BrainChip and Tata Elxsi Partner to Provide Intelligent, Ultralow-Power Solutions, page-16

This is pretty big in my opinion as the Tata group
are very big and involved in many large industrial projects. For example use of edge devices to improve the operation of remote oil and gas facilities is an area that I know Tata are looking to use edge devices.
There are many many facilities around the world that would benefit from such devices, which is only one of the many relevant industries for this technology.
I would not be trying to estimate the value of this company pre commercialisation, instead start thinking about just how big it will be post commercialisation, which justifies the current market cap in my opinion.
