The problem
Your renovation breaks in the same four places.
None of them is a surprise on the day it happens. Each one is an argument about what was done, and when, that nobody can settle because the record lives in a group chat.
Built for Singapore interior designers
Take on the next project without another site visit.
How many times a week do you go down just to check? Your subcontractors send photos instead. You check them from wherever you are.
Free through the 2026 pilot. No payment details. Data stored in Singapore.
Demo account. Fictional project, fictional firms, AI-generated sample photos.
01 Where it breaks
Where it breaks
-
01 Group chat chaos
Group chats work for three jobs and collapse at eight
One group per project, four to fifteen projects running at once. What was agreed sits somewhere in the scroll, and the claims live in a spreadsheet nobody has opened since Tuesday.
-
02 Nobody checked
Waterproofing tiled over before it dried
Tile over waterproofing that has not dried and the room comes out again. Our own estimate from Singapore rework quotes puts that at S$3,000 to S$6,000.
-
03 Off-site work
Carpentry vanishes for two to four weeks
Fabrication happens off site, typically two to four weeks, and uses no site labour. It drops out of most schedules and then overruns the job.
-
04 Client finds out first
962 complaints against renovation contractors in 2024, the highest of any sector, with S$728,000 lost in prepayments.

02 How it works
One loop, four steps, shown in the real product.
Photos leave site. You check them against what that subcontractor owes. Your check is what lets the next one start, once anything wet has dried. Every screen below is the product, on a demonstration job.
01 On site
Your subcontractor sends photos
Photos and a voice note against the checklist for that subcontractor, timestamped, saved to the phone first so one bar of signal is enough. No account to create, nothing to download.
02 In the office
You check it against what that subcontractor owes
Four photos, the checklist for waterproofing, and the two subcontractors waiting on this one piece of work.
03 Your check
Your check starts the drying time and lets the next one start
Nobody ticks a box to say it is done. Your check is the only thing that moves the job, or it goes back for rework with a reason your subcontractor can act on.
04 The next morning
Nothing is waiting on you
What is late, and what that late piece drags with it, is on one screen before you get in the car.

03 What it does
Six things it already does. Every screen below is real.
Every label below is text the product prints. Nothing here is a mockup of something planned.
-
What is blocked, and by what
The order is held by photos, not by someone's word in a group chat.
The only thing that moves it
-
A wrong call can be corrected, on the record
Undo a check and the reason is kept with it, and whatever it let start is told to hold.
-
Each subcontractor owes a specific list
Not “done”. Floor wide, wall-floor junction, floor trap corner, wall to 1.8 m.
-
Nobody assigned is something you can see
Not a thing you find out on the day.
-
A morning with nothing waiting
The empty state is the product working, not a screen with no data.
-
The whole job, as it actually stands
Verified, in progress, late and still to come, by area, against today.

04 Built for Singapore
The rules are already in the plan.
Generic construction software reads as foreign here. Pick HDB resale and the job arrives with the rules below applied as defaults.
-
HDB
HDB rules as defaults
Noisy work on weekdays only, none on Sundays or public holidays. Hacking capped at three consecutive days. Permit validity tracked, with renewal added to the plan as a task before it lapses.
HDB's published rules, applied as defaults. Always check the current HDB guidelines.
-
Condo
Condo and MCST hours per building
Working hours set per building, because they genuinely differ. Lift bookings treated as the finite shared resource they are.
Set from the by-laws you give us for that building.
-
Responsibility
You stay the registered contractor
HDB requires the permit to be applied for by a contractor on its Directory of Renovation Contractors, which for most design-and-build firms is the firm itself.
StampedID tracks these rules against your schedule. It does not certify anything and it does not deal with your client's money.
05 Indicative pricing
By projects running, not people in the office.
Subcontractors are free on every plan today; they join from a link, no account to create.
-
Foundation
S$149/month
Up to 4 projects at once
Planning, photo records, your checks, and the HDB rules.
-
Most firms
Studio
S$349/month
Up to 10 projects at once
Adds condo and MCST hours per building, and permit renewal tracked as a task in the plan.

Planned before full launch: WhatsApp for subcontractors, exportable records, a client-facing progress view and API access.
- Subcontractors free on every plan today
- No payment details during the pilot
- Founding rate for firms that reach handover
All prices in Singapore dollars. Prices are indicative and may change before full launch. Pilot firms that take one project through to handover keep a founding rate: the Studio tier at S$119 a month for 24 months.
We want a few interior design firms to build this with us.
Five to eight interior design firms in Singapore, one real project each, free through 2026. Twenty-five minutes at your office: we show you how it works on your own job, and you tell us where it does not fit. The pilot measures one thing: the trips you stop making.
