Castellón start-up Niubiq raises €410,000 seed round led by Juan Roig's Angels

The story so far, in brief; the legwork, and the full article, stay with the original outlets.

Niubiq, a sales-intelligence start-up based in Castellón de la Plana, has closed a €410,000 seed round led by Angels Capital, the investment company Juan Roig runs as part of Marina de Empresas. Club de Inversión Órbita and Elephant also took part and join the shareholder register. No valuation was disclosed, which at this size is less a secret than a custom.

The product addresses a familiar corporate puzzle: companies usually know how many leads come in and how many turn into customers, and rather less about what happened in between. Niubiq traces each lead from the campaign that brought it in to its final contact with the company, pulling together calls, video calls, in-person meetings, WhatsApp and email to work out why some convert and others quietly disappear. "Companies invest a lot in capturing leads and very little in understanding what happens to them afterwards," said chief executive Gonzalo Bravo. The money will go to strengthening the company's structure and team so it can consolidate and scale.

Niubiq has been through Lanzadera, the accelerator that sits alongside Angels and the EDEM business school inside Marina de Empresas, so the lead investor was not exactly a stranger. It was also among the start-ups recognised in CEEI Castellón's Órbita acceleration programme, whose investment club is now in the round, and is in the Top 100 of the VDS Startup Competition 2026. Angels says it has invested more than €40 million in 70 companies since it was created.
