Ask HN: Can you make a living as solo founder in the Data Mining space?

Hello Hackernews, i am interested in all topics around Data Mining. Scraping, crawling and Data processing are big topics in my free time.

Do you know any small company < 2-3 people or solo founder who can make a good living with it?

I know only https://builtwith.com . This would be my personal dream job / company.

Big Thanks
