I Asked 10 AI Chatbots Where to Build SaaS. Their Answers Reveal What They Don't Know About Construction.

Last week I ran a small experiment.

I asked 10 of the biggest AI chatbots the same question: "What's an underserved B2B vertical I could build SaaS for?"

Claude. ChatGPT. Perplexity. Gemini. DeepSeek. Copilot. Mistral. Grok. Qwen. Pi.

Nine of them named construction.

Four ranked it the most underserved B2B vertical of any industry. Three more put it in the top two or three. One buried it at number six. Only one went somewhere else entirely.

I wasn't surprised by the agreement. I run ConTechFinder, a directory of 570+ construction software tools, and I've spent the last six months watching indie builders, AI tools, and market observers slowly catch on to what the data has been saying for years. The construction industry runs on software that most builders outside of it have never thought about.

What surprised me was the specificity. The AIs didn't just say "construction." They pointed at the exact sub-segments the directory data shows are underserved: specialty trade contractors, mid-market commercial GCs, small residential remodelers, firms running on spreadsheets and WhatsApp.

Two of them named Procore by name as the incumbent leaving the mid-market gap. One cited the $15 billion construction software market with 10% CAGR. Another called out the 5 to 50 technician firm size as the wedge.

Those are real, specific claims. They match what the 570 tools in the directory tell me.

But dig past the consensus and the AIs disagree on the details in ways that reveal what they do and don't know.

What the AIs got right

The AIs landed on the same broad thesis: construction is a giant, fragmented, under-digitized B2B industry where enterprise tools target the top and nothing serious exists at the bottom.

That thesis is correct. The directory data backs it up.

Of the 570 tools I've cataloged:

55% of vendors won't show a price without a sales call
Only 45% have a mobile app
9% target solo operators
Three categories have zero options for one-person operations

The math is brutal. A construction firm with five employees is the modal customer in this industry. There are 1.5 million construction firms in the US, and most have fewer than ten employees. Yet more than half the software available to them is priced through sales conversations aimed at buyers with procurement teams.

Every major AI I tested identified this gap. Grok and Qwen went further and named Procore specifically as the reason the mid-market sits empty. Grok said Procore runs "$50K+/year" contracts that are "overkill and too expensive" for the $5M to $50M contractor. Qwen called out the "90% of contractors using spreadsheets and WhatsApp" at the 5 to 50 technician firm size.

Those are accurate observations. I've watched them play out in every cold email reply and organic submission to ConTechFinder.

What the AIs got wrong

Where the AIs start to diverge from the data is in their prescriptions.

Most of them pointed at specialty trades as the answer. HVAC, electrical, plumbing, roofing, fire sprinkler, elevator, medical gas. DeepSeek gave the most specific vertical breakdown, naming fire sprinkler contractors and elevator technicians as specific niches.

Specialty trades are a real opportunity. But the directory data shows the opportunity isn't just about building a trade-specific version of Procore. It's about the form factor.

Look at which construction software tools have mobile apps versus which don't. Less than half do. Construction workers aren't in offices. They're on job sites with their phones. A tool that forces them to sit at a desk to log hours, snap photos, or sign off on safety checks isn't a tool built for their workflow. It's a tool built for the project manager watching their work.

The AI answers largely missed this. They talked about "mobile-first" in passing but never grounded it in the actual percentage of existing tools that fail the test. That's the difference between speculation and data. The AIs could only speculate.

Same story with pricing. Every AI knew construction software is expensive. None of them put a specific number on how badly vendors gatekeep their pricing. It's 55%. More than half of tools in the directory require a conversation before you can even see what they cost. An indie builder shipping a transparent $29 or $49 or $99 per month tool wins on the price-visibility axis alone, before they build a single feature the incumbent doesn't have.

The third miss: company size targeting. Only 9% of the tools I've cataloged explicitly target solo operators. Zero tools exist in three whole categories for one-person operations. That's not a mobile problem or a pricing problem. That's a "the product does not exist at any price" problem.

None of the AIs put a number on the solo operator gap. A few gestured at it, but without data they couldn't say how big it was or which categories had the deepest holes.

The outlier that made the experiment honest

Pi was the only AI that didn't name construction. It suggested mental health compliance for remote teams.

That's a reasonable answer. It's also a reminder that AI consensus isn't truth. Pi is trained on a different corpus with different weighting, and its answer reflects that. The nine agreements don't make construction the answer. They make construction the pattern most AIs have absorbed from the collective commentary about underserved B2B markets.

