A Dutch software company for tennis
Serious software for serious tennis.
Contakt builds three focused things: one runs the club, one shows the stroke, and one asks whether technique can become a game. Each is described here exactly as far along as it is — nothing is sold before it works.
Every route is an email to a person, not a form. No account, cookie or mailing-list side effect.

The rule for this page
The most important fact about a product is how far along it is.
Most software sites hide maturity behind confident verbs. Contakt puts it first. The status word on each product is load-bearing — it names what exists, what still blocks use, and what we refuse to claim.
We show the product, state where it is, and make only claims the product can support.
The club keeps its relationship and data; the athlete keeps control of their footage.
The products · one honest register
Three different jobs. Each described exactly as far along as it is.
Same company and standard, deliberately separate products. Read each status line first — maturity is the most important fact on the card.
Run the club without running between systems.
Enrollment, memberships, courts, programmes, payments and parent communication in one operating record for commercial tennis parks, schools and clubs.
The working build is being proven against real club workflows before it is sold. A demo shows the product, not a deck.
Office, coach and member — three working role surfaces · synthetic records
Make the invisible part of the stroke visible.
An iPhone technique tool. Record or import footage, isolate the movement, and compare two strokes on one contact-aligned timeline.
The pre-release build has working local coaching flows. It is not on the App Store; footage stays on the phone unless its owner shares it.
Contact-aligned compare and joint angles — founder-recorded analysis
Can a stroke’s style become a game?
A separate consumer experiment for recreational racket-sport players. It records and reviews a controlled take, but it will only show a style match if the comparison technology earns it.
Today the normal player path deliberately shows no score. There is no public account, social service, purchase, reference catalogue or App Store release.
The honest gap: real-player feasibility and a rights-cleared reference must pass before a result can become a product claim.
Why one name holds three products
One word. Two kinds of contact.
Contakt is a play on contact. The technical work behind all three products comes back to the same idea.
The idea
Contact with the ball. Contact with the student.
Vision
The moment technique happens, read from video — grown from the founder’s thesis on reading strokes.
Academy
The whole club to run — lessons, courts, families and payments kept on one operating record.
Challenge
Can that same technical work become a game recreational players actually want to play?
How we work
Built for the moment the job gets real.
The same standard sits behind every product. It is what keeps three different maturities honest on one page.
Specific before broad
We make products for clear, high-consequence jobs rather than trying to be everything to every sports business.
Evidence over theatre
No imagined outcomes. We show the product, state where it is, and make claims the product can support.
Ownership stays with the customer
Academy is designed so the club keeps its relationship and operating data; its per-club payment route stays gated. The athlete keeps control of their footage and the choice to share it.
No tracking by default
This site has no cookies, analytics or trackers. Every contact route is a plain email to a person.
Where things stand
We release on gates, not dates.
Three status words carry the whole page. Each names what exists and what still blocks broader use.
How we describe readinessPublic status reviewed 19 July 2026.
Pre-launch
Built and being proven against real workflows. Production and company-control gates remain before it is sold.
iPhone beta
A pre-release build with working local flows and limits that stay visible. No App Store, cloud or delivery claim.
In research
A question tested with instruments and gates. No evidence means no ship — and no score until feasibility passes.
The founder
One person who lives both meanings.
Noah Cladera grew up in Mallorca with a racquet in his hand and is part Dutch — so building here is a homecoming. He studied computer science and AI at Vrije Universiteit Amsterdam, then coached across clubs in The Hague and Amsterdam.
Contact with the ball became Vision. Contact with the student became Academy. Challenge is the research question that grew from the same work. Contakt is a Dutch company of one, stated plainly because it is who a club, coach or research participant would be working with.
