How we approach this

Most AI startup MVPs take 2–4 weeks to design and build with 85CO — from first wireframe to production deployment. We handle UX research, interface design, and full-stack development as one integrated team.

Why AI products need specialized design

AI interfaces are different. Users need to understand what the system is doing, trust its outputs, and recover gracefully when it fails. Generic SaaS templates break down quickly when you're surfacing LLM responses, agent actions, or probabilistic results.

We design for AI-specific patterns: confidence indicators, human-in-the-loop review flows, streaming responses, and clear error states — while keeping the experience fast and intuitive.

From concept to shipped product

Our product engagements follow a proven sequence:

  1. Discovery sprint — Scope definition, user stories, and technical architecture.
  2. UX & UI design — Wireframes, visual design, and interactive prototypes.
  3. Development — Full-stack build with AI integrations, auth, and deployment.
  4. Launch support — QA, performance optimization, and iteration based on real usage.

Design systems that scale

Every product we build includes a component library and design tokens your team can extend. This isn't throwaway MVP code — it's a foundation that supports your next 12 months of feature development without visual drift.

SaaS infrastructure included

We don't just design screens. Typical MVPs include authentication, user roles, subscription billing (Stripe), admin dashboards, and analytics hooks — the infrastructure investors and early customers expect from a serious product.

Common questions

Most MVPs ship in 2–4 weeks depending on scope. A focused dashboard with auth and one core AI feature is typically 2–3 weeks. Multi-role platforms with billing and integrations run 4–6 weeks.
