Bost Boer completed a Series B financing of over 1 billion yuan, achieving full coverage of three-axis products in the intelligent chassis | Exclusive from 36Kr

36Kr has exclusively learned that Bost, an intelligent chassis enterprise, recently completed its Series B+ financing round. The round was led by the Zhejiang New Energy Vehicle Industry Fund, with joint investments from Shunchuang Industrial Investment, Hangzhou Capital Direct Investment Fund, and others. The company raised over 700 million yuan in the Series B+ round, and the total financing in the Series B rounds has exceeded 1 billion yuan. The funds from this round will be used for the large - scale growth of existing products and the development of cutting - edge products.

Bost was founded in 2021. Its shareholders include not only the automaker NIO but also leading enterprises in the automotive chassis supply chain such as Henglong and Baolong. In 2025, Wu Ziping and Yu Wei, who had previously served as senior executives at chassis giant ZF, joined Bost successively and took up the positions of senior vice - presidents.

Currently, Bost's product portfolio covers the entire field of intelligent chassis, including braking, suspension, steering, and domain controllers. Liu Xiaohui, the founder and president of Bost, told 36Kr that the company's currently mass - delivered products mainly fall into three categories: the ESC vehicle stability control system, the One - Box integrated brake - by - wire system, and the intelligent suspension air supply system.

"In 2025, the company's revenue doubled, and its customers included Geely, GAC, FAW - Volkswagen Anhui, FAW - Volkswagen, SAIC - Volkswagen, BYD, Chery, Dongfeng, Dongfeng Nissan, BAIC, Changan, SAIC - GM - Wuling, and many overseas customers," Liu Xiaohui said. In 2026, the company successfully entered the supply system of joint - venture brands and became a supplier to the Volkswagen Group. The relevant products are expected to enter mass production in the fourth quarter of 2026.

With the support of the new round of financing, Bost will continue to increase its investment in the R & D and production of the EMB (Electro - Mechanical Braking) system.

In 2026, as relevant regulations were gradually relaxed, many new - force brands officially announced that they would install the EMB braking system in their mass - produced models. The industry generally regards this year as the first year of EMB commercialization.

Liu Xiaohui told 36Kr that the One - Box product, which is currently the mainstream in the brake - by - wire market, became a hot term in the industry as early as 2015. However, it took a decade for the One - Box to reach its current market share. "I believe that there are no short - term products in the braking industry, and large - scale application requires a relatively long cycle," he said.

Currently, the industry's understanding of the value of EMB is still in its early stage. "The market's understanding of EMB products is not deep enough. The understanding of EMB value is more about the better coupling and linkage between braking and other systems," Liu Xiaohui said.

The large - scale application of EMB will inevitably go through multiple stages, including the maturity of the supply chain, the collaboration of automakers, and the verification of user value. Bost has conducted pre - research on EMB products for many years and will launch highly competitive products at the right market inflection point.

In Liu Xiaohui's view, although the technical threshold of the braking system is relatively high, there are still many participants in the industry. "In a highly competitive environment, the profitability of a single braking product will continue to be under pressure."

Therefore, Bost has adopted a compound strategy of diversified layout and in - depth customization.

Among intelligent chassis start - ups, Bost is one of the few enterprises that have achieved stable mass production and delivery in the three major fields of braking, suspension, and steering. This complete technical ability and product portfolio covering the XYZ axes of the chassis provide a foundation for the company to expand system - level solutions in the future.

Liu Xiaohui said that currently, automakers are generally facing cost - reduction pressure. Bost is trying to achieve system - level cost reduction through R & D. "We have products in braking, steering, and suspension. Can these three systems be integrated? Are there any parts, especially electronic components, that can be reused? Can software development be platformized? I believe that only enterprises with a full - link product portfolio of the automotive chassis have the ability to achieve system - level integration and cost reduction."

The intelligentization of the chassis has become an irreversible trend in the automotive industry. Multiple factors, including intelligent interconnection to support high - level autonomous driving, integrated solutions required by automakers for cost - reduction and efficiency - improvement, and users' demand for better driving experience, are jointly driving this systematic change.

According to incomplete statistics, there are currently about 40 start - up enterprises in the domestic intelligent chassis field. Compared with traditional supply - chain enterprises, these start - ups are more focused on the R & D and commercialization of intelligent chassis technologies. The company that can achieve technological breakthroughs and commercial success first may reshape the future landscape of this niche field.

"For start - up companies, continuous operation itself is a victory," Liu Xiaohui said. "The core lies in establishing a business closed - loop and achieving continuous growth in revenue and profit." He pointed out that the key to breaking the situation lies in two major strategies: one is to break into the high - end product market and avoid price competition in the low - end market; the other is to accelerate the expansion into overseas markets to obtain higher profit margins.

Bost is moving forward according to such a strategy. The company aims to achieve a revenue of 1 billion yuan in 2027 and achieve full profitability. Overseas, Bost is in talks with some mainstream European automotive brands and is expected to make new breakthroughs in the near future.

Every breakthrough of Bost not only concerns the achievement of its own business closed - loop but may also become an important force in defining the future landscape of the intelligent chassis industry in China and even the world.
