Symphony

Founded in 2014 by a consortium of major Wall Street firms, Symphony began as a secure cross-firm messaging platform. It has since expanded into a broader financial-markets technology company serving institutions across global finance.

Symphony’s products span four connected platforms: Messaging, Voice, Directory and Analytics. They support encrypted communications, trader voice, market-participant discovery, workflow integrations, data analysis and AI-enabled automation, with controls designed for regulated financial institutions.

Its strongest position is in replacing fragmented or non-compliant communication channels with auditable infrastructure that connects banks, asset managers, brokers and other market participants. The platform also has a substantial developer and partner ecosystem, including APIs, bots and integrations with enterprise workflow and market-data tools.
