Uxia secures nearly €1M to bring AI "synthetic users" into everyday product testing
Barcelona-based Uxia has raised close to €1 million to automate UX testing with AI-generated synthetic users. The pre-Seed includes €750k in equity led by Abac Nest Ventures, plus an ENISA loan expected to bring the total to €1 million. The funding will drive product development, hiring, and international expansion, setting up a potential Seed round in the next 12-24 months.
"After experiencing firsthand how difficult it is to validate product designs with real users, we decided to solve this problem for product designers and product managers. We do this through AI-generated user profiles that test your designs in a matter of minutes," said CEO and co-founder Borja Díaz-Roig.
How Uxia works
- Upload prototypes or flows.
- Define target personas with goals, traits, and contexts.
- Get usability feedback in minutes, plus reports that highlight friction and opportunities.
The goal: shorten validation cycles and remove the heavy lift of recruiting participants and manually reviewing sessions. For teams stuck between tight deadlines and limited research budgets, this is a practical way to test earlier and more often.
Why this matters for product teams
- Faster iteration: move from idea to tested design in the same sprint.
- Broader coverage: explore more variations and edge cases without extra logistics.
- Lower cost to learn: reduce spend on external recruiting and lengthy analysis.
- Better decision hygiene: keep evidence in the loop instead of shipping on opinion.
Use synthetic tests to de-risk early concepts, then confirm with human studies for nuance and depth. It's a practical way to front-load signal and reserve live research for the moments that truly need it.
Who's backing Uxia
- Lead: Abac Nest Ventures
- Participation: Encomenda VC
- Angels: Javier Darriba (co-founder of UserZoom), Marsal Gavaldà (CTO, Clarity AI), William Leppard (Director of AI, Oracle)
Javier Darriba joins as investor and advisor via Encomenda II. His UX research and go-to-market experience is expected to help Uxia scale internationally.
Market signal
Uxia's raise sits alongside other 2025 European AI-B2B SaaS rounds: Supersonik (€4.2M), Anyformat (€3.3M), and London's Artificial Societies (€4.5M). Collectively, roughly €12M has flowed into AI-driven testing and behavior modeling this year-pointing to continued investor appetite for tools that speed up product work without adding headcount.
Team, traction, and roadmap
Founded in 2025, the company operates from Barcelona Activa's Startup Lab and serves clients in Europe, Korea, and the US. The team brings product and engineering experience from Google, Gopuff, Shiji, TransferGo, Vonzu, and NTT Data.
- Near-term features: more test types, higher-fidelity personas, stronger reporting.
- Hiring: engineering, AI, design, and sales.
- Focus: make continuous user testing standard for every product team, regardless of size.
Where this fits in your process
- Discovery: validate problem framing and information architecture quickly.
- Design: compare flows, CTA placements, and copy variants before you commit dev time.
- Pre-release: smoke test critical paths and accessibility risks at scale.
- Post-release: monitor regressions and run quick checks on new segments or markets.

As Díaz-Roig puts it, "Just as seatbelts became standard for every driver, Uxia will make continuous user testing an expected and effortless part of how every digital product is designed and launched." If your team wants to ship faster without guesswork, this is the kind of tool to pilot early and bake into your weekly cadence.
