About Prelvox
Data-driven, editorially independent
Tennis statistics, long-form journalism, and transparent methodology. Built in London, grounded in numbers.
Prelvox was founded on a simple premise: tennis produces extraordinary data, and that data deserves extraordinary journalism. Every match generates hundreds of statistical data points -- serve speeds measured to the nearest kilometre per hour, break point conversion rates that reveal a player's composure under pressure, surface-specific win percentages that map the geometry of the court onto the mathematics of results. Most tennis coverage discards this richness in favour of final scores and post-match quotes. We believe the numbers tell deeper, more interesting stories.
Our editorial team combines statistical analysis with long-form storytelling. Every table on this site is wrapped in context: a paragraph before explaining what you are about to see, a paragraph after drawing conclusions from the data. We do not publish tables in isolation, and we do not make predictions.
“A first serve is a hypothesis. The data tells you if it was right.”
Our approach
Prelvox draws on official ATP and WTA tour data, Grand Slam organiser statistics, ITF records, and historical archives spanning 147 years of championship tennis. Every statistic is verified against at least two independent sources before publication.
We supplement official data with odds-market data from UKGC-licensed operators for contextual analysis. These commercial partnerships fund the platform but exert no influence over editorial content, statistical methodology, or publication decisions.
Our methodology documentation is published on the Data Lab page. We believe transparency about how numbers are collected and processed is as important as the numbers themselves.
