We built this because your sub won't download anything.
SubShare is the smallest possible tool for the most common workflow problem in construction: getting blueprints, lockbox codes, and site info onto a subcontractor's phone — without making them install, sign up, or remember a password.
Three things kept happening
- 1
A GC texts a lockbox code to 8 subs at 6:45 AM. By 9:30 AM, three of them have texted back asking for it again.
- 2
A sub shows up at the wrong address because the GC's job address is buried in a Gmail thread from four days ago.
- 3
A GC fires a sub mid-job and spends the evening worrying whether the sub will show up the next morning with a friend.
The construction software industry has Procore, Buildertrend, Fieldwire, PlanGrid, CompanyCam, and a dozen others. Every one of them is great at what it does. But every one of them requires the subcontractor to download something, sign up, remember a password, and navigate a UI built for office workers.
Subs don't do that. So GCs fall back to text messages, screenshots, and phone calls — and that's where the hours leak. SubShare exists for the leak.
Our principles
The sub never installs anything
A magic link in a text is the entire UX. If we ever need them to download an app, we've failed.
Revoke is one click
A sub gets fired and their link stops working before they reach the truck. No changed locks. No awkward calls.
Offline isn't optional
Plans need to load in basements, attics, and remote sites where signal disappears. We cache on first open.
Pricing is flat
$29/month. No per-seat. No upsells inside the app. The free tier covers most weekend warriors permanently.
Who we are
We're a small team of former tradespeople and software builders. We don't have a sales department. If something is broken or missing, it's on us — and you can usually reach the person who shipped the bug directly through the contact form.
The fastest way to reach us is the Contact page or [email protected]. If you're a GC and you'd like to talk through a specific workflow before you sign up, that's exactly the conversation we want to have.
SubShare is built and operated by SubShare App, an independent, EU-based team. Our data practices and the laws that govern us are spelled out in the Privacy Policy and Terms of Service.
