So you suspect you may have oil hiding deep in your property, and while you know your land REALLY well, you're not totally sure how to go about validating that its there; or even if you could validate it, how to proceed best.
You hear there is a very friendly and experienced outfit called YC that will help you (a) quickly figure out if there's oil, and (b) if there might be oil, set you up for success with the bigger money that you'll need to extract the oil. This YC firm is basically geared towards helping someone like you figure this out quickly. And actually, YC will give you $ to explore this very thing. In exchange, they will own part of your land (a small fraction).
If it turns out there isn't oil after all - not the end of the world. You'll go back to farming, and at least you won't be wondering if you should have explored the oil thing more. YC won't care much about you anymore since they are in the business of owning a small % of the land that strikes BIG oil. But they also won't be a nuisance.
If it turns out there IS oil under there, then YC will help you navigate the big oil money people to help you get it out faster.
Metaphors are never perfect but I'm having fun with this one. :)
