Top 9 AI Product Design Agencies That Build More Than Just Prototypes

Most AI products can pass a demo. Fewer can make people come back a second time. The gap isn’t in the models — it’s in the design.

We went deeper than the usual SEO lists to find agencies that are setting the bar for what real AI experiences should feel like. We reviewed case studies, dug through client feedback, and evaluated whether these teams could push AI products beyond the prototype stage.

The result is a short list of 9 AI design agencies that know how to ship, not just show.

1. Cieden: best for data-driven AI UX design for B2B & SaaS products

When AI feels slapped on, Cieden is the team that makes it feel like it was there from day one. Founded by a design professor who swapped the lecture hall for the real world, Cieden’s specialty is translating complicated tech into interfaces people enjoy using.

They’re the crew behind Blizzard’s streamlined CMS, Apollo’s hyper-personalized AI messaging, and a desktop lie detector that makes AI sentiment analysis feel surprisingly natural.

With 47 team members across seven countries, this AI product design agency brings serious brainpower to every project, whether that's slicing five-step workflows down to two clicks or transforming dry data platforms into user magnets.

Case studies and portfolio overview

• Desktop lie-detector software: Rebuilt scattered desktop apps into a unified investigation console and introduced an AI-driven sentiment-analysis module.

• Apollo: Reimagined the UI for this sales-tech platform and prototyped hyper-personalized AI messaging flows.

➕ What clients love

• Measurable growth fast: Clients report 4× audience growth, +35% traffic, 12% lower bounce rate, 119% more leads after the redesign.

• AI made easy: They translate complex ML models like sentiment analysis and language generation into simple UX that needs almost no user training.

• Steady process: Workshops, story maps, and regular demos keep teams aligned without slowing things down.

• No hand-holding needed: Designers stay in shared Slack channels, respond fast, and hand over files on schedule.

⚠️ Where they could improve

• No in-house developers: Developers are partners of the company, though Cieden can help manage them.

• Scope planning: Mid-project feature creep can raise costs, so set priorities early.

• Documentation depth: Some reports are ultra-detailed — good for PMs, maybe too much for exec overviews.

2. The Gradient: best for GenAI‑powered consumer & fintech products

From an AI coach that identifies your work style to a video‑analytics platform that interrogates its own footage, The Gradient designs products where large language models, behavioral science, and visual systems collide.

Spreading their AI design expertise globally, these folks are on a mission to make sure the AI revolution comes with an instruction manual the rest of us can actually understand. 

Their UX design and AI team has designed award-winning interfaces for fintech and consumer products, earning back-to-back UX Design Awards (’24 & ’25) for Cashee and Lumiere.

Case studies and portfolio overview

• Lumiere (Latitude): Created an AI-powered video intelligence platform that helps understand audience reactions. This project won Gold at the London Design Awards.

• Cashee: Designed a digital banking platform for teens in the MENA region. The AI design earned a UX Design Award and is among the 25 most downloaded finance apps in KSA.

• Happy: Built a coaching platform that uses behavioral science to improve team dynamics. The system analyzes work styles and provides personalized guidance.

➕ What clients highlight

• Results you can pitch: IN1 App broke 100k transactions in three months; Cashee leapt into KSA’s Top‑25 finance apps post‑launch.

• Award‑magnet design: Interfaces consistently recognised by international juries.

• Structured process: Stakeholders note the team’s methodical discovery and sprint cadence.

• Responsiveness: Designers stay accessible in shared channels and hit agreed delivery windows.

• International design sensibility: Interfaces feel “world‑class” and resonate with users across regions and cultures.

⚠️ Where they could improve

• Project management formalization: One client wanted more formalized project management, but also noted that it didn’t detract from their service.

• In-house development: They don’t code. You’ll need your own dev team (or one of their trusted partners) to build the product.

• Documentation rigor: Hand‑off files cover the essentials, but large enterprises sometimes want more exhaustive specs and test logs.

• Deeper technical expertise: Their strength is in product strategy and UX; if you need web engineering guidance, plan for an additional specialist.

3. Lazarev: best for data‑heavy SaaS and Web3 tools

Lazarev turns “almost‑there” ideas (like data‑heavy SaaS or AI widgets) into click‑ready interfaces your users can figure out in ten seconds flat.

