Just received a 500 million yuan investment, this "Six Little Dragons of Hangzhou" is preparing for an IPO.

This time, it's the turn of Cloud Deep.

On December 23, the IPO counseling publicity system of the China Securities Regulatory Commission (CSRC) showed that Hangzhou Cloud Deep Technology Co., Ltd. (hereinafter referred to as "Cloud Deep") submitted an IPO counseling filing to the Zhejiang Securities Regulatory Bureau. The counseling brokerage is CITIC Construction Investment.

It's worth noting that half a month before submitting the counseling filing, Cloud Deep just completed a Series C financing of over 500 million yuan, with more than 14 institutions participating in the "group purchase". In the second half of this year, Cloud Deep has completed two rounds of financing within half a year, with a cumulative financing of over 1 billion yuan.

There is a trend of going public after successful financing, and Cloud Deep's journey to IPO is not without signs.

During the same period when institutions were rushing to invest, in November, Cloud Deep carried out a shareholding system reform, changing its name from Hangzhou Cloud Deep Technology Co., Ltd. to Hangzhou Cloud Deep Technology Co., Ltd. The enterprise type changed from "other limited liability company" to "other joint-stock company (non-listed)".

Although the company said externally at that time that "this shareholding system reform is mainly due to the company's development needs and to complete the corresponding preliminary preparations", considering that there was only a two - month interval between the shareholding system reform and the start of IPO counseling for both Unitree Technology and Leju Robot, this move has clearly revealed Cloud Deep's intention to go public.

Currently, there is only a one - month interval between Cloud Deep's shareholding system reform and the counseling filing, which undoubtedly speeds up its IPO process.

Looking at Cloud Deep's latest move, the actions of the "Six Little Dragons of Hangzhou" to sprint for listing have become a beautiful scenery in the venture capital circle.

Unitree, also a leading player in embodied intelligence, only took 132 days from starting the counseling filing on July 18, 2025, to completing the acceptance on November 15, setting a record for the fastest IPO counseling speed in the A - share market. As the first IPO enterprise among the "Six Little Dragons of Hangzhou", Qunhe Technology has officially submitted a listing application to the Hong Kong Stock Exchange, aiming to become the "world's first stock in spatial intelligence".

According to foreign media reports in August, Qiangnao Technology is also negotiating a pre - IPO financing of about 100 million US dollars at a valuation of over 1.3 billion US dollars, which may pave the way for its subsequent IPO in Hong Kong or the Chinese mainland.

That is to say, so far, half of the "Six Little Dragons of Hangzhou", this "mysterious oriental force", have embarked on the journey to go public.

Cloud Deep, which is speeding up its IPO this time, was founded in November 2017 by Zhu Qiuguo, an associate professor and doctoral supervisor at the School of Control Science and Engineering of Zhejiang University, and Dr. Li Chao, who also comes from a Zhejiang University laboratory.

According to the counseling filing, Zhu Qiuguo is the controlling shareholder and actual controller of the company, and he and his persons acting in concert hold a total of 32.60% of the shares.

Currently, the "Jueying" series and Lynx series robots independently developed by Cloud Deep have been applied in various environments such as power inspection, security patrol, survey and exploration, public rescue, pipe gallery tunnels, metal smelting, construction surveying and mapping, education and scientific research, and have become the core product pillars of Cloud Deep Technology.

In December 2024, the Jueying series robotic dogs of Cloud Deep "took up their posts" in the power transmission cable tunnels of Singapore Energy Group, becoming the first domestic industry - level quadruped robot to be applied in an overseas power system.

The quadruped robot industry report released by IDC shows that in 2024, the global quadruped robot market scale exceeded 180 million US dollars, with a shipment volume of about 20,000 units. The application demand has expanded in fields such as power, petroleum, and public safety. Cloud Deep ranks first in the industry in many B - end application fields.

According to a set of data disclosed by Zhu Qiuguo to "China Entrepreneur", Cloud Deep's revenue in 2024 increased by more than 100% compared with 2023. He said that in 2025, Cloud Deep's robot shipment volume will reach the level of 10,000 units. Currently, it has entered markets in the Asia - Pacific, the Middle East, Europe, and the United States. He revealed that the Cloud Deep team has nearly 400 people, mainly concentrated in product research, production and manufacturing, and market sales.

In addition to pioneering the industry in the field of Chinese quadruped robots many times, in the past two years, Cloud Deep has also extended its reach to humanoid robots and wheel - legged robots.

In 2024, it launched its first humanoid robot, Dr.01, which uses an enhanced learning algorithm, has a walking speed of over 1.6 meters per second, and supports walking on a 25° slope, firing the first shot for Cloud Deep to enter the humanoid robot track.

This year, Cloud Deep also released the world's first industry - level medium - sized wheel - legged robot "Lynx M20" designed for complex terrains, covering high - risk scenarios such as power inspection and fire emergency response, further expanding the industry application boundaries.

It's not hard to see that Cloud Deep is moving forward towards the "1 + X+N" strategy developed by Zhu Qiuguo.

That is, with the embodied intelligence system as the core (1), relying on more than 100 implementation case data in the power industry and multi - modal small models to improve scene recognition and risk prediction capabilities; exploring X innovative robot forms (X) to expand diversified product lines such as humanoid and wheel - legged robots; deeply cultivating N industry scenarios (N) to accelerate market penetration in Europe, America, and Southeast Asia and build a global service network.

Now, Zhu Qiuguo is going to lead his "robot kingdom" into a new chapter.
