AI Visual Inspection Startup Chixiao Technology Raises Tens of Millions of RMB in Series A Round | Led by Oasis Capital

Chixiao Technology, a company specializing in AI-powered visual inspection technology, recently announced the completion of a Series A round of financing worth tens of millions of RMB. The round was exclusively led by Oasis Capital, with Evolution Capital serving as the exclusive financial advisor. Dun Wang, founder of Chixiao Technology, stated that the funds will be used for product R&D, production scaling, sales, and talent acquisition.

Dun Wang, Founder and CEO of Chixiao Technology, said: "We firmly believe that only great products earn customer recognition. We've stayed focused on inspection in the new energy sector, especially the lithium battery supply chain, and we're fortunate to have caught the explosive growth of the new energy market in recent years. We chose to enter from upstream materials inspection, and have now built significant leading advantages and differentiation in niche markets like copper and aluminum foil and battery separators. We're deeply grateful for Oasis Capital's confidence in us — their team has offered me many fresh perspectives and critical support throughout our partnership. Going forward, we'll continue to stay focused and diligently refine our products and technology, increase investment in R&D and market expansion, seize the opportunities this era has given us, and drive Chixiao's continued rapid growth."

A spokesperson for Oasis Capital said: "The rapid development of downstream new energy applications in recent years has generated massive demand for inspection during production. As quality requirements for lithium batteries and upstream materials become increasingly stringent and production efficiency improves, customers are demanding new levels of performance in inspection speed, precision, and defect detection rates — making high-performance inspection equipment a necessity. The Chixiao team has spent years developing AI visual inspection technology and has established a significant industry position in upstream lithium battery materials inspection, while extending its advantages into the battery production process itself. We believe that with its deep accumulation in optics, algorithms, and scenario-specific data, combined with rapid product iteration capabilities, Chixiao can continue to empower more industry application scenarios, boost efficiency across the supply chain, and drive forward the industry's digital transformation."

Chixiao Technology is an innovative technology company focused on AI-powered visual inspection. It currently provides intelligent inspection equipment and product inspection solutions primarily for the new energy industry. Its main products are integrated surface defect inspection machines capable of detecting key lithium battery materials and components throughout the upstream and downstream supply chain, including separators, aluminum-plastic films, copper foil, aluminum foil, and electrode sheets.

The growth of the new energy industry has directly driven the lithium battery supply chain market, particularly in related inspection fields. According to industry data, the global market for defect inspection of lithium batteries and major materials such as copper/aluminum foil, separators, and aluminum-plastic films exceeded 7 billion RMB in 2022, and is expected to surpass 30 billion RMB by 2025.

At the same time, the characteristics of the lithium battery inspection market have become increasingly pronounced. First, automation, intelligence, and integration are advancing rapidly — manual inspection is no longer acceptable. Second, due to the special nature of the battery industry, quality control requirements are extremely strict, and the precision demands for material inspection continue to rise.

Dun Wang noted that while many companies currently offer AI visual inspection solutions, Chixiao Technology's deep focus on the new energy sector gives it significant advantages in detection accuracy, speed, and precision, enabling it to deliver superior quality inspection solutions to customers. Based on Chixiao's product performance metrics, its inspection speed, defect detection rate, and coverage of defect types all exceed industry averages.

Chixiao's performance advantages stem from three areas: optical component R&D capability, powerful algorithms, and extensive data foundations. On the data front, the team has accumulated substantial raw data through years of serving customers, and has expanded data volume and defect diversity through techniques like small-sample training and transfer learning.

Dun Wang explained: "Industrial data, especially defect data, is extremely difficult to obtain. It can only be accumulated through continuous effort — there are no shortcuts. Chixiao Technology has a leading advantage in this regard."

On the algorithm side, Chixiao employs multiple algorithm types in combination, and has performed extensive low-level parallel optimization, significantly improving processing speed. This enables rapid inspection of captured images while maintaining high precision. Regarding optical components, the company has independently written all its underlying code rather than relying on existing algorithm libraries.

Additionally, Chixiao has developed core components for its light sources and optical control systems in-house. By optimizing exposure timing, light source types, and capture modes, it can identify multiple defect types using a single capture mode, further improving inspection accuracy.

Chixiao offers dozens of product models across two major categories, meeting visual inspection needs across multiple industries, while continuing to focus its efforts on the new energy sector. Dun Wang stated: "Chixiao Technology's product performance and service quality have achieved significant advantages at this stage. Our project acceptance rate and order collection rate are nearly 100% — this market-level recognition is the best demonstration of Chixiao's capabilities."

On the team side, Founder and CEO Dun Wang graduated from the Chu Kochen Honors College at Zhejiang University, majoring in optoelectronic information engineering, and was a visiting scholar at Lawrence Berkeley National Laboratory in the United States. He has over 10 years of experience in AI and industrial inspection. Chixiao currently employs more than 40 people, primarily from top domestic and international universities and major industrial inspection or AI vision companies, serving over 100 customers. High per-capita productivity is another of Chixiao's strengths, and Dun Wang indicated that the company will leverage this to consolidate its industry position while making orderly team expansion.

Vitality

What do you think vitality is?

Life is nature's miracle in fighting against entropy. A company is also a life — an organizational life. Its natural direction is dissipation. Only through the careful design of the organization by entrepreneurs and their teams can entropy be resisted and value created. So corporate culture is the DNA of this life, determining what it can grow into.
