For me, it's a guy named Marko Lazic who's building luccid.ai, which allows you to design your dream home. The reason why it's Marko is that he had to overcome a lot of challenges to get to where he is now and he's also building a kickass product to disrupt an old-school industry.

maching.ai helps job seekers find their dream jobs by chatting with an AI chat-bot that makes recommendations based on their interests, past job experiences, and job role desires.
