Klu, the point-of-sale system keeping Thai weed shops from losing their minds
Meet the Thai startup helping dispensaries stay legal, organised, and ready to grow in a booming cannabis market

Thailand’s cannabis industry has grown like a weed. You can now get your favourite strain the same way you’d pick up oat milk or a new pair of sandals on your way somewhere else. Dispensaries have become as ordinary as coffee shops.
The problem is that very few of these dispensaries had the structure or tech to support serious growth. Most were started with good intentions and decent flowers, but not much else.
But Klu, a sleek little software system that sits behind the counter at some of Thailand’s best cannabis dispensaries, is here to help. It keeps inventory synced, sales tracked, and, most importantly, the government happy.
There’s trouble in (the green) paradise
The headlines for the cannabis business in Thailand might be filled with success stories, but according to Sagun Nagar, one-third of the brains behind Klu, the reality is far more nuanced.
“If there is a tourist inflow, we will see a rise in the industry. But as we see the downfall of tourism, it kind of goes down. So yes, the dispensaries, as I feel and as we are seeing in the market as well, are struggling.
Dispensaries who are running chains of seven, eight, twelve dispensaries are struggling because they have scaled quite rapidly, and they have no technology to support that kind of aggressive and expanding scale out there,” he explains.
For dispensary owners, the pressure is real. Many still rely on Excel sheets, juggling customer data, stock levels, and legal paperwork manually.
That’s why Sagun, along with Riccardo and Massimiliano, came up with Klu POS.

So, what is Klu POS?
Think of Klu as a cannabis dispensary’s sober best friend. It tracks inventory, auto-generates compliance reports, manages customer data, and lets you know when your best Indica strain is about to sell out. It does all this quietly from the back of an iPad. Plus, it’s fast. Start to operate in under an hour kind of fast.
“Our POS system helps them [cannabis dispensaries] get started in less than an hour. [This] is a process that used to be a two-day process… they can get live in like an hour or two and start selling immediately.
It’s not some lazy restaurant system being squished into a cannabis-shaped hole. It was built, line by line, for this market.
Klu now powers over 40 dispensaries in Thailand, including big names like Siam Green, The Joint, All Time High, and Library Samui.
How Klu helps with compliance
It’s easy to see how software can help with inventory, but how does Klu help with compliance?
“The Thai government expects dispensaries to keep a check on two things. Number one: where are they sourcing their product from? … They want to understand even 0.01 gram of it. How much they’re able to do that, that’s a completely different discussion altogether. But that’s the expectation.
“And the second set of information they want to know is: where are you selling this? Which is the customer information. At the end of every month, you have to submit that report in a specific format to the Thai government,” Sagun notes.
With Klu, you just input the sale and the system does the rest. Your reports are ready at the end of the month. Therefore,dispensary owners can focus on delivering great customer experiences.
And with the latest regulation report launched citing stricter rules in 40 days, we asked Sagun if the dispensaries could rely on Klu. He answered:
“From mandatory prescription checks and dosage controls to tracking GACP-certified sourcing and ensuring compliance with export restrictions, Klu can seamlessly adapt to these new requirements. By integrating features like medical certificate validation, controlled access to cannabis products, and real-time reporting aligned with government formats, Klu not only simplifies operations but also positions dispensaries to stay fully compliant without sacrificing efficiency or customer trust. We are dedicated to building and making the community stronger.”.
Designed for budtenders, built for scale
Klu’s interface is sleek and user-friendly, which means you don’t need a crash course to use it.
Budtenders get a fast, intuitive checkout system with integrated ID checks. On the other hand, multi-branch operators get a centralised dashboard where they can view sales, inventory, and customer data across all locations.
In addition, they can build tech based on what the dispensary needs. For example, Siam Green asked them to integrate their accounting software with Klu. “We built an API so that Zoho Books accounting software can now be integrated with [our] POS,” Sagun explains.
For smaller shops, it’s the same tech, just scaled down.
B2B marketplace, AI features, and more

Recently, the team at Klu launched a B2B marketplace where dispensaries can source cannabis directly from local growers. It’s a game-changer for transparency, quality control, and building sustainable supply chains.
“When we opened that market, we are now able to see where the traffic is coming to a B2B market. And we see a lot of traffic coming from outside Thailand. You know, traffic from Germany, traffic from Australia, traffic from Japan,” says Sagun.
This strategic move shows that there’s global demand for clean, high-quality, organically grown cannabis. And the good news is, Thai growers are producing at global standards already. The way Sagun sees it, Thai-grown cannabis could become an export powerhouse. That is, if the brands survive the current mess.
In addition to the B2B marketplace, the team is already working on integrating AI features to make the system even more intuitive. Imagine being able to ask your POS, “Which strains are underperforming this month?” and getting an answer instantly.
They’re also raising a pre-seed round to keep up with demand. “We have been growing fast. Last year, we’ve properly operated for some eight or nine months, but still, we saw a month-on-month average growth of around 22.7%. So we want to push that thing again,” he told us.
Klu might just be what the Thai cannabis industry needs
Sagun doesn’t claim to be a cannabis expert. “None of us know how to grow weed. We do not know the technicalities, the terpenes, or the CBDs. There are experts sitting out there. But we know something which they don’t know, which is technology,” he confesses.
As regulations tighten and the free-for-all phase winds down, the brands that will survive and thrive are the ones that understand it’s about structure and compliance. It’s about knowing your customers, delivering a consistent experience, and having the tools to grow sustainably.
“So many dispensaries gave us free weed, free joints. And that is what we are trying to come up and say: ‘Look, you gave us the best weed. We built the best technology for you. Just, just try it out, man,’” he says.
If you’re in the cannabis business and feeling the pressure, from compliance stress and inventory headaches to the chaos of multi-location management, it might be time to consider a system that was actually made for you.
“The Thai cannabis industry itself has a potential of $10 billion by 2028 or 2030,” says Sagun. But without infrastructure, all the good weed in the world won’t save the industry.
