London start-up Frank has emerged from stealth with plans to test an AI-powered money app with 1,000 founding members before the end of 2026, ahead of a full public launch in 2027. The company is raising £3m from angel investors to fund its launch, with a product designed to suggest ways to manage money without moving it unless the customer explicitly approves.
Founded in 2025 by Derek Mayne, Frank employs 11 people and has so far been financed by its founder. Its chief executive is Erica Katsambis, formerly vice-president of sales and partnerships at embedded finance company Railsr.
The company disclosed its plans on 6 November. Its proposed platform brings together a current account, mobile wallets, a debit card, savings pots and a conversational AI assistant, aimed at younger consumers.
Suggestions rather than automatic transfers
Frank describes its approach as agentic finance, a model in which software can help manage a customer’s finances rather than simply display balances and transactions. In Frank’s case, the distinction between suggesting an action and carrying it out is central to the proposed service.
According to Katsambis, the assistant is designed to lead with observations about spending and prompt users. It will not move money without their explicit approval. That places a stated limit on the assistant’s autonomy, even as the company seeks to make money management more conversational.
The planned app therefore combines familiar financial products with an assistant intended to take a more active role in drawing attention to spending. A current account and debit card would sit alongside wallets and savings pots, with conversation providing another way to engage with the service.
The supplied details do not establish how approval will be requested or recorded. They also do not specify which actions the assistant will be able to propose. Those distinctions matter when assessing how much responsibility a customer would delegate, and how much would remain with them.
Founder funding and a £3m seed target
Frank’s development has been funded by Mayne, and the company is now seeking a £3m seed round from angel investors to pay for its launch. The fundraising is ongoing, rather than a completed investment round.
The move marks a change from founder-backed development towards seeking outside capital. With 11 employees and a limited beta still ahead, Frank remains at an early stage: its public launch is a plan for next year, not an existing service available to everyone.
The £3m target sets out the scale of the financing Frank is seeking, but does not by itself establish wider conditions in the UK fintech funding market. No valuation, investor commitments or closing date for the round have been supplied.
Katsambis brings experience from Railsr, where she worked in sales and partnerships. At Frank, she is leading a company whose proposition depends on younger customers being willing to use a conversational assistant for decisions about their money.
Consent is central to agentic finance
Frank is an early example of a UK start-up developing agentic finance for consumers. Its plans come while regulators and banks are still working out how autonomous agents should operate in retail finance.
The company’s stated requirement for explicit approval addresses one part of that debate: whether software may move money on its own. It does not, on the information available, answer every question about consent, liability or the regulatory permissions needed to provide the planned products.
These are separate issues. Consent concerns what a customer has authorised. Liability concerns who bears responsibility if something goes wrong. Regulatory permissions concern the basis on which financial services are provided. The details supplied do not explain Frank’s arrangements in those areas.
For London, the proposition is a test of whether an AI-led interface can become part of everyday retail finance. Frank’s intention is clear, but customer acceptance and the effectiveness of its approach have yet to be demonstrated through the planned beta.
Founding members to shape the launch
Frank plans to open its limited beta to 1,000 founding members by the end of the year. Their feedback is intended to shape the product before a wider rollout, giving the company a testing stage between private development and public availability.
The next steps are therefore both financial and operational: securing launch funding, opening the beta and using participants’ feedback to refine the app. A full public launch is planned for 2027. For now, Frank has set out the products it wants to combine and the approval boundary it says its assistant will observe.
