Bentley Just Posted 14% Growth With 82% Gross Margins. So Why Was It Missing From Construction’s Biggest Pre-Con Event?
Bentley Systems just posted Q1 2026 revenue of $424M, up 14.5% year over year, with a trailing gross margin around 82% and free cash flow of $188M. By any reasonable measure of a public software company, that is a strong quarter. The infrastructure engineering business is humming. But at Advancing Preconstruction 2026, the largest preconstruction event in North America, the sponsor list was Zebel, Procore, Autodesk, ConstructConnect. Bentley wasn’t there. Two weeks later, Bentley announced a $3M startup accelerator focused on AEC software. The two things together aren’t a coincidence. They look like a company that recognized, late, that the action in vertical construction software has moved somewhere they don’t sit.
It is easy to be misled by Bentley Systems’ financial profile right now. Q1 2026 numbers look excellent. Revenue of $424.2M, up 14.5%. ARR of $1.49B, up 13.3%. Free cash flow of $187.9M for the quarter and $492M trailing twelve months. Net revenue retention of 109%. Operating margin near 30%. Trailing gross margin sits around 81.6% to 81.9%, which is elite even by software standards.
This is what a category-leading public software company looks like in a year when most peers are getting punished for slower growth. So the obvious next question is: why was Bentley nowhere to be seen at the most important preconstruction conference of the year?
Advancing Preconstruction 2026 ran in Glendale, Arizona from May 5-7, with more than 1,000 senior preconstruction and estimating decision-makers attending. The sponsor list reads as a who’s who of vertical construction software: Zebel as Lead Partner, ConstructConnect and Procore as Expertise Partners, Autodesk Construction Cloud as a Program Partner. Bentley does not appear anywhere on the list. Then on May 14, exactly one week after the conference ended, Bentley announced NXT Activate, a $3M accelerator backing early-stage AEC software startups. The first cohort begins autumn 2026.
You don’t write the venture check unless you’ve already concluded the building won’t happen fast enough inside the house.
The two markets nobody talks about as separate
Bentley dominates infrastructure. Pre-con happens in vertical.
Construction software gets discussed as if it’s one market. It is not. There is infrastructure engineering software, where the buyer is a department of transportation, a rail operator, a water utility, a mining company, or the consulting engineers serving them. Then there is vertical construction software, where the buyer is a general contractor, a developer, an owner, or an estimator working on a building project. Bentley is the clear leader in the first category. CEO Greg Bentley described the Q1 results as “underscoring the resilience of our business model and the growing demand for infrastructure software solutions globally.” Note the word infrastructure.
The Advancing Preconstruction conference is a vertical event. It serves general contractors doing estimating, bidding, design coordination, and value engineering on commercial and institutional buildings. Owners and trades from the same world. None of that is Bentley’s home turf. So one defensible read of the absence is: of course they weren’t there, it isn’t their market.
The harder question is whether that defense holds up for much longer. The vertical pre-con software market is exactly where venture capital is concentrating right now. Zebel, the lead sponsor of Advancing Preconstruction 2026, sells AI estimating to commercial GCs. Procore is sitting on a multi-billion dollar revenue base built almost entirely on the vertical side. Autodesk spent $275M to acquire BuildingConnected for that market. The center of gravity of construction software dollars and attention has shifted vertical, and Bentley has not followed.
What infrastructure focus actually buys you
High margins, slower competition, and the IIJA tailwind
Now the steelman. Staying out of vertical pre-con isn’t obviously a mistake. Infrastructure is a very specific market with very specific advantages.
The customer base is more concentrated. Departments of transportation, utilities, rail operators, and large engineering consultancies have longer sales cycles but bigger seat counts and stickier contracts. Net revenue retention of 109% is what you get when your customers can’t easily switch off MicroStation, ProjectWise, or SYNCHRO without ripping out years of project data. The trade-off is slower growth than vertical, but the margin profile is better and the competitive intensity is lower. Bentley’s 82% gross margin reflects an environment where there are simply fewer companies fighting for the same dollar.
There is also a multi-year tailwind. The US Infrastructure Investment and Jobs Act is still pushing money into roads, bridges, water, and rail. The new German €500B infrastructure fund is starting to deploy. UK infrastructure is moving through the Building Safety Act and into delivery. These are all Bentley’s markets, not the GC vertical’s. The macro is unusually friendly.
So a CFO can defend the strategy with a straight face: stay focused on the segment where you win, harvest the margin, return capital, and let Autodesk and Procore knife each other in the vertical knife fight. That is a coherent position.

