I Need trick to get a list of apps with high traffic.

Hello,

does anyone here use CrunchBase or BuiltWith or similar website/tool?

I am looking for a free alternative or a trick to save costs.

All I need is, big list of apps with very high traffic(possibly with region, tech, contact etc).
Example: AirBnb, Shopify, Zomato, Olx, etc. I prefer rising startups.

Reason I need this... I develop high traffic applications. My current contract has ended and searching another potential customer.

TIA
