OUR GUIDING PRINCIPLE
Ready for large-scale industrial projects across Europe and beyond.
Together with our subsidiary ESI and a combined workforce of approximately 180 employees, we continue to expand our service portfolio and strengthen our industrial market presence. ISI and ESI form a powerful team delivering technical excellence and first-class mechanical and electrical industrial services.
In 2022, we celebrated our 15th anniversary. Over the years, we have built an excellent reputation based on reliability, innovation and consistently high service quality.

We place great value on a respectful and trusting working environment characterized by mutual appreciation. Flat hierarchies, open communication and strong leadership accessibility create positive working conditions — ultimately benefiting both our employees and our customers.

ISI was established in 2007, building on more than 20 years of prior experience in industrial assembly and technical services.
In recent years, we have experienced significant growth — along with increasingly complex project requirements. Nevertheless, our core values remain unchanged: flexibility, quality, efficiency, adherence to deadlines and absolute reliability continue to be our highest priorities.
In February 2025, our former subsidiary Plan B Industrieservice GmbH (PBI) was merged into ISI. ISI had already been the sole shareholder of PBI since October 2021, following many years of close collaboration. This merger consolidates decades of expertise within a single organization, positioning us strongly for the future.
With approximately 180 employees, a fleet of around 120 company vehicles and 2,700 m² of office and warehouse space across two German locations, we are well equipped to serve industrial clients efficiently and reliably.
