How a Solo Founder Built SaaS Selling to Dentists

**Lucas** (0:01)
So today we're talking about a vertical that I think is quietly one of the best bets for a first time solo founder, dental practices.

**Luna** (0:10)
Dentists? That feels very specific. What makes them different from, say, bakeries or dog daycares, which we've covered before?

**Lucas** (0:19)
Good question. The key difference is sticky recurring revenue.
Dental practices have incredibly low churn because switching software means retraining staff, potentially disrupting patient records, and dealing with insurance credentialing. Once a practice adopts a tool, they tend to stay for years.

**Luna** (0:38)
So the switching costs are high. That's built-in retention.

**Lucas** (0:42)
Exactly. But let me ground this in a real story. A founder I spoke with, let's call him Mike, started building a scheduling tool for dentists back in 2023 He had no dental industry experience.
He just noticed that every time he went to his own dentist, the front desk was wrestling with a paper calendar and an ancient desktop app.

**Luna** (1:04)
Classic pain point. Did he build a general scheduling tool first or go straight for dental?

**Lucas** (1:11)
He actually tried the general route. He built a simple online booking widget and tried to sell it to any small business. That went nowhere. Then a dentist friend told him, The Rayol pain isn't booking.
It's insurance verification and treatment plan presentation. That was his pivot moment.

**Luna** (1:30)
Insurance verification.
That's where the complexity lives. Every insurance plan has different coverage, co-pays, waiting periods. For a generalist tool, that's a nightmare. But for a dental specific one, it's a moat.

**Lucas** (1:46)
Exactly. Mike spent six months building a module that connects to the major dental practice management systems, like Dentrix and Eagle Soft, and Automate's eligibility checks. That solved a real back-end headache.
Within a year, he had 60 practices paying $500 a month.

**Luna** (2:05)
Wait, $500 a month for a single practice? That seems high for a solo operation.

**Lucas** (2:12)
It is, but remember, dental practices have high average revenue per patient. A single hygienist can generate $2,000 a day. If your software saves them just 30 minutes of insurance admin per day, that's easily worth $500.
And Mike's net dollar retention was around 120 percent. Existing customers upgraded as they added more providers.

**Luna** (2:37)
So, he's not just acquiring customers, he's expanding them. That's the dream metric for a SaaS business.

**Lucas** (2:45)
Right. And here's the stat that really sold me on this vertical.
There are roughly 13,000 solo dental practices in the US. That's a $78 million addressable market just at $500 per month. But most practices use two or three software tools, scheduling, billing, patient communication. So, you can expand into adjacent modules.

**Luna** (3:09)
13,000. That's a niche you can actually reach with direct sales.
No need for a massive marketing budget.

**Lucas** (3:17)
That's the thesis.
Mike cold emailed 200 dentists, got maybe 10 replies, but those 10 became his design partners. He charged them a discounted rate in exchange for feedback. That's how he validated the product without any funding.

**Luna** (3:33)
I love that approach. It's the opposite of the build it and they will come fantasy.

**Lucas** (3:39)
Yeah, and it's realistic. Look, if these conversations are useful for what you're building or running, consider supporting the show at buymeacoffee.com/fexingo.

And every bit of support goes right back into finding more founders to interview. We really appreciate it.

**Lucas** (4:01)
So back to Mike.
One challenge he hit was HIPAA compliance.
Dental software deals with protected health information, so he needed to encrypt data at rest and in transit sign business associate agreements and get annual audits. That scared off some competitors.

**Luna** (4:17)
But it also raised the barrier to entry. If you can handle HIPAA, you've got a defensible product.

**Lucas** (4:24)
Exactly. Mike used a compliance as a service platform to handle the paperwork.
Cost him about $200 a month. But the real work was building the product securely from the start. He wrote his own encryption layer and used a HIPAA-eligible cloud provider.

**Luna** (4:42)
That's a lot of overhead for a solo founder. How did he manage his time?

**Lucas** (4:47)
He was very disciplined. He blocked 9 a.m. to 1 p.m. for development, then 2 p.m. to 5 p.m. for sales calls.
He did his own support for the first 30 customers, which he says was the best way to find bugs and missing features.

**Luna** (5:04)
So, he was effectively running a one-person company, coding, selling, supporting. That's intense.

**Lucas** (5:11)
It was. But after 18 months, he hit $30,000 in monthly recurring revenue. That's when he hired his first employee, a customer success person, and his own role shifted more toward product and strategy.
