Speakerbus

What Speakerbus does

Speakerbus is a London-headquartered, privately held provider of mission-critical voice communication platforms built specifically for financial trading environments and adjacent command/defense use cases. Founded in 1984 and operating across offices in the UK, US, Singapore, India, Switzerland, and Malaysia, the company serves over 230 institutions and 50,000+ traders in 70+ countries, with disclosed anchor deployments at firms such as Jones Trading, a Seoul-based world-leading broker, leading energy brokers, global asset managers, Clarksons Platou Futures, ADM Investor Services, and Arbuthnot Securities.

The product portfolio centers on two complementary platforms: QORUS, an on-premises/hybrid critical communications stack comprising endpoints (iTurret, AYRE, ALTO, iD712, SE 708/ZERO8), servers (iCS, iCMS, iWS, iCB), and gateways (iG330, iG334); and Cadence, a cloud-based delivery of the same capabilities with ultra-low latency in private, public, or hybrid cloud architectures on Google Cloud Platform and Microsoft Azure. ARIA provides a browser-based soft client inheriting compliance and recording policies, and Sonance (powered by SteelEye) adds cloud-based compliance oversight. The stack is certified against Avaya Aura and Cisco Unified Communications Manager and integrated with leading compliance recorders (NICE, Red Box, VPI, Liquid Voice, CTI Group).

Revenue is generated through four streams: one-time hardware sales (turrets, speakers, gateways), recurring SaaS/cloud subscriptions (Cadence monthly billing), software support and maintenance contracts, and professional services for deployment and configuration. The company goes to market via direct enterprise field sales, Avaya and Cisco channel partners, and event-driven demand generation at FIA, The Trading Show, DSEi, and INTERPOL World. In 2025, following a liquidation process, all assets of Speakerbus Limited were acquired by comitFS Limited, with the website and operations continuing under the comitFS banner.

• NICE: NICE is a broader enterprise software and compliance vendor whose NICE Trading Recording (NTR) solution is a certified Speakerbus partner. While not a direct turret competitor, NICE's expanding compliance and analytics portfolio overlaps with Speakerbus's Sonance compliance offering.
