Mosaic Platforms

What Mosaic Platforms does

Mosaic Platforms, Inc. is a privately held technology holding company founded in 2024 and headquartered at 875 Washington Street, 4th Floor, New York, NY 10014. Through its wholly owned subsidiary Mosaic ATS, LLC—a FINRA and SIPC member firm—the company operates Mosaic ATS, a US equity Alternative Trading System targeted exclusively at institutional and professional clients. The company publicly states on its website that the site is intended only for institutional and professional clients, with retail customer use prohibited.

Mosaic's core product is the Mosaic ATS, built around its proprietary MERIT scoring and rating system, which the company describes as a first-of-its-kind technology powering a new market interaction model that transcends traditional matching systems focused on the final milliseconds of trading. The platform integrates Nasdaq Eqlipse Trading (formerly Ocean) as its core technology partner for market infrastructure and surveillance, and emphasizes trading compatibility and footprint confidentiality as design pillars intended to let diverse market participants share value within a unified trading ecosystem.

Mosaic's business model is transaction-fee based: it charges for trade execution on its ATS rather than running a subscription or per-seat pricing model. Distribution is exclusively enterprise-direct to institutional and professional trading firms; the go-to-market leverages strategic investors Guggenheim Securities and RBC Capital Markets, both of which participated in Mosaic's October 2025 strategic seed round and committed to early adoption of the venue. Mosaic completed its seed round on October 14, 2025, formally announced its planned Q1 2026 US equity ATS launch, and publicly confirmed delivery of its MERIT-driven market on April 28, 2026. The leadership team is anchored by co-founders John Cosenza (25+ years; former Head of Electronic Trading in the Americas at Goldman Sachs) and Joe Wald (30+ years; co-founder of EdgeTrade and Clearpool, both acquired by Knight Capital and BMO respectively), with senior hires from Seven Eight Capital, RBC Capital Markets, Guggenheim Securities, Virtu Financial, ITG, and Lehman Brothers.

Direct peers

• IEX: IEX operates IEX Exchange and IEX ATS, a US equity alternative trading system designed around different execution-quality principles (e.g., D-Limit, speed bumps) — directly comparable to Mosaic's stated thesis of transcending traditional final-millisecond matching.
• Instinet: Instinet operates US equity ATSs (e.g., CBX, ITG POSIT) historically focused on institutional agency trading and execution quality — closely comparable to Mosaic's institutional, performance-sensitive positioning.
• Liquidnet: Liquidnet operates institutional block-trading ATSs and crossing networks for US equities and global equities — a comparable for Mosaic's commitment to institutional-only access and footprint/confidentiality-oriented design principles.
• MEMX (Members Exchange): MEMX is a newer US equities exchange and ATS built to challenge legacy market structure on fees and execution quality — directly comparable as a recent, electronic-trading-focused entrant competing for institutional flow.
• MIAX: MIAX operates US equity exchanges and ATS/electronic-trading venues and has expanded into US equities — a direct comparable as a multi-asset trading infrastructure operator with retail-plus-institutional access models.
• BIDS Trading: BIDS Trading runs one of the largest US block-trading ATSs with deep institutional participation; its emphasis on trading-compatibility design and block liquidity placement makes it a core comparable for Mosaic's institutional-targeted ATS model (and a board venue where Mosaic's co-founder John Cosenza has previously served).

Emerging players

• Blue Ocean Technologies: Blue Ocean operates an alternative US equities trading session (overnight/pre-market matching) targeting differentiated execution windows — a comparable as a smaller, niche electronic-trading venue attempting to redefine when/how US equities trade, similar in spirit to Mosaic's 'new interaction model' thesis.

Broad incumbents

• Virtu Financial: Virtu Financial operates multiple US equity ATSs and crossing venues (e.g., POSIT, Sigma X, Pipeline) in addition to its wholesale market-making business — a broad incumbent and aggregator-level comparable for Mosaic's planned single-venue ATS.
• Nasdaq: Nasdaq is both Mosaic's chosen technology partner (Eqlipse Trading) and a competitor operating multiple US equity exchanges/ATSs (e.g., BX, PSX, INET) — a structurally comparable incumbent that could also become a route-distribution competitor.
• Cboe Global Markets: Cboe operates multiple US equity exchanges and ATSs (EDGX, EDGA, BZX) competing on execution quality and fee economics — directly comparable as a new-venue challenger template for Mosaic and the broader ATS competitive set.
