Marble secures $11M seed funding led by Polychain Capital

Marble, a new institutional capital markets firm, launched on November 10, 2026 with an $11 million seed round led by Polychain Capital.

Other backers in the round include Maven 11, Ripple, Susquehanna Crypto, Lattice, Blockwall Ventures, and a group of AI-focused angel investors.

Who is behind Marble

The company is run by two co-CEOs with long institutional resumes. Matt Ballensweig previously served as Global Head of Trading at BitGo.

Leon Marshall was formerly CEO of Galaxy Digital Europe.

Polychain Partner Angelo Goepel pointed to the founders’ track record of scaling institutional trading and lending across different market cycles.

Goepel also highlighted what he sees as a significant opportunity where frontier-market trading meets AI infrastructure credit.

Two business lines, one balance sheet of ambition

Marble is organized around two main divisions: Marble Compute and Marble Markets.

Marble Compute focuses on building institutional private credit infrastructure for AI-related needs. The idea is to connect lenders with neocloud providers and GPU operators.

Neoclouds are newer cloud providers built specifically around GPU compute for AI workloads.

Marble Markets is the trading side of the house. It is set to offer a platform spanning digital assets, real-world assets (RWA), prediction markets, and computing capacity.

Timeline and use of funds

Marble has not launched products yet. Initial product launches are anticipated in early 2027.

Digital asset trading is slated to begin in January 2027, which would make it the first live piece of the Marble Markets offering.

The $11 million will go toward expanding the team and building out technology. That includes the trading and custody systems the company needs to serve institutional clients.
