FOUNDING is a promotion code for Core only. You enter it on Stripe’s checkout screen (not a Mortar screen) when you subscribe to Core. The offer is 20% off Core for 12 months. Terms: first-time customers only, limited to the first 100, valid until 31 March 2027. Current Core prices (before the discount) are on the pricing page.
Steps
- Open Settings, then Billing. Press Subscribe on Core for the website, or the Core subscribe button on the website row.
- In the Subscribe for box, keep Core selected. Press the Core subscribe button. That opens Stripe checkout — a Stripe page, not a Mortar page.
- On Stripe checkout, press Add promotion code, enter FOUNDING, and apply it. Complete payment. Mortar brings you back to the website when checkout succeeds.
Checkout only opens for Core today. Pro is marked Launching soon on Billing. The button is Join the Pro waitlist. See plans and changing plan.
If it doesn't work
If checkout does not open, the message is "We couldn't open checkout just now — please try again, or email team@mortar.site."
If the code is rejected on checkout, the offer may have been used up, may have ended, or the account may not count as a first-time customer. Check the pricing page for the published terms, or email team@mortar.site.
If the website already has a subscription, Billing tells you to use Manage billing instead of opening a new checkout, so you cannot apply FOUNDING that way.
Common questions
Where do I type FOUNDING in the Mortar app?
You don’t. Open Core subscribe from Billing. Checkout is Stripe’s screen, not Mortar’s. Press Add promotion code there and enter FOUNDING.
Does FOUNDING cover Pro or Grow?
No. The offer is 20% off Core for 12 months. Pro checkout is not open. Grow is a separate add-on.
