In 1965, an engineer in Scotland was given a mundane task with a tricky problem to it - banks wanted to close on Saturdays and still serve customers, but they didn’t know how to solve authentication of the right user. Like the ATM, Mercury is building technology that pushes forward financial interfaces for the long term. Command is Mercury’s LLM-powered financial assistant, launched to all customers in June 2026. It lets users understand their finances and take action in plain language, from asking about cash flow to sending payments, issuing cards, and managing invoices. With the product now in customers’ hands, the work is to evolve it, extend its capabilities, and find recent ways to leverage LLMs to give Mercury customers a more powerful banking* experience.
