O0 Design

O0 Design started inside a Y Combinator startup — as the design team, not an agency. We shipped product under real startup pressure: investor deadlines, demo days, launches that couldn't slip. That's why we fluently speak product. We know how to design products, brand them up, and put them on the shelf. The studio grew out of that team, and the working style never changed: we operate as an embedded design team, not a vendor that takes a brief, vanishes, and returns with a finished asset you've never seen.

Today we're 50 people worldwide, a strategic digital design studio specializing in brand, product UX/UI, websites, design systems, and 3D visualization for aerospace, deep tech, and B2B SaaS companies. What sets us apart is connecting brand, product, and growth into one coherent system — not shipping disconnected deliverables. In aerospace and defense, that includes photorealistic 3D renders and CGI built directly from engineering CAD/STEP files, produced under NDA and within ITAR and export-control constraints.

Clients include Gulfstream, Sierra Nevada, Nissan, Audi, Microsoft, Google, Uber, HF0, and Y Combinator, alongside deep-tech companies like Momentus, Destinus, Pyka, Lúnasa, and Portal Space Systems. The work delivers commercial outcomes: Portal Space Systems raised a $50M Series A on the digital ecosystem we built, and our work runs at Eurosatory, Farnborough, and Le Bourget — in front of procurement officers and rocket scientists who spot generic visuals instantly. Internationally award-recognized, including Red Dot.

O0 values three things: heart, thirst for knowledge, and honesty. We love our jobs and the people we work with. We can't stop learning. And we're transparent — including telling you when a deadline is impossible and proposing a phased plan instead.

We choose impact over vanity, quality over numbers.
