ReviewSignal transforms the world's consumer reviews into institutional-grade trading 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, real-time consumer sentiment tools available to institutional investors, he set out to build a platform that could process millions of reviews across multiple sources and deliver actionable 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 institutional-grade trading intelligence”
We publish our methodology. MiniLM embeddings, Isolation Forest, Welford's algorithm, Monte Carlo simulation. 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 read like Goldman Sachs equity research, not blog posts. Every output passes quality gates. We built this for portfolio managers allocating billions, not retail traders looking for tips.
