About this data
Techmap scans millions of job ads from company career pages and job portals every month and extracts the technologies they mention. A company is listed here if it published at least one job ad for Cologne (incl. surroundings) in the last months that mentions Linux (numbers per year are extrapolated; job ads without other technologies are ignored, as the extraction of single terms like "Swift" is not reliable). Job ads of recruiting agencies and duplicates of the same job ad on several portals are not counted. See all technologies used in Cologne or Linux companies worldwide.
