Hi. This is my idea for the logo. The green big circle is representing a huge business. But it is missing something which makes the circle incomplete. So there is the missing part, Opus, a small software ready to get into the big circle (business) to make it complete. The small circle and the font are in same colors so there wont be any confusion what the small circle represents. And the big circle also looks like a big O which is the initial of the product. Not to mention the simplicity. Hope you like this concept. Please rate and give feedback. Thank you.
