What is the Flapping Airplanes valuation story?
The San Francisco enterprise saw its financial worth quadruple since January, when it secured a $180M seed round. The latest funding event, reported by Bloomberg on Wednesday, was led by Index Ventures and Lux Capital. Other participants included Sequoia Capital, Alphabet’s GV, and Kleiner Perkins.
Index Ventures previously raised $2B in August to support more AI firms. The startup is part of a trend of neolabs focusing on research before shipping items to buyers, joining peers like Yann LeCun’s AMI Labs and Mirendil.
How does the AI research startup plan to use the funds?
Co-founder Asher Spector told Bloomberg that the team is working on methods to train models using less data and computing power while extracting more efficiency from hardware. The business has been writing its own version of the software that operates Nvidia graphics chips, according to co-founder Aidan Smith. Nvidia took part as an investor.
Spector stated that the basic thesis is that demand will outpace chip and data supply. The company eventually plans to sell its technology to make AI cheaper for other businesses.
Why it matters
The investment arrives as AI companies spend heavily on data centres and hardware. By targeting chip efficiency, Flapping Airplanes aims to ease supply constraints for the broader industry. The venture draws its name from the ornithopter, representing a blend of natural and artificial intelligence strengths.
