What porta mundi AG does

porta mundi AG is a privately held Swiss tutoring and education services company founded circa 2021 and headquartered in Zürich (legal entity: Aktiengesellschaft, CHE-477.802.137), with its primary course location in Erlenbach ZH at Seestrasse 141. The company specializes in preparing students in the Canton of Zürich for the gymnasium entrance examination (Gymiprüfung), offering both Langzeitgymi (LZG) and Kurzzeitgymi (KZG) tracks alongside adjacent academic support services. Its curriculum covers German (including essay writing/Aufsatztraining, grammar, text comprehension, and Deutsch als Zweitsprache) and Mathematics (including word problems, geometry, and Kopfrechnen), augmented by foreign-language instruction (English, French, Latin), simulation exams drawn from 15+ years of past papers, and specialized learning-support therapy (Dyslexie, Dyskalkulie).

The firm operates a dual-channel delivery model: live online instruction via Zoom as the primary channel, supplemented by in-person group and individual sessions at the Erlenbach classroom. Service packaging spans pay-as-you-go Einzelcoaching at CHF 140 per 60-minute session, fixed-fee group semester courses at CHF 2,800 for 22 weeks (max 6 students per cohort), multi-break Ferienkurse (holiday intensives), and a newer monthly subscription for Probezeitbegleitung (probation-period coaching). All bookings flow through a website-driven Squarespace scheduling tool with a free-consultation entry point. The company is founder-led by Franziska Basler (Inhaberin & Geschäftsführerin), operates with approximately 8 employees, and has no disclosed external institutional funding, partnerships, M&A, or patent activity. Customer acquisition is overwhelmingly referral-driven, supported by an extensive base of 5-star Google reviews from families across affluent Zürich-lakeside communities including Küsnacht, Erlenbach, Bonstetten, Zollikon, and Meilen.
