Mission and Vision

We have serious plans with PROPSTER

With our B2B SaaS solution, we support construction companies and real estate developers  in the execution of many real estate projects. The focus lies on the optimisation of processes, the communication and the organisation between the consumer and the construction company or real estate developer. Our tool can easily be integrated in the marketing of the projects and remains in use until the handover and the defect management.

Cases of use

  • Marketing & Sales
  • Individualisation
  • Online Sampling
  • Handover
  • Defect Management

01 / SaaS

These are the areas we cover with our software

We start exactly where the effort and the challenges in processing begin; with the buyer. Most current processes focus on technical handling and communication between the real estate developer and the executing company. The consumer is usually left out.

We close this gap and offer our clients customers an optimal overview of all topics that are relevant for the individualisation process. That is the basis for an equally frictionless process for the project managers, who administrate the requests.

This creates a frictionless process between managers and administrates the requests.

02 / Investors are welcome

We are preparing the next round of funding for 2021

We are preparing the next round of funding for 2021

After an eight-month test phase and a successful proof of concept and proof of market in mid-2017, Milan Zahradnik founded the Sonderwunsch Meister GmbH with three Business Angels in Vienna in September 2017.

After this successful seed round, we plan the first funding round to further promote the internationalization in the course of 2021.

03 / Marketplace and Reseller

We keep an eye on the entire value chain

Our marketplace brings together relevant manufacturers, real estate developers, general contractors and construction companies.

In addition, we would also like to expand our reseller program and inspire companies for whom PROPSTER represents a sensible expansion of their portfolio.
