Company Background

Founded in 2015, Otsaw develops autonomous mobile robots from its base in Singapore. The company is led by founder and CEO Ming Ling, who is also a primary shareholder.

Other primary shareholders include private investors Derek Goh, Hui Koh, and Siong Goh.

Otsaw reported approximately $4 million in revenue for the 12 months ended October 31, 2024, placing the company at a relatively early stage in terms of reported revenue compared with larger technology companies entering the U.S. IPO market.

IPO Details

Otsaw initially filed for an IPO in June 2025. In its most recent filing in July 2025, the company planned to raise approximately $22 million by offering 4.4 million shares at a proposed price range of $4.50 to $5.50 per share.

The company had planned to list on the Nasdaq under the symbol OTSA.

Aegis Capital Corp. was expected to serve as the sole bookrunner for the transaction.

Otsaw withdrew its IPO plans on Tuesday, ending the proposed U.S. listing.

Market Context & Opportunities

Otsaw operates in the autonomous robotics market, where mobile robots can be developed for applications requiring automated movement and operations. Its focus on autonomous mobile robotics places the company within a technology segment that has attracted interest from businesses seeking greater automation.

A U.S. listing could have provided Otsaw with access to public-market investors and additional visibility for its robotics business. However, the company’s relatively small revenue base and proposed $22 million offering placed the transaction within the smaller end of the U.S. IPO market.

Risks & Challenges

The withdrawal leaves uncertainty around Otsaw’s future plans for accessing U.S. public markets. The company had been preparing for a Nasdaq listing since its initial filing in June 2025, but ultimately did not complete the proposed transaction.

Its reported $4 million in revenue also highlights the relatively small scale of the business at the time of its most recent disclosed financial period. For a robotics developer, continued development and commercialization can require significant resources, while the company’s ability to expand revenue remains an important factor in any future capital-markets strategy.

Closing Paragraph

Otsaw’s withdrawal of its proposed $22 million U.S. IPO marks the end of a listing effort that began more than a year earlier. The Singapore-based robotics developer had planned to bring its autonomous mobile robotics business to the Nasdaq under the ticker OTSA, but the transaction did not proceed. With approximately $4 million in revenue reported for the 12 months ended October 31, 2024, Otsaw remains a relatively small technology company, making its future financing and public-market plans important factors to watch.
