AI product interface and brand work by Brand Appart

An AI design agency for startups building with AI.

Brand Appart designs the brands, products, websites and pitch decks of AI startups, and works with AI every day to do it faster. Senior designers make the calls, AI takes the repetitive work. For funded teams from seed to Series B.

An AI design agency can mean two things. We do both.

Some founders look for an AI design agency because their product runs on AI: a model behind the interface, answers that change from one request to the next, buyers asked to trust an output they cannot easily check. That product needs design for uncertainty, not a standard SaaS template with a chat box added.

Others mean a studio that uses AI to work faster than a classic agency. We are that too: AI turns design tokens into code, produces variants and first drafts, and follows brand rules written for it. The decisions that make a brand recognizable stay with senior designers.

Designing for AI products,
designing with AI

For AI products, the work starts with trust. We design the patterns that make probabilistic features usable: setting expectations before the first prompt, showing progress while the model works, making every output editable, citing sources, designing the failure states first, and keeping the human in control of any action with consequences. We wrote up these six patterns in our guide to AI product design. For Reecall, a voice AI company that automates phone calls, we rebuilt the brand and the Webflow website around its pivot from end-user SaaS to a platform that software vendors embed in their own products.

In our own workflow, AI does the translation and repetition work. We keep Figma and code in sync with Claude and GitHub (how we scale design systems), set up a Brand Brain so AI tools write and produce on-brand, and our AI creative studio makes launch films with generative AI in the pipeline, like the one for Promethee. For ongoing requests, the AI creative team works on a monthly subscription.

What our AI design agency does

Four ways we design for AI startups

AI Product & UX Design

Interfaces for AI features and agents: prompts, streaming states, editable outputs, sources, confidence and fallbacks. Designed so users trust the output enough to act on it.

Brand Identity for AI Companies

Positioning and identity that lead with what the product changes for the buyer, not with the model behind it. Built to stand apart in a category where most brands look alike.

Websites & Pitch Decks

Webflow sites and seed to Series B decks that explain a technical product to buyers and investors in plain terms.

AI-Native Design Workflows

Design systems kept in sync with code, brand rules your AI tools can follow, and generative production for films and campaigns, set up so your team keeps using them.

Why AI startups
work with us

One senior team.

Brand, product, website and deck from the same senior designers.

No handoff between an AI vendor and a design agency.

Design for uncertainty.

We design the states most teams skip: slow answers, wrong answers, low confidence.

Those screens do more for retention than the happy path.

AI where it earns its place.

We use AI for code, variants and drafts, and tell you where.

Brand decisions stay human.

Built for funded startups.

Seed to Series B, in B2B SaaS, fintech and Deeptech & AI.

Work planned backwards from your round or your launch.

Notez-Nous chose Brand Appart to lead our rebranding project, including a full website and platform redesign. The boost in credibility has significantly improved our ability to close deals
David KatzCEO & Founder @Notez-Nous
We'd seen other agencies lock everything down two rounds of feedback, then pay more. With Brand Appart, the flexibility was real. That's why we chose them. The quality of the work speaks for itself. The rebranding landed exactly where we wanted it to, and the feedback we've gotten externally has been overwhelmingly positive. We're a demanding team, with moving targets and tight timelines. It still went well. That says a lot.
Sébastien TomiCO-Founder & CEO @Mysunbed
We knew Brand Appart's work before reaching out the creativity was obvious. And the final result delivered exactly that. The team adapted to how we work: fast, informal, no unnecessary calls. That made the whole collaboration genuinely smooth. What stood out most was the quality of the output. When we saw the new version, the whole team was back in love with the project. That kind of energy is hard to manufacture it just happened naturally. We're very happy with what was built.
Yoann RosCMO @Bricks
I’ve worked with Brand Appart on multiple projects website development, landing pages for branding, and PowerPoint presentations. I love how flexible, fast, and professional the team is. That speed and agility are exactly what we needed at Ircam Amplify.
Alexis BotayaManaging director @Sound Experience
We had a family brand that hadn't evolved since 2013. Handing it over to an external agency was a real leap of faith. What struck me most is that the team held their ground without ever steamrolling mine. I pushed back on certain directions early on. They stood firm, explained their choices, reassured me and looking back, they were right. Feedback is well received, adjustments are fast, and you can tell the team genuinely enjoys working on the project. That makes all the difference. We're now moving into a year-long collaboration.

Frequently
asked questions

What is an AI design agency?

The term covers two things: an agency that designs AI products, and an agency that uses AI in its own design process. Brand Appart does both. We design the brands, interfaces and websites of AI startups, and we use AI tools for code, variants and production, with senior designers making the decisions. Our Deeptech & AI page covers our work in the sector.

Do you design AI features inside existing products?

Yes. Many startups add an AI feature to an existing SaaS or fintech product. We design how it fits the current interface: where it appears, what it can and cannot do, how users review and edit its output, and what happens when it fails.

Which AI tools do you use?

Figma for design, Claude for code and documentation work, GitHub to keep the design system and the codebase in sync, and generative image and video tools for production. We compared the main platforms in our guide to the best AI design platforms for creative teams.

Will the work look AI-generated?

No. AI produces options and handles repetitive work, and a senior designer chooses, refines and finishes everything you see. The brand rules we write for AI tools are there to keep their output consistent with your identity, not to replace it.

How is this different from your AI creative team and AI creative studio?

This page covers the full design engagement for an AI startup: brand identity, product design, a Webflow website and a pitch deck. The AI creative team applies the same approach on a monthly subscription for ongoing requests, and the AI creative studio makes launch films and campaigns by project.

How much does an AI design agency cost?

It depends on scope: brand, product, website and deck can be scoped separately or together. We scope it on a first call and come back with one number. Our pricing page explains how engagements are scoped.

Do you work with AI startups outside France?

Yes. Brand Appart is rooted in Paris and works fully remote, in English, with clients across Europe, the US and the Middle East.
