When Bentley Systems completed its acquisition of New Zealand-based Seequent in June 2021 for $911 million — the largest acquisition in Bentley’s history at that point — the infrastructure software industry watched with a mix of interest and skepticism. The strategic rationale was clear: Seequent’s subsurface modeling portfolio (Leapfrog, GeoStudio, PLAXIS, Central) would fill the underground gap in Bentley’s above-ground infrastructure platform. The question was whether Bentley could actually execute the integration without alienating Seequent’s core mining customer base or diluting the product focus that had made Seequent dominant in its market.
Four years later, the evidence is in. The verdict is largely positive — with one significant caveat that the original sceptics were right to raise.
The financial story: better than expected
By the end of 2025, Seequent was generating approximately $365 million in annual recurring revenue— substantial growth from the revenue base at acquisition. Bentley’s CEO Nicholas Cumins noted that “even during a slowdown of mining over the past few years, Seequent continued to grow faster than the rest of the company.”
Total Bentley ARR at the end of 2025 was $1,462 million, with 2025 revenue of $1,501.8 million. Seequent’s contribution represents a meaningful share of that total and has been a consistent outperformer within the Bentley portfolio.
The financial case for the acquisition has been validated. The integration did not damage Seequent’s growth trajectory — if anything, Bentley’s distribution reach appears to have accelerated it.
The integration story: slower than promised, more coherent than feared
The original concern was that Bentley would either rush integration and break Seequent’s products, or move so slowly that the “complete infrastructure digital twin” story would remain a slide deck rather than a shipping product. What actually happened was a methodical, staged approach that preserved Seequent’s brand and operational independence while building genuine technical bridges.
Seequent retained its identity. Seequent has retained its brand and unique identity, operating as a standalone business unit focused on subsurface data modeling, analysis, and management. It now operates as “The Bentley Subsurface Company.” The Seequent brand was not absorbed or retired — a deliberate decision that reflects Bentley’s understanding of how much brand equity Seequent carried in the mining and geoscience community.
Bentley’s geotechnical products moved under Seequent, not the other way around. This was a significant and often overlooked organizational decision. All Bentley geotechnical products — PLAXIS, OpenGround, gINT, HoleBASE, and KeyLAB — joined the Seequent portfolio, creating a single center for geotechnical expertise under the Seequent umbrella rather than fragmenting geotechnical capabilities across both organizations.
Civil infrastructure integration arrived in late 2024. The introduction of OpenGround’s geotechnical extension for Bentley’s civil design applications — including OpenRoads, OpenRail, and OpenBridge — in late 2024 brought subsurface information directly into the civil design process. This is the integration that infrastructure engineers had been waiting for: the ability to access real geotechnical data inside the tools they use for road, rail, and bridge design without manual data transfer.
Tunneling workflow integration arrived in 2023. In 2023, Seequent’s Leapfrog Works and PLAXIS connected to Bentley’s OpenTunnel Designer to streamline the tunnelling infrastructure project workflow from geological modelling and geotechnical analysis to design. A real-world example: Tecne Systra-SWS Advanced Tunnelling used Bentley’s OpenTunnel Designer and Seequent’s Leapfrog Works and PLAXIS to create an all-in-one connected workflow for modelling, design, and analysis on Italy’s vast tunnel network rehabilitation program.
Seequent Evo launched in 2024. In March 2024, Seequent introduced Seequent Evo, a cloud-based platform designed to help users collaborate and manage geoscience data centrally, bringing together data from both Seequent and third-party applications into a single accessible source. This represents the platform-level thinking that the acquisition was meant to enable.
The mining concern: was it justified?
The most vocal skepticism at acquisition time came from Seequent’s mining customers, who feared that Bentley — a civil infrastructure company with near-zero mining market presence — would deprioritize mining-specific development in favor of civil integration features.
Four years later, the concern was partially justified but not catastrophically so.
