Slot booking, members and apps for sports and leisure.

Tennis and padel clubs, gyms, associations, leisure centres: the same problem comes back, the problem of the slot. Who books, who pays, who turns up. We work with Les Pyramides, a private multi-activity club in Le Port-Marly, for whom we built the members-only online childcare booking. We are also building Rackts, a racket-sports platform that has not launched yet: we know the field from the inside, and we say so rather than presenting it as a delivered reference.

What is not working today, for most organisations.

Four situations we find at the clubs and centres that contact us.

The slot is booked by phone or in a notebook

The 7 p.m. court is booked twice, the 2 p.m. one stays empty because nobody saw it free up. Reception spends the day on the phone instead of welcoming people. An online schedule, visible to members and editable by reception, solves it in the first week.

Members live in a spreadsheet

Subscriptions, medical certificates, licences, reminders: it all sits in one file two people edit at the same time. At the start of the season, nobody knows who is up to date. A member database with online payment and automatic reminders replaces the spreadsheet and the manual chasing.

Payment happens at the counter

A slot booked but unpaid is a lost slot when the person does not turn up. Payment at booking, through Stripe, cuts no-shows and frees reception from the till.

The site talks about the club, not about the activity

“Beginner padel lessons Paris 15”, “indoor tennis court hire”: those searches each deserve a page, with the hours, the prices and the booking button. A site that only tells the club’s story is found by nobody.

What we do for a club or a centre.

Three workstreams, starting with the one that wastes the most time.

A website with booking inside it

One page per activity and per audience, prices written down, the schedule online and payment at booking. Reception edits the slots from a phone.

Website design

An app for members

Book, pay, cancel, find playing partners, from iOS and Android on a single Flutter codebase. We publish and maintain our own apps, Swapp and Georgia, through the same pipeline.

Mobile app

A membership management tool

Subscriptions, certificates, licences, automatic reminders, exports for the federation. Code and data in your name. What Rackts teaches us about the field, and what the Pyramides childcare service taught us about members-only booking, is in the quote.

Custom software

Projects delivered in this sector.

Rackts, our racket-sports platform, is in development and is not a client reference: we mention it for what it is, proof that we work this field.

Les Pyramides

A private multi-activity club in Le Port-Marly (Yvelines): tennis, padel, squash, golf, pickleball, pools, wellness. Delivered: the online childcare service, members only, at nurserie.les-pyramides.com.

Rackts, in development

A racket-sports platform, a studio product, registered trademark, not in production yet.

Frequently asked questions.

Do we need an app or is a website enough?

A site with booking is enough to start. An app is justified when members book several times a week and notifications matter.

Can you take over our member file?

Yes. Importing the existing file is part of the switchover, with a de-duplication pass.

Will Rackts be offered to our club?

That is the goal. In the meantime, we build what you need to measure, and that work feeds Rackts.

Who handles the payments?

Stripe, on an account in your name. The money arrives directly with you; we take no commission on slots.

Do you run a club, a gym, a centre?

Describe how slots and memberships are handled today. We reply within two working days.
