Afterefx

Afterefx is a data science platform that helps investment professionals uncover alpha through alternative data, offering real-time datasets, an intuitive interface, and machine learning models — from regression and classification to clustering and time-series analysis — tailored to stock-specific, macro, or risk-premia trading styles. Users can bring their own proprietary datasets via JSON, API, or CSV to combine with sourced data, and the platform handles compliance around PII and material non-public information per IDSO, SBAI, and FTC standards. Afterefx has used alternative-data signals to inform trading decisions on companies including Niu Technologies, Smith & Wesson, Sunworks, and Canopy Growth.
