The client portal where
the work gets signed off.

Keystone gives every client a private workspace to follow the work, talk it through, and approve it from their phone. The back-and-forth lives in one place, instead of scattered across email.

The Keystone board: a client’s work in columns from draft to published.
The problem

Approvals go to die in email.

A deliverable goes out as an attachment. The reply lands three days later, buried under a forwarded thread, with the actual change request somewhere in the middle of it. Nobody is quite sure which version is final. The work sits and waits on a sign-off that is hard to even find.

Keystone takes that whole exchange out of the inbox and puts it somewhere it can close.

I

Watch the work move.

Every piece of client work sits on one board: Draft, Needs your OK, Changes, Approved, Published. Move a card and both sides see exactly where it stands. The status-update email stops being something either of you has to send.

II

They approve from the phone.

A push notification lands. Your client opens their workspace, sees the one thing waiting on them, and taps approve. No login to hunt for, no thread to dig through. It works the same on the train as it does at a desk.

III

The whole schedule, in view.

See what is going out and when. Scheduled work sits on the calendar with its status, so a piece never slips through the gap between “almost done” and “live”.

The Keystone calendar: a month view with scheduled work and its status on each day.

Why it exists

“I built Keystone because client work kept dying in my own inbox. Drafts, approvals, the long back-and-forth, all scattered across email. This is the tool I wanted: one quiet place where the work gets seen, talked through, and signed off.”

Questions

Before you start.

Who is Keystone for?

Studios, consultants, agencies, and freelancers who hand finished work to clients and need a clean, on-the-record sign-off instead of an email thread.

Can my clients really use it on a phone?

Yes. Reviewing and approving are built for mobile first, in a couple of taps. They can install it to the home screen and get notified when something needs them.

Is each client’s work kept separate?

Completely. Isolation is the point. One workspace has no way to see, count, or reach into another. A client only ever sees their own.

How does billing work?

You can cancel any time, and your access stays open until the end of the period you have paid for. Billing is handled by a third-party payment provider, shown to you at checkout.

What if it is not for me?

You have 14 days, no questions asked. If Keystone is not right, ask for a full refund inside two weeks of your first payment and you get it back.

Put your client work somewhere it can close.
