TrueLayer's take on their challenges in 2021

Francesco Simoneschi

Founder and CEO

While 2020 was undoubtedly a challenging year as we all adjusted and adapted to fully-remote working practices, it was still one of many positives. TrueLayer saw significant growth, broadening our services to France, Germany, Italy, and Spain, and partnering with companies including Revolut, Nutmeg, and Freetrade to deliver open banking capabilities to millions of customers across Europe.

We raised $25m in funding under our Series C to continue investment in our open banking platform and scaled our commercial, design and engineering teams to meet demand for our open banking platform. In 2021 we expect that growth to continue as more consumers and business embrace open banking.

We have ambitious plans and a number of product launches around some interesting use cases that go beyond account aggregation and payments. We also see interest in open banking capabilities in new verticals such as wealthtech and igaming, and within e-commerce and marketplaces as they look for way to embed payments into their platforms.

Our take on TrueLayer

Freddie

Company Specialist

Fintech innovation has been pushed further by the introduction of Open Banking standards. Financial institutions are now required to host APIs that allow sharing of your financial data, and you are in control of which third parties have access. It has never been easier for finance products to interact with each other. For example, you may be able to view your Halifax credit card transactions from your Monzo account.

The technologies and partnerships to build this financial layer are complex. TrueLayer saw this problem early, and started years before the standards were enforced.

TrueLayer has made the most out of the London fintech scheme with key partnerships (e.g. Monzo, Revolut) and is now expanding fast in Europe. Their role as the ‘connecting layer’ is incredibly defensible. As TrueLayer's partnerships continue to increase, the value of its platform becomes harder to replicate. Particularly as its offering now has a global reach.
