Spanish startup Uxia raises €1 million to build AI-driven synthetic-user tools for product teams

The pre-Seed round was led by Abac Nest Ventures, with support from Encomenda VC and several angel investors, including Javier Darriba (UserZoom co-founder), Marsal Gavaldà (CTO of Clarity AI), and William Leppard (Director of AI at Oracle).

The company is receiving €750k in equity, plus an Enisa loan that is expected to bring the total to €1 million. This funding will help Uxia grow its product, hire new talent, and expand internationally.

“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,” says Borja Díaz-Roig, CEO and co-founder of Uxia.

Uxia’s pre-Seed funding of nearly €1 million is part of a wider trend in Europe, where more AI-powered B2B SaaS startups are raising early-stage capital in 2025. Similar companies include Spanish startups Supersonik, which raised €4.2 million, and Anyformat, which raised €3.3 million.

In the UK, London-based Artificial Societies secured €4.5 million to grow its platform that uses synthetic personas to simulate human behaviour at scale. This is one of the few other 2025 fundraises in the area of AI testing and behaviour modelling.

Altogether, these funding rounds add up to about €12 million in 2025, showing that investors continue to back AI-driven enterprise tools across different sectors.

In this environment, Uxia—one of several Spanish AI startups to raise money this year—strengthens Spain’s growing AI ecosystem and shows that there is strong interest in specialised AI productivity tools, even at the pre-Seed stage.

“Just as seatbelts became standard for every driver, not just professionals, Uxia will make continuous user testing an expected and effortless part of how every digital product is designed and launched,” adds Díaz-Roig.

Founded in 2025 and based in Barcelona, Uxia operates globally and is currently part of Barcelona Activa’s Startup Lab after being selected for its acceleration program.

The founding team has strong product and technical experience from companies like Google, Gopuff, Shiji, and TransferGo. Co-founder Díaz-Roig previously led Product Growth at TransferGo, while CTO Víctor Perdiguer worked on technical integrations at Shiji Group and held AI-related roles at Vonzu and NTT Data.

Uxia is building a new way to do UX testing by using AI-generated synthetic users to simulate real user behaviour. Teams can upload their prototypes, choose target personas, and get usability feedback within minutes.

By removing the need to recruit human testers and manually review sessions, Uxia aims to make UX testing faster, cheaper, and easier for more teams.

“Uxia fits perfectly with our thesis: AI-enabling, B2B SaaS, and global ambition. We see a clear opportunity to lead a new category in UX validation,” said Joan Pina Ollé, partner at Abac Nest Ventures.

Javier Darriba, co-founder of UserZoom (which was sold for over €800 million), has joined Uxia as both an investor and advisor through Encomenda II. His experience in UX research and global expansion is expected to play a key role in Uxia’s growth.

Uxia already works with clients in Europe, Korea, and the US. The new funding will be used to expand its product features—such as adding more test types, improving the realism of its synthetic personas, and upgrading its reports. The company also plans to grow its engineering, AI, design, and sales teams.

Uxia’s long-term goal is to make AI-powered user testing a standard part of building any digital product, no matter the size of the company.
