Startup News 🚀💰:
- Lightship, a startup building electric RV’s, raised a $23M Series A led by Prelude Ventures. Existing and new investors include Obvious Ventures, Congruent Ventures, My Climate Journey, HyperGuap and Alumni Ventures.
- ForSight robotics, a startup building surgical robots for cataract surgery, raised a $55M Series A led by The Adani Group alongside existing investors Eclipse Ventures and Mithril Capital.
- Syrius, a Chinese warehouse-robotics startup, raised a $7M round led by Harvest Capital along with Bytedance.
- The United Arab Emirates launched an $820M fund to boost the domestic space economy, largely in an effort to help diversify its oil-dependent economy.

- Anduril is aiming to become the sixth ‘defense prime’ in the US, and bring a fresh wave of talent and hardware + software innovation into the defense industry. Great breakdown of Anduril’s business model and focus on software + AI to win the defense market and attract the best tech talent.
- The equipment multiplier effect on the chip shortage: a typical FPGA test tool requires approximately 80 FPGAs to build. However, that tester can then test about 320,000 FPGAs per year – a multiplier effect of ~4,000x. Optical wafer inspection tools require roughly 100 high performance computing (HPC) server chips to manufacture. Their multiplier effect can be ~30,000x and much higher.
