Important dates should not depend on someone remembering.

DueHarbor is building an expiration and renewal command center for growing teams—one place to make critical dates visible, owned, and ready for action.

Join the waitlist

Built for the person who keeps the spreadsheet alive.

Operations, IT, finance, procurement, facilities, HR, and admin teams managing important dates without a dedicated system.

The problem

Scattered reminders create invisible risk.

Critical dates live across spreadsheets, calendars, and inboxes.
Ownership gets fuzzy when work changes hands.
A reminder exists, but nobody can tell whether it will reach the right person.

The DueHarbor idea

Protection you can explain at a glance.

In DueHarbor, an Item is Protected only when it has a confirmed governing date, an owner, an active reminder sequence, and at least one valid enabled recipient.

A date you can trust

Confirm the governing date and what it means before a reminder depends on it.

Clear responsibility

Keep an accountable owner and enabled recipients visible alongside the deadline.

Honest Protection

Know when an Item has every required safeguard—and exactly what is still missing.

Useful history

Preserve decisions and prior cycles so the next renewal starts with context.

One simple workflow

From scattered date to accountable outcome.

Contracts, licenses, insurance, certifications, and other obligations follow the same focused path instead of becoming separate systems.
