What Celanio does

Celanio GmbH is a privately held German software company founded in 2006 and headquartered in Ludwigsfelde (registered in Mannheim, HRB 111337), specializing in modular seminar management software for educational institutions, corporate training departments, freelance trainers, and professional associations. The platform covers the full seminar lifecycle including course and participant management, scheduling, resource and venue planning, hotel contingent management, invoicing, and CRM lead handling, delivered through a proprietary PHP-based multi-tenant system with a custom Celanio Markup Language (CML) for document templating and a REST API that underpins an integration ecosystem spanning WordPress, Bit Form, Thunderbird, Moodle, CleverReach, easybill, and Google/Outlook calendars. The company employs approximately 9-10 people led by founder/CEO/lead developer Dennis Rogowski, with a co-founder (Kai) in an advisory role, and is entirely self-funded with no disclosed external investment.

Celanio monetizes exclusively through recurring SaaS subscriptions and ancillary services sold in the German market, with prices starting at €169/month for the Standard edition (1,500-8,000 annual participant bookings) and €399/month for the Enterprise edition (3,000-100,000,000 bookings, REST API included), plus a CRM Leadmanagement module at €20/month plus per-user fees, cloud hosting from €46/month, an E-Invoicing module (ZUGFeRD/XRechnung) at €18/month, REST API access for Standard customers from €12/month, and professional services billed at €128/hour in 15-minute units. The go-to-market is sales-led with a free initial consultation, direct sales support (Masterclass blended-learning onboarding), and a content-marketing presence via blog and newsletter; data is hosted exclusively on German servers in compliance with DSGVO, and the company reports 99.99% actual uptime over the last 10 years versus 99% contractual, with 2-4 product updates released per month. The product portfolio expanded notably in 2023-2025 with the Moodle LMS integration, REST API data-retrieval extension, Migration Assistant for onboarding from legacy systems, a WordPress Plugin, and a Thunderbird CRM plugin v3.3.
