How a Solo Founder Built SaaS by Selling to Dental Labs

**Fexingo** (0:01)
So there's this solo founder, let's call him Dan, who built a SaaS product for Dental Laboratories. Now that might sound hyper-specific, but Dental Labs are actually a pretty interesting market. There are about 10,000 of them in the US alone, and most of them run on software that looks like it was built in the early 2000s.

What gave Dan the idea to focus on Dental Labs specifically? Was he in the industry?

**Fexingo** (0:27)
He wasn't. He was a software developer who happened to be dating a dental lab technician, and he'd hear her complain every night about the clunky case management system her lab used, losing orders, billing errors, just constant friction.
So he built a simple web app to handle order intake and invoicing for her lab.

**Luna** (0:46)
And then he realized other labs had the same problem.

**Fexingo** (0:50)
Exactly. His girlfriend's lab manager loved it, and within a week, three other labs in the same city asked if they could use it.
That's when Dan thought, okay, maybe this is more than a side project. And look, this actually ties in to something I want to mention. We deliberately don't run ads on these episodes. No sponsors, no commercials. It's a choice. If you find this kind of deep dive useful for what you're building or running, and you want to support that choice, the link is by me at coffee.com/fexingo.
Keeps things independent. Anyway, back to Dan, within six months, he had 10 labs paying $50 a month each.

**Luna** (1:30)
So $500 a month in recurring revenue. Not huge, but enough to validate the concept. How did he find those first 10 customers?

**Fexingo** (1:40)
He did something very old school, cold calling. He looked up dental labs on Google Maps, called the front desk, and asked for the lab manager or the owner. He'd say, I built a tool that helps labs cut down on order errors and get paid faster. Can I show you for 15 minutes?
He claims he got about a 20% conversion from demo to paying customer.

**Luna** (2:04)
That's actually pretty solid. Most B2B SaaS cold outreach sees single-digit conversion rates.

**Fexingo** (2:12)
Right. But Dan's product solved a very specific pain point. Labs lose money when orders get misrouted or invoicing is delayed. His software automated a lot of that.
So when he showed a demo, the value was immediately clear. By the end of year one, he had 50 labs, which is $2,500 a month.

**Luna** (2:33)
He was still solo at that point?

**Fexingo** (2:36)
Completely solo. He did the coding, the sales, the support. He told me he spent about 20 hours a week on customer emails alone. But the product was simple enough that support wasn't a huge drain.
It's not a complex CRM, it's order management and billing. He built it in Ruby on Rails, hosted on a cheap VPS, and his only recurring cost was about $50 a month.

**Luna** (3:01)
So he was running at something like a 98% margin on that $2,500 a month. That's a nice side income.

**Fexingo** (3:09)
Yeah, but he also had a full-time job. He didn't quit until he hit 200 labs, which took him about two years.
At that point, he was at $10,000 a month in revenue, and he felt comfortable going full-time. And here's the interesting part, he never raised any money.

**Luna** (3:33)
That's refreshing.
So how did he grow from 50 to 200 labs? Cold calling alone seems like it would scale poorly.

**Fexingo** (3:42)
He shifted to a referral program. Dental labs talk to each other, they're part of regional networks and industry associations.
Dan offered existing customers one month free for every new lab they referred that converted. That turned his customers into a sales force. About 60% of his new signups in year two came from referrals.

**Luna** (4:04)
So the product itself was sticky enough that people were willing to recommend it. What was his churn rate?

**Fexingo** (4:11)
Surprisingly low, around 3% monthly.
He said the main reason labs left was if they closed down or got acquired by a larger practice that used different software. The switching cost is moderate because labs have to retrain staff and migrate order histories. So once they're in, they tend to stay.

**Luna** (4:30)
What about pricing? Did he ever change it?

**Fexingo** (4:33)
He started at $50 a month for up to three users, then added a $75 tier for unlimited users.
Most labs chose the higher tier.
He also introduced a one-time setup fee of $200, which he said helped filter out tire kickers. By year three, he was averaging about $65 per lab per month.
