E1 Acquires 12Build, Forging a Global ConTech Powerhouse

NIJVERDAL, Netherlands & MELBOURNE, Australia – January 23, 2026 – In a landmark move for the global construction technology sector, Australian market leader E1 has acquired 12Build, a leading European construction tendering platform. The deal, supported by E1’s long-term private equity backer Potentia Capital, creates a formidable international player in the digital procurement space, combining E1's dominance in Australia and New Zealand with 12Build's strong foothold across Europe.

This acquisition is more than a simple expansion; it represents a significant consolidation in the rapidly evolving ConTech market. By bringing 12Build into its fold, E1 (formally known as EstimateOne) is executing a deliberate strategy to build a global platform, uniting two companies founded nearly two decades ago on the shared principle of simplifying the complex construction tendering process. While the financial terms were not disclosed, the move is set to accelerate innovation and reshape the competitive landscape for construction software.

A Strategic Play for Global Leadership

The acquisition of 12Build is a cornerstone of E1’s aggressive “Buy & Build” strategy, which aims to consolidate the fragmented construction software market and establish a dominant global presence. This is not E1's first major strategic move; the company recently acquired C-link, a UK-based post-award contract management solution, demonstrating a clear intent to control the entire procurement lifecycle from initial tender to final contract.

Backed by Potentia Capital, a Sydney-based firm specializing in high-growth technology businesses, E1 is well-capitalized to pursue this global ambition. The strategy involves identifying strong regional leaders like 12Build and integrating them into a larger ecosystem, creating synergies while allowing them to maintain their local focus. With E1’s projected Annual Recurring Revenue (ARR) expected to be roughly double that of 12Build by the end of 2025, the Australian firm is leveraging its scale to accelerate its international expansion.

This move is reflective of a broader trend in the ConTech industry, where M&A activity is on the rise. As digitization becomes standard in construction, the demand for unified, comprehensive platforms is growing. By combining forces, E1 and 12Build are positioning themselves to meet this demand, offering a more extensive network and a richer feature set than many smaller, regional competitors could provide alone.

Local Roots, Global Reach

Despite the global scale of the acquisition, both companies have been emphatic that 12Build will maintain its operational independence and distinct European identity. The entire leadership team at 12Build will remain in place, with Patrick Aarbodem continuing as CEO and founder Erik Nieuwenhuis staying on as a minority shareholder, board member in the E1 group, and strategic contributor.

This commitment to continuity was a crucial element of the deal. “For me, the cultural and strategic alignment was a decisive factor,” said Erik Nieuwenhuis, Founder of 12Build. “From the first conversations, it was clear that E1 shares our way of thinking about construction technology and how to build a company with a strong culture for the long term. That alignment gives me confidence that this step will strengthen our ability to innovate and continue building what 12Build stands for.”

The preservation of culture and local expertise is intended to reassure 12Build’s extensive customer base of general contractors and suppliers. The message is clear: the platform they rely on will not change overnight. Instead, it will be enhanced by the resources of a larger group.

Patrick Aarbodem, CEO of 12Build, echoed this sentiment. “We found more than just a partner in E1. We found a team that speaks our language, is closely aligned in culture and has the same passion for the construction industry,” he stated. “Our focus remains exactly where it should be: delivering a reliable, high-quality tendering platform, now with greater strength to invest in our product and our people.”

For E1, this model allows them to gain an immediate, established presence in the complex European market without the risks of starting from scratch. E1 co-founders Michael Ashcroft and Andrew Ritchie noted the acquisition is a “defining moment,” stating, “Joining forces with 12Build allows us to take that ambition global, combining two deeply aligned platforms while preserving what customers value most in each market.”

Fueling the Next Wave of ConTech Innovation

The primary driver behind the acquisition, beyond market share, is the acceleration of product innovation. With combined resources, the group plans significant investments in key technological areas that promise to make the tendering process smarter and more efficient.

At the forefront is a heavy focus on Product & AI Innovation. The companies aim to develop more advanced capabilities for document processing, data extraction, and intelligent matching. This could translate into features that automatically analyze tender documents, identify relevant opportunities for subcontractors, and automate routine communication, saving countless hours for estimators and project managers. The goal is to move beyond simple document exchange and create a platform that provides actionable insights.

Furthermore, the group has signaled its intent to pursue measured expansion into complementary technologies. This includes potential acquisitions or in-house development of tools for BIM (Building Information Modeling) analysis and digital take-offs, which would allow users to extract quantities and estimates directly from 3D models within the procurement platform. This deeper integration would create a more seamless pre-construction workflow, a long-sought-after goal in the industry.

These advancements will be powered by a continued investment in people and talent. The combined entity, which includes 117 FTE at E1 and 73 FTE at 12Build, will focus on attracting and retaining top engineering, product, and customer support talent to drive this ambitious roadmap forward. As the two platforms share learnings on everything from pricing models to feature adoption, the pace of innovation is expected to increase significantly for users in all regions.

As the ink dries on the deal, with Stifel having served as the financial advisor to 12Build, the newly expanded group stands as a testament to the maturation of the ConTech market. The combination of E1’s scale and 12Build’s European expertise creates a global procurement platform poised to not only compete but to define the future of digital tendering. The industry will be watching closely as this powerful new entity begins to execute its vision for a more connected and efficient construction world.
