Before the internet, there was the Zhejiang merchant. Wahaha (1987) proved a private founder could out-build the state firms from a school shop on Qingtai Street; Supor turned family pressure-cookers into a global brand; and one county — Tonglu — sent its cousins and classmates to Shanghai with parcels on their backs, creating the STO-Yunda-YTO-ZTO courier dynasty that still moves most of China's packages. This cluster is the culture layer: everything else in Hangzhou, Alibaba included, is Zhejiang merchant DNA with better tooling.

Hangzhou's enterprise-software bench predates its consumer fame. Hundsun (1995) wired China's brokers and funds, and after Ant invested in 2014 it became the connective tissue between old finance and new. H3C (2003), shuffled through Huawei, 3Com, HP and Unigroup ownerships, settled in Binjiang as a networking and server heavyweight. The Alibaba-alumni generation added Tuya (2014), whose cloud quietly animates no-name smart devices in 200+ countries — picks and shovels, Hangzhou style.

In 2001 two surveillance companies opened three kilometres apart on the south bank: Hikvision, spun from a state research institute, and Dahua, founded by engineer Fu Liquan. They grew into the global #1 and #2 of video surveillance, pulled an optics-and-vision supply chain around them, and calved further firms — Uniview out of H3C's security arm, Leapmotor out of Dahua's co-founder. Sanctions turned both flagships into geopolitical lightning rods; the cluster kept compounding anyway.

Alibaba is less a company on this map than a climate. Taobao and Tmall made Hangzhou the capital of Chinese e-commerce; Cainiao (2013) built the data layer that welds Tonglu-founded couriers into one network; NetEase's Binjiang campus (2006) gave the city a second internet giant's payroll. The shadow side is real too: Mogu, the fashion-commerce unicorn that listed on the NYSE and lost over 95%, and BEST, which sold its express arm after a brutal price war — platforms give, platforms take.

Hangzhou's manufacturing cluster runs on second acts. Supcon (1993) came out of a Zhejiang University lab to break the foreign grip on industrial control systems. Li Shufu pivoted from refrigerator parts to cars (1997) and bought Volvo (2010), running the Geely empire — Zeekr, Polestar stakes, Lotus — from Binjiang. Leapmotor (2015), founded by Dahua's co-founder at 48, became China's best-selling EV startup by 2025 with a Stellantis deal carrying it into Europe.

The robot wave is Hangzhou's newest export. Unitree (2016) started in a 50 m² Binjiang office with a mission to make legged robots absurdly cheap — its $16,000 humanoids danced on the Spring Festival Gala before a ~500% IPO pop in 2026. DEEP Robotics (2017), from a ZJU legged-robotics lab, sends industrial quadrupeds into power stations and tunnels. BrainCo (2015) brought Harvard brain-computer research home to Future Sci-Tech City. Three of the Six Little Dragons live in this cluster alone.

The headline cluster of the Dragon Years. DeepSeek (2023), spun from quant fund High-Flyer, shook global markets with R1 in January 2025 and made 'Hangzhou' an answer to 'where is China's AI?'. Game Science, seven ex-Tencent developers in a subsidised Xihu arts village, shipped Black Myth: Wukong — 10 million copies in three days. Rokid pushes consumer AR from Yuhang, and Manycore's spatial-intelligence engine (the sixth dragon, first to file for IPO) renders the physical world for designers and robots alike.

One company is the cluster — but what a company. Alipay began in 2004 as an escrow trick to make strangers trust Taobao; it grew into Ant Group, a billion-plus users, MYbank, and the wealth-tech stack of Chinese daily life. Its $37 billion IPO — set to be history's largest — was halted 48 hours before trading in November 2020, triggering the platform-economy reset. Restructured and recapitalised, Ant still runs global fintech from Z Space by the Xixi wetlands, with Hundsun's market plumbing next door in Binjiang.
