Madrid, April 29, 2026 — Technology startup TietAI has announced the closing of a €2.5 million seed funding round to accelerate the development of Hydra, an Artificial Intelligence layer designed to power hospital healthcare operations, from data ingestion and clinical workflow orchestration to care transitions, scheduling, billing, and laboratory interpretation.
The funding round was co-led by Plus Partners and JME Ventures, with participation from Banco Sabadell’s BStartup, Archipiélago Next, and a group of business angels. The goal of the round is to expand the engineering team; accelerate certified deployments in Spanish and European hospitals; and develop new operational agents in areas such as clinical scheduling, diagnostics, care transitions, billing, and laboratory interpretation.
“With this round, TietAI consolidates a new category: AI platforms for healthcare operations,” says Roberto Cruz, CEO and Co-Founder of TietAI. “The funds will allow us to expand the team, accelerate deployments in Spanish and European hospitals, and be ready for major regulatory milestones — the European AI Act and the European Health Data Space, EHDS — with a proposal that is not theoretical, but already working. It is the right time, with the right investors, to build European infrastructure from Europe.”
“Behind TietAI is a team with an uncommon combination of technical talent and an obsession with solving real problems in hospitals. TietAI is the best option for artificial intelligence to help doctors and healthcare teams every day. They reduce administrative burden, give more time back for patients, and ultimately create a better experience for everyone,” says Enrique Linares, General Partner at Plus Partners.
Technological transformation, scalability, and internationalization
According to David Rey Blanco, COO and Co-founder of TietAI, the Spanish company’s goal is to transform the technological foundation on which hospitals operate. “For decades, hospitals have used electronic health records and isolated tools, but they have never had a true unified operational layer,” Rey states. “Hydra was created to become that invisible infrastructure that allows everything to work in a coordinated and reliable way.”
TietAI began operating from Madrid and already has an international presence in Estonia and Serbia, consolidating a growth strategy focused on the European market and aligned with the European Artificial Intelligence Act, as well as the European Health Data Space (EHDS).
“AI in hospitals will not fail because of a lack of AI models; it will fail because of a lack of accessible and interoperable data. TietAI is building precisely that layer, just as European regulation makes it mandatory. We believe TietAI can become the infrastructure on which intelligent healthcare will be deployed in Europe. In addition, Roberto and David combine something unusual in the European ecosystem: real technical depth in healthcare data integration and operational experience scaling data and AI products at leading companies,” says Samuel Gil, Managing Partner at JME Ventures.
