GEDmatch is a free DNA comparison and analysis website for people who have tested their autosomal DNA using a direct-to-consumer genetic testing company, such as 23andMe, or have a custom file from other sources. Testers download their DNA data file from the testing company, and then upload it to GEDmatch. GEDmatch processes the file, adds it to a genealogical database, and provides applications for matching and further analysis. Because GEDmatch aggregates files from all testing companies, your potential for matches is greater. Curtis Rogers founded GEDmatch in 2010 with his co-founder John Olson and a small group of volunteers. Verogen purchased GEDmatch in 2019, continuing the founders' vision for a consumer genealogy site with a commitment to infrastructure, privacy, and security.
