Stupa and D-Joy Make Vietnam Pickleball’s Tech Test Bed

The short answer: Stupa Sports will supply technology for D-Joy Pickleball Tour Leg 3 in Ho Chi Minh City from 9 to 13 September and the Vietnam Masters from 24 to 29 November, with a memorandum covering D-Joy events in 2027. D-Joy used Stupa’s AI statistics and a 9–11 camera video review system at Leg 2. Vietnam is building courts, players, broadcasting and officiating at the same time.

Stupa Sports is expanding its technology partnership with D-Joy Pickleball across Vietnam, bringing decision review, live analytics and broadcast data to this week’s D-Joy Tour and November’s Vietnam Masters. But the bigger story may be where all of this is happening.

There is a version of the story about Stupa Sports and D-Joy Pickleball that begins with artificial intelligence.

It is probably the least interesting version.

AI-assisted officiating, live performance data and three-dimensional broadcast graphics will all form part of the technology operation when the D-Joy Pickleball Tour returns to Ho Chi Minh City this week.

Stupa and D-Joy have also extended their relationship beyond September. The company is due to work at the Vietnam Masters in November, while a memorandum of understanding between the organisations covers further D-Joy events during 2027.

That makes Tuesday’s announcement more interesting than another sports technology partnership.

Because the important question is not really what Stupa is bringing to Vietnam.

It is why Vietnam is becoming such a natural place to use it.

Over the past year, the country has forced itself towards the centre of international pickleball through players, crowds, tournaments and an increasingly serious competitive ecosystem. WPM has already followed the depth emerging beneath Vietnam’s leading players, while last week’s World Cup in Da Nang supplied its most visible demonstration yet.

Three Vietnamese men reached the professional singles semi-finals. Lý Hoàng Nam appeared in four finals on the closing Sunday. The host nation eventually reached the Open team final against the United States.

There is now another part of that development taking place with considerably less international attention.

Vietnam is starting to look like one of the places where the infrastructure around professional pickleball can be built and tested at speed.

Not just somewhere to play the game.

Somewhere to build the machinery around it.

Stupa sports and D-joy are moving beyond a trial

Stupa Sports and D-Joy are not beginning from zero.

At the second leg of the D-Joy Pickleball Tour in June, the technology company supplied AI-assisted 2D and 3D statistics and broadcast graphics alongside livestreaming.

The tournament also used what organisers described as an automatic VAR system built around between nine and 11 ultra-slow-motion cameras positioned around the court. The system was designed to process disputed ball trajectories and present the result without requiring a separate video referee to inspect conventional replay footage.

That technology was part of a wider professional operation which also included DUPR integration and APP international referee Byron Freso as chief referee. More than 1,500 event registrations were recorded at Leg 2, according to reports from the tournament. TTC Group reported on the technology deployment here.

That distinction matters.

This week’s agreement does not mark the arrival of technology at D-Joy.

It suggests an experiment is becoming part of the operating model.

Stupa will now provide technology for D-Joy Pickleball Tour Leg 3, which runs from 9–13 September in Ho Chi Minh City, before returning for the D-Joy Vietnam Masters from 24–29 November.

The organisations have also signed an agreement covering continued technology collaboration at D-Joy events during 2027.

The package brings together three areas professional pickleball is still trying to solve.

Officiating. Performance information. Broadcasting.

For officials, that means technology capable of assisting with disputed decisions.

For players and coaches, it means moving beyond a final score towards information about what actually happened during a match.

For broadcasters, it means turning some of that information into graphics and analysis that can help explain the sport rather than merely display it.

None of those ideas is revolutionary in established professional sport.

Their significance in pickleball is precisely that they are being developed while much of the professional game around them is still being built.

From Mumbai to Birmingham to Ho Chi Minh City

Vietnam is not Stupa’s first pickleball laboratory.

Earlier this year the company worked as a data technology partner at the World Pickleball League in Mumbai, where its systems included decision review and replay technology.

Then came Birmingham.

In August, Stupa began a three-year relationship with Pickleball England as its data and technology partner for the English Open.

WPM examined the project before the tournament in The English Open Has 60 Courts. Its Technological Future Will Be Tested on Two, when the central question was not whether the technology sounded impressive on paper but whether it would work when players started challenging real decisions.

It did get tested.

The English Open eventually attracted 3,509 registered players and operated across 62 courts at Birmingham’s NEC, according to Pickleball England.

Stupa’s Decision Review System was used on the championship courts. During one match, a player challenged a call at 14–14 on match point and the review overturned the original decision.

That is a small moment in a six-day tournament.

It is also exactly why the technology matters.

A review system stops being a presentation when somebody’s match depends upon it.

Mumbai, Birmingham and Ho Chi Minh City are very different environments. One is a professional franchise league. One is an enormous participation tournament with elite competition sitting inside it. One is part of a rapidly expanding Vietnamese tournament and facility ecosystem.

The common question is the same.

What does pickleball need around the court once the consequences on the court become serious?

D-joy leg 3 gives the technology another test

D-Joy Pickleball Tour Leg 3 begins on Wednesday at D-Joy Pickleball Nam Saigon and runs until Sunday.

The tournament carries a reported VND3 billion prize pool across its amateur and professional competition, with the professional programme building towards Sunday’s finals.

It is also the final tour leg on D-Joy’s road towards the Vietnam Masters later this year.

