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 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.

Values

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.

Institutional Rigor

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.