This AI product design agency started in Kyiv, set up a second home base in San Francisco, and now runs on a 30‑person team who have already racked up three Webby Awards.

In the past nine years they have shipped 500+ products, helped clients land more than half‑a‑billion dollars in funding and seen one redesign (Peel) exit to Shopify. If investors keep asking, “Can we demo next quarter?”, this is the crew that can shorten that timeline to weeks.

Case studies and portfolio overview

• VTnews.ai: Designed an AI news‑bias tracker that attracted 85,000 readers in eight months and achieved 90% user trust in bias scoring.

• Accern Rhea: Created an AI research assistant that compresses a day of financial data digging into minutes. 

• Blockbeat: Transformed an early-stage crypto news aggregator into a comprehensive trading terminal.

• Structured process: Their structured approach keeps projects organized, with fewer surprises along the way.

• Communication that feels easy: Clear updates, quick replies, and a no-drama attitude make collaboration smooth.

• Measurable results: One blockchain client saw website traffic increase by 120% after launching their redesigned site. 

⚠️ Where they could improve

• Team size shifts: They’ve slimmed down by about 37% over two years, which could stretch timelines on larger projects.

• Clearer budget setting: Pricing is premium, and a little more upfront clarity would make planning easier for some clients.

• Faster file handoffs: A few clients mentioned final Figma ownership transfers taking longer than expected.

• More project management: Their creative side is strong, but adding heavier PM layers would make fast-moving projects even smoother.

4. Reaktor: best for end-to-end AI‑powered digital transformation

With teams from Helsinki to New York, Reaktor has spent years using AI for product design and turning "sounds impossible" into "ships next month." 

They’re the ones behind K Group’s 400% online sales spike and the inflight experience used by 40M+ Cathay Pacific passengers.

A steady global growth trajectory and trophy cabinet hint at why Fortune 500s keep calling, but what really sets them apart is their culture – where summer interns are treated like full team members and hobby clubs (570+ on their Slack!) build the community that powers their work.

Case studies and portfolio overview

• Kesko (K Group): Built a nationwide grocery & content platform with 400% sales growth.

• Orion: Created a GenAI tool for pharmaceutical research that summarizes complex documents.

• Innovation that works: AI implementations deliver measurable results rather than just flashy demos.

• Industry knowledge: Their AI teams understand vertical-specific challenges across retail, healthcare, and more. 

⚠️ Where they could improve

• Premium pricing: Higher rates may challenge lean‑budget initiatives.

• Varied team fit at scale: With 700 staff and six offices, chemistry and seniority can differ, so it’s better to insist on meeting the exact squad before kickoff.

• Time‑zone overlap: Core delivery sits in UTC +2, so West‑coast teams need planned touch‑points to avoid late‑night stand‑ups.

5. Momentum: best for accelerating digital health solutions

Momentum is putting rocket boosters on the most ambitious digital health ideas. With deep expertise in AI design, HIPAA-ready infrastructure, and EHR integrations, this Poland-based team is a great choice for companies scaling in the notoriously complex healthtech space. 

Their ISO 13485 certification and open-source frameworks help clients cut costs without cutting corners — even in highly regulated environments.

Case studies and portfolio overview

• Villa Medica: Designed an AI-powered transcription that saves clinicians 3+ hours a week and improves patient volume by 15%.

• Enterprise reach: Strong in mid-market; less traction with large enterprise deployments.

• Geographic spread: Mostly EU-based; North American coverage could improve.

• Operational polish: Strong on tech and communication, but a few clients flagged room for improvement in how admin details are handled.

6. Fantasy: best for humanizing artificial intelligence

When Natural needed an operating system built entirely on AI, they called Fantasy. When Rokid set out to make smart assistants feel emotional instead of robotic, Fantasy built it.

Since 1999, this global AI design team has been quietly shaping how billions interact with intelligent tech, designing interfaces for giants like LG and Huawei while inventing new ways for humans and machines to connect. 

Fantasy has spent decades mastering the toughest challenge in artificial intelligence: making complex systems feel so intuitive that users forget they're interacting with machines at all.

Case studies and portfolio overview

• Natural OS: Built an operating system powered entirely by AI, designed to feel natural and human.

• Huawei EMUI: Designed multiple OS generations for Huawei, helping them lead globally in smartphone UX.

