Why Proportion

We don't fly in designers. We already live there.

For 18 years we've built the most decentralised community of 250+ innovation specialists in 68 countries across Africa, Latin America, South Asia and the Middle East.

01 / Rooted

Native innovation & design experts who understand context from lived experience.

Local design researchers cut through language barriers, cultural nuance, and field logistics that outsiders miss. Empathy isn't a workshop technique when it's your community.

02 / Close

Proximity means faster, cheaper feedback cycles.

Multiple rounds of user testing without multi-week logistics. Minimal travel, minimal CO₂, maximal iteration. Prototypes return to the field in days, not months.

03 / Systemic

Design 2.0 — beyond traditional HCD.

We combine human-centred design, systems thinking, futures foresight, business modelling, and social and behavioural insights to co-create solutions with users, communities, and the environment in mind. This approach helps organisations develop life-centred and community-led innovations that work within the wider ecosystem and are designed for self-sustainability and scale.

The Network

One network. Four continents. Sixty-two countries.

For every project, we assemble a tailored team from our vetted network of native innovation & design professionals. No two projects draw the same team, but every team has access to our shared knowledge base and past project experiences from across the world.
