Siteloop helps constructors eliminate wasted time and resources for smarter, more profitable projects.

Collaborate for growth

Many things slow down delivery on construction projects. Teams run late causing a chain of delays to other trades. Incorrect information causes expensive remedial work. Problems like these can jeopardise profits and damage a company’s reputation.

Improve delivery and reputation

Siteloop solves this by making collaboration fast and natural. Place all of your lead subcontractors into a group and keep them aware of progress.

Avoid mistakes by easily sharing the latest drawings and specs. When they change, Siteloop ensures that everyone sees the most current version.

Making Collaboration simple

With group messaging similar to WhatsApp at its core, Siteloop promotes naturally fast-paced messaging between groups for easy and efficient collaboration. And you can create, allocate and track tasks.

Simple useful reports

Share documents, track and manage tasks. See at a glance how each of your sites are doing. Create reports across all of your projects. Rank your subcontractors by their performance.


Siteloop is built with an open architecture made for multiple integrations. So whether you already use Dropbox, Microsoft Project or any other software, we can build integrations to allow simpler working for you and your teams.
