Two construction-technology roundups covering the week to 9 November — Bricks & Bytes, whose byline is dated 10 November, and ConTech Roundup, dated 9 November — both listed a company called Salamandra among the week’s stealth exits. Bricks & Bytes places it in Tel Aviv, which matches the address on the company’s own site; it trades online as Salamandra AI, at salamandrai.com, and should not be confused with other Israeli firms of that name. Neither reported a funding amount, a round or an investor, and this publication could not find one either. What is public, and unusually specific for a company at this stage, is the product.
The product is Caddie Fire Safety, which the company describes in one line as “drafting software built for life safety consultants.” It runs in a browser. You upload an architectural plan in DWG format; the software “detects the floors on the sheet”; then, as the site puts it, “the AI identifies the core, measures doors and stairs, places the fire safety symbols using one consistent legend, and builds the legend and occupant load tables for every floor.” You review and correct, and export “an open DWG organized in layers,” with the architectural plan and the fire safety layer kept separate so they are, in the company’s words, “easy to work with” in AutoCAD afterwards. The code it works to is named: “Caddie Fire Safety is built in line with NFPA 101, the Life Safety Code.”
Two things about this are worth more than the launch itself.
It Drafts the Sheet. The Adjacent Tools Check It.
Analysis. The AI drawing market this publication has been tracking all year is overwhelmingly a review market. The tools read a set somebody else drew and tell you what is wrong with it. Archiboost raised $6.2m for exactly that, and appears alongside Salamandra in both of the roundups cited above. We have reported how a real contractor actually uses drawing-diff AI, and the category’s reviewers have started absorbing each other. Even where products push past review, they tend to push into the next document rather than into authorship: Bobyard went from the takeoff into the submittal.
Fire and life safety has its own review tools, and they are explicit that review is what they do. Nomic’s NFPA 101A page says its “agents flag likely NFPA 101A issues on your drawings and cite the section behind each one,” and states that a licensed professional still owns the interpretation. InspectMind’s fire and life safety checker reviews sprinkler and egress sets against NFPA 13, NFPA 20, FM Global data sheets, the IBC and the IFC, and says the engineer of record and the authority having jurisdiction “still make the final call.” Both are checkers. Caddie produces the sheet.
That is a harder problem in one specific way and an easier one in another. Harder, because an error of omission in a review is a missed finding while an error of commission in a draft is a wrong line on a sheet that goes to a plan reviewer. Easier, because the deliverable is narrow and conventional. The elements Salamandra’s own pages list it as producing — fire-rated separations, measured door and stair widths, exit signs, extinguishers and hydrants, travel distances, occupant load tables and a single legend — are a short and largely prescribed set, and the calculation behind the occupant load is set by the code rather than invented per project. Narrowing to one code and one deliverable is the trade that makes authorship tractable, and it runs against the general-purpose direction most of this market has taken.
The Pricing Is Inverted
The second thing is the business model, and the company states it plainly in its own FAQ. Asked whether there is a subscription fee, the answer is: “No. All the drafting tools, including manual drafting, are free.” The AI, it says, “is optional” — “you get a free daily allowance of AI credits, and you pay only if you choose to use more.”
Analysis. That is the reverse of the standard construction-software shape, where the seat is the subscription and AI arrives as an included feature or a tier upgrade. Here the CAD is the free tier and the inference is the meter. It is a defensible structure for a tool with this shape: a life safety consultant’s marginal cost of using the software is zero until the moment the software does the work that would otherwise have taken hours, and the thing being charged for is the thing that costs the vendor money per use. It also means the company is not asking a small professional office to commit a seat budget to find out whether the output is usable.
It is worth being clear what this publication cannot say about it. There is no published price per credit, no stated size for the daily allowance, and no disclosure of what happens to the free tier once the company has to raise again. The pricing is a statement of current posture, not a commitment.
The Service Line, and the Signature
Alongside the self-serve tool there is a second, more conventional business. A page addressed to fire safety engineers offers a drafting service rather than software: the office sends a DWG, the AI drafts, and a certified fire safety engineer completes a QA pass before the file comes back, with an editable layered DWG as the deliverable. The headline promise is “Life safety plans, drafted for you in 48 hours”; the page’s own FAQ gives the range as “within 24 to 48 hours.” The page says corrections after AHJ or plan-review comments are free, that the first project is free with no commitment, and that architectural changes after the final deliverable are billed separately. It says Salamandra “works as your office’s drafting and automation arm,” describes the founding team as fire safety engineers and technology leaders, and cites “More than 25 years designing and building thousands of projects”; it names no individuals, and no customers.
The sentence that matters most on that page is about liability rather than capability. Salamandra, it says, does not sign plans: “You stay the engineer of record: you keep full professional control and sign the plans for the client and the AHJ.” The same posture runs through the self-serve product, whose own pages say “Caddie Fire Safety suggests; you decide” and “Every line, measurement and element goes through you before it goes out.”
Analysis. That is the correct and, frankly, the only available position for a company drafting code-governed sheets with a model in the loop, and it is worth noticing how closely it tracks what the review tools in the same space say. Nomic says it does not replace the plan reviewer. InspectMind says the engineer of record and the AHJ decide. Salamandra, which goes further than either by producing the sheet, draws the same line at the signature. None of the three is selling unsupervised code compliance, and that consistency across a checker, a checker and an author is worth noting on its own.
What Is Not Established
This is a product report built on a company’s own published material and two trade roundups. There is no funding figure, no investor, no founder named, no customer named, no dated launch announcement from the company itself, and no independent assessment of output quality against a set a human consultant drew. Nor is there any evidence this publication could find about acceptance by any authority having jurisdiction — and for a tool whose output goes to a plan reviewer, AHJ acceptance is the test that matters. The company has published a clear and narrow scope, a named code and an explicit statement of where the professional responsibility stays. None of that is a result.
