Your members,
for life.

mettle helps you notice who’s fading and celebrate who keeps showing up, and it handles the admin in between.

Meet Mike.
He almost quit.

He stops showing up

Mike Reyes

At risk

Three visits a week, then nothing for two. mettle flags the gap.

Day 2

You send a real offer

Open Mat Week

Exciting offers, not guilt trips. mettle delivers and tracks them.

Day 4

He walks back in

Still here. And his sister just joined.

That’s one loop. mettle runs a few more, but we’d rather show you than list them.

The basics, handled.

The paperwork, in one place.

Common questions

What happens after I request access?

We email you when there is a spot. Until then, nothing: no calls, no newsletter.

Where does my members' money go?

Straight to your own Stripe account. mettle never holds it, card details never touch our servers, and receipts carry your studio's name.

Do my members need to download anything?

No. Members sign up, sign and pay in their phone's browser, and check in on the tablet at your door.

What do I need at the front door?

A tablet with a browser. Pair it once with a six-character code, and it opens check-in before each session on its own.

We open spots for a few new studios, schools and clubs at a time.
