Can I use other companies logo's on my site if they're paying for my app?
I've noticed a tonne of people operating in the space I am in do this (even relatively smaller ones where I can't imagine)
I'm curious if anyone knows the requirements for showing a companies logo on my site? Is it something that's going to require legal right off?
If those companies have trade marketed their logos, which in must cases they will have, you probably need
their permission to use their logos. To know for sure check out their terms and conditions, in these documents companies often lay out the rules to use their logos.
