Construct 2/3 Companies?

I perceive Construct 2/3 as an engine for Indie developers or mini studio developers. Are there any bigger companies using Construct 2/3 to make games?

Yes, Construct 2 is professional and therefor used by lots of different big companies.

Construct 2/3 is excellent (maybe the best?) for in-browser HTML5 apps and 2D games, rapid prototyping, and education.

I think you'll find many bigger companies using it, even if their final products might be using another framework / engine to port over their ideas and designs for mobile/console/desktop release.
