SuperSaaS is an Amsterdam-headquartered Dutch online appointment-scheduling platform operated by SuperSaaS B.V. (Strawinskylaan 6, 1077 XZ Amsterdam) and founded in 2007 by Jan M. Faber. The company has reached 205,000+ businesses on the platform across 60 countries and 35 UI languages, and remains unfunded (no PE, no VC, no parent), making it one of the longest-running founder-controlled EU SaaS in the directory. The product covers self-service appointment booking for service businesses (yoga / fitness studios, salons, clinics, equipment rentals, classroom bookings, language-school timetables), reminders by email and SMS, payments through PayPal and Stripe, calendar sync, and integrations.
For an EU-sovereignty audit SuperSaaS is structurally clean at the ownership layer: Dutch B.V., founder-controlled, no outside capital. Where the listing weakens is at the procurement-documentation layer: the dedicated privacy-policy URL did not resolve at audit, a named sub-processors list is not publicly indexed, and the underlying hosting provider for booking-data storage is not disclosed on accessible public pages. The product takes no transaction fees (PayPal / Stripe / other payment processors charge their fees directly), and the free tier covers up to 50 appointments with SuperSaaS-branded advertising; paid tiers scale by appointment volume from ~US$8/month and remove advertising.
Best fit: long-tail service-business segments (yoga studios, salons, dentists, driving instructors, equipment rentals, language schools, sports clubs) that need multilingual booking pages; SuperSaaS's 35-language coverage is unusually broad for the category and aligns with niche-language EU markets that Calendly and Acuity under-serve. Procurement-grade buyers requiring a contract-grade DPA, named sub-processors, and explicit hosting commitment should request these directly from SuperSaaS before signing; alternatively look at Cal.com (open-source self-host) or Reservio (Czech B2C booking) in this category.
