What is shipping today

It is already built, and it is already sold.

Mirror Engineer packages a trade contractor’s entire back office into one HTML file he owns outright — his public website, his crew board, his schedule, his invoices, his price history, his estimating sheet, his yard signs. He double-clicks it. There is no server to rent, no seat to license, no subscription to cancel, and it works on a job site with no signal, on a desktop or a phone.

Why this is the important half. The estimating engine is the technology. The pack is the distribution. Every contractor who buys one is a business already running on Mirror Engineer software — the takeoff engine is then an upgrade sold to an installed base, not a cold product sold to a stranger.
Your Property Warriors, live at yourpropertywarriors.com
Live — yourpropertywarriors.com. Not a template preview. The customer picks the job, picks a window, and it lands on the contractor’s crew board inside the same file.

What comes out of it

A priced estimate — Ellison Residence
A priced job. Every cost code on one sheet, sub-bids against his own quantities. This one totals $34,410 — and the same sheet now carries a $10,454,559.68 custom home, reconciled to the builder’s own workbook to the penny.
A printed sheet on the contractor's letterhead
On his letterhead. Every sheet the pack prints carries the contractor’s mark and contact, not ours.
A print-ready yard sign
Sign-shop ready. Yard signs and flyers in four formats, generated from the same file.

Five companies, one template

Each is the same engine with a different brand object dropped in — colours, mark, copy, trade, services. Building the sixth is a configuration, not a project.

Since this brief was written — 2 September 2026

One working session, on one real job. Nothing below is a projection; each line is a thing that now runs.

What changedWhy it matters to this raise
The estimating sheet ran a $10,454,559.68 custom home. Upland Development’s Cardon Ski House pre‑contract estimate — 94 lines, 64 base cost codes, 25 options, the sheet’s own 2%/5%/8% supervision, G&A and margin formulas.The sheet was previously shown on a $34k exterior job. A ten‑million‑dollar custom home is the market the takeoff engine is aimed at, and it is now demonstrated rather than described. The builder refuses to write the file unless the lines sum to the customer’s own workbook to the penny.
86 sub‑bid documents read straight out of the builder’s folder — 53 filed onto their cost‑code lines, 50 subcontractors registered with awarded and pending marked.The unglamorous half of estimating is filing. This is the part a contractor pays somebody to do by hand, and it is the part that makes the takeoff engine land on an installed base instead of a blank page.
One column that says what a bid includes — material, labour, tax, freight — and flags any bid carrying labour and tax in one number.Tax does not ride on labour, so a lump number with both in it cannot be checked until it is split. The sheet does not correct the number; it names the bids that owe a breakdown. And it reports a cost code where the material is bought and nobody bid the labour — a hole no total will ever show you.
A price database with real numbers in it: 228 items, 132 vendor quotes, 42 cost codes, filterable by who bid it.The item definition is universal — what a 4′‑0″ continuous footing is does not change between jobs. What a sub charged for one belongs to the builder who received the quote, and ships to that builder alone. That separation is what lets one database serve every customer without leaking any of them.
Measure → Price → Total is one loop. Quantities marked on a plan now reach the estimating sheet as quantities.Not one dollar moves on import. Money only moves when the estimator explicitly sets a rate — the discipline that makes a machine‑produced estimate defensible to the person who has to sign it.
Six owner’s manuals became one file of 32 KB.Measured before it was touched: strip the screenshots and the six were 99.8% identical, differing only by company name and two hex colours. Six parts doing one job is a defect generator. Each pack also lost about 3.2 MB. This is the same parts‑count discipline the hardware was built with, applied to the software.
Nothing ships without passing an automated render inspection.Four lanes — layout on four screen sizes, print at four paper sizes, another customer’s brand anywhere in the file, and text that cannot be read against its own background. A red tag stops the build. All three packs are green.
What this is not: revenue. The packs are built and in customers’ hands; a priced, repeatable sales motion is what the raise pays for. The claim here is that the product exists and works, not that it is yet a business.
The technology — why it wins

It reads the engineer’s own schedules. No one else does.

Drop a plan; the engine reads the engineer’s vector layers, auto-scales with no setup, paints the takeoff on the engineer’s own sheet, and drops out a bid-ready schedule & estimate. Today it does concrete foundation takeoff — built for concrete & foundation contractors and the estimators who bid them. The same engine then extends to framing, the other trades, and the general contractor’s full estimate.

2 Sep — it now teaches itself the vocabulary. There is no list of footing marks in the software and there never will be. A schedule on a sheet is a column of marks with rows beside it; find the column and the drawing has just told the engine what this engineer calls things. Every other place those words appear is a callout, and an editable object lands on it. Dropped on the Cardon ski house permit set it found four schedules it had never seen, placed 67 objects on one sheet, and matched every one to its own schedule row.

Why the gap is 44 against 29. Half the footing tags on that sheet are printed rotated ninety degrees, running along the footing lines. Standard PDF text extraction silently drops rotated text — it does not error, it just returns fewer tags. An estimator using a tool built that way gets a takeoff that is quietly a third short and nothing tells him. The engine reads both orientations, and it was checked mark by mark against the drawing before the number was used.

The asset sheet

What the investor steps into.

Real, built work — not a blank page. This raise is two pieces: the Mirror Engineer estimating software and the CFS forming-hardware & sales integration. And there’s real upside on deck: two U.S. patents are already granted and the CTBS hardware is designed and ready to manufacture. It isn’t sold in this deal — but doing this deal puts the investor first in line to invest in CTBS’s coming hardware & patents.

$2,000,000 to take the packs from five hand-built companies to a priced product with a sales motion, and to finish the takeoff engine that upgrades every one of them. The investor elects the structure: a 15% loan, or 20% equity with a Year 5–8 buyback ladder.

Where this sits. At $2.0M and pre-revenue, this is a seed-stage / angel raise — not private equity. We recommend the equity path (Option B): capital stays working in the business instead of pulling monthly debt service, and it aligns the investor with the upside. The 15% loan (Option A) is offered as the conservative alternative.

The trade contractor bidding TO a builder, and the sub or supplier selling INTO a job. Same doors, different catalog.
The precedent, and it is not a projection: EstimatorPRO sold 800+ units at $1,200 each, at one show, to contractors who bought on the spot — no subscription, no demo cycle. That is the price point this buyer has already proved he will pay.
Priced under the incumbents: Bluebeam $260–590 · PlanSwift $2,000/yr · Square Takeoff $1,699/yr · STACK ~$3,000 · Togal ~$3,588. Field-service shelf, for Light: Jobber $49–499/mo · Housecall Pro $79–329/mo · ServiceTitan $245–500 per tech per mo, plus $5,000–15,000 implementation. Re-checked against each seller’s own page.

Important — what this deal is and isn’t: This transaction conveys no ownership of Climate Tech Building Systems and does not include its hardware, patents or systems. The investor’s only connection to CTBS is a first right of participation in that separate, future venture, described in the term sheet below.
