CHUA KEE LOCK

Chua did not start in finance. He trained as an engineer at the University of Wisconsin-Madison and Stanford, focused on robotics.

Then he built and sold his own business. Before Vertex he was president of Biosensors International, a medical device maker, and a managing director at Walden International, a venture firm.

In 2008 Temasek asked him to rebuild its in-house fund called Vertex. His job was to fix it.

He did. He turned a single Temasek-funded pool into a global network of funds covering Southeast Asia and India, China, the US, and Israel.

In 2014 he restructured it into a partnership so partners had real skin in the game.

Vertex is not one fund. It is a family of regional funds, each with its own local team.

That was Chua's design. Vertex Ventures Southeast Asia and India made the firm's most famous bet, Grab.

Vertex Ventures China, Vertex Ventures US, and Vertex Ventures Israel each hunt in their own backyard. There is also Vertex Growth, a later-stage fund Chua chairs.

Portfolio names include Nium, a cross-border payments firm, PatSnap, and HappyFresh. Before all this he ran Biosensors International, which made heart stents.

Chua is patient to a fault. His own line is that Vertex is a disciplined investor, not a prolific one.

It does not spray money at every deal. It picks a few founders and works with them for years.

He cares more about why a founder is building something than what they are building. His view is that you can teach someone financial discipline, but you cannot teach attitude.

The regional fund model is the other big idea. Local teams know local markets better than a head office in Singapore ever could.

Grab. Vertex Ventures Southeast Asia was one of the earliest institutional backers of Grab, when it was still a scrappy taxi-hailing app.

Grab grew into Southeast Asia's biggest ride-hailing and delivery company. In 2021 it went public in the US through a SPAC deal that valued it at roughly $40 billion, the largest such deal at the time.

For a fund that started with $200 million, backing a company that big early is the win that defines the whole run.

Here is the honest asterisk on the Grab story. Grab went public at around $40 billion in 2021, then its shares fell hard, wiping out much of that paper value within a year.

Vertex made real money on Grab, but the SPAC-era hype showed how brutally public markets can punish growth-at-all-costs companies. The quieter critique of Vertex is that, for all its size, it has not produced a second Grab.

One giant win carries a lot of the story. Chua's own framing helps here.

He says not every deal works, and in venture that is the point.

Chua's rules are old-fashioned for a tech investor. First, back the person, not just the idea.

He wants to know why a founder is doing this, because attitude survives when the first plan fails. Second, stay disciplined.

Vertex does not chase every hot deal. Third, go local.

He built Vertex as a network of regional funds because a team in Jakarta or Bangalore reads its market better than an office in Singapore. Fourth, play the long game.

He sees Southeast Asian tech following the same path China and the US already walked. Patience, in his view, is the whole edge.

Chua keeps his private life private. He is Singaporean and built his early career across the US and Asia before settling back home to run Vertex.

What is public is his obsession with the work. Holding four roles at one firm does not leave much room for anything else.

He spends a lot of his time mentoring founders across the region, which is about as personal as his public story gets.

Chua studied engineering at the University of Wisconsin-Madison, then went to Stanford, where he focused on robotics. The engineering training shows in how he thinks.

He treats company-building like a system to be understood and fixed, not a bet to be placed and forgotten.
