Walk through any Thai city and the entrepreneurial spirit is impossible to miss. Street vendors, family-run shops, independent cafés, nail salons, hair salons, Thai massage parlours — people here are not afraid to start something. Ask a group of Thai friends what they want to do with their lives, and a sizeable portion will say they want to own a business. That instinct is real, and it matters.

But when the conversation shifts from entrepreneurship to deep-tech startups — the kind that build globally scalable platforms, disruptive software, or frontier-technology products — the picture changes dramatically. And understanding why requires looking beyond Thailand's borders.

I work in solar energy conversion — specifically the science of turning raw sunlight into useful, storable, transmittable power. One lesson that field teaches you quickly: energy potential and energy output are not the same thing. You can have abundant sunlight hitting a surface all day, and still produce almost nothing useful if the conversion system is inefficient, poorly designed, or simply missing. Thailand's startup problem feels exactly like this. The entrepreneurial energy is abundant. The conversion infrastructure is not.

A Tech Wave That AI Is Now Washing Away
Thailand did experience a startup wave. For a stretch, B2B technology companies found a viable niche: building backend systems, custom platforms, and digital infrastructure for Thai enterprises that lacked in-house technical capacity. It worked — for a while.

Then AI arrived. As large language models and AI-powered development tools matured, the calculus for businesses changed. Why outsource your backend to a local startup when off-the-shelf AI tools can handle much of that work faster and cheaper? Many Thai tech startups that built their model on being the technical partner for non-technical businesses now find that their core value proposition has been disrupted from underneath them.

This is not a Thai problem alone — but it lands harder in ecosystems that never made the leap from service-based tech to product-based, research-driven innovation. Thailand's startup ecosystem is ranked 53rd globally by StartupBlink in 2025, with roughly US19 million in total startup funding tracked. That is a modest number for a country of 72 million people with a GDP of over US26 billion.

Three Countries, Three Different Problems
To understand what Thailand is missing, it helps to look at three very different models.

Singapore has built one of the world's strongest startup ecosystems — ranked 4th globally — with US.73 billion in tracked startup funding despite a population of only 6 million people. The key is structure: government-backed investment vehicles, deep-tech accelerators, and institutional connectivity to global capital. But Singapore's very success creates a different constraint. High living costs and strong career alternatives mean individuals have a great deal to lose by betting on a startup. The ecosystem is ready; the personal risk calculus is complicated. And because the domestic market is tiny, every Singapore founder knows from day one that their company must be built for the world, not just the island.

Japan presents a cautionary tale of risk aversion without the offsetting ecosystem strength. Despite being a technological powerhouse in manufacturing and engineering, Japan has struggled to produce globally competitive tech startups at scale. A culture that prizes stability, seniority, and retirement security means that entrepreneurial instinct — though not absent — faces strong social headwinds. The result is a country with deep technical capability but relatively thin startup output.

The United States works for a different reason entirely: sheer scale. Not everyone in America is a risk-taker. But with 340 million people, a GDP approaching US9 trillion, and a domestic market large enough to build a global-scale company without leaving home, even a small fraction of bold founders can produce extraordinary results. The US is the world's startup powerhouse not because Americans are uniquely brave, but because the math of scale and capital density is simply unmatched.

Thailand's Real Problem: Conversion, Not Courage
This comparison leads to an uncomfortable but important reframe: Thailand's challenge is not a lack of entrepreneurial courage. It is a lack of conversion infrastructure.

In solar energy systems, we talk about conversion efficiency — the percentage of incoming energy that actually becomes useful output. A poorly designed system wastes most of what hits it, not because the sun shines any less brightly, but because the mechanisms to capture, convert, and transmit that energy are inadequate. Thailand's startup ecosystem has a conversion efficiency problem. The raw input — human ambition, risk appetite, technical education — is there. But too little of it is making it through to the output: funded ventures, commercially viable products, globally scaling companies.

Thai universities produce research. Thai entrepreneurs have ideas. Thai people are genuinely willing to take personal risk. But the system that should convert all of that raw material into funded ventures, commercially viable IP, and globally ambitious companies is underdeveloped. Early-stage startup funding from 2022 to 2024 averaged US0.1 million in Bangkok, compared to a global average of US14.8 million. The pipeline exists; the plumbing does not.

The climate tech sector illustrates this starkly. As of 2024, stakeholder consultations found that only two climate tech startups had been founded in Thailand in the previous five years — despite the country having both the research talent and the urgent national need. University spin-offs, the typical engine of deep-tech commercialisation, remain poorly incentivised and institutionally undersupported.

There is also a mindset gap around market ambition. Thai entrepreneurs naturally think domestically first — which makes sense given a market of 72 million people. But a company designed only for Thailand faces a ceiling from the start. Singapore founders are forced by geography to think globally. Thai founders need to choose to.

 

Four Conversions Thailand Needs
In energy systems, conversion does not happen in one step. Sunlight becomes electricity, electricity becomes stored charge, stored charge becomes transmitted power. Each stage requires its own mechanism, its own efficiency, its own engineering. Building a startup ecosystem works the same way. There is no single fix. There are four conversions that need to happen — and right now, Thailand is losing energy at every stage.
1. Conversion of risk into disciplined ventures.
Raw risk-taking without structure produces activity, not companies. Thailand has founders willing to leap — but leaping without mentorship, capital, and institutional guardrails means most of that energy dissipates before it reaches scale.

2. Conversion of research into products.
Thai universities generate knowledge. Too much of it stays in papers, prototypes, and grant reports — never reaching the market. The bridge between laboratory and commercial product is weak, and without it, intellectual energy is wasted just as surely as sunlight hitting an unconnected solar panel.

3. Conversion of local ideas into regional or global companies.
A startup built only for Thailand is a solar panel designed to power a single room. The technology may be sound, but the architecture limits the output from the start. Thai founders need frameworks, networks, and market-entry support that help them think beyond the domestic ceiling.

4. Conversion of scattered ambition into an ecosystem.
Individual ambition without coordination produces isolated bright spots, not a self-reinforcing system. An ecosystem — like a well-designed energy grid — is valuable precisely because its components are connected. Capital flows to founders. Founders produce companies. Companies attract more talent. Talent generates more ideas. Right now, Thailand has the components. It is missing the connections.

 

The Opportunity
Thailand does not need to become Singapore or replicate Silicon Valley. It has something neither of those places has in quite the same form: a population with genuine entrepreneurial instinct, a willingness to operate under uncertainty, and a lived culture of starting things from scratch.
The question is whether that energy can be given better infrastructure to run on. In my field, we often say that the sun is not the constraint — the system is. Thailand's entrepreneurial sun is shining. The country now needs to build the infrastructure to convert that light into something the world can use.
The Thai startup ecosystem is not stuck because Thai people lack the will to build. It is stuck because the system around them has not yet been built to match that will. Fix the conversion infrastructure, and the energy is already there.
