Digital product design & development
Kime is a three‑person collective: a designer, a product manager, and a developer ↦ With complementary skills, we cover the full spectrum of needs across the digital product lifecycle.
We put our skills to work on projects that make the digital world more empowering, sustainable, and desirable.
Our approach to product design
Useful products start with understanding users. We begin with design research and keep learning throughout the project. We run qualitative and quantitative studies across the product cycle to ground decisions in evidence.
Desirable products are crafted. We co‑create with users, test early and often, and refine continuously. Short feedback loops and iterative design help us ship better outcomes each time.
Simplicity—removing the non‑essential—is central to our practice. Clear, easy‑to‑use products improve accessibility for everyone and reduce environmental impact.
We favor free and open‑source building blocks without vendor lock‑in. You stay in control of your project and your data. Hosting is provided by trusted partners based in France or Europe.
Our services
We tailor our involvement to your needs. Our collective can also scale with a trusted network of independents when projects require additional expertise.
