I'm confused by the idea that this is bad in some way. The point of business is to make money. For startups in particular, the entire commercial goal can roughly be broken down into one of three things:

1. Build a lasting private business (Mailchimp) 2. Go public (Facebook) 3. Get acquired (Instagram)

Obviously, I'm ball-parking here, but 99% of startups with "successful" outcomes happen via acquisition. For the vast majority of most startups, acquisition is the only viable outcome other than failure.

Care to expand? Are there companies doing business while being a non-profit? I’m interested in starting a business but as a way to help a charity or foundation of some aspects close to my heart.

Edit: thought about St. Jude’s hospital but it depends on donations.

>> only trust a not for profit organization

Not a very good heuristic, people always find ways to profit from so-called 'non-profits'.
