Ancestry.com Inc.

Mark and Darlene Castelli launched Ancestry in 1983 to publish family history guides before the internet era. Paul Allen acquired the struggling publisher in 1997 and pivoted the business toward digitizing historical records. This strategic shift turned a small Utah operation into a global data powerhouse that now hosts over 1.3 billion records.

The company operates on a dual revenue model combining subscription access to genealogical databases with direct-to-consumer DNA testing kits. Membership tiers range from roughly $24.99 to $59.99 monthly depending on features like tree building limits or health insights. While Ancestry maintains a commanding lead in the U.S., it faces competition from MyHeritage, FamilySearch, and 23andMe as it expands into international markets with localized sites.

Blackstone Inc. took control of the company in August 2020 by purchasing an 80% stake for $4.7 billion. The private equity firm later acquired full ownership and has since explored options including a potential IPO or sale with valuations reaching $10 billion. Howard Hochhauser served as CEO during this transition period, guiding the organization through significant debt refinancing efforts in mid-2026. [edit]
