Hi Riza,
Now that we placed you as designer in our 'top 5' (#81), we would like to blend your ideas with our insights:
We received a lot of logo's with 'brains/head/human-being'. Some logo's tell a lot in one image.
Some worked on the side 'business'/'profit. we like that way of thinking.
But to appeal to the board-level we need simplicity, an ease to understand logo that appeal to decision makers.
Background: we're persuasion 'engineers' not just 'designers'; we create the best persuasion architecture/tactics for big companies on boardlevel and deliver the best high-end designs to make it work...
Could you focus on simplifying? Brains/human is still interesting, but it's ok to focus on designing the word BuyerMinds with a more minimal logo / only word-logo without icon? Don't feel restricted to the colors. We in hinsight feel we shouldn't have put down our colour demands so rigidly.
We hope you can give it another swing! Please ask us any question. Thanks.