The scale of D-Joy’s wider operation is significant. The partnership announcement describes the organisation as operating a club, academy and tournament business in Ho Chi Minh City, with 76 courts across three locations, including a 52-court cluster.

Those facility figures come from the organisations themselves, but even without them the broader point is increasingly difficult to miss.

Once tournaments grow, the operating problem grows with them.

Matches have to be scheduled. Results have to move quickly. Officials require support. Player information has to remain coherent. Livestreams need usable data. Broadcasters need graphics and statistics capable of turning a succession of rallies into a sport viewers can understand rather than simply watch.

And contested decisions begin to matter more.

Why pickleball needs better decision review

Pickleball has spent years living with a peculiar contradiction.

At recreational level, players routinely make their own line calls. The game’s culture has been shaped partly by that informality.

At professional level, however, prize money, ranking points, contracts and sometimes careers can depend upon balls travelling close to a line at speeds where certainty is not always possible.

The sport has responded with referees, replay, challenges and different forms of video review.

What it does not yet possess is one universally adopted technological answer comparable with the systems television audiences have become accustomed to seeing in tennis.

That is an important distinction when companies use terms such as AI-powered officiating.

The useful question is not whether artificial intelligence sounds advanced.

It is whether the system reaches the correct decision quickly, consistently and at a cost organisers can justify.

Does it work under tournament pressure?

Can players understand it?

Can officials trust it?

Can spectators see why a decision has changed?

Can an organiser afford to put it on more than one showcase court?

Those are much harder questions.

They are also the ones that determine whether a technology eventually becomes infrastructure.

Pickleball’s next race is about infrastructure

For much of pickleball’s international expansion, success has been measured through participation.

How many players?

How many courts?

How many countries?

Those numbers still matter. Increasingly, they tell only part of the story.

A country can have thousands of players without sophisticated tournament operations. It can build courts without producing compelling television. It can stage professional competition without collecting useful statistics. It can attract spectators without possessing the systems required to turn those spectators into a sustainable broadcast audience.

The next phase of international pickleball therefore involves another contest entirely.

Infrastructure.

Tournament software. Officiating systems. Player data. Livestreaming. Broadcast production. Statistics. Distribution.

They are less immediately exciting than announcing another 50 courts.

Collectively, they help determine whether professional pickleball looks like a recreational game being streamed or a sport being broadcast.

Vietnam has the advantage of building late

Vietnam has one potentially important advantage in that race.

It does not have decades of inherited pickleball infrastructure to replace.

North American pickleball largely developed from the bottom upwards. Recreation centres, retirement communities, municipal facilities, converted tennis courts and private clubs created an enormous player population. Professional tours, broadcasters, sponsors and technology companies then began constructing systems around something that already existed.

Vietnam’s path is different.

Large dedicated facilities, ambitious tournaments, professional players, international competition, commercial investment and technology are appearing within a much shorter period.

That was visible at the World Cup in Da Nang, where Vietnam’s competitive depth became one of the defining stories of the tournament. WPM watched the hosts survive consecutive Final Battles before reaching the semi-finals, while the professional events demonstrated just how many Vietnamese players can now compete against established international opposition.

There are risks to developing this quickly.

Infrastructure can be built before anybody knows whether demand is sustainable. Technology can be adopted because it looks sophisticated rather than because it solves a genuine problem. A sport can spend money making itself appear professional before developing the audience and commercial revenues required to support professional economics.

But newer markets also have an opportunity.

They do not necessarily have to retrace every step taken by the countries that arrived first.

Sometimes they can skip one.

Technology still has to prove itself

That is why what happens at D-Joy matters beyond whether a disputed ball is ultimately shown as in or out.

Video review has to prove it can settle decisions without repeatedly interrupting the rhythm of a match.

Performance analytics have to produce information that coaches and players actually use.

Broadcast statistics need to reveal something a viewer could not already see.

And eventually the economics have to work.

A system that functions brilliantly on a championship court but is too expensive to deploy anywhere else is not yet infrastructure.

It is a demonstration.

That difference matters particularly in pickleball, where the sport’s enormous participation base can sometimes disguise how young its professional structures remain.

Stupa itself operates well beyond pickleball. Its platforms cover competition management, scoring, streaming, statistics, graphics and review systems across sports including table tennis, badminton, tennis and padel.

That wider experience matters because many of pickleball’s current problems are not unique to pickleball.

Sports have always needed to decide how much technology improves a contest before it begins interfering with it.

Pickleball is simply reaching that discussion remarkably quickly.

What Vietnam can tell the Rest of pickleball

The Stupa-D-Joy agreement does not prove that artificial intelligence is about to transform pickleball.

It does not prove that one review system will become the game’s global standard.

Nor should a technology partnership be mistaken for evidence that every element of Vietnam’s professional pickleball economy is already mature.

What it provides is another live experiment.

Mumbai offered one in a professional league.

Birmingham offered another at a 3,509-player tournament spread across 62 courts.

Ho Chi Minh City now offers one inside one of international pickleball’s most interesting emerging environments.

The important questions will come afterwards.

Did officials trust the review system?

Did players use the data?

Did broadcasters make better television with it?

Did spectators understand more?

Could organisers afford to do it again?

Those answers matter considerably more than whether the technology carries an AI label.

For much of pickleball’s international expansion, emerging countries have been judged according to how quickly they can catch the United States.

That may eventually become the wrong way to look at it.

Vietnam is still learning from countries that built pickleball before it.

But in some parts of the sport, it is also getting the opportunity to build the next version first.
