Company profile
researched Aug 2026ChartIQ develops a JavaScript charting library and W3C-standard web component framework used to display time-series data such as stock quotes, financial term structures such as interest rate yield curves, and free-form x/y data in web and mobile applications. The library supports interactive navigation including panning and zooming, an extensive set of drawing tools, a suite of technical indicators, multi-panel views with drag-and-drop configuration, Section 508 compliance and internationalization. It requires no external libraries and is compatible with React, Angular and Vue, with published SDKs, sample templates, GitHub projects for Angular, React, Vue, iOS and Android, and a command line interface.
Beyond core charting, the product line includes plug-ins and modules such as CrossPlot/cross sections, term structure charts, low-frequency data support, reference data, SignalIQ event indicators, time span events, Trade From Chart, CompactChart, and chart explainer/conversation features described as AI-ready. The library integrates with static data, quotefeeds and streaming asynchronous data feeds, and ships end-user documentation including a User Guide, Chart Styles and Types Guide and Studies Guide. ChartIQ has provided financial charting and data visualization software to banks, brokerages, financial portals, trading platforms and research/analytics providers, and offers demonstrations of its charts running on S&P Market Intelligence datasets.
ChartIQ was operated as one of two business units of Cosaic (formerly named ChartIQ, later Finsemble Inc.), alongside the Finsemble desktop interoperability platform. In December 2022 the ChartIQ charting business was sold to S&P Global Market Intelligence, while the Finsemble interoperability business was spun off as a standalone company under the original founders.
Business model
ChartIQ licenses its charting library and SDK to financial institutions and software vendors for embedding into their own web, mobile and desktop applications; following the acquisition, S&P Global licenses the ChartIQ charting packages both standalone and bundled within integrated products such as S&P Capital IQ Pro and Markit Digital.
Traction
The company reported 50 employees globally and more than $20 million raised as of the February 2019 Series B. It expanded into cryptocurrency markets with a crypto-specific analysis and trading toolkit and partnerships with exchanges including Coinone, Bitstamp and Bittrex, with market depth charts streaming price, volume and order book data from tens of crypto exchanges.
Latest developments
S&P Global Market Intelligence signed the acquisition of ChartIQ on December 23, 2022 and closed it on January 1, 2023 for undisclosed terms, adding ChartIQ visualization to the S&P Capital IQ Pro platform, Markit Digital and other workflow solutions, including beta charting pages incorporating text analytics. At the same time, former parent Cosaic spun off Finsemble as a standalone desktop interoperability business with new funding from Citi North America, Illuminate Financial Management, Digital+ Partners, AFG Partners and the two founders, and the Cosaic brand was retired.
▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies
Market position
ChartIQ has been described as an HTML5-based financial charting provider serving banks, brokerages, financial portals, trading platforms and research and analytics providers; at the time of the 2019 Series B an investor characterized it as a mature, revenue-producing company positioned for continued leadership in an expanding market. S&P Global Market Intelligence acquired it to strengthen the charting capabilities of its Capital IQ Pro desktop workstation.
The library is positioned around highly interactive charting — fast panning and zooming, user-added studies and comparison symbols, and rapid symbol switching — with no external library dependencies, framework-agnostic compatibility, a W3C web components UI framework, Section 508 accessibility compliance, and the ability to combine vendor-supplied data with proprietary content, alternative datasets or analytics.
Technology
The core product is an ES5-based JavaScript charting engine with an ES6 web components UI layer supporting Web Components Version 1, designed to run on current release versions of major browsers on Windows, macOS, Android and iOS. It requires no external dependencies, works with React, Angular and Vue, supports module bundlers and tree shaking, and offers iOS and Android SDKs plus WebView/container integration. Features include chart styles (line, candle, mountain and others), aggregation-based chart types (Heikin Ashi, Kagi, Point & Figure), CSS and programmatic styling, API injections, custom studies, markers, localization and time zone handling, and data integration via static data, quotefeeds and streaming feeds.
Go-to-market
The company sells business-to-business software licenses to financial firms and platform vendors, supported by developer-facing SDK documentation, tutorials, JSFiddles, GitHub sample projects, demo sites and prototype data integrations (for example a demo powered by S&P Market Intelligence datasets) used to show product capabilities to prospective clients.
Banks, brokerages, financial portals, trading platforms, research and analytics providers, cryptocurrency exchanges and trading firms, and application developers embedding charts in web, mobile and desktop products.
Geography
Headquartered in Charlottesville, Virginia, United States, with employees globally and documentation available in English and Chinese.
History
The company was founded in Charlottesville, Virginia, with Finance Magnates and Seedtable citing a 2012 founding by Dan Schleifer, Megan Read and Terry Thorsen. It raised a $17.4 million Series B in February 2019, by which point it reported having raised over $20 million since founding and employed 50 people globally. The business later operated under the name Cosaic, encompassing both the ChartIQ visualization unit and the Finsemble desktop interoperability platform. In December 2022 Cosaic agreed to sell ChartIQ to S&P Global Market Intelligence, closing January 1, 2023, and simultaneously spun off Finsemble as a standalone company backed by a new funding round; the Cosaic brand was retired.
Risks & controversies
