SIBS has developed a market-leading technical system and production concept to streamline and ensure the quality of construction projects

With a construction system that integrates automated planning with industrial production at factory level, SIBS seeks to drive forward the development of tomorrow’s construction sector so that construction projects cost less, take less time to complete, and are more reliable.

Neptunia’s view of SIBS

Neptunia has been invested in SIBS since 2019. With its market-leading and automated design and industrial construction systems, SIBS transforms blueprints into finished buildings with exacting precision. Through technological innovation, SIBS optimises costs, delivery times and build quality.

The company has increased turnover by an average of 142 per cent in the past two years and took steps towards international expansion in 2022. At the beginning of 2023, it signed its first major agreement in the UK in its Licensing and Partnership business segment. Neptunia has been the lead subscriber to SIBS’ directed share issues in 2021 and 2022. We look forward to continuing to be an active owner that supports the company to scale its international business and develop the Licensing and Partnership segment.
