The footer reads "© sightengine 2013 - 2026", which dates the copyright, not the founding; the French company register (recherche-entreprises.api.gouv.fr) lists KOZELO (SIREN 510113509) created 2009-02-01, which may predate the product. sightengine.com/about, /contact and /terms state no founding year.
