Really love how our brand reveal video for Ona turned out. Good reminder that investing in sound design is worth the effort. It carries half the story.

For Ona, we created the ripple effect, a branded interaction inspired by the way water responds to touch. Calm, responsive, alive. While building the brand and product, we aimed to weave in these small moments of delight that make complex tools feel intuitive, human, and even a little joyful.

A glimpse of the motion design we at MAD created for the new Ona brand and product.

Part of a bigger journey where we worked across brand, product, and motion to bring Ona to life.

So cool to see parts of our brand work for telli up on Times Square. Always wild to spot something you worked on out in the world like that.

At MAD we are deep in brand and product design with the @gitpod.io team for their next chapter — Ona. A new kind of engineering agent, built for security and scale. More coming this year. ona.com
