See the dance workflowStill running on the starter kit?
A calendar, a spreadsheet, and a group chat. It's the unofficial starter kit for every independent studio — and it takes you surprisingly far. Until it doesn't.
Imagine starting your week already knowing who's coming, who's paid, and where there's still space. No cross-referencing between calendars, group chats, and spreadsheets. No chasing. Just teaching.
That's what clssrm is built for.
Keep the weekly schedule and student records together, so you can focus on teaching.
All in one place
Not a marketplace. Not a generic calendar. A focused operations tool for class-based businesses.
See recurring classes, instructors, and available places in a weekly studio timetable.
Rosters, bookings, and contact info tied together. No more cross-referencing spreadsheets.
Record money collected elsewhere, with amounts, payment methods, dates, and notes beside each student.
Add students to specific class dates, check capacity, and mark attendance after class.
Invite staff with seat-based access. Everyone sees the same schedule.
Set weekly class times once. Each date has its own roster without copying a spreadsheet.
In their words
Early customers share what changed when their weekly operations moved into one place.
“I spent years getting lost in Excel, Google Sheets, and every custom solution you can think of. Having one dedicated tool to manage class availability and student payments has simplified my day-to-day work, so I can focus on other aspects of the studio.”

“clssrm changed how we run the studio. Before, a shared Google Calendar and countless Excel sheets made it hard to track class availability, pending payments, and cancellations. Now everything runs seamlessly, and our Pilates instructors can manage their own class availability.”

Our story
We've spent years as students — pottery wheels, pilates reformers, yoga mats. Along the way we kept noticing the same thing: talented instructors buried in spreadsheets and group chats just to keep their week organized.
We talked to studio owners we know personally. The story was always the same — passionate about teaching, stretched thin by admin. So we started building the tool they kept describing: one calm workspace for the weekly schedule, bookings, and payments.
We're working closely with real studios to get every detail right. No venture capital rush, no feature bloat — just a focused tool that does what you actually need.
Start your free 1-month trial. No credit card, no commitment — just a calmer way to run your studio.
