Why We Invested in Linda AI
If you’ve tried to book a dentist appointment lately, you’ve probably experienced being on hold. You call, it rings, maybe you get a busy signal, or you’re put on ice while the receptionist handles a patient standing right in front of them. It’s a bottleneck that frustrates patients and costs practices a fortune.
That’s why we’re excited to announce that earlier this year, we led the $2.5m Pre-Seed round in Linda AI. Here’s a look at why we decided to back them.
Linda isn’t just another chatbot, it’s a sophisticated AI voice agent designed specifically for the dental industry.
Linda AI is tackling the dental office’s biggest headache by building agentic workflows - essentially AI agents that don’t just suggest tasks, but actually finish them. They’ve built deep integrations into existing practice management systems so they can handle admin work end-to-end. Their wedge into the market is a voice-based AI receptionist that does it all: answering inbound calls, booking and rescheduling appointments, and even proactively hopping on outbound calls to re-engage patients who are due for a visit.
Beyond the Hype of AI Voice
We’ve all heard the buzz about AI agents, but the real winners won’t be the ones building general tools, they’ll be the ones solving massive and specific problems.
Our recent investment in Mindoo laid out our thesis for how we see the voice AI industry evolving. Backing Linda AI is the next logical step in our journey and a huge vote of confidence in where this technology is headed.
In the dental world, 70% of bookings still happen over the phone, yet a staggering 25% of calls go unanswered. That’s pure lost revenue. Between the missed bookings, the expensive no-shows, and a schedule full of gaps, it’s a massive financial leak that most practices just haven’t been able to plug - until now.
Linda steps in as an always-on digital receptionist that doesn’t just take messages, it actually acts. It understands context, navigates complex schedules, and integrates directly into a practice’s existing software to book, reschedule, and follow up with patients in real time.
Why Linda Wins: The Deep Integration Moat
As AI becomes more commoditised over time, we believe that the moat moves from the technology itself, to the speed of execution, as well as data and the workflow.
Linda has built a proprietary agentic operational layer on top of standard Electronic Health Records (EHR). This gives their agents practice-specific brains. Unlike superficial automation tools that just skim the surface, Linda gets smarter every day. By constantly capturing operational data to fine-tune workflows, Linda builds a competitive moat that basic bots just can’t touch.
The early stats are impressive. Within four months of launching and at the time of the investment, the platform had already been deployed in over 50 clinics across the UK and Ireland, handling more than 30,000 calls in the process. Today, Linda processes more than this on a weekly basis. Linda delivers a clear ROI for dental practices through both revenue uplift and cost savings: practices are seeing a 15% lift in bookings and a 30% drop in no-shows. Perhaps most impressive is the 98% positive patient feedback - it turns out people actually love it when the phone is answered immediately and the job gets done.
The Dream Team: Repeat Founders, Relentless Execution
At 6DC, we don’t just invest in tech, we invest in people. Linda is led by a trio of repeat founders who have built together before this (Xelda).
There’s a massive advantage in a team that already knows how to work together. They don’t have to ‘figure it out’, instead they just get to work, avoiding the typical potholes and executing at a pace that’s hard to keep up with.
From our very first meeting, we were blown away by the team’s energy and how clearly they saw the road ahead. But more than that, it was their raw execution speed that hooked us. We were impressed by how much product they’d already shipped, as well as the commercial traction they’d managed to pull off at such an early stage.
India Healy O’Connor (CEO): Ex-Goldman, economics powerhouse, and the engine behind their commercial GTM.
Portia Healy O’Connor (CPO): A management science expert (with a literal perfect academic score) who leads the product vision.
Lucio Tudisco (CTO): The technical backbone, formerly leading healthcare infrastructure at Amazon and engineering at Google and Reddit.
The Path Ahead: Tackling Dental Globally
The dental market is huge (over 500k practices across the UK, EU, and North America), but it’s also consolidating. Private equity groups are buying up practices and looking for ways to make them more efficient. Linda is a plug-and-play solution for these groups.
A key catalyst here is Linda's deep integrations with leading practice management systems, including Dentally. This deep technical integration has effectively turned on a lead-generation faucet for Linda. And because Linda is baked directly into the software dentists already use, the friction to join is almost zero.
However, inbound calls are just the beginning for Linda. It is already completing proactive work like patient recalls, appointment reminders and lead conversion and seeing impressive results with the largest DSOs in the industry. The long-term vision here is massive: turning the front desk from a chaotic bottleneck into a predictive, self-operating, revenue-generating system that runs in the background, enabling the clinical team to focus on patients.