Seequent’s business remains mining-dominated, and Bentley has acknowledged that mining customers represent the core of Seequent’s revenue base. Seequent software is trusted by eight of the world’s ten largest mining companies, along with thousands of major, mid-tier, and junior miners across the mining lifecycle. That customer base has not visibly defected.
However, the product development emphasis has demonstrably shifted toward civil infrastructure integration — the OpenGround extension for OpenRoads, the OpenTunnel workflow, the civil segment strategy — which is exactly what mining customers feared. Whether mining-specific feature development has kept pace with what an independent Seequent would have delivered is impossible to determine from public information. What is observable is that Bentley has not abandoned mining, but civil infrastructure has clearly become the integration priority.
Bentley’s stated view is that “regardless of what’s happening with the price of mining commodities, mining companies need to continue to understand the subsurface. They need to continue to derisk. They need to continue to be as efficient as possible.” This suggests Bentley understands the structural nature of mining demand, not just its cyclical dimension.
The legacy product question: gINT
One concrete area where original concerns materialized is the legacy gINT product. Seequent announced that support for existing gINT users will be extended to December 31, 2028, with HoleBASE transitioning to discontinued support in 2027. This is a managed sunset of legacy products — not surprising given their age and technical debt — but it does require migration effort from long-standing users. The recommended migration path is to OpenGround, which is Bentley’s cloud-based replacement.
The AI dimension: an unexpected development
One aspect of the acquisition’s value that was not widely anticipated in 2021 is how Seequent’s subsurface data capabilities have become a component of Bentley’s broader AI strategy.
Bentley has described infrastructure organizations as leveraging subsurface insights from Seequent alongside past project design data and the engineering logic embedded in Bentley Open Applications to ensure their AI models are informed by the right context.
A concrete example: a geothermal energy project in Turkey used AI and GPU-accelerated simulations through Seequent software to compress a five-year development timeline to just one year and reduce costs by 75%, with engineers evaluating over ten million scenarios in days and conducting 3,000 simulations in hours.
Subsurface data as AI training context and simulation substrate was not part of the original acquisition narrative. Four years on, it has become one of the more compelling use cases — and one that positions Bentley-Seequent ahead of competitors who lack equivalent subsurface depth.
Where Bentley-Seequent stands competitively in 2026
The acquisition has delivered on its primary competitive objective. A lack of certainty about the subsurface is a real and expensive headache for civil infrastructure projects. According to the CRUXInsight report 2024, unforeseen physical conditions were the second most common cause of claims and overruns on transportation infrastructure projects, with claims on 384 tracked transportation projects in 2024 costing an average of $324 million per project while time overran by 70%.
Bentley is now the only major infrastructure software vendor with a production-quality integrated surface and subsurface platform. Autodesk has no equivalent subsurface offering. Trimble has partial geotechnical capability but not a comprehensive subsurface modeling suite. Hexagon has strong mining capabilities through its own portfolio but weaker civil infrastructure integration.
The gap Bentley identified in 2021 was real, and they have closed it.
The honest assessment
The Seequent acquisition has been a financial success and a strategic success by most observable measures. Revenue has grown significantly. The Seequent brand has been preserved. Civil infrastructure integration has arrived, if more slowly than the most optimistic projections. Mining customers have not defected at scale.
The areas where original concerns were valid: civil integration has received more development attention than mining-specific features, legacy product users face migration effort, and the full “seamless” surface-to-subsurface workflow that was promised in the acquisition narrative is still arriving in stages rather than complete.
For AEC firms evaluating their software strategy in 2026, the practical implication is clear. If your project portfolio includes tunnels, deep foundations, dams, contaminated sites, or any infrastructure where ground conditions are a material risk — and the CRUXInsight data suggests that for transportation infrastructure they almost always are — Bentley-Seequent now offers an integrated workflow that did not exist four years ago. The case for evaluating it is stronger than it has ever been.
