Here for the changemakers

Engineering a cleaner future. Pioneering a medical breakthrough. Reimagining education or rethinking what we eat. Rallying people around something worth fighting for. If this is the work you do, you're in the right place.

Tone Def. works with organisations doing work that actually matters: sustainable manufacturing and engineering, healthcare, education, clean tech, biotech, responsible food and beverage, and the non-profit and charity sector. We chose these spaces deliberately, because we believe good creative work should go where it can do the most good.

From brand identity and digital design to campaigns, content, and shoot production, we show up with the same energy, care, and belief in your mission that you bring every day, and help you tell your story in a way that's clear, creative, and genuinely you.

  • Ash Stott @Rhizo PTX

    The workshop we held with Tone Def. was worth its weight in gold. In just half a day, they helped us distil Rhizo PTX’s complex Power-to-X mission into a clear, punchy brand vision. The proposal they put together was massive in scope and incredibly professional. What really sets them apart is their model, which gives you the focus and agility of a freelancer but with the reliability of a full studio. The strategic clarity they provided acted as a massive catalyst for our internal team. They are truly a top-tier partner for any purpose-driven company.
