HeyDiga raises €5.5 million seed round led by 6 Degrees Capital for AI agents

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

HeyDiga, a Barcelona start-up building AI agents that handle conversations between companies and their customers, has raised a €5.5 million seed round led by 6 Degrees Capital (6DC). Kfund, Italian Founders Fund and Decelera joined, along with earlier backers including the Jobandtalent co-founders and a group of business angels.

Founded in July 2025 by David Zafra and Sergio Espeja, it raised €1 million at the end of 2025 and now has 15 employees and more than 200 active clients. Its platform fully automates over 78% of clients' conversations, which is a lot of phone calls nobody has to pick up.

The money goes to sales, sector-specific products and, above all, restaurants.
