IMMIX Raises £2.6m to Make Cross-Border Stablecoin Payments Cheaper

Moving money internationally is becoming easier, but converting it between currencies remains a costly problem for payment providers. London fintech startup IMMIX has raised £2.6 million to tackle that challenge, using AI-powered pricing and institutional trading infrastructure to make stablecoin conversions more efficient.

Announced on 8 October 2026, the funding came from Crane Venture Partners, BTSE and Portfolio Ventures. The company plans to use the capital to improve its pricing technology, expand liquidity and grow its network of payment partners.

The problem goes beyond moving money

Stablecoins are digital assets designed to maintain a relatively stable value, often by tracking a traditional currency such as the US dollar. They can move between digital wallets around the clock, making them attractive for international payments.

But sending money is only part of the process. Businesses still need to convert funds into the currencies their customers require.

That becomes more complicated outside the US dollar, where trading liquidity can be fragmented and fewer buyers and sellers are available. A conversion may require several separate foreign exchange trades, each adding costs and potentially tying up funds with multiple providers.

For payment companies handling thousands of transactions, those additional costs can eat into already tight margins.

IMMIX is building infrastructure to reduce that friction, particularly for currencies beyond the dollar.

AI meets institutional trading

Founded by Dr Andrew Mann and Dr David Twomey, both computer science PhD graduates from University College London, IMMIX combines deep-learning models with institutional-grade trading systems.

Its technology forecasts market conditions across thousands of instruments to help price and execute stablecoin conversions. According to the company, its systems have processed more than $25 billion in customer trading volume since 2024.

The founders bring experience from financial institutions including Morgan Stanley, JPMorgan and Virtu Financial. That background matters in a market where pricing accuracy, execution speed and reliable liquidity can make a significant difference.

Rather than targeting consumers directly, IMMIX works with payment service providers, money transfer operators, stablecoin issuers and trading platforms.

Why this funding matters

For fintech founders, IMMIX offers an example of a startup targeting the infrastructure behind an emerging market rather than competing for consumer attention.

Stablecoins may attract headlines, but their wider adoption depends on the less visible systems that make transactions practical, affordable and reliable.

The funding also highlights the role of specialist venture investors in backing technically demanding businesses with experienced teams and an identifiable commercial problem.

IMMIX still needs to expand its partnerships and demonstrate that its technology can deliver lasting advantages across more currencies and markets. But its existing trading volume gives investors a concrete starting point as it develops its next stage of growth.
