Why 85CO

/01

All output. No overhead.

Most AI startups don't need another generic dev shop or a tool that spits out templated UI. They need a partner who combines AI speed with senior human taste — so every brand, product, and automation feels intentional, not auto-generated.

85CO is one team that designs, builds, and ships for AI startups. The people doing the work are the people you talk to — no account manager relaying feedback, no project manager coordinating between silos.

The difference

Advantages

/06

Speed isn't compromise.

You get the speed of an AI-native studio with the quality of a seasoned global agency.

/01

AI-enhanced workflow

We use AI for research, wireframes, and code drafts — cutting iteration time by 40–60% without sacrificing quality.

/02

Human creative direction

Every deliverable is reviewed by senior designers. No fully autonomous AI output reaches your brand or users.

/03

Tech + creative team combined

One team handles brand, product design, and engineering — no coordination overhead between separate vendors.

/04

Built for fast-moving AI teams

Weekly demos, async-friendly workflows, and scope flexibility designed for startup velocity.

/05

Ethical, transparent AI use

We disclose AI usage in deliverables, avoid training on your proprietary data, and follow responsible AI guidelines.

/06

Flexible engagement

Fixed-scope projects, discovery sprints, or month-to-month retainers — no long-term lock-in required.

Zero lock-in — /07

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.

The team

/08

The people you talk to are the people doing the work.
