2. Company History and Business Evolution

Atom Bank was founded in 2014 by Anthony Thomson, a seasoned entrepreneur who previously co-founded Metro Bank, and Mark Mullen, who became the CEO. The bank was born out of a vision to create a bank that fully leveraged the capabilities of smartphones and mobile technology, eliminating the overheads and friction of traditional branch-based banking. After receiving its banking license in June 2015, Atom Bank launched its app in April 2016, initially offering savings accounts and later expanding into mortgages and business lending. The early years focused on building a robust digital platform and gaining regulatory approval, with the bank raising significant capital from investors including BBVA and other institutional funds.

Over the years, Atom Bank has achieved several key milestones. In 2017, it introduced fixed-rate savings bonds and became one of the first banks to offer a fully digital mortgage application process. By 2020, the bank had surpassed £2 billion in deposits and expanded its lending portfolio to include business loans. The COVID-19 pandemic accelerated the shift to digital banking, and Atom Bank saw a surge in customer acquisition. In 2021, the bank launched its 'Atom Bank Plan' – a subscription-based service offering enhanced benefits and rewards. More recently, in 2022, Atom Bank secured a new £100 million funding round to fuel growth, particularly in its mortgage and lending divisions. The bank has also invested heavily in AI and machine learning to improve risk assessment and customer personalisation. This evolution reflects Atom Bank's ability to adapt quickly, embrace new technologies, and scale efficiently while maintaining a strong culture of innovation.
