As it is stated in the topic, I am looking for design and marketing experts willing to share their expertise in tech company branding.
Here's the list of questions to give a more precise idea (the questions, of course, differ, depending on an expert's role in the company):
How did you come up with the idea of the logo?
Speaking of color choice - why did you pick the ones, used now?
What is the key message you want the design to convey?
What is the general impression/associations you think visitors have from the brand?
If you were to give advice to a tech company/startup, working on their own branding, what would it be?
How do the current logo, design and tagline reflect the main values of your company?
