Creating a suite of connected platforms and apps for a B2B SaaS.
As Head of Product Design, I collaborated closely with founders Will and Sam to reimagine a digital-first expert insights business. I led every aspect of the product design and build, even getting involved in the branding and first iteration of their website.
