2015–2017: Early growth Monzo Bank was founded as
Mondo in 2015 by
Tom Blomfield and his team. The team originally met whilst working at
Starling Bank. In February 2016, Monzo set the record for "quickest
crowd-funding campaign in history" when it raised £1 million in 96 seconds via the
Crowdcube investment platform. On 15 May 2016, Monzo was named the 59th top startup in Startups.co.uk's annual Startups 100 ranking. On 13 June 2016, a company blog post announced that the "Mondo"
trademark had been legally challenged by an undisclosed company with a similar name. As a result, a naming suggestion contest was organised and the new name, "Monzo", was registered at
Companies House under the legal name "
Monzo Bank Ltd" in August 2016. On 16 May 2017, Monzo announced that over £250 million had been spent through its prepaid card, between 200,000 customers.
2017–present: Scaling up In April 2017, Monzo was granted its full
banking licence by the
Prudential Regulation Authority and the
Financial Conduct Authority, having previously operated under a restricted banking licence. The full licence allowed Monzo to provide its customers with current accounts, who up until that point were only able to be offered pre-paid debit cards. Monzo's full current account was launched in October 2017, with its pre-paid card users being asked to move to its new current account. In August 2019, the company announced that it had inadvertently logged 480,000 customer
personal identification numbers, making them accessible to Monzo's internal team of engineers. The issue arose because PINs were transmitted in the
query string of a
HTTPS request. That month the company also launched its loan products for customers. In March 2020, Monzo announced the creation of two business bank accounts for sole traders and small-to-medium sized businesses. This was followed by Monzo's first loan products for its personal current account customers in April 2020. In May 2020, Blomfield announced that he was moving from CEO to president of the company and TS Anil would become the company's CEO. He left the company in January 2021, citing personal pressures heightened by the
coronavirus pandemic among other reasons. In March 2023, the company announced that it had become profitable for the first time. The following year, Monzo was named to the 2024
CNBC Disruptor 50 list. Monzo reported its first annual profit of £15.4 million for the year ending March 2024, compared to a £116.3 million loss the previous year. The company also announced to open an office in Ireland to expand into Europe. Revenue more than doubled to £514.4 million due to increased lending and savings products, though provisions for loan defaults nearly doubled to £204 million. On 30 October 2025, Monzo announced that its CEO T. S. Anil will be stepping down from the position, after serving in that position for nearly 5 years. In December 2025, it was announced that Monzo had agreed to acquire the online
mortgage broker Habito, which at that time employed 100 people. The transaction, subject to regulatory approval and expected to complete in spring 2026, aimed to integrate mortgage advice and broking services directly into Monzo’s mobile banking platform. The company also received a full banking licence from the
Central Bank of Ireland and the
European Central Bank, enabling expansion into Ireland with personal and business accounts.
U.S. expansion Monzo announced on 13 June 2019 that it would begin offering services in the
United States. The company said that it would distribute about 2,000 debit cards to prospective members who attended events it held in major U.S. cities like Los Angeles, San Francisco and New York City. In February 2021, Monzo announced Carol Nelson as the new US CEO, taking over from TS Anil who became Monzo's global CEO after temporarily holding both titles. After it was told by US regulators it was unlikely to be approved for a banking licence, Monzo announced that it had withdrawn its banking licence application in October 2021. Shortly after, Carol Nelson stepped down as US CEO. Monzo US exited beta and was fully launched on 1 February 2022. Without a US banking license, Monzo operates in the US market through a partnership with Ohio-based Sutton Bank. On 31 March 2026, Monzo announced that it would be exiting the US market. == Fundraising ==
