Sitewell Series A

Construction tech pitch deck measured in defects per site

A construction tech pitch deck has to prove the software changes what happens on site, because builders do not pay for apps, they pay to avoid rework. Sitewell, an invented Brisbane inspection product, shows rework items per site falling 34 percent over eight months while logged defects more than double.

SITEWELL

SERIES A · MAY 2027 · BRISBANE

Catch the defect on Tuesday, not at handover

Site inspection software for residential and mid-rise builders.

Slide 1 · cover · Put the outcome a builder pays for, fewer rework items, on the cover instead of the software category.

The problem

Defects are found late because inspections live on paper and in photos on personal phones. By the time a list reaches the trade, the wall is lined and the fix is rework.

Found late

Across our customers, two thirds of rework items were visible at an earlier stage that nobody inspected.

Lost in phones

Site managers take hundreds of photos a week. Almost none reach the trade who has to fix the problem.

Paid twice

An average rework item costs a builder about 1,850 dollars in labour, materials and delay.

Slide 2 · intro · Rework as the cost nobody budgets for, in three facts drawn from the customer base.

What Sitewell does

A checklist walk on a phone, built from the stage of the build, that sends each defect straight to the trade who owns it.

Stage checklists

Pre slab, frame, pre lining and fit off, with the items that most often fail at that stage.

Photo pinned to a plan

Each defect carries a photo and a pin on the drawing, so the trade finds it.

Sent to the trade

The defect goes to the subcontractor by text message with a due date.

Closed with proof

The trade uploads a fix photo. The site manager accepts or rejects it on the next walk.

Handover pack

Every inspection and fix in one PDF for the client and the certifier.

The site manager

Dean runs two townhouse sites for a 40 home a year builder. He walks each site twice a day and answers to a construction manager.

Says

"I found the same missing nogging three times. Every time the plasterer was already booked."

Thinks

Another app means more typing at the end of the day. It has to be faster than the notebook in his pocket.

Does

Walks the frame stage list on Tuesday morning, pins nine defects and has them with the carpenter before smoko.

Feels

Less exposed at handover. The client walk now finds a short list rather than a page of surprises.

Slide by slide

Slide one puts the outcome on the cover: catch the defect on Tuesday, not at handover. Slide two states why defects are found late, with three facts from the customer base. Slide three describes the product in five rows a site manager would recognise. Slide four gives sites, the rework reduction and ARR with how each was measured. Slide five charts defects and rework by month. Slide six is the site manager. Slide seven compares one inspection on paper and on Sitewell. Slide eight is per project pricing in three bands. Slide nine is the six million dollar ask. Slide ten offers a site walk and the rework data.

How to adapt this deck

A product for commercial head contractors rather than home builders should replace the site manager with the project engineer and price per project value rather than per site. A safety or compliance product swaps rework items for incidents or notices per site and adds the relevant regulator to the problem slide. A scheduling or procurement tool should keep the two series chart but plot what it changes, such as days of delay against tasks scheduled, because the mechanism matters more than the outcome alone.

What construction investors ask for

The Get It Right Initiative published the research on the cost of avoidable errors in construction, and it is the figure most investors in the category already have in mind when they hear the word rework. They then ask whether a product changes behaviour on site or only records it. This deck answers with the per site chart and the inspection comparison. Safe Work Australia publishes the construction work health and safety material a builder will expect any inspection tool to fit around.

What makes this deck work

The chart shows the mechanism

Slide five plots defects logged rising from 18 to 41 per site while rework items fall from 12 to 7.9. Two series on one chart show why rework falls: problems are caught at an earlier stage, not hidden. A single falling line would invite the opposite reading.

ARR reconciles to the price bands

Slide eight puts 680 sites at 149 dollars, 360 at 249 and 60 at 449 a month. That is about 218,000 dollars a month, or 2.6 million dollars a year, the ARR on slide four, which also prints the average of about 198 dollars a site.

The persona is the daily user

Slide six describes the site manager, not the builder who pays, because a tool the site manager ignores never reaches the budget. His quote about a missing nogging found three times is the problem the whole deck is built on.

Questions people ask

What metric should a construction software deck lead with?

The site outcome the builder pays to avoid, measured per site. For inspection software that is rework items; for safety software it is incidents; for scheduling it is days of delay. Usage figures like inspections logged come second, as evidence of how the outcome was achieved.

How do I show that defects fell without looking like fewer were recorded?

Plot defects logged and rework items on the same chart. If logged defects rise while rework falls, problems are being caught earlier. This deck shows 18 rising to 41 logged and 12 falling to 7.9 rework items per site over eight months.

Should construction software be priced per user or per project?

Builders think in projects, and trades and site staff change on every job, so per project or per site pricing usually fits better than seats. Sitewell bands the price by contract value and stops billing at practical completion, which removes the objection about paying for finished jobs.

Who should the persona slide describe in a contech deck?

The person who uses the product every day, usually the site manager or supervisor. The buyer may be a construction manager or owner, but adoption fails on site first. Describe what the user says, thinks, does and feels on a real inspection day.

How many slides should a construction tech pitch deck be?

Ten works for a Series A. Keep site photos and feature lists for the appendix. If time is short, show the cover, the rework chart, the pricing bands and the ask. The free plan generates up to six slides, enough for that short version.

Can I add photos from real sites to this deck?

Yes. Image slots accept uploaded jpeg, png, webp or gif files, and the AI can also generate images, though generated building sites will not show your real product. This example uses no photos at all, so every slide is about a number or a decision.
