The $25 billion traded is a company-reported figure, not a market size. For IMMIX, it is the proof point. The London-based firm, founded in 2019, has evolved from a quantitative hedge fund into a provider of market infrastructure, with a specific focus on a stubborn problem in crypto payments: exchanging non-USD stablecoins. Its bet is that the quantitative trading expertise of its founders can bring predictable, low-latency foreign exchange to a market currently dominated by opaque, manual over-the-counter deals [immix.xyz, retrieved 2024].
From Hedge Fund to Infrastructure
The company's origin story is a classic fintech wedge. Co-founders Andrew Mann and David Twomey, who met while completing computer science PhDs at University College London, were running a quantitative crypto hedge fund. They reportedly spent more than 90% of their time working around infrastructure limitations [Tech Funding News, September 2023]. Their solution was to build their own. The initial product was a low-latency crypto-trading system with execution and market-making functionality, designed for institutional clients like themselves. This foundation in high-frequency trading became the technical core for their current pivot [PERPLEXITY SONAR PRO BRIEF, October 2026].
The Wedge: AI-Native FX for Stablecoins
Today, IMMIX is targeting a specific gap in the growing stablecoin economy. While USD-pegged stablecoins like USDC and USDT have deep liquidity, their euro, pound, or Singapore dollar-pegged counterparts do not. For a payment company in Europe needing to convert customer funds from USDC to EURC, or for an issuer managing reserves across currencies, finding reliable, executable pricing is difficult. IMMIX acts as a principal market maker, using what it calls an "AI-native" approach. Its deep-learning models forecast market states across more than 10,000 instruments, observing over 30 sources for reference prices and flow to provide firm quotes [immix.xyz, retrieved 2024]. Clients can access this liquidity via API, a portal, or request-for-quote systems.
The founding team's pedigree is central to this pitch. Both founders hold doctorates and have front-office experience at major trading firms.
| Founder | Role | Key Prior Experience |
|---|---|---|
| Andrew Mann, PhD | Co-Founder | Quantitative researcher at Morgan Stanley, DV Trading, and Virtu Financial [PERPLEXITY SONAR PRO BRIEF, October 2026]. |
| David Twomey, PhD | Co-Founder | Began career at J.P. Morgan; later consulted for hedge funds on crypto trading and analysis [PERPLEXITY SONAR PRO BRIEF, October 2026]. |
This background is a direct answer to the risk and complexity of the business. They are not building a consumer app; they are selling institutional-grade reliability, citing 99.99% uptime and the capacity for 3 million messages per second [immix.xyz, retrieved 2024].
The Capital and the Counter-Bet
Investors have backed the technical thesis across two seed rounds. A $2.7 million round in September 2023 was led by MassMutual Ventures, with participation from Ripple Ventures [Tech Funding News, September 2023]. A further $3.5 million was announced in October 2026, with Crane Venture Partners, crypto exchange BTSE, and Portfolio Ventures joining the cap table [GlobeNewswire, October 2026]. The total disclosed funding sits at $6.2 million.
The capital underscores the opportunity, but the counter-bet is clear. IMMIX must prove that a niche, principal trading model can scale to become the default infrastructure layer, competing not just with other market makers but with the entrenched habit of bilateral OTC deals. Its success hinges on a few critical factors:
- Liquidity begets liquidity. The firm must attract enough order flow from payment companies and issuers to provide consistently tight spreads, creating a virtuous cycle.
- Regulatory navigation. Operating as a principal across multiple jurisdictions, especially with stablecoins, invites scrutiny. The team's traditional finance experience may be an asset here.
- Customer concentration. The publicly available record does not name specific paying customers. The next twelve months will be about converting target users like "global stablecoin-payment businesses" into named, referenceable clients [GlobeNewswire, October 2026].
For now, the bet rests on the team's quant pedigree and the $6.2 million from backers like MassMutual Ventures and Crane Venture Partners. The forward question is whether the infrastructure built to solve their own trading problems can become the rails for a new class of cross-border payments. Can a London-based team of PhDs convince the world's payment firms to trust their algorithms over a phone call to a broker?
