Hillhouse-backed Ascentium buys fellow business services firm Dezan Shira, as the platform tries to ride China’s surge in outbound investment

“We did not have a meaningful capability to service multinational corporations that wanted to go into mainland China,” Lennard Yong, Ascentium’s co-founder and CEO, tells Fortune. The acquisition adds new offices in mainland Chinese cities like Guangzhou and Tianjin, and pairs Ascentium’s outbound expertise with Dezan Shira’s inbound knowledge.

Chinese outward investment reached $174 billion last year, a 7% increase. A 2025 report from McKinsey notes that China is now a net investor overseas, partly due to decreased inward flows from the U.S. and Europe, but also because Chinese firms are racing to diversify supply chains and chase consumers in emerging markets. “Ascentium has the capability to bring Chinese companies out globally,” Yong explains.

China’s exports to ASEAN jumped 13.4% last year; exports to Vietnam alone surged more than 22%. Exports to the U.S., by contrast, plunged 20%, due to U.S. President Donald Trump’s tariff regime.

Alberto Vettoretti, a managing partner at Dezan Shira who joined the firm in the late 1990s, has noticed the shift in where his customers are coming from. Five years ago, most of his customers were American or European. “Now, one-third of our customers in Vietnam are Chinese,” he says. “The switch in nationalities has been quite large.” 

Vietnam in particular is benefiting from greater inward investment from China and other economies. The Southeast Asian country grew by 8.0% last year, with manufacturing expanding by almost 10%; the country’s stock market is set for a FTSE upgrade to emerging market status later this year. The Dezan Shira deal will double Ascentium’s capacity in the country.

“When you talk to people in Vietnam, they’re all very hungry,” Vettoretti says. “You see a lot of young entrepreneurs coming up through the ranks.”

The roll-up logic

Yong, a chartered accountant who previously spent five years as group CEO of Tricor, founded Ascentium in 2024 with his cofounder Wendy Wang. The platform now provides finance and accounting, payroll, HR, and cross-border services (among others) across 46 cities in 27 markets, in a footprint stitched together from several acquisitions across the region, including InCorp Global and Links International. (Ascentium is a clear example of a roll-up strategy, popular among private equity, where a company will acquire other firms to rapidly build capability and scale.)

Dezan Shira & Associates, founded in Hong Kong in 1992, spans 27 offices across the region. “We coveted the business they built with sweat and tears over three decades, and they’ve mastered the art of knowing how to set up businesses onshore in China.”

Yong notes that, eventually, the Dezan Shira brand will be folded into Ascentium, though he says the migration will be “controlled.” 

“We are not in the fast-moving consumer goods space,” Yong says. “It makes more sense for our clients to have a singular brand.”

Broadly, Yong hopes that Ascentium, as an Asia-focused company, will be well placed to capture Asian growth. “The world has evolved from a unipolar world to a multipolar world,” he says. “There are companies in Saudi Arabia, in the UAE, in Singapore, in Hong Kong, in Shanghai that are no longer reliant on North American and European trade flows.”

“We choose to be anchored in Asia because we want our CEOs to be very close to the Fortune 500 firms of tomorrow,” Yong adds.
