Why A2D Ventures Is Bringing More Y Combinator Deals to Southeast Asian Investors

Over the past year, a pattern has started to emerge in some of the opportunities coming through A2D Ventures.

LineWise. Lumius. Traceforce.

All three are Y Combinator-backed companies. All are building in globally relevant technology categories. And they represent a direction we intend to explore further.

A2D will continue to source and back promising companies from Southeast Asia. The region remains core to our investment ecosystem and community.

But we also believe Southeast Asian angel investors should have access to opportunities beyond the deal flow that naturally circulates within the region.

That means broadening the opportunity set.

And one of the ecosystems we are paying increasingly close attention to is Y Combinator.

Why YC?

Being accepted into Y Combinator does not automatically make a company a good investment.

Every opportunity still needs to stand on its own fundamentals: the founders, technology, market, traction, valuation and potential path forward.

What YC does provide, however, is access to a concentrated ecosystem of founders building ambitious companies for global markets.

For A2D, that makes it an interesting hunting ground for potential outliers.

We are particularly interested in companies operating across several areas where we believe major new technology cycles are forming:

• AI Application Layer — products translating rapidly advancing AI capabilities into real-world business and consumer use cases.

• AI Infrastructure — security, data infrastructure, developer tooling, agent infrastructure and other systems supporting widespread AI adoption.

• HealthTech — medical devices, diagnostics, imaging and AI-enabled healthcare.

• Robotics & Physical AI — technologies bringing increasingly capable intelligence into the physical world.

• Chips, GPU & Compute Infrastructure — the hardware and infrastructure powering the expansion of AI.

These markets are highly technical, move quickly and can become global almost immediately.

That creates a different type of early-stage opportunity.

LineWise: An Early Example of the Potential

We have already seen what access to this type of deal flow can look like.

When A2D first brought LineWise to our investor community, the company was still at an early stage.

Since then, LineWise has:

grown revenue by approximately 20×,

increased its valuation by approximately 4×,

and secured contracts with two of the world's largest AI frontier companies.

None of this means that every YC-backed company will follow the same trajectory.

Early-stage investing remains inherently high risk, and past performance from one company is never an indication of what another will achieve.

But LineWise demonstrates why we believe having access to these companies early can matter.

The opportunity was not simply exposure to another startup.

It was exposure to a technical team operating inside one of the fastest-moving technology markets in the world, before much of that growth had become visible.

From LineWise to Lumius and Traceforce

LineWise was not an isolated opportunity.

We subsequently brought Lumius, a YC-backed HealthTech company developing a new approach to 3D ultrasound.

The company is entering a category where traditional high-end ultrasound systems can cost hundreds of thousands of dollars, while Lumius is developing a significantly more accessible device designed around modern imaging technology.

We then brought Traceforce, an AI security company building infrastructure for a world in which AI agents increasingly operate inside enterprise environments.

Its founding team combines deep technical experience across cybersecurity, AI infrastructure and leading academic institutions.

The sectors are different.

The common thread is not.

Technical founders. Large markets. Global ambition. And technologies positioned around major structural shifts.

Those are characteristics we want to continue looking for.

Why Founder Quality Matters So Much at the Early Stage

Traditional financial analysis becomes more difficult the earlier an investor enters a company.

At pre-seed and seed, there may not yet be years of revenue history, mature unit economics or a predictable operating model.

That makes the team especially important.

We pay close attention to founders with strong founder-market fit and evidence that they are capable of solving unusually difficult problems.

That can include:

PhDs working directly in their fields of expertise.

Engineers from leading global technology companies.

Founders from institutions such as MIT and other major technical universities.

Repeat entrepreneurs who have previously built or exited companies.

Operators with deep domain knowledge in the industries they are now trying to transform.

Credentials alone do not make an investment.

But when strong technical backgrounds are combined with speed, market insight, commercial traction and the ability to attract customers, they can become meaningful signals at the earliest stages of a company.

The Liquidity Question Matters Too

Angel investing is not only about identifying companies capable of creating value.

It is also about eventually being able to realise that value.

And one of the challenges in Southeast Asian venture investing has historically been the length of the exit cycle.

In 2025 YTD, the median age of a VC-backed Southeast Asian company at exit was approximately 6.8 years.

By comparison, U.S. venture-backed companies acquired in 2025 had a median time of approximately 4.6 years from initial funding to acquisition.

These statistics use different methodologies, so they should not be treated as a direct apples-to-apples comparison.

Nor does investing in a U.S. or YC-backed startup mean an exit will occur within a specific timeframe.

But the broader point matters.

Globally oriented technology companies can operate within deeper ecosystems of strategic buyers, later-stage investors, technology companies and acquisition activity.

For angel investors, that can potentially create more pathways to liquidity.

And time to liquidity is something we believe deserves consideration alongside potential returns.

Southeast Asia Is Still Core to A2D

Expanding our YC deal flow does not mean A2D is moving away from Southeast Asia.

Quite the opposite.

We continue to believe there are exceptional founders and companies being built across Thailand, Singapore, Indonesia, Vietnam and the wider region.

We will continue sourcing those opportunities and connecting them with our investor community.

What is changing is the breadth of what investors on A2D can access.

Traditionally, an angel investor's deal flow is heavily influenced by geography and network.

A Southeast Asian investor is naturally more likely to hear about companies being built in Southeast Asia.

A Silicon Valley investor is more likely to encounter companies emerging from Silicon Valley.

Technology increasingly operates without those boundaries.

We believe access should too.

Our goal is therefore to continue finding strong opportunities within Southeast Asia while also opening a window into global early-stage ecosystems that regional investors may otherwise struggle to access.

Broadening the Opportunity Set

Venture investing is driven by outliers.

A relatively small number of companies can create a disproportionate share of the value across a portfolio.

That means expanding where we search for those companies matters.

For A2D, Southeast Asia remains core.

YC simply expands the frontier.

LineWise gave us an early example of what that broader access can potentially produce.

Lumius and Traceforce followed.

And we intend to keep looking.

Because ultimately, the goal isn't to bring investors more companies.

It's to give them access to more places where exceptional companies can emerge.

The YC badge may get our attention.

The company still has to earn our conviction.
