Simular bets on flat-fee AI agents over billing per token

AI startup Simular is experimenting with a flat-fee subscription that lets users run unlimited tasks on its cloud-based autonomous computer, Sai, co-founder and CEO Ang Li told Tech in Asia on the sidelines of the SuperAI conference in Singapore earlier this month.

Launched in March, Sai is an AI co-worker that operates its own cloud-based computer. It can click, type, and move between websites and apps to complete tasks for users.

Unlike computer-use agents such as Claude Cowork, which run on the user’s device, Sai runs on a dedicated remote desktop and can continue working after the user closes their device.

Li said Sai was still in private beta at the time of the interview. The CEO declined to disclose revenue or customer numbers, arguing that what’s more important at this stage is how much time the agent takes to complete all the tasks given.

“What’s the working hours of my agent for you?” he said, describing the company’s north star metric.

Sai’s website lists a US$20 monthly plan that lets people use the AI to automate tasks on a cloud-based Windows computer. This is discounted from the usual price of US$200, and it includes US$20 in usage credits. Meanwhile, the Pro tier with unlimited credits costs US$500 per month.

For Apple users, the US-based startup offers a US$200 monthly Mac plan that gives each user virtual access to a physical Mac Mini. Li said Apple’s restrictions on the number of virtual machines that can run on one device led Simular to use physical hardware.

The company raised US$21.5 million in December 2025. It has 20 employees, with around half of them based in Singapore. The company is actively hiring in the city-state, including for engineering and research roles.

Automating work without APIs

According to Li, some of Sai’s early users include an ecommerce business moving customer information from spreadsheets to websites, a car dealership validating vehicle identification numbers, and medical practices checking patients’ insurance coverage.

These workflows are still typically handled by staff copying data between systems, he added.

Sai is designed to continue working on its own in the cloud even after a user closes their laptop. Li claimed that, to his knowledge, Simular is the only computer-agent company giving every person a dedicated virtual desktop instead of running on a user’s existing computer.
