I'm starting a new enterprise in management consulting. For this new firm I'm looking for a great logo. The name of the firm is: HP2 (HP squared) with the slogan: Happy People, High Performance.
The logo should radiate the idea: Happy People perform better! The logo should create a feeling of FUN and CREATIVE, while still being PROFESSIONAL and TRUSTWORTHY.
The logo has to look great on a website as well as on a business card.
The main idea behind HP2 is to create an environment in which employees are encouraged to be happy, in order to achieve happiness and gain all the advantages it has to offer. Having happy employees significantly improves performance. Therefore the conclusion is: Happy People, High Performance.
HP2 will offer multiple consulting services, including change management, training, coaching and creativity sessions. The target groups are organisations looking for performance improvement, organisations who cherish and value their employees, organisations looking for a new competitive edge and organisations who value a good workplace.
