Our first product

Ulumi runs the front desk of a small studio.

Schedules, bookings, check-in, class packages and payments for yoga, pilates and dance studios. Built for the owner who is also the instructor, and who would rather be teaching than doing admin.

Get paid, your way

Card, Apple Pay, Venmo, Zelle or Cash App. Every payment lands in a clean daily history you can trust.

Software should lower the noise.

Three rules we hold ourselves to on every product we ship.

01

One person, whole business

We design for the owner who is also the instructor, the front desk and the bookkeeper. If it needs a manual, we simplify it.

02

Phone first

The real work happens between classes, standing up. Every screen is built for a thumb before it is built for a desk.

03

Your data stays yours

Students and payments belong to the studio. We collect what we need, protect it, and never sell it.

“The best software is the kind that never needs a demo call.”
