This dual-entity structure supports broad regulatory compliance and market coverage. The board of directors includes fintech industry veterans, and the company has attracted significant investment from European venture capital and financial institutions. The platform's valuation fluctuated between £1 billion and £2.5 billion in recent years before the Lloyds acquisition.

Licensing is held under Electronic Money Institution (EMI) status granted by the Financial Conduct Authority in the UK and the Bank of Lithuania.