Which is the interesting part. AIs reflect the web's conclusions. Nine out of ten AIs saying construction is underserved tells us what the web thinks. It doesn't tell us whether the web is right.

In this case, the data says the web is right. But only because I have the data.

What this means for someone actually considering building

If you're thinking about what to build next and you landed on this post because you're already considering construction, here's the honest take from someone looking at 570 tools every week:

The opportunity is real. The AIs called the big picture correctly. There are genuine gaps at the small-operator and mid-market tiers. Procore and the other enterprise vendors cannot profitably reach down to serve them.

But the winning product isn't going to be a smaller Procore. It'll be something the AIs didn't describe well because they couldn't see the data: a mobile-first, transparently-priced, single-purpose tool built for one trade or one workflow with no sales motion required to sign up.

That could be a $29 per month daily log app for solo GCs. A $49 per month OSHA checklist for 5-person crews. A residential-remodeler CRM matching how Angi and Houzz actually deliver leads. A mobile takeoff tool for only one trade, not all of them. A multi-jurisdiction permit tracker priced for the solo contractor instead of the 50-firm GC.

None of those products exist in the directory right now at those price points with those workflows. Every one of them has a real buyer. The math works.

The AIs agreed on the vertical. They couldn't tell you exactly where to aim inside it. The directory data can.

The larger point about AI consensus

A year from now, the AIs will probably catch up. More founders will build in construction. More blog posts will name the specific gaps. More case studies will show the pricing and form factor advantages working. The training data will shift. The next iteration of Claude or ChatGPT will give a sharper answer.

For now, there's a gap between what the AIs know and what the data actually says. For anyone paying attention, that gap is the opportunity.

Nine out of ten AIs see where to look. A few more data points and they'd see exactly where to build. The builders who move now will be the ones whose products become the reference point the next generation of AIs cite.

55% of Construction Software Vendors Hide Their Pricing. I Know Because I Checked All 570.

I started looking at construction software last year and the search itself was the problem.

Capterra kept showing me Salesforce. G2 kept showing me Monday.com. Both platforms treat "construction" as a filter tag stapled onto generic SaaS, and the results punish anyone looking for something a framing crew can actually open on a phone at 6am.

So I built ConTechFinder. A directory that only lists construction software. No CRMs pretending to be field tools. No accounting suites pretending to understand retainage.

The work

I spent months cataloguing 570 tools across 15 categories by hand. No scraping, no AI summaries of vendor copy. I opened every product page, checked pricing, tested whether the mobile app existed, and read enough of the feature list to tell whether the thing was built for a GC running ten jobs or a solo remodeler writing estimates from a truck.

Doing this at volume shows you patterns no vendor wants you to see.

What the data shows

Five numbers stuck with me.

55% hide their pricing. More than half of construction software vendors refuse to publish a price. You fill out a form, a salesperson calls, you get a custom quote based on how big your company looks on LinkedIn. The industry has decided construction buyers should negotiate for software the way they negotiate for steel.

45% have a mobile app. Construction happens outside. The other 55% expect a superintendent to carry a laptop onto a muddy site, or to wait until 7pm to log the day's work from a home office. The gap between "we serve construction" and "we understand construction" sits right here.

9% target solo operators. Nine percent. Out of 570 tools, roughly 50 are built for the one-person shop. The rest assume you have an office, an admin, and at least five crew members. Independent contractors make up a huge share of US construction employment, and almost nobody is building for them.

Three categories have zero solo options. Preconstruction, BIM, and Takeoff. If you are a solo estimator bidding small commercial work, the market offers you nothing designed for your size. You either pay enterprise pricing or you use Excel.

Project Management has 45 tools. Accounting and Bidding tie for smallest at 34 each. The category everyone crowds into is the one where differentiation is hardest. The categories vendors avoid are the ones where contractors lose the most money.

What this means

For buyers: stop starting your search on Capterra. The tool built for your trade and your company size probably exists, and it probably does not rank on page one of a general SaaS directory because its founder is two people in Denver with no marketing budget.

For vendors: if you are building for solo operators in Preconstruction, BIM, or Takeoff, you have an empty category waiting. Publish your pricing. Ship a mobile app. You will stand out by doing the obvious thing.

I put the full breakdown, including every category count and the methodology, at contechfinder.com/blog/construction-software-market-data-2026. The directory itself lives at contechfinder.com.

If you sell construction software and you are not on it, the listing is free.
