Spanish startup Uxia lands €1 million to develop synthetic-user technology for product teams

Uxia, a Barcelona-based B2B SaaS startup automating user testing with AI-generated synthetic users, has secured nearly €1 million in its first investment round, laying the groundwork for a potential Seed round within the next 12-24 months.

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

The capital injection – €750k in equity plus an additional Enisa loan expected to bring the total to €1 million – will fuel Uxia’s product development, talent acquisition, and international expansion.

“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 raise of nearly €1 million sits within a broader wave of European AI-driven B2B SaaS funding seen in 2025, where adjacent players such as Spanish startups Supersonik, which raised €4.2 million, and Anyformat, which secured €3.3 million, have also attracted early-stage capital.

Elsewhere in Europe, London-based Artificial Societies raised €4.5 million to advance its synthetic-persona platform for large-scale human-behaviour simulation, representing one of the few other 2025 fundraises in the broader field of AI-driven testing and behavioural modelling.

Collectively representing roughly €12 million in 2025 funding, these rounds point to sustained investor appetite for AI-enabled enterprise software across multiple verticals.

Within this landscape, Uxia – one of several Spain-based AI startups to raise this year – adds to a strengthening national ecosystem and reflects continued 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, Uxia is headquartered in Barcelona and operates globally. It currently resides in Barcelona Activa’s Startup Lab following selection into their acceleration programme.

The founding team brings product and technical expertise from major companies including Google, Gopuff, Shiji, and TransferGo. Díaz-Roig previously led Product Growth at TransferGo, while CTO Víctor Perdiguer was formerly leading technical integrations at Shiji Group and held AI-focused roles at Vonzu and NTT Data.

The company is focused on innovating a new approach to UX testing by simulating user behaviour with AI-powered synthetic profiles. This allows design teams to upload prototypes, define target personas, and receive usability feedback in minutes.

By eliminating the time-consuming and costly process of recruiting human testers and manually analysing sessions, Uxia aims to enable faster iteration cycles and broader accessibility to UX validation.

“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, who co-founded UserZoom (acquired for over €800 million), is joining Uxia as both an investor and advisor via Encomenda II. His knowledge of UX research and international go-to-market strategies is expected to be instrumental in shaping Uxia’s growth path.

Uxia counts clients from Europe, Korea, and the US, and the newly raised capital will be allocated to expanding product features – such as adding more test types, improving persona fidelity, and enhancing reports – while also growing its engineering, AI, design, and sales teams.

The company’s broader vision is to make AI-driven user testing a staple in every digital product development cycle, regardless of company size.
