Prattle

Prattle was an alternative data and NLP analytics company that transformed complex financial communications into real-time, quantitative, tradable signals for institutional investors. Founded as a research automation firm specializing in the analysis of complex market-moving language, Prattle's platform algorithmically mapped linguistic patterns in corporate earnings calls, press releases, and central bank statements to historical stock price movements. Each company received a custom machine-learning lexicon that continuously updated to score new communications and produce sentiment scores indicating expected future performance. Prattle's equities analytics covered 4,000 publicly traded US companies at approximately per stock. The company was acquired by institutional trading network Liquidnet in June 2019 and became part of Liquidnet Investment Analytics.
