  • Property software

    Waitlist

    Urbario is software for service charge statements for residential and commercial property. It brings master data, receipts and advance payments together in one place, allocates costs according to stored allocation keys and produces a finished statement.

  • SaaS infrastructure

    Early access

    A SaaS product needs user accounts, sessions, API keys, subscriptions, invoices and usage limits. These functions are almost the same in every product, and they still have to be built, tested and maintained each time. Authiane provides them as one platform that you run in your own infrastructure, so this work is done once.

    Live · Hotel area: preview

    No 6 a.m. sprint required: Handtuch Held ends the towel race at the hotel pool. Loungers are assigned fairly and calmly – steered by the hotel, relaxed for guests.

    At a glance

    • One guest, one lounger.
    • Pools, areas and rules remain firmly in the hotel's hands – the operation decides, not the early birds.
