AMMON

What AMMON does

AMMON (legal name: Maik O. AMMON) is a Schwelm, Germany-based software company founded in 1992 that has developed the *A*MMON Immobilienmakler-Software, a CRM and property-management platform purpose-built for the German real estate industry. The product is built on a Delphi desktop application with a SQL database engine, supporting all current Microsoft Windows and Office versions, with optional terminal-server/cloud deployment and dedicated iOS and Android applications for on-the-go access. Native integrations span all major German property portals (ImmobilienScout24 via REST-API, Immowelt, Immonet, Immopool, openImmo 1.2.7, IVD) plus adjacent systems (Outlook, Google, iCloud, openAI, Ogulo, Giraffe 360, ebay Kleinanzeigen, Kalaydo), and the platform encodes German regulatory logic \u2014 DSGVO/BDSG consent management, Maklervertrag written-form compliance, XRechnung e-invoicing, and ImmoWertV/NHK 2010 valuation standards \u2014 directly into workflow automation such as the portal-inquiry autoresponder and digital selection matching.

The company operates an all-inclusive concurrent-user licensing model: customers pay an annual fee per simultaneous connection (not per named user), receive every feature module without add-on purchase, and get free updates and unlimited support without a maintenance contract. The pricing model has no usage tiers, making monetization predictable per seat but tightly linked to customer headcount rather than transactions or volume. Distribution is direct \u2014 a personal sales team handles inbound demos (on-site or remote) and a free 30-day trial can be self-downloaded from the website \u2014 with no resellers, channel partners, or institutional capital backing. The company also generates ancillary training revenue (\u20ac249 per participant for external seminars, \u20ac499 in-house daily rate) and has begun monetizing an AI flatrate subscription for unlimited OpenAI-driven text generation. AMMON serves over 3,000 licensees across German real estate brokers, project developers and Bautr\u00e4ger, property managers, housing cooperatives (Wohnungsgenossenschaften), financial service providers, and Zwangsverwalter.

The business is a founder-owned sole proprietorship with 11\u201350 employees and a continuous public release history extending through mid-2025. No acquisitions, subsidiaries, or institutional funding rounds have been disclosed; growth has been funded organically over 33 years. Recent strategic emphasis has shifted toward layered AI features (OpenAI text generation, AI flatrate), mobile platform extension (the AMMON \u00dcbergabe App launched 2024 for property-handover protocols), and pre-emptive regulatory positioning around the 2025 B2B e-invoicing mandate. Revenue is not publicly disclosed and there is no LinkedIn, careers page, or investor disclosure surface visible.
