Prattle Analytics was an innovative investment research firm specializing in quantifying market-moving communications using proprietary Natural Language Processing (NLP) and Machine Learning (ML) technologies. Their core product, 'Portfolio Sentiment,' provided predictive analytics by analyzing official statements, earnings calls, and central bank commentary to generate objective sentiment scores. This enabled institutional investors to make more informed decisions by understanding the subtle nuances in language that impact asset prices. Prattle was acquired by Liquidnet in 2019, which was subsequently acquired by TP ICAP in 2021, integrating Prattle's technology into broader financial market solutions.
Served as the main hub for research, development of its NLP and ML algorithms, product creation, and core business operations.
Likely situated within the Cortex Innovation Community, known for its modern facilities, collaborative environment, and proximity to other tech companies and research institutions.
As a fintech startup, the work culture was characterized by innovation, a fast-paced environment, and a strong focus on data science, engineering, and collaborative problem-solving to disrupt traditional financial analytics.
The St. Louis headquarters was crucial for fostering Prattle's initial growth, developing its core technology, and establishing its reputation in the fintech space before its acquisition.

Its technology analyzed communications from global central banks and corporations, indicating a global data coverage strategy.
