Voice AI startup Wiz.AI roars to US$3.9m profit in 2025

The last time you called your bank, chances are the “person” who picked up the phone was an AI agent.

As voice agents become more ubiquitous in customer service, the companies running them are making bank. One of them is Wiz.AI – the Singapore-based startup almost doubled its revenue year-on-year to US$23.5 million in 2025.

CEO and co-founder, Jianfeng Lu, credits the startup’s renewed focus for the jump. He took the helm at the beginning of last year, after Wiz.AI co-founder Jennifer Zhang stepped down from the post.

“In 2024, we lost focus, pursuing too many projects at once,” Lu tells Tech in Asia. So in 2025, the company chose projects that delivered “clear ROI in terms of strategy and economic value.” Instead of chasing “one-off deals,” Wiz.AI pursued “customers and projects that we knew will renew their contracts with us,” Lu says.

That direction allowed the firm to recover from a net loss of US$13.4 million in 2024 to a net profit of US$3.9 million in 2025. Its clients include some of the biggest names across Southeast Asia such as GCash in the Philippines as well as Telkomsel and Bank BRI in Indonesia.

Wiz.AI’s clients are mostly in the financial services, banking, telecom services and ecommerce, with the total now at “few hundreds,” Lu says.

SEA-first approach

Originally a chatbot provider, Wiz.AI pivoted to creating generative AI-powered voice agents in 2021.

Its enterprise clients typically use its services for a simple use case, such as voice agents that call customers to remind them of their credit card due dates. “Clients initially check if we can handle simple calls, before eventually expanding … to more complicated tasks,” Lu says.

He adds that last year, most of Wiz.AI’s customer base deployed more agents for other customer service scenarios like cross-selling other products and taking inbound calls.

Lu believes enterprises see the benefit of using AI voice agents as they can easily scale operations based on day-to-day demand. Currently, Wiz.AI clients either pay a subscription fee based on the number of voice agents deployed or based on the volume of calls taken by them, although the CEO didn’t share specific prices.

So far, Wiz.AI’s voice agents are fluent in 16 languages including Mandarin and unique hybrid variations like Taglish (Tagalog and English) and Singlish (Singaporean and English).

The startup trains its voice agents based on real conversations provided by either a third-party company or its own suite of clients. It is continuously training its language engine. Research and development costs made up a third of the firm’s total expenses in 2025 at US$15.3 million.

The company began expanding into South America this year, with plans to enter Brazil and Mexico. To set up sales and marketing teams in these countries, Wiz.AI aims to use the funds from a series B round announced in November 2025 that was led by SMBC Asia Rising Fund, the venture capital arm of Sumitomo Mitsui Banking Corporation of Japan.
