Evidence layer · Construction

The proof was there
all along.

The independently verifiable evidence layer for construction projects. Site evidence scatters across inboxes and drives, so when a claim lands months later, it can't be pulled together in time.

The problem

When the claim lands, the proof is already scattered.

A dispute surfaces months after the work. The emails, photos, instructions and site conditions that prove your case existed all along, but they're spread across inboxes, phones and drives. Skilled people burn weeks reconstructing a record that should have been ready. Time runs out. Money is lost.

What it does

Capture and seal the record as it happens.

SiteSync is an independent evidence layer for construction projects. It captures site evidence (emails, photos, site conditions, notes and instructions) as it happens, and seals each item the moment it is captured, so the record is provably unaltered and tied to a point in time. It sits above the systems you already use, such as Aconex, Procore, Autodesk, SharePoint and email, without replacing them.

01

Capture and seal at the moment

Every item is sealed the instant it is captured. Nothing is added or edited after the fact.

02

Organise automatically

Forward an email to file it. Evidence sorts itself by project and topic, so it's there when you need it.

03

A verifiable pack in minutes

Produce a complete, independently verifiable evidence pack when a claim arrives, not weeks later.

04

Sits above your systems

Works with the tools you already run. Not another platform to log into and maintain.

Why it holds up

Verifiable by anyone, including the other side.

Cryptographic fingerprint at capture

Each item is sealed with a cryptographic fingerprint the moment it is captured.

Independent external timestamp

An independent timestamp fixes each item to a point in time, from a source outside our control.

Verifiable without trusting us

Anyone can verify the pack, including an opposing party, without trusting the vendor.

What this proves is precise: that a record is unaltered since capture and tied to a time. It does not claim to prove that an event happened as described. Dispute-grade evidence, honestly scoped.

Who it's for

Built for complex projects where the record matters.

Main contractors and construction managers on CHF 20–250M projects: pharma, data centres, complex fit-out, MEP-heavy work. Commercial directors, project directors, claims and risk teams who have seen how fast a good case falls apart when the proof can't be found.

Who's behind it

Built from the tools up.

SiteSync is built by someone with 24 years on site experience, from carpenter to senior superintendent to client representative, who got tired of watching good people lose claims, time and money they should have won, because the proof couldn't be found in time.

It's built the way site teams actually work, not the way software vendors wish they did.
