7even

Software for people who sell their time.

7even designs, builds and runs its own products. The first one is called Kairos.

We don't sell hours. We sell product.

7even is a software product studio: we design, build, ship and operate. The same people who write the code answer the people who use it.

Our own products, not client projects
Every product starts from a problem we understood from the inside, and keeps evolving after it ships. Nobody hands it over and disappears.
Run by the people who built it
Deploy, database, queues, notifications and support. There is no step where the software becomes somebody else's problem.
Built here, for the market here
Prices in reais, copy in Portuguese, the right time zone and the right holidays. The business using it translates nothing.

How it is built

Cloud
Google Cloud in the São Paulo region. The APIs run on Cloud Run, and everything web is static on Firebase Hosting.
Data
Managed PostgreSQL, also in São Paulo. Versioned migrations, and the service refuses to start against a stale database.
Apps
Beyond the web, apps for iOS and Android: one for the owner, one for whoever does the work, one for the end client.
Billing
Subscriptions and invoices through Stripe, with receipts and PDFs rendered by the platform itself.

The product

Appointments, classes and events. One account.

Kairos serves anyone who sells their own time: the one client slot, the class that repeats every week, and the event with tickets and check-in at the door.

One on one

One client, one slot.

Salon, clinic, studio, practice. Every professional with their own calendar, their own rules and their own day. It confirms on its own, or only after your ok.

Teaching a class

One hour, the whole class.

Gym, school, pilates, languages. Each slot is a class with counted seats, and each student is a booking inside it.

Moved the class? Everyone moves with it, or you move a single student.

Ticketed events

Sold, admitted.

Show, workshop, conference, fair. The ticket comes as a PDF with a signed QR code, and check-in at the door runs on the phone of whoever is receiving, with no login.
