A New Trading Market Plans to Transcend Traditional Value Exchange 

New York, New York – October 14, 2025

Mosaic Platforms announced the completion of its strategic investment round and anticipated launch of its US equity Alternative Trading System (ATS) in the first quarter of 2026. 

Founded by John Cosenza and Joe Wald, Mosaic Platforms is developing a unique market model that will evolve market execution.

The initial investment round included strategic investments from Guggenheim Securities and RBC. 

“Completing our seed investment round is a critical first step in accelerating our technology development, business operations, and go-to-market strategy.  We are grateful to all our investors, including our strategic investors, Guggenheim Securities and RBC for their commitment to Mosaic’s vision and support for market innovation”, said Joe Wald.

“We are committed to investing in our equity trading product and helping our clients navigate a complex market structure,” said David Margulies, Managing Director – Electronic Solutions at Guggenheim Securities.  “We believe Mosaic’s innovative concept for a new market center model can help improve performance for liquidity originators.”

“We have studied the impact of rising market quality challenges, and we believe Mosaic is strategically positioned to help improve market quality and overall performance,” said Doug Crofton, head of US Cash Equities Execution at RBC Capital Markets. “RBC Capital Markets has a proud history of market structure-related innovations and investments, including through in-house developed technology solutions, intended to support best execution and more fair and efficient markets. We look forward to being an early adopter once the venue is live.”

Earlier in the year, Mosaic selected Nasdaq Eqlipse Trading (formerly Ocean) as its technology partner.  Nasdaq is also a leading provider of market infrastructure and surveillance services, empowering operators to innovate and differentiate on market model, user features and client service. 

“For innovative players like Mosaic entering the market, leveraging Nasdaq’s battle-tested market infrastructure allows new entrants to focus investments where they truly differentiate,” said Magnus Haglind, Head of Capital Markets Technology at Nasdaq. 

Mosaic Platforms has already begun assembling an experienced team of industry practitioners and operators to unlock the vision of a unified trading ecosystem.  

“People are the success multiplier.  Building high performing teams to help clients achieve their objectives has been a blueprint for Joe and I throughout our careers.  We are excited to begin the journey of creating shared value between diverse market participants,” said John Cosenza.
