UK banking technology provider Thought Machine has reached $100 million in annual recurring revenue, CEO Paul Taylor told Sifted, setting the stage for a potential initial public offering once the figure doubles to $200 million. The company's Vault Core platform, which lets banks replace legacy mainframes with cloud-native infrastructure, now counts Lloyds Banking Group, Standard Chartered, SEB, and Atom Bank among its clients.

Revenue grew roughly 19% in the most recent period, though the absolute figure remains modest relative to the $2.7 billion valuation the company commanded after a $229 million funding round in 2021. That round, led by Molten Ventures and British Patient Capital, valued the firm at nearly 27x ARR — a multiple that has compressed across the fintech sector as public-market investors prioritize profitability over growth.

Taylor said the path to $200 million ARR depends on expanding existing contracts and landing new Tier 1 banks in North America and Asia. The company employs 570 people across London, Singapore, New York, and Sydney. With $9.7 billion in total client deposits now running on its platform, Thought Machine argues its revenue base is stickier than typical SaaS models.

The IPO timeline remains fluid. Taylor acknowledged that market conditions, not just revenue thresholds, will dictate the listing decision. Competitors Mambu and 10x Banking have also signaled public-market ambitions, but none have yet filed. For investors, the key metric is whether Thought Machine can sustain enterprise sales cycles of 18–24 months while keeping net revenue retention above 120%.
