As a leader in open banking infrastructure, TrueLayer provides a secure, reliable, and developer-friendly platform that enables businesses to connect directly with major banks and financial institutions across Europe and beyond. The company’s mission is to make financial services more accessible, transparent, and efficient by leveraging standardized APIs that comply with PSD2 and other regulatory frameworks.

TrueLayer serves over 300 businesses, including fintech startups, neobanks, e-commerce platforms, and traditional financial institutions. Its technology processes billions of pounds in transactions annually, making it a trusted partner for companies like Revolut, Stripe, and Coinbase. The company’s reputation for security, speed, and innovation has earned it recognition as a leader in the open banking space, with multiple awards including Fintech Startup of the Year and inclusion in the Deloitte Tech Fast 50.

With a workforce of over 400 employees, TrueLayer fosters a culture of engineering excellence, collaboration, and continuous learning. The company’s platform handles high-volume, low-latency requests, requiring robust infrastructure and cutting-edge technologies such as Go, Rust, Kubernetes, and event-driven architectures. TrueLayer’s commitment to open standards and transparent data sharing positions it at the forefront of the financial revolution, empowering consumers and businesses alike to take control of their financial data.

Company History and Business Evolution

TrueLayer was founded in 2016 by Francesco Simoneschi and Luca Martinetti, two Italian entrepreneurs with a vision to democratize access to financial data. The founding team recognized the potential of PSD2, the European payment directive that mandated banks to open their APIs to third parties, and set out to build a unified platform that could abstract the complexity of connecting to hundreds of different bank APIs.

The company started as a small team in London, developing its first API integrations with UK banks. By 2017, TrueLayer had secured £3 million in seed funding from investors including Northzone and Anthemis Group, enabling it to expand its engineering team and accelerate product development. In 2018, TrueLayer launched its payments API, allowing merchants to accept bank transfers directly, bypassing traditional card networks and reducing transaction costs.

The following years saw rapid expansion. In 2019, TrueLayer raised £14 million in Series A funding, followed by a £35 million Series B in 2020 led by Temasek and Balderton Capital. The company used these funds to expand into continental Europe, opening offices in Milan and later in Dublin. In 2021, TrueLayer achieved unicorn status with a $1.3 billion valuation after a $130 million Series E round, cementing its position as a market leader.

Key milestones include the acquisition of Nordic open banking startup, Instantor, in 2021 to enhance its data analytics capabilities, and the launch of TrueLayer Signals, a real-time fraud detection product. The company also partnered with major retailers like ASOS and Deliveroo to offer instant bank payments, reducing checkout friction and improving conversion rates.

Today, TrueLayer processes over 20 million API calls daily and supports more than 50 bank integrations across Europe. Its evolution from a small startup to a global fintech infrastructure provider reflects the growing adoption of open banking and the increasing demand for digital financial services.
