#74 Hong Kong vs Shenzhen vs Singapore for Hardware Founders

\# Hong Kong vs Shenzhen vs Singapore for Hardware Founders## Guest IntroductionI'm joined by Charudatta Datar, CEO & Co-founder at Astra Optics, a CUHK spin-off that builds ultra-fast nanoscale 3D printers. An MIT-trained mechanical engineer, he left Boston to turn a professor's Science-published breakthrough into a company across Hong Kong, Shenzhen and Hefei.## Episode SummaryFor years, nanoscale 3D printing sold almost only to university labs, because it was too slow for any factory. Now AI data centers are moving from copper to light, and that move needs hair-width lenses that a fast nanoscale printer can prototype in hours. This episode shows how a professor's lab invention becomes an industrial company, and why the money and the factories for that journey are in mainland China.## Key Points- 🔦 Why AI data centers suddenly need lenses as wide as a human hair- ⚡ The one bet that separates this startup from competitors who perfect materials- 💰 The seed offer from Singapore that was 5-6x lower than the offer from mainland China- 🏛️ How Chinese city governments compete to win deep-tech startups- 🎓 Why mainland investors back the professor, not just the startup- 🏭 Hong Kong vs Shenzhen for hardware: where to put the HQ and where to build- 📦 The sourcing rule from Yiwu: find demand first, supply in China follows## Important Links- You can reach Charudatta Datar at https://www.linkedin.com/in/charudatta-datar-667808a/- Vishesh, your host at https://vishesh.space- Checkout Astra Optics at https://astra-optics.com- Hands hurt while you use the keyboard or mouse? https://tryneo.dev## Chapters0:00 - Introduction1:05 - From MIT to a professor's nanofabrication lab in Hong Kong4:54 - Why professors make a PhD student the CEO of their spin-off7:23 - Why the headquarters moved from Hong Kong to Hefei8:49 - RAISe+ and Hong Kong's professor-led ecosystem10:01 - How two-photon lithography prints a 3D pixel13:49 - The bet on speed over materials15:19 - Co-packaged optics: why AI data centers are moving from copper to light19:49 - Why prototyping, not mass production, is the first market21:30 - Selling to universities first, then to industry22:25 - Funding: the hardest problem in deep tech23:49 - Government grants in Hong Kong, Hefei and the EU25:30 - Why mainland VCs invest in the professor27:50 - Hong Kong vs Shenzhen vs mainland China for hardware30:19 - The Singapore offer that was 5-6x lower32:19 - How China's local governments compete for startups33:49 - An Indian CEO in China: Shenzhen, the Greater Bay Area and high-speed rail36:42 - Language and culture as a foreign founder38:06 - The pre-Series A round and the pitch to Western investors39:51 - Why hardware moves faster in mainland China41:19 - The biggest unlock: narrowing to a few industry use cases43:48 - Marketing on WeChat vs LinkedIn47:08 - How to source and sell in ChinaTopic: Deep Tech Fundraising in China
