ARV

What ARV does

GRÜN ARV GmbH (formerly Allgemeines Rechenzentrum für Verbände und Vereine GmbH, founded 1975 in Hamburg) is a German software-and-services vendor specializing in member and policyholder administration for non-profit associations, federations, and insurance-administration entities. Following its December 19, 2025 acquisition by GRÜN Software Group GmbH, the company operates as part of the group's 'Plattform Institutionen' cluster, serving German-speaking Vereine (clubs), Verbände (federations), and Versicherungen (insurance administrations) with named clients including Sozialverband VdK, Volkssolidarität, SoVD, ERGO Lebensversicherung, and a long tail of sports clubs such as Turngemeinde Bornheim and Niendorfer TSV. The aggregated customer base administers more than 1.2 million members.

The product portfolio centers on three browser-based SaaS applications hosted in GRÜN ARV's own data centers in Hamburg: GRÜN CHAMP.MV (member management, contribution billing, facility planning, and access control for sports clubs), GRÜN VIVA.Web (multi-level federation management with delegations, dunning, and DATEV integration), and GRÜN VITA.Web (insurance policyholder and contribution management). CHAMP.MV is extended by the CHAMP.KTH course-management module, Mitglieder Online (digital membership applications), and Mitglieder Login (self-service portal). The stack integrates with DATEV accounting, online-banking, E-Post Brief digital mail, NFC/RFID access systems, and German sport-bund (HSB/DOSB/LSB) annual reporting.

GRÜN ARV earns revenue through a layered model combining subscription software licensing, Managed SaaS (mSaaS) bundles that include business process outsourcing (member management, contribution collection, digital dispatch, access control), SaaS-as-IT-Outsourcing infrastructure hosting in its own data centers, and project-based implementation plus ongoing support services. Pricing is quote-based, annualized, and depends on member structure and required processes. The company sells exclusively through a direct, consultative field-sales motion targeting German enterprises, supported by website contact forms, phone sales, and customer testimonials — with no channel partners and no geographic expansion beyond Germany.

Core offering

GRÜN ARV develops and operates browser-based SaaS software for member and association administration, anchored by three core products: GRÜN CHAMP.MV for sports clubs, GRÜN VIVA.Web for associations and federations, and GRÜN VITA.Web for insurance administration. The portfolio is delivered as hosted SaaS in the company's own German data centers in Hamburg, and can be combined with a Managed SaaS (mSaaS) layer that adds outsourced business process services such as contribution collection, dunning, digital postal dispatch, member IDs and NFC/RFID access systems.

Product overview

GRÜN ARV offers a modular software-as-a-service portfolio built around three core products — GRÜN CHAMP.MV for sports clubs, GRÜN VIVA.Web for associations, and GRÜN VITA.Web for insurance administrations — all browser-based and centrally hosted in GRÜN's own German data centers. CHAMP.MV can be extended with the CHAMP.KTH course management module, plus Mitglieder Online (digital membership applications) and Mitglieder Login (member self-service). The product suite is complemented by a layered services model: SaaS as IT-Outsourcing for pure infrastructure hosting, Managed SaaS (mSaaS) with Business Process Outsourcing for fully outsourced operations including membership management, contribution collection, digital postal dispatch, newsletter services, and NFC/RFID access systems, and further services covering implementation, software updates, and ongoing support.

Others

• GRÜN Software Group: Strategic parent company of GRÜN ARV since December 2025; a German vertical-software group with ~500 employees serving institutions and adjacent verticals. Comparable as the integration counterpart and a cross-sell/competition risk if GRÜN platforms overlap on institution customers.

Broad incumbents

• Blackbaud: Large US-listed vertical SaaS provider for non-profits and associations with fundraising, CRM, and member management capabilities. Broad incumbent operating at scale in the same end-market.
• Salesforce.org (Nonprofit Cloud / NPSP): Enterprise CRM and nonprofit-cloud offering that competes for member/association management workloads at German non-profits. Broad incumbent with global scale and modern cloud architecture, contrasted with ARV's on-prem-style German hosting.

• ClubOffice: German SaaS for fitness studios, sports clubs, and associations with member management, contribution billing, and access-control features. Comparable on Vereine segment and on the mSaaS-style bundled offering.
• SportMember: Cloud-based club management SaaS for sports clubs in Europe, covering member management, contribution collection, and communication. Competes directly with GRÜN CHAMP.MV in the German sports-club segment.
• Linear GmbH (Vereinssoftware): Provides Verein- and Verbandsverwaltung solutions for German-speaking organizations. Direct peer on member data management, contribution processing, and DATEV integration.

Regional players

• DFBnet / DFB-Medien: Operates the DFB's official sports administration and reporting systems used by German football clubs and associations. Comparable on the German sports-federation management workflow and Bestandsmeldung reporting that ARV also supports.
