Vespa Capital invested in Eserv in December 2022, attracted by its differentiated high-quality service grounded in the team's technical engineering backgrounds. This is demonstrated by minimal customer churn and high reoccurring revenue streams.

  • AS-TEG is a proven technology solution that has demonstrated efficiency benefits and cost savings across several industrial asset types, particularly the savings of onsite survey and inspection costs as well as the associated reduction in carbon footprint. 

  • Eserv’s 3D digital twins are precisely developed from assets in the field and are developed to an engineering standard of accuracy; this enables robust and reliable 3D analysis to be performed remotely. AS-TEG also consolidates an asset’s various data feeds and sources into an independent platform. This gives a single source of truth, while enabling customers to retain control and visibility of asset data.

  • Eserv’s AS-TEG technology has been used for several diverse industrial asset types particularly in the oil, gas, and nuclear sectors; the technology has the flexibility to be applied across multiple complex industrial assets providing it with ample additional opportunities for growth in adjacent sectors.
