Empirasign is the leading provider of secondary market trading data for the US and UK Fixed Income and Structured Products markets. Our web-based real-time database offers the most exhaustive data set of secondary market activity for all ABS, MBS, & CMBS sub-sectors, with BWIC history dating as far back as 2010.

We use proprietary Natural Language Processing technology to index BWICs (price talk and trade color) and dealer benchmark runs (bids, offers, and markets) contributed by our comprehensive network of market participants. Clients access this information via our browser-based web application featuring advanced search capabilities, powerful metadata reports, automated portfolio monitoring, and data-driven sales and marketing tools. We also offer custom in-house tools via our REST-based API, and RPC-based parsing solutions tailored to your firm’s needs.

We serve both front and middle-office professionals for the sell side and buy side. Other core markets include evaluated pricing, auditing, and CRM companies. Since 2009, we have remained focused on delivering the most comprehensive and cost-effective view of the secondary markets available anywhere.

We are headquartered in Midtown Manhattan and maintain a Data Quality Assurance and Customer Service facility in central London.
