Our Story: From Home Experiment to Energy Revolution

In 2012, Petr Vaněk, then Head of Research and Development at T-Mobile CE, decided to digitalize the technology in his house, creating a smart-home system prototype before such solutions became standard. His successful prototype inspired him to extend this technology to the industrial sector, where he established partnerships with early customers, including the visionary company Baumruk & Baumruk. Soon after, Tomáš Macák joined forces with Petr, forming a strong team that began expanding the platform into other areas, including Real Estate and Smart Cities. In 2018, Tomáš Rendla joined the team, taking FLOWBOX to a global level. We're proud that our solutions are used by global companies such as Assa Abloy and AGC, and that our innovative approach has earned us a place in the Gartner Market Guide for EMOS. None of this would have been possible without the amazing team of people behind FLOWBOX.

Our Vision

Our goal is to become a leader in modern energy management for buildings and operations through our globally competitive FLOWBOX EMOS solution. We show companies that the path to sustainability comes through increasing energy and operational efficiency, and we help them succeed on this journey.

Our Mission

We believe that we can help industry, buildings, and cities optimize their operations while using natural resources and people's time in the most sustainable way possible.

"We are convinced that the only truly clean energy is the energy that isn't produced at all."  Team FLOWBOX

What Our Team Members Say

"Thanks to FLOWBOX, we finally have all data in one place and don't have to rely on manual readings. The entire process of collection and billing has been significantly simplified and accelerated. Moreover, we can now immediately respond to any non-standard situations, which saves us time and costs. For us, this is a big step forward in digitizing energy management. Additionally, we have also deployed FLOWBOX as an IoT platform for our customer projects, where we can very quickly integrate various IoT sensors and monitor and archive measured values across Slovakia."
Viliam Malina
Project & Product Manager Towercom, a.s.
“After three years of experience, we evaluate our cooperation with FLOWBOX very positively. The technical solution meets our requirements. Thanks to the system’s flexibility and the supplier’s responsive approach, we are expanding its use to support the evolving needs of our company.”
Pavel Sedlák
Head of Energy Management at Chotěbořské strojírny, a.s.
"We chose FLOWBOX through a tender process, as it met all our requirements and also offered the most costeffective solution. At our company, FLOWBOX handles energy dispatching—from collecting data from sub-meters (electricity, natural gas, water, compressed air, temperatures), to managing 15-minute electricity peaks, power factor compensation, and evaluating specific consumption in our kilns. One of the major benefits is certainly the automatic submission of data from our local distribution network to the Grid Operator.”
Tomáš Bezděk
Energy Manager, LASSELSBERGER
"The implemented FLOWBOX EMOS system at State Opera allows us to monitor in greater detail, in real time and retrospectively, the production of heat and cooling, as well as energy and water consumption, and to analyze this data. Based on the obtained data, we can adjust the operating parameters of the relevant technologies. Additionally, the FLOWBOX EMOS system provides a comprehensive dataset necessary for energy reporting."
