How to grow by getting a pie from competitors' market share?

Regardless of your industry, we all know that every company has at least one competitor. And with the help of the digital world, it's getting easier to find each player.

And, IMO we need to be transparent about our product as high-potential buyers check each testimonial and other competitors.

When we say transparent, I imagine comparison pages, and there are some players that are close to being transparent such as Pipedrive, Monday and UserGuiding.
