Congressus

What Congressus does

Congressus B.V. is a privately-held Dutch SaaS company founded in 2010 by Jochem Pastoor and headquartered in Groningen, Netherlands. The company builds an integrated association management platform (verenigingssoftware) that consolidates member administration (CRM), content management (CMS), financial administration with Dutch payment rails (iDEAL, WERO, SEPA direct debit), and member communication (email, SMS, forum) into a single cloud product branded as Congressus Manager, with a companion mobile app and a public REST API (v30). The platform is modular, with add-on products spanning event ticketing and QR access control (Event Scan App), a digital member portal, webshop, rental management, and a form builder; key integrations include Mollie (payments), Exact Online and Moneybird (accounting sync), Google and Microsoft (SSO), and Amazon SES (email delivery).

Congressus serves Dutch membership-based organizations — student associations, study associations, professional and industry associations, auto clubs, and other verenigingen — and reports more than 400 customer associations on the platform, with publicly cited 2021 scale metrics including roughly 20 million pageviews on customer sites, 2.8 million+ emails sent, 10,000+ events organized, 220,000+ event participants, and €7.5M+ in payment volume processed; the same source discloses approximately 35% growth for that year. The team has expanded from a single founder to seven people, all hired organically without disclosed external funding.

Revenue is subscription-based via tiered Starter, Pro and Enterprise packages billed monthly, with additional recurring fees for subsites (€11.50/month ex. VAT), the rental module, and a per-ticket transaction fee for QR scanning. Go-to-market is product-led — a 30-day free trial with self-serve sign-up via KVK lookup — supplemented by inside sales for mid-market and direct sales conversations for the Enterprise tier. The company is bootstrapped (no funding rounds, acquisitions, or structural changes disclosed), is privately held as a Dutch B.V., and operates exclusively in the Netherlands.
