Irish Sisters' AI Start-Up Linda AI Raises €2.6m to Automate Dental Practices Across UK and Ireland
A Dublin-based health-technology start-up founded by two Irish sisters has raised €2.6 million in pre-seed funding to expand its AI-powered voice platform, which automates front-desk operations for dental practices across Ireland and the United Kingdom.
Background
Linda AI was founded by sisters India and Portia Healy O'Connor, along with CTO Lucio Tudisco. The company developed its platform after identifying a critical problem in dental practice management: most clinics miss more than a quarter of inbound calls, costing a typical four-surgery practice more than €10,000 in lost revenue every month. The start-up is an alumna of the NDRC Accelerator in Dublin.
Key Developments
The €2.6 million pre-seed round, announced in February 2026, was led by 6 Degrees Capital, an early-stage investor with offices in London and Antwerp that focuses on fintech and B2B SaaS. The relationship with the investor began during a female-founder event in London as part of a Fierce Women in Tech programme.
Linda AI's platform uses voice, text, and system integrations to handle overflow and out-of-hours calls, confirm appointments, manage rescheduling, and complete bookings. It integrates with existing practice management software and communication systems, working alongside front-desk teams rather than replacing them.
Early results from partner clinics have been striking: approximately 25% of new patient bookings now come through the AI system, practices report a 15% increase in total bookings, a drop of over 30% in failed-to-attend rates, and front-desk teams save more than ten hours of administrative time per week. The platform is currently live in over 50 locations across Ireland and the UK.
Why It Matters
The adoption of voice AI in service-led industries is growing at approximately 35% annually, with vertical AI systems tailored for specialist sectors gaining significant traction. Linda AI is positioning itself as a category leader in dental practice automation, with 6 Degrees Capital describing the company as "well-positioned" to dominate this evolving space. The new funding will be used to expand the engineering team, strengthen the sales function, and support further roll-outs across Ireland and the UK.
What's Next
The company plans to use the new capital to accelerate its expansion across dental practices in Ireland and the UK, with potential for further international growth thereafter. Read the full ThinkBusiness report here.
