How to Value an Engineering Software Company in 2026

Engineering software is one of the few categories where I routinely see founders underestimate their own business. A $12M ARR CAD add-on or a simulation tool embedded in an aerospace workflow isn't a "small software company" — it's a strategic asset that Autodesk, Hexagon, Siemens, PTC, or Ansys will pay a generational multiple for.

The gap between what a generalist M&A advisor will tell you your engineering software company is worth and what a well-run process will actually produce is often 2-3x. Let me walk you through how this category really trades.

Why Engineering Software Trades at a Premium

Generic horizontal SaaS trades at 4-8x ARR in today's market. Engineering software routinely trades at 8-15x ARR, and the best assets go higher. The reason isn't magic — it's structural.

Once a CAD file format, a simulation mesh, or a PLM schema is embedded in an engineering team's workflow, ripping it out is a multi-year project. Designs, drawings, and historical analyses all live in that format. Switching vendors means retraining engineers, re-validating simulations, and risking IP loss on legacy projects. That's why gross retention in engineering software regularly hits 95-98%, compared to 85-90% for horizontal SaaS.

Buyers pay for that retention. When Hexagon acquired Infor's EAM business for $2.75B in 2023, they paid roughly 6x revenue on a mature asset. When Ansys sold to Synopsys for $35B in early 2024, that was roughly 16x revenue on a business growing 12% organically. These weren't outliers — they reflect what strategics will pay to lock up workflow-critical software.

The Multiples by Size and Growth

Here's what I see across actual engineering software transactions in the $5M-$100M ARR range:

• Under $5M ARR, <30% growth: 5-8x ARR. Too small for strategics, mostly sold to PE rollups or larger engineering software companies as tuck-ins.
• $5-15M ARR, 30-50% growth: 8-12x ARR. This is where strategic interest really begins. Autodesk, PTC, and Bentley all have corporate development teams actively hunting in this range.
• $15-50M ARR, 40%+ growth: 10-15x ARR. Platform-grade assets. Expect a full auction with 4-6 serious bidders if the process is run properly.
• $50M+ ARR, Rule of 40 >60: 12-20x+ ARR. These are scarce assets and priced accordingly. See Ansys/Synopsys, Altair/Siemens ($10B, roughly 15x), or Aveva's take-private at ~13x.

Notice how tight the growth-multiple relationship is. A business growing 25% and a business growing 45% in the same ARR bracket will see a 3-4x multiple gap. That's not irrational — it's the buyer pricing the next 5 years of compounding into the deal.

What Drives Multiples Within the Range

Two engineering software companies with identical ARR and growth can sell for very different multiples. Here's what separates the 8x outcomes from the 15x outcomes.

Net revenue retention. This is the single biggest lever. A company with 120% NRR grows its installed base organically without sales spend. At 110% NRR, the business is healthy. Below 100%, you're running up a down escalator. I've seen bidders walk away entirely from companies with sub-100% NRR regardless of logo growth, because they can do the math on CAC payback and don't like the answer.

Seat expansion mechanics. Engineering software that charges per seat and sits inside growing engineering teams has a natural tailwind. If your average customer added 2 seats last year without any sales effort, that's pure ARR expansion and gets priced at the top of the range.

Industry concentration. Counterintuitively, deep concentration in a single vertical (aerospace, automotive, oil and gas, semiconductors) is a positive, not a negative — as long as you're the dominant player in that niche. Hexagon paid a premium for CAESAR II because it owned piping stress analysis in the energy sector. Being the default tool for a workflow is worth more than being "one of several" across many workflows.

Perpetual license exposure. Many legacy engineering software companies still have 20-40% of revenue coming from perpetual licenses plus maintenance. Strategics will heavily discount the perpetual portion — maintenance revenue trades at 3-5x, not 12x. If you're still on perpetual, converting to subscription in the 24 months before a sale can literally double your valuation. I've watched founders do this and add $40M+ to their exit.

Who Actually Buys Engineering Software

The buyer universe is small but deep-pocketed. The strategic acquirers I see active in almost every process:

• Autodesk — aggressive in AEC, manufacturing CAD, and construction. Paid $1B for Innovyze (water infrastructure), $240M for Spacemaker (AI site design).
• Hexagon AB — relentless acquirer in metrology, design, and simulation. 40+ acquisitions in the last decade.
• Siemens Digital Industries Software — deep pockets, long integration timelines. Bought Altair for $10B in 2024.
• PTC — CAD, PLM, and IoT. Paid $1.47B for ServiceMax, $1.06B for Arena.
• Bentley Systems — infrastructure-focused, steady stream of tuck-ins.
• Ansys/Synopsys, Cadence, Dassault Systemes — simulation and EDA consolidators.

Behind the strategics sits a well-organized PE buyer pool: Thoma Bravo, Vista Equity, Hg Capital, Battery Ventures, and Francisco Partners all run dedicated engineering software theses. For sub-$50M ARR assets, PE is often the best-priced buyer because they're rolling you into a platform and can underwrite synergies.

The Retention Math Buyers Actually Run

When a buyer's corp dev team opens the model on your company, the first thing they build isn't a DCF. It's a cohort retention analysis. They want to see every customer you've ever signed, bucketed by signup year, and how much ARR each cohort generates today.

A cohort that's generating 130% of its original ARR five years later tells the buyer this is a compounding asset. A cohort that's at 70% after five years tells them they're buying a melting ice cube. Same top-line ARR, completely different valuations.

Before you go to market, build this analysis yourself. If the numbers look bad, fix the underlying churn drivers before running a process — not during one.

What Destroys Value in Engineering Software

Founder-led sales with no repeatable motion. If every deal over $100K closes because you personally know the VP of Engineering, buyers will discount heavily. They're buying a machine, not a person. Build a sales team with quota-carrying reps closing real deals before going to market.

Concentration in one customer. One customer over 20% of ARR is a yellow flag. Over 30% and buyers will structure the deal with massive earn-outs tied to that customer's retention. I've seen $80M headline deals where $25M was tied up in a single-customer earn-out.

Technical debt that blocks cloud migration. If your software is still desktop-only and the codebase can't be containerized, strategics will either pass or price in an 18-month re-platforming cost. Get ahead of this.

Weak IP position. Engineering software lives and dies on defensibility. Patents, proprietary algorithms, and hard-to-replicate numerical methods all command premiums. If your moat is just "we've been around a while," expect a commodity multiple.

How to Maximize Your Exit

If you're 18-24 months from selling, focus on three things. First, get NRR above 115% — every point matters and compounds into the multiple. Second, convert any remaining perpetual revenue to subscription; strategics will underwrite the subscription ARR at full multiple. Third, build one or two strategic partnerships with the likely acquirers — a Hexagon reseller agreement or an Autodesk marketplace listing creates natural buyer awareness and drives competitive tension in the process.

Run a real auction. Engineering software buyers are sophisticated and will pay their best price only when they believe someone else is also paying. A banker who can bring 4-6 credible bidders to the table will typically add 20-40% to the final number versus a bilateral negotiation.

The Bottom Line

Engineering software is a scarce asset class with a deep buyer pool and structurally high retention. If you run your business well and run your process well, 10-15x ARR is a realistic outcome for a growing, sticky, vertical-focused engineering software company. Don't let a generalist tell you it's a 5x business. Understand the category, understand the buyers, and negotiate from a position of knowledge.
