How a Solo Founder Built a SaaS by Selling to Veterinarians

**Fexingo** (0:01)
So, there's this idea that to build a successful SaaS company, you need to be a technical founder or have a technical co-founder. But there's another path that doesn't get enough attention.

**SPEAKER_2** (0:12)
Which is what? Just knowing the industry you're selling to inside and out.

**Fexingo** (0:17)
Exactly. And today's story is about Sarah Chen. She's a veterinarian, not a developer, not a product manager.
She built VetFlow, a SaaS platform for veterinary clinics, and it's doing over $1.2 million in annual recurring revenue.

**SPEAKER_2** (0:35)
Wait.
She's a practicing vet who built a SaaS product on the side? That's intense.

**Fexingo** (0:42)
She still sees patients two days a week. But the key insight here is how she got started. She didn't write code. She didn't hire a developer.
She went and sold the product before it existed.

**SPEAKER_2** (0:56)
So she did presales. We've talked about that before, but usually with founders who have some technical background. How did she pull it off without even a prototype?

**Fexingo** (1:06)
She had something more valuable, a real pain point she experienced every day.
Veterinary clinics in the US are overwhelmingly small businesses. About 85% are independently owned. They use POS systems designed for retail, not for pet medical records. So Sarah saw an opportunity to build something specific to vet workflows.

**SPEAKER_2** (1:29)
Okay, but selling software to small business owners is notoriously hard. They're busy, they're skeptical, and they've been burned by bad tech before.

**Fexingo** (1:38)
Right. So instead of cold calling or running ads, she used her network.
She's been a vet for 12 years, active in state veterinary associations, and she knew exactly which clinics were run by early adopters. She approached 50 clinics personally during her lunch breaks after shifts at conferences.

**SPEAKER_2** (1:58)
And they just handed over money for vaporware?

**Fexingo** (2:02)
No, she was very transparent. She said, I'm building something to fix the charting and billing mess we all deal with. It doesn't exist yet, but if you commit to $300 per month starting in six months, I'll give you a lifetime discount, 50% off, and you'll help shape the product.
She got 15 commitments in the first month.

**SPEAKER_2** (2:24)
15 clinics at $300 a month, that's $5,400 in committed monthly recurring revenue before a line of code. That's a pretty good validation signal.

**Fexingo** (2:35)
It also gave her the confidence to invest her own savings.
She hired a freelance developer from Upwork, a generalist in the Philippines, and built the first version in about four months. The MVP was basically a glorified spreadsheet with a booking system.

**SPEAKER_2** (2:51)
And those first 15 clinics actually used it? I feel like a lot of pre-sales fall through when the product is late or doesn't deliver.

**Fexingo** (3:00)
12 of the 15 stayed on. The other three said it wasn't ready yet, but they were polite. Sarah's advantage was that she kept those clinics involved in the development.
She set up a private Facebook group where they could request features and report bugs. So they felt ownership.

**SPEAKER_2** (3:18)
That's smart. It's basically continuous customer development built into the process, and it probably helped with retention too.

**Fexingo** (3:27)
Huge. Her churn rate is around 3% annually, which is absurdly low for B2B SaaS.
The average for small business software is closer to 5-7% monthly. She's basically built a product that vets can't afford to leave because it's tailored specifically to how they work.

**SPEAKER_2** (3:46)
Let's talk about pricing.
$300 per clinic per month, that's not cheap for a small business. How did she justify it?

**Fexingo** (3:54)
She framed it as a cost saver, not an expense. The average veterinary clinic in the US loses about $4,000 per month due to billing errors, missed appointments, and inefficient charting.
VetFlow automates a lot of that. So the ROI calculation was straightforward, $3,600 a year in software cost versus $48,000 in potential savings.

**SPEAKER_2** (4:18)
That math works. And she could point to specific case studies from those first 12 clinics to prove it.

**Fexingo** (4:25)
Right. And this is where the domain expertise really pays off. Sarah knew exactly which metrics to track because she lived them. Her sales pitch didn't sound like a generic software demo.
It sounded like a fellow vet recommending a better way to run a practice.

**SPEAKER_2** (4:42)
It makes me think about how many other industries have frustrated professionals who could build a SaaS product if they understood the playbook. There's a huge opportunity for non-technical founders who are willing to learn the basics of product development.

**Fexingo** (4:56)
If these conversations are useful for what you're building or running, I want to mention something. We deliberately don't run ads on this show.
