What idea do you think would have the highest ratio in terms of how much money it would generate over how easy it is to build?
Just a thought exercise, not something you'd necessarily want to work on since it doesn't interest you. I'm not sure what my answer would be, but leaning towards something niche in adtech where there is still market share.
I agree. Definitely advertising. It will always be a need because there will always be consumers. Well, unless the market changes that is.
