Head of Marketing
Grant Belcher has deep experience across technology’s global giants. He began his career as a programmer, operator and analyst before shifting lanes when a fascination with brand psychology and the way people relate to technology took over. Grant has always been driven by understanding how things work and why people behave the way they do. That curiosity evolved into an obsession with effective branding. He focused on creating distinctive assets, memorable positioning and creative that removes every barrier, both physical and mental, between a brand and its customer. He believes this is the most predictable path to growth. The final piece was embracing AI not as a replacement for people, but as an amplifier that gives human creativity, strategy, empathy and nuance the scale and speed modern brands need.
