The Company

In year 2010 a mathematician with a background in software development and an engineer with background in physics joined forces to form SysMo. The venture has been a success, and we keep on working with our happy long-term clients on complex engineering and software projects. In the meantime we have become experts in many new areas and have prepared to face even more challenging problems. We are strong proponents of open source development, have always tried to use and popularize it, and have contributed back to the community with a number of open source tools.

What our clients say

Klaus Szoucsek
BMW AG, Germany
Hydrogen Storage Development

SysMo have helped us analyze the complex behavior of our hydrogen storage system, allowing us to optimize it to meet the demands of our customers. I would like to highlight the quick and focused work of Mr. Pavlov and his team. Using the models developed by them, we are able to simulate the behavior of the hydrogen storage system under all operating conditions. I will be glad to work with SysMo again in the future.

Cedric Roman
NumenGo, France

In my work, I have to deal with complex computational models. The software developed by the SysMo team has allowed me to structure my work, and not have to do repetitive tasks by hand. Now I can develop quicker simulation models, and they come automatically with interfaces to certain major simulation platforms and languages: FMI, Modelica, AMESim, Simulink.

Quality Policy

SysMo Ltd. is wholly committed to its quality policy which is in place to ensure our services fully meet the requirements of our customers at all times. We believe in the concept of customer and supplier working together in pursuing this policy and in continually striving for improvements in service quality.

Our Quality Policy is based on 2 fundamental principles:

  • Ensuring that we fully identify and conform to the needs of our customers.
  • Looking at our service provision processes, identifying the potential for errors and taking the necessary actions to eliminate them.

Within this policy we are committed to operating our Company under the disciplines and control of a Quality Management System conforming to the International Standard IS0 9001:2015.

To ensure that the policy is successfully implemented, staff are responsible for identifying customer requirements, and ensuring that the correct procedures are followed to meet those requirements.

Information Security Policy

Our information security management is based on the prevention of potential adverse events through systematic analysis of the environment, requirements of all stakeholders, risk assessment and the implementation of a set of technical and organizational risk mitigation measures.

This information security policy sets the framework for a system of measures aimed at:

  • Ensuring confidentiality of information (corporate and client) through the implementation of approved restrictions on access and disclosure of information;
  • Ensuring the integrity of information by protecting against unauthorized modification or destruction of information;
  • Ensuring accessibility of information to authorized employees by ensuring reliable and timely access to information;
  • Ensuring continuity of business processes;
  • Minimizing the security risks of information causing loss or damage to the Organization, its customers, partners and other stakeholders;
  • Minimize the degree of loss or damage caused by breakthroughs in information security;
  • Inform employees about their responsibilities and obligations regarding information security;
  • Ensuring compliance with regulatory and contractual requirements.
