IMMIX Raises $3.5M Seed for AI-Powered Stablecoin FX Infrastructure

IMMIX Secures $3.5M Seed Round

IMMIX, a London-based AI-native trading firm building FX infrastructure for stablecoin payments beyond the US dollar, has raised $3.5 million in seed funding. The round was announced on October 8, 2026.

Investors participating in the round include Portfolio Ventures, Crane Venture Partners and BTSE. No lead investor was disclosed.

What IMMIX Does

IMMIX operates at the intersection of two growing markets: stablecoin payments and foreign exchange. The company builds FX infrastructure designed to support stablecoin payments beyond the US dollar, combining an AI-powered pricing engine with institutional liquidity infrastructure.

The core function of the platform is to price and execute stablecoin conversions for payment firms, stablecoin issuers and trading venues. Rather than routing a transaction through multiple FX legs, IMMIX's system collapses those legs into a single directly priced transaction.

That structure matters for payment firms and issuers that need to move value between stablecoins and fiat currencies outside the dollar bloc. Multi-leg FX conversions introduce additional spread, latency and operational complexity. A single directly priced transaction can reduce those frictions, which is the value proposition IMMIX is bringing to institutional counterparties.

Traction

According to the company, its systems have processed more than $25 billion in customer trading volume since 2024. That figure provides a meaningful signal of institutional adoption for a company still at the seed stage.

Founding Team

IMMIX was founded by Dr Andrew Mann and Dr David Twomey. Both are UCL Computer Science PhDs with quantitative trading backgrounds — a combination that aligns with the company's positioning as an AI-native trading firm rather than a purely software infrastructure provider.

The quantitative trading background of the founders is relevant to the business model: pricing and executing FX conversions at institutional scale requires both technical infrastructure and trading expertise, particularly when the goal is to compress multiple FX legs into a single price.

Round Details

• Announcement date: October 8, 2026
• Investors: Portfolio Ventures, Crane Venture Partners, BTSE
• Lead investor: Not disclosed

Why This Round Matters

The stablecoin payments market has expanded rapidly, but much of the infrastructure focus has centered on dollar-denominated stablecoins. IMMIX is targeting a specific gap: FX infrastructure for stablecoin payments beyond the US dollar.

That focus places the company in a segment where demand is driven by payment firms, stablecoin issuers and trading venues that need to convert between stablecoins and non-USD currencies. The company's reported $25 billion in processed volume since 2024 suggests it has already established relationships with institutional counterparties in this segment.

The presence of BTSE among the investors is notable given its position in the digital asset trading space, while Portfolio Ventures and Crane Venture Partners bring venture backing to the round.

What to Watch

At the seed stage, the key questions for IMMIX center on scaling. The company has demonstrated volume through its systems, and the new capital will presumably support expansion of its pricing engine and liquidity infrastructure.

Competition in stablecoin payments infrastructure is intensifying, with numerous firms targeting cross-border payment flows and currency conversion. IMMIX's differentiation rests on its AI-powered pricing engine, its single-transaction approach to multi-leg FX, and its founders' quantitative trading backgrounds.

For observers tracking the stablecoin infrastructure market, this seed round adds another data point to the trend of venture capital flowing toward the plumbing that supports stablecoin payments — particularly in segments outside the dominant dollar-denominated flow.

Summary

IMMIX has raised $3.5 million in seed funding, with Portfolio Ventures, Crane Venture Partners and BTSE participating. The London-based company builds AI-powered FX infrastructure for stablecoin payments beyond the US dollar, and reports more than $25 billion in customer trading volume processed since 2024.
