What Silc does

SILC, legally organized as SAS SILC by Cassiopée and headquartered in Angoulême, France, is a privately-held language travel and educational services agency founded in 1965, now in its 60th year of operation. The company designs and sells all-inclusive language immersion programs and school trips across 17 destination countries teaching 7 languages, serving four distinct segments: adolescents aged 8-18, students aged 16-25 seeking semester study abroad, adults and educators participating in Erasmus+ funded mobility programs, and French schools organizing group educational travel. The product portfolio covers five core lines — adolescent stays, student semesters, adult/Erasmus+ programs, full-year high school study abroad, and customized school trips — with pricing ranging from approximately €513 for short adult courses to €8,995 for semester programs in New York, and accommodation in host families or collective housing. SILC differentiates through AFNOR NF Service certification under NF EN 14804 (a regulated quality mark for language stay organizers), ATOUT France registration, and a 60-year brand with a 4.4/5 Google rating and 92%+ participant satisfaction.

The technology layer is intentionally light: a website-based booking and brochure-request platform with Microsoft Outlook calendar integration for appointment scheduling, supported by telephone and email sales channels. There is no proprietary software, no mobile application, no API, and no disclosed AI/ML capabilities. SILC's competitive position rests on regulatory certifications, institutional partnerships (Erasmus+ approved organizer status, CNAS preferential-rate partnership for French public-sector beneficiaries, APST financial guarantee), and referral relationships with French schools. Distribution is dual-channel: direct-to-consumer via silc.fr and inside sales for individuals/families, and direct B2B field sales with customized pedagogical proposals for schools and educational institutions. Revenue mechanics are one-time program fees with installment billing (deposits of €600 or 30%, with balance payments tied to departure dates), making each transaction episodic rather than recurring.