Whether it’s a quick AI feature add-on or a full-scale product launch, Linkup combines creative thinking with technical depth to ship tools that users stick with.

Case studies and portfolio overview

• Wholesum: Group meal planning tool with AI recipe generation, now used by outfitters and summer camps across the U.S.

• Delfi Labs: Financial risk management platform that runs thousands of market scenarios in seconds, reducing volatility by up to 99%.

• Market understanding: Some clients note they could improve understanding of specific local markets. 

• Language barriers: Occasional communication challenges due to language differences.

8. Koncepted: best for subscription-style, next-day design

This Puerto Rico-based collective designs AI-first interfaces that break from the usual startup sameness. Their pattern is to take something technically gnarly, like ForumAI’s DePIN tech or TRVL’s blockchain booking, and make it feel intuitive, even inviting.

Koncepted has baked continuous AI design into their process. Next-day turnaround. No hiring overhead. Just a dedicated AI product design squad on call. Their tiered subscription model lets startups scale to full product launches with no delays, just execution.

Case studies and portfolio overview

• PalmID: Designed the UX for a privacy-first biometric tool using palm scans. 

• TRVL: Reimagined travel booking with a Web3 engine and familiar UI.

➕ What clients highlight

• Full creative stack: Product, brand, motion, and 3D — all under one subscription, no extra vendors.

• AI-native design thinking: Designers who speak LLM prompts and on-chain logic fluently.

• Predictable pricing: Subscriptions replace hourly surprises with fixed, scalable design support.

⚠️ Where they could improve

• Design-only scope: Teams without in-house engineers will need to staff development separately.

• Scaling limits: Parallel-request caps mean large-scale launches may require the top-tier plan.

• Award recognition: Fewer public design awards than longer-established studios.

• Leadership visibility: Senior team presence is limited in public-facing content.

9. NineTwoThree AI Studio: best when you need a complete AI product

NineTwoThree AI Studio is a Boston-based “venture-studio-as-a-service.” 

They’ve launched 14 internal startups and 150+ client products (several have passed $1B in cumulative value), which shows in their client work. Consumer Reports’ conversational AI, SimpliSafe’s AI crime-prevention tools, and FanDuel’s viral "ChuckGPT" campaign all have their fingerprints on them.

Their AI design playbook routinely gets an idea into production in ≈ 5 months and pays for itself in the first year.

Case studies and portfolio overview

• ChuckGPT (FanDuel): Turned Charles Barkley’s personality into an interactive AI experience, complete with OpenAI and ElevenLabs integrations.

• AskCR (Consumer Reports): Built a conversational AI that turns product databases into live, human-like recommendations. Powered by an RAG system.

• Technical firepower: Especially strong with device-connected apps, IoT, and complex systems integration.

• Founder involvement: Leadership stays hands-on, not just for kickoff calls but across the whole build.

⚠️ Where they could improve

• Premium pricing: Higher rates can stretch leaner startup budgets.

• Selective intake: They’re picky about which projects they take, so expect a queue.

• Prototype polish: Early builds sometimes need extra QA rounds.

• Light documentation: Fine for most teams, but might fall short for strict enterprise compliance.

The methodology behind our top AI product design agency picks

For this list, we didn’t just grab agencies with “AI” somewhere on their homepage. We focused on teams that know how to build real AI experiences. Here's how we approached it:

• Reputation & reviews: We looked for agencies with strong Clutch ratings (4.9+ where available) and real-world client feedback about AI-driven projects (no general UX praise).
• AI integration expertise: We prioritized teams that could show more than surface-level AI use. We wanted examples of LLM integration, AI UX design, explainable AI, and real-world adoption, not just “coming soon” features or concept art.
• Portfolio proof: Case studies mattered. We checked if these agencies had shipped live AI products, whether it was sentiment analysis platforms, AI-powered SaaS tools, predictive systems, or full GenAI-powered experiences.
• Results: We picked agencies that helped clients move from idea to impact, meaning better retention, faster adoption, measurable business results, or even funding wins.
• Process & collaboration style: Because AI projects evolve fast, we favored agencies with a proven, flexible design process — workshops, rapid prototyping, shared Slack channels, frequent demos.
• Differentiators: Each agency earned its spot by standing out: deeper research practices, technical fluency, niche AI verticals, faster time-to-market, or unique ways of humanizing machine intelligence.
