I invested in Small Robots Co (https://smallrobotco.com/) who were doing something similar. They had a good product, good brand, raised some funding, and were starting to get traction, with robots in trials on a number of farms, but at the end of the day they ran out of funding before they reached default-alive.

It's a tough space - convincing farmers to give it a go and running trials takes time and the UK isn't a very startup-friendly environment - investors are too often looking for a quick return.

This is such an important area - it's only going to become more critical to be able to grow more food whilst using less fertiliser and weed killer - so I wish you the very best of luck!
