Company profile
researched Aug 2026Sense Street is a London-headquartered financial technology company that builds natural-language understanding and generative-AI systems for capital markets. Its platform ingests unstructured trader communications — chat and voice negotiations conducted across venues such as Bloomberg, Symphony, ICE and WhatsApp — and converts them into structured, machine-readable market data. The company describes its extraction platform as agnostic to the channel, data format and language in which a trade is conveyed, and states it supports common APIs so clients avoid vendor lock-in.
The product set described on the company website includes an AI-enhanced blotter that captures both executed and non-executed conversation signals, a Quotebook that converts broker conversations into real-time structured market data available via API, and AI-driven workflow automation for complex, multi-party, multi-asset conversations. Coverage is described across FICC — fixed income, currencies and commodities, including physicals and derivatives — with multilingual parsing covering languages including English, Japanese, Mandarin and Spanish. Sense Street says it trains a capital-markets-specific language model on proprietary chat data, verifies outputs with human reviewers, and continuously tunes models to limit performance drift.
Security and data-governance claims are a stated part of the offering: client data is described as never shared or reused, personally identifiable information is anonymised before processing, data is encrypted in transit and at rest with access controls and auditability, and infrastructure is described as aligned with ISO 27001, GDPR, DORA and SOC 2 frameworks. A third-party private-markets database classifies the company as FinTech with verticals spanning financial data, NLP and conversational AI, workflow automation, and compliance and risk.

Market position
Positioned as a purpose-built AI vendor for capital-markets communications rather than a general-purpose AI provider. A third-party database lists ipushpull, VoxSmart and Bloomberg L.P. as the most similar comparable companies.
Stated differentiators include a domain-specific capital-markets LLM trained on proprietary trading chat, platform and asset-class agnosticism, multilingual coverage, capture of non-executed as well as executed conversation signals, human-in-the-loop verification, and enterprise data-sovereignty and compliance commitments.
Technology
Machine-learning-first extraction platform built around a capital-markets language model trained on proprietary chat data, which the company states outperforms general-purpose LLMs on trading-desk workflows such as quote extraction and liquidity mapping. The system ingests conversations from major chat and communications platforms in multiple formats and languages, normalises them into structured outputs, and is claimed to reach over 95% accuracy in live environments with rapid multi-asset deployment. Human reviewers verify outputs and models are tuned continuously.
Go-to-market
Direct enterprise sales to financial institutions, supported by interactive product demos on the company website and API-based integration with existing chat and communications infrastructure.
Capital-markets participants engaged in OTC and voice trading — trading desks, brokers and dealers across fixed income, currencies and commodities, including physical and derivatives desks. Internal records also indicate use at investment bank trading desks and deal rooms.
Geography
Headquartered in London, United Kingdom, with a registered office at 131 Finsbury Pavement, London EC2A 1NT; an earlier registered correspondence address was at Citypoint, 1 Ropemaker Street, London. Directors' places of residence span the United Kingdom, Poland and the United States, and the company states model exposure to chat data from every major trading region.
History
Incorporated 4 March 2019 as a private limited company (number 11857449) under SIC code 62012, business and domestic software development. A third-party database records an accelerator round in March 2019 and a seed round in August 2022. Board changes include the appointment of Maciej Gnutek and Arnaud Bakker in August 2022, Bakker's resignation and Tamara Oprea's appointment in March 2024, and the resignation of company secretary CC Secretaries Limited in November 2025. As of the latest Companies House record the company is Active, with accounts last made up to 31 March 2026 and a confirmation statement dated 3 March 2026.
Risks & controversies
No controversies are reported in the available sources. Source data is inconsistent on basic firmographics: a third-party database lists the founding year as 2018 and total funding of $4.72M without per-round detail, while the UK companies register shows incorporation in 2019. Accuracy, compliance-standard alignment and data-handling claims are company-stated and not independently verified in the sources.
