The creative destruction lab looks really cool, and I may ask for an introduction, but, I worry that I'm am not really trying to build a business here. I don't see a product or customers in growing forests robotically. It's just a forest. And the robots are to handle the scale, they are doing nothing a low skilled worker couldn't do.
I don't see any real business opportunity outside of selling carbon credits, but there are vastly more profitable ways to use land.
But it's a reliable and feasible solution to climate change nonetheless, and something I could theoretically do with funding. So, hence Kickstarter, a place where businesses don't need to be businesses! :)
Oh, I built a rover named Henry, but I can't quite say that he is a forest planting prototype.
In a similar position as yourself, I'm in deep tech and can share similar frustrations where funding is scarce and commercialization seems far away. Having attempted to fundraise, I can say that we've been blessed to be forced to bootstrap at this stage and are slowly identifying our commercial path. Happy to help you find a market.
The good news is that you are in a hot investment area and I can probably point you in the right direction with the right investors. Firstly, how far along are you? Do you have a prototype and have you spoken to potential customers?
One program that might be suitable for you is Creative Destruction Lab, who specialize in deep tech such as robotics (https://www.creativedestructionlab.com/program/). They don't take any equity and you'd have opportunities to be mentored and invested. I'd be happy to provide an introduction.
