In 2025, Southeast Asia’s tech startup ecosystem is entering a phase of measured maturity. It is no longer defined by scrappy experimentation or headline-chasing unicorn valuations. The region is now home to a generation of founders and investors focused on sustainable innovation, sharper business fundamentals and regional scalability.
According to Bain & Company’s 2024 Southeast Asia Tech Report, the region attracted over US$11 billion in tech investments last year, a modest rebound after the funding dip of 2022, but notably more targeted. Startups in sectors like AI, fintech and green technology accounted for the bulk of this capital, reflecting a broader shift in investor priorities.
Why Southeast Asia’s next unicorns are embedded fintechs hiding inside vertical SaaS
What’s driving this evolution? A combination of post-pandemic recalibration, geopolitical tailwinds and a maturing digital consumer base. Today’s Southeast Asian startups are operating in a more discerning environment, one where operational efficiency and real-world problem solving outweigh vanity metrics.
In this new landscape, five trends are shaping the next generation of regional champions. From AI-powered vertical SaaS to cross-border expansions led by emerging markets, these shifts offer a glimpse into how the region is rewriting the playbook on tech entrepreneurship.
Here are five trends defining this new era of tech entrepreneurship in the region.
AI-powered vertical SaaS is quietly taking over traditional sectors
While consumer-facing tech still dominates headlines, the real disruption in 2025 is happening behind the scenes. Across sectors like logistics, education, construction and fisheries, startups are deploying AI to solve hyper-specific business challenges, from automated inventory for smallholder farmers to predictive analytics for school dropouts and smart scheduling for field crews. In fact, vertical AI-powered SaaS startups across Southeast Asia have already attracted over US$2.2 billion in funding, signaling growing investor conviction in deep industry integration.
Investors are taking note. Unlike generic horizontal SaaS, these vertical solutions are deeply embedded and harder to replace. This makes customer retention stronger and recurring revenue more predictable- both key metrics in today’s funding landscape. With Southeast Asia’s SaaS market projected to grow from US$3.2 billion in 2024 to US$8.6 billion by 2029, the region offers fertile ground for vertical players solving sector-specific pain points at scale.
Climate tech and agri-tech are heating up for the right reasons
Once viewed as niche or grant-dependent, climate tech and agri-tech startups are finally attracting serious venture capital in Southeast Asia. This shift is driven by urgency. From floods in Jakarta to rice shortages in the Mekong Delta, climate change is no longer abstract. It’s affecting bottom lines and livelihoods.
In Malaysia, agritech startup BoomGrow is leveraging controlled environment farming to reduce pesticide use and improve crop yields. In Indonesia, solar microgrid companies are bringing clean energy to off-grid communities while maintaining unit economics that appeal to investors.
Climate‑tech deals now make up 9.5 percent of total venture funding in the region, up from 3.2 per cent in 2019. This is a clear sign that capital is flowing into ventures ready for the next phase of Climate 3.0, beyond demonstration to deployment. This shift mirrors the evolution of investor strategy: it’s become less about idealism and more about infrastructure. Climate tech investments in the region saw an annual growth rate of over 15 per cent between 2019 and 2023. More than 30 climate‑specific funds with majority allocations to the region have emerged since 2020, cumulatively raising north of US $830 million in committed capital.
Second-time founders and alumni startups are shaping the next wave
Southeast Asia is now benefiting from its first real generation of startup alumni. Employees from Grab, Shopee, Gojek and Tokopedia are branching out with ideas of their own and this time, they’re skipping the beginner’s mistakes.
Second-time founders tend to be faster, more capital efficient and have extensive networks. In Singapore, ex-Carousell staff have launched fintech tools for Gen Z freelancers. In Vietnam, GHTK alumni are pioneering last-mile robotics startups.
The presence of mature founders is also leading to healthier company cultures. Hiring is more deliberate, product-market fit is validated earlier and burn rates are lower.
VCs are prioritising profitability over heady growth
Gone are the days of growth-at-all-costs. Venture capital firms across Southeast Asia are placing greater emphasis on unit economics, lean operations and paths to profitability. It’s not that growth is no longer attractive, it just needs to make sense.
According to a DealStreetAsia report, early-stage check sizes have stayed consistent, but follow-on funding is now more closely tied to sustainable metrics rather than vanity KPIs.
This change is also affecting pitch decks. Slides about team pedigree and total addressable market are giving way to CAC-LTV ratios, churn rates and cash flow projections. It’s a back-to-basics mindset that’s been long overdue.
Indonesian and Vietnamese startups are leading regional expansion
Cross-border growth used to be synonymous with Singaporean startups scaling into Malaysia or Indonesia. But in 2025, the narrative is shifting. Founders from Jakarta, Ho Chi Minh City and even Surabaya are now actively expanding into neighbouring markets, often skipping Singapore altogether.
Vietnamese fintech firms are gaining traction in Thailand. Indonesian healthtech platforms are onboarding clinics in the Philippines. These companies are backed by increasingly confident local investors who are betting on regional dominance.
This reversal is powered by three things- home market saturation, regional digital payment interoperability and a new class of bilingual founders who understand diverse markets. These trends indicate that the ASEAN startup ecosystem is becoming less centralised. That’s a good thing.
What’s next for the region?
These five emerging trends show a region in transition – not just surviving but recalibrating. Southeast Asia’s startups are maturing, not only in their products and strategies, but also in how they think about growth, capital and scale.
With deeper tech integration, stronger founder pedigrees, a more discerning VC environment and an increasingly regional playbook, the conditions are ripe for the emergence of the next wave of unicorns and more importantly, sustainable businesses that reflect Southeast Asia’s diversity and ambition.
