  • Comment: Resubmitting after the October 2026 decline. Since then the draft has gained independent, secondary coverage of the subject from three unrelated publishers: two full-page newspaper profiles (Gießener Allgemeine Zeitung, 16 Oct 2026, with online version; Wetzlarer Neue Zeitung, 29 Oct 2026, p. 15), a second WirtschaftsWoche article (10 Feb 2005) alongside the 2004 profile, and an interview-based article in the Swedish business paper Realtid (23 May 2017). All claims about career stations are now cited to these sources rather than to primary material. Declared conflict of interest: I am the subject of the article.

Reiner Kraft is a German computer scientist and entrepreneur known for his work on search technology at IBM Research and Yahoo!. He was named to the MIT Technology Review list of top innovators under 35 (TR100) in 2002.[1] Born in Gießen, he returned to the region after more than two decades in the United States and Berlin and co-founded EVER Health GmbH in Lahnau.[2][3]

Early life and education

Kraft was born in Gießen, Germany, and grew up in Münchholzhausen, a district of Wetzlar.[2][3][4] After a banking apprenticeship at the Sparkasse Wetzlar and his Abitur at the Goetheschule in Wetzlar, he studied computer science at the Fachhochschule Gießen-Friedberg (now the Technische Hochschule Mittelhessen) before moving to San Jose, California, in the late 1990s.[2] He received his PhD in computer science from the University of California, Santa Cruz in 2005, advised by Raymie Stata.[5][6]

Career

IBM Research

Kraft first worked for IBM Germany in Frankfurt before moving to California in 1997.[3] From 1997 he worked as a software engineer at IBM's Almaden Research Center in San Jose, California.[4] He co-invented a scheme for distributing large computing tasks over the Internet to many personal computers, for which IBM filed a patent application in 1998, and he created jCentral and xCentral, specialized search engines for Java and XML resources.[1][7] By 2004 he had filed more than 100 patent applications, and IBM had awarded him the title of Master Inventor. WirtschaftsWoche described him at the time as the most prolific inventor in Silicon Valley.[4] Kraft is named as an inventor on more than 110 granted United States patents.[3][8][2]

Yahoo!

Kraft joined Yahoo! in 2004, recruited from IBM, and worked there on search technology for twelve years.[3] Alongside his work at Yahoo!, he taught web engineering at the University of California, Santa Cruz.[3] WirtschaftsWoche credited him with devising Y!Q, a contextual search tool that Yahoo began testing in February 2005.[9] His research there focused on contextual search, including the Y!Q system, which used the content a user was reading to refine web searches.[10][11]

Zalando

In 2016 Kraft moved to Berlin to join the online retailer Zalando, where over two years his team grew from 20 to 70 engineers.[2][3] By 2017 he was vice president of engineering there, where he was responsible for developing technologies including artificial intelligence, machine learning and virtual reality.[12]

Later career

In 2019 Kraft joined the leadership team of Yunar, a loyalty-program app operated by Deutsche Bank subsidiary Ambidexter GmbH, with responsibility for technology and data.[13] In 2025 Kraft co-founded EVER Health GmbH, a health software company based in Lahnau.[14] The company operates a platform for preventive health in which physicians, alternative practitioners and health coaches accompany clients through a mobile app; it includes a rating system for dietary supplements.[2] By late 2026 the company had five employees and its platform was used by around 200 practitioners.[3]
