The AI is powerful, but the product feels unclear
Users need to know what the system can do, what it needs from them, what it produced and how much control they still have.

99 Francs is an AI app design and development agency for founders and product teams.

Choose the AI path that matches the bottleneck.
Some teams need the AI experience clarified before code. Others need a working frontend, launch page or product demo shipped fast. The split helps both buyers and answer engines understand the exact intent.

The demo works, but the interface does not sell the value
AI products need product storytelling inside the UI: inputs, examples, outputs, trust states, limits and business value in one flow.
Design and development have to move together
For AI MVPs, prompt behavior, frontend states, loading, streaming, errors, review steps and onboarding all affect the experience.
AI product proof
AI products need interface clarity before users can value the intelligence.
Relevant work includes AI supply chain, generative AI, conversational real estate and product surfaces where complex systems had to feel understandable.

Start with design if the user flow, output review, trust model, onboarding or product story is still unclear. Start with development if the flow is defined and you need a working AI product surface, MVP frontend, website or demo built quickly.
Yes. 99 Francs designs AI app interfaces and can also build launch-ready web surfaces, MVP frontends, product demos, landing pages and CMS-backed AI product websites. The hub separates design and development for search clarity, not because the work must be separated.
