ReviewSignal turns consumer reviews into institutional research intelligence. We built the platform we wished existed when we were on the buy side.
Simon brings a background in quantitative analysis and alternative data to ReviewSignal. Frustrated by the lack of granular consumer sentiment tools available to research teams, he set out to build a platform that could process reviews across multiple sources and deliver structured signals in the language investors actually use.
Prior to founding ReviewSignal, Simon worked at the intersection of data science and financial markets, developing proprietary models for consumer behavior prediction and NLP-based signal extraction.
“Transform consumer reviews into desk-ready trading intelligence”
We publish our methodology. MiniLM embeddings, Isolation Forest, Welford's algorithm, propagation logic, and export rules. No black boxes, no proprietary mystery scores. Clients know exactly how every signal is generated.
Zero fake data. We never fabricate, interpolate, or smooth numbers to look better. If a data point is missing, it stays NULL. Every review, every rating, every sentiment score traces back to a real source.
Our reports are structured for institutional reading, not blog-style commentary. Outputs are designed for portfolio managers and research teams that need a disciplined operating document, not a marketing deck.
