disclosing $70 million in new funding.

The Series D round is led by new investor Addition. Existing investors, including Anthemis Group, Connect Ventures, Mouro Capital, Northzone and Temasek, also participated. New investors include Visionaries Club, Zack Kanter (CEO Stedi), Daniel Graf (ex-Uber, Google, Twitter) and David Avgi (ex-CEO SafeCharge, CEO UniPaaS).

TrueLayer says the Series D brings the total investment to date to $142 million. The injection of capital will be used to continue scaling its open banking network, which brings together payments, financial data and identity to enable companies to build new products that improve “how we spend, save, and transact online”.

This will include further development of premium open banking-based services that go beyond simply accessing open banking APIs and will enable more innovation across financial services, including embedded finance and payments more generally.

To do this, and to support what it says is growing demand, TrueLayer is expanding its engineering, product and commercial teams. In the past 12 months, the fintech has expanded its services across 12 European markets.

Over the years, TrueLayer CEO and co-founder Francesco Simoneschi and I have often pontificated on what open banking’s killer use case or use cases may turn out to be. We may finally have our answer: payments.

That’s because one aspect of open banking is payment initiation, which lets an authorised third party initiate the transfer of money out of your bank account on your behalf as an alternative to card payments, which were never built with online payments in mind.

“We believe open banking payments will become the default way to pay online, replacing other payment methods in the next five years,” says Simoneschi. “Open banking is digitally native and mobile-first, moving money at a fraction of the cost, securely and conveniently, while also delivering a vastly better consumer experience.”

The past year has also exposed some of the problems with existing payments methods, as people have turned to digital channels to manage every aspect of their lives. “The problem is cards,” says the TrueLayer CEO, “which weren’t designed for online and have been retrofitted into current online payment flows. Newer digital approaches such as Google Pay or Apple Pay paper over those cracks but don’t change the fundamentals."

Simoneschi says the company has seen the use of its payments API grow rapidly as more consumers embrace instant bank payments. Volumes grew by 600x over the last year, driven by more and more companies adopting open banking payments, including the likes of Revolut, Trading 212, Freetrade and Nutmeg.

“We typically see that 1 in 3 customers choose the open banking payment option after trying it once,” he notes, revealing that for some clients, closer to 70% of their customers are using open banking as the primary payment method.

“There are a number of reasons why it makes sense for customers. For one, they don’t need to remember card details. Instead, they authenticate with their face or fingerprint on their mobile device, instantly and securely. Plus, they’ll never need to update stored details if their card is lost, stolen or expires.”

Open banking payments as a checkout option benefits merchants too, argues Simoneschi. “These payments typically convert 20% better than cards (and up to 40% with our flows) and have success rates higher than 95%, equating to millions or hundreds of millions in recovered revenue at the end of the year,” adds the TrueLayer co-founder.
