In a marketing world where everything is increasingly measurable, data granularity sometimes acts as a blinder. 

Taking a step back to see the world from a wider or different angle, embracing context, empathizing with users and customers are all things we should do before making strategic decisions. It is not about being above. It is about understanding the big picture to discover perspectives and insights that will help create new ideas and solve problems.


With more than 20 years of experience in agencies as a strategist and in design & multimedia production as a freelancer, I decided to transition into a new adventure: 

A freelance consultancy. Also, marrying my international expertise in advertising (I worked for various brands across different industries and continents), with my insatiable passion for design, I created altitude in august 2018. 

altitude is at the intersection of design and strategy, dedicated to brands. It is offering 3 main services: strategic planning, design thinking and sonic branding.

"I have a passion for brands, strategy, culture, design and audio. And I strongly believe in the power of interdisciplinarity".  Guilhem Tamisier