Why the absence still reads as a warning
Vertical pre-con is where the platform plays are forming
The problem with the defensive reading is that vertical construction software isn’t sitting still. Pre-construction is the active battleground in construction technology right now. Estimating is being rewritten by AI. Takeoff is being commoditized. Cost intelligence platforms are emerging. New entrants like Ediphi, Togal, Stack, and Toggle are building infrastructure-grade software for vertical contractors that previously had nothing better than spreadsheets and disconnected point tools.
The market is also bigger than it looks. Aconex was sold to Oracle for $1.6B in 2018. PlanGrid sold to Autodesk for $875M in the same year. BuildingConnected went for $275M. Procore IPO’d at a $9.6B valuation. These outcomes did not come from the infrastructure side. They came from selling software into GCs, owners, and trades on the vertical side of the industry. That is the side where the AI rewrite is now happening fastest, and it is the side Bentley is least positioned for.
The deeper concern, voiced by Dustin DeVan and Patric Hellermann on the latest Bricks, Bucks & Bytes, is that the moats Bentley is harvesting in infrastructure today don’t necessarily extend forward. As AI-native tools eat into design seats, project data layers commoditize, and open-source standards like IFC and 3D Tiles spread, the integrations and data lock-in that protect ProjectWise and MicroStation start to look more vulnerable. Greg Bentley has been remarkably candid about this on earnings calls, talking openly about open-source-adjacent strategy and the company’s new CTO Julien Moutte. The leadership knows.

You don’t fund external startups for a problem you’re solving in-house
Which brings us back to the May 14 announcement. NXT Activate puts $3M over three years into AEC software startups, in a model that explicitly does not lock startups into Bentley’s stack. The press release is unusually direct: “the programme is uniquely designed to support startups, regardless of the technology they choose to build on. Whether a company is building on open standards, such as IFC or 3D Tiles, or leveraging proprietary platforms, they are eligible for funding.”
That sentence is not what you say when you’re confident your own roadmap will get you to where the market is heading. It is what you say when you’ve concluded that the next generation of AEC tooling will come from somewhere outside the company’s walls, and that the best you can do is put yourself in a position to partner with, integrate with, or eventually acquire the winners. The accelerator is not a marketing exercise. It’s a hedge against the limits of organic R&D.
This is also the read that explains why Bentley wasn’t at Advancing Preconstruction. The company is responding to the vertical software shift, but it’s responding through corporate venture and accelerator-style bets rather than through direct product competition in pre-con. That is a defensible choice. It is also a choice that has costs. Customers attending the biggest pre-con event of the year saw Procore, Autodesk, and Zebel demoing live. They did not see Bentley. Whatever lands out of NXT Activate in 2027 or 2028 will arrive too late to influence the buying decisions being made now.

Bentley does not appear on the official 2026 Partners page for Advancing Preconstruction. The published partner tiers (Lead, Expertise, Program, Hosting, Innovation, Exhibition, Event) include Zebel, ConstructConnect, Procore, and Autodesk among others, but not Bentley Systems. The conference ran in Glendale, Arizona from May 5-7, 2026 with over 1,000 attendees. (Source)
Bentley operates as an infrastructure engineering software company with a subscription-heavy model and a customer base that doesn’t easily switch off the platform. Subscriptions made up 93% of Q1 2026 revenue. The combination of high customer lock-in, low cost of goods sold, and pricing power gives Bentley a TTM gross margin around 81.6% to 81.9%, which is elite even by software standards. Bank of America projects a sustained gross profit margin of 82%. (Source)
NXT Activate is a $3M accelerator launched on May 14, 2026 by Bentley and NXT BLD (organized by AEC Magazine). It will back six to eight AEC software startups per cohort over three years, starting autumn 2026. The accelerator is intentionally vendor-agnostic, supporting startups building on open standards like IFC and 3D Tiles as well as proprietary platforms. The timing, one week after Advancing Preconstruction ended, signals that Bentley is responding to vertical AEC innovation through corporate venture rather than direct product competition. (Source)
Not entirely. Bentley does sell into vertical markets in some cases (large mixed-use developments, industrial facilities), and Autodesk does sell into infrastructure (Civil 3D, InfraWorks). But the bulk of revenue, the dominant customer base, and the strategic focus of each company sit clearly on one side or the other. For preconstruction specifically, which is overwhelmingly a vertical-construction workflow concept, the split is sharp enough to explain why one set of vendors shows up at Advancing Preconstruction and the other doesn’t.
It could, and that’s arguably what NXT Activate is preparing for. Accelerators serve as long-dated deal pipelines for corporate venture arms. The risk is timing. Autodesk acquired BuildingConnected in 2018. Oracle acquired Aconex the same year. The window for cheap, strategically obvious pre-con M&A may already be closing as standalone leaders raise larger rounds and price their valuations against an AI-native software thesis. Bentley arriving in 2027 or 2028 may be paying a premium to acquire what could have been built or bought earlier. (Source)
Two things. First, the corporate venture money in AEC is starting to position around the vertical pre-con shift, which means strategic acquirer interest is rising for the strongest startups in that segment. Second, infrastructure software remains a quieter but very high-margin market that gets less venture attention than it probably should. Founders building for departments of transportation, utilities, and large engineers may be operating in a less crowded category than the takeoff-tool flood that dominates current YC cohorts.
