Jacqueline Sigler, Principal
JS Advisory appears to be a consulting firm offering cross-industry expertise and advisory services, as indicated by the German-language site's emphasis on 'Beratung mit Substanz' (consulting with substance) and 'Branchenübergreifende Kompetenz' (cross-industry competence). The firm's name and the principal's initials align with the LLC filing, and the site presents a small-shop, professional advisory profile consistent with a single-location business.
