Thanks for sharing this.
Regarding funding - I think this is a very crowded space and it is hard to see, how data station will get 10x better than other toolings. E.g. on the self-service side there are solutions like Alteryx, that are progressing quite quickly. On the dev oriented side e.g. for automated productive integrations you have various toolings available e.g. in the could platforms. Yes, they all cost money, but they deliver also value.
There will be a niche certainly for this tool somehow, but I think this path needs to be approached together with customers. So if you find someone who is willing to pay $$$ for a certain addition to the tool, you'll have some light into the direction this could head to be self-sustaining.
