Sierra Software Ltd was founded in 2010 and is headquartered in Nottingham, UK. Sierra Software GmbH was founded in 2018 and is headquartered in Austria. It is an owner-managed company that specialises in providing LoRa Module LoRaWAN Wireless Innovative solutions to further meet the needs and demands of the clients for their specific projects. The tight integration of the hardware and software development team with the internal production department allows great flexibility, thus enable it to quickly produce and test a new development as a prototype for pre-production stage.


We provide End to End solution for multiple industries we focus on the following 4D’s of Product Life Cycle, using strict agile methodology for project management:

  • DECIDE – We could help you conceptualize what you exactly wanted to build in software that matches your business needs.
  • DESIGN – Once you have decided what you actually needed for your project, we can now help you map these decisions to a software environment
  • DEVELOP – We will start building the software once you have chosen your design
  • DEMONSTRATE – This is the final phase of the product lifecycle which aims to prove that the software delivers your business requirements.
