Built for AI startups.

85CO was founded on a simple belief: AI startups deserve creative and technical partners who move as fast as they do — without the generic look of auto-generated design or the overhead of traditional agencies.

We're a small, senior team based in Bucharest, working with founders worldwide. Every project gets human creative direction on top of AI-accelerated workflows, so your brand and product feel intentional from day one.

Start with a fixed-scope discovery sprint

Before any full engagement, we run a paid 1–2 week discovery sprint with a clear deliverable: scope document, timeline, and fixed quote. If you don't proceed, you keep all research, wireframes, and recommendations — no lock-in.
