Simon Daniel

Founder & CEO
Frankfurt am Main, Germany

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 practical research language.

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.

What We Stand For

Radical Transparency

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.

Data Integrity First

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.

Research Rigor

Our reports are structured for disciplined reading, not blog-style commentary. Outputs are designed for teams that need a clear operating document, not a marketing deck.
