Madrid's HeyDiga raised €5.5M in seed funding led by UK firm 6 Degrees Capital to deploy AI agents automating phone, WhatsApp, and live chat for businesses.
Key Takeaways
- UK fund 6 Degrees Capital led the round; K Fund, Italian Founders Fund, and Decelera also participated
- HeyDiga claims its system automates 78% of incoming business conversations across 200+ clients
- Founded in July 2025, the company has now raised roughly €6.5M in total after a €1M seed in late 2025
Lead
Madrid-based HeyDiga closed a €5.5 million seed round on September 10, 2026, led by London-based 6 Degrees Capital, with participation from K Fund, Italian Founders Fund, and Decelera. The 14-month-old startup builds AI agents that field inbound calls, WhatsApp messages, and live chat on behalf of small and medium-sized businesses - handling customer service without replacing a brand's voice.
The round brings HeyDiga's total funding to roughly €6.5 million, following a €1 million seed closed in December 2025 led by K Fund alongside the founders of Spanish employment platform JobandTalent.
What Does HeyDiga Actually Build?
The product is an AI layer that sits between a business and its customers across every real-time channel. Conversational agents are trained to match each client's tone and integrated directly with the tools those clients already run - booking systems, CRMs, restaurant management software, automotive dealership platforms. When a customer calls, messages, or chats, HeyDiga's agent handles it.
The company says its system resolves more than 78% of incoming conversations without human escalation. Roughly 200 business clients are live, spanning automotive retail (Audi, Seat, Toyota, Triumph), hairdressing chains (Marco Aldany), and the hospitality sector (East Crema Coffee). The next commercial push targets restaurants specifically, where after-hours booking inquiries and unanswered calls represent high-frequency, low-complexity work that AI handles cheaply.
Investor Lineup
6 Degrees Capital, which closed a €154 million fund earlier in 2026, came in as lead rather than a supporting participant - a distinction that matters in early-stage rounds where lead investors take board seats and set the tone for future raises. K Fund returns from the December 2025 round, a signal that the prior backers see the traction as real.
The cap table also includes the founders of JobandTalent alongside operators from Docplanner and Spanish tech law firm Delvy. Those names are less about capital and more about access - direct routes into the HR, health, and legal verticals where HeyDiga's product could extend.
Why Is Spain a Useful Test Market?
Spain's SME sector is dense and service-heavy, with persistent customer contact volume across hospitality, automotive retail, and personal care. WhatsApp penetration sits above 90% of smartphone users in the country, making it a live customer service channel that most small businesses handle inconsistently or not at all.
For HeyDiga's founders - David Zafra, who came through Tuenti and Hawkers, and Sergio Espeja, a JobandTalent alumnus - the home market provides a concentrated proving ground. A system built to manage dealership intake calls in Madrid is handling a use case that replicates across every mid-sized European city. The harder test is whether it generalizes cleanly across languages, cultural communication norms, and regulations that vary by country, particularly for AI-generated voice interactions.
What Does 78% Automation Mean in Practice?
HeyDiga's headline metric invites scrutiny. Automation rates depend heavily on scope: whether a resolved conversation means a booking confirmed, a FAQ answered, or simply a request logged and closed without a callback. The number looks strong; the methodology behind it is not public.
That caveat aside, the metric drives the core unit economics argument. If a single AI agent can handle the intake volume of one full-time receptionist across several clients simultaneously, the pricing math works at the SME tier. If edge cases pile up and human escalation climbs, the efficiency case compresses quickly. With 200 paying clients and live call volume, HeyDiga has at least cleared the demo phase - the 5.5x step-up from its December round suggests investors agree.
Outlook
HeyDiga will deploy the new capital to expand its commercial team and deepen integrations in the restaurant vertical, where the volume of unanswered calls is highest and where a platform hook into reservation software creates defensible stickiness.
The company is 14 months old with €6.5 million in total funding and 200 clients, operating in a crowded market where competitors range from horizontal chatbot builders to vertically focused voice AI platforms in the US and UK carrying significantly larger war chests. The next 18 months will determine whether HeyDiga's early SME traction in Spain is a foundation for European expansion or a ceiling.
