A solo founder just proved Sam Altman right. Matthew Gallagher started a telehealth company called Medvi from his living room in Los Angeles with $20,000 and a stack of AI tools. Eighteen months later, that one-person billion dollar company is on track to hit $1.8 billion in annual revenue — with a grand total of two employees. His brother Elliot is the only hire.

Stop and think about that for a second. Hims & Hers, a direct competitor in the GLP-1 telehealth space, did $2.4 billion last year. They needed 2,442 employees to get there. Gallagher is running triple their profit margin with a team you could fit in a Honda Civic.

If you’re building a solo business and wondering whether AI can actually replace a team — not in theory, but in practice — this story answers that question. And the lessons apply whether you’re selling telehealth services or handmade candles. I’ve been running my own one-person export company for years, and what Gallagher did maps directly to principles I’ve learned the hard way.

This article breaks down exactly how he did it, the AI tools he used, and the 4 moves you can copy today.

How a $20K Bet Became a One-Person Billion Dollar Company

In September 2024, Gallagher had an idea. The GLP-1 weight-loss drug market was exploding. Ozempic and Wegovy were everywhere. But getting a prescription still felt like navigating a bureaucracy designed in 1997. He spotted the gap between massive consumer demand and outdated delivery infrastructure.

So he did something most people wouldn’t consider. Instead of raising money, hiring developers, and spending 18 months building a team, he opened ChatGPT and started building the platform himself. No coding background. No medical degree. Just a clear hypothesis and $20,000 in savings.

The timeline is almost absurd. Two months from concept to launch. He outsourced medical consultations to CareValidate and OpenLoop — licensed telehealth platforms that handle prescriptions and doctor oversight. Shipping went through third-party pharmacies. What remained was the technology layer connecting patients to treatment, and AI built all of it.

By the end of his first full year, Medvi had 250,000 paying customers and $401 million in revenue. Now, according to PYMNTS reporting, the company is tracking toward $1.8 billion in 2026 sales. That makes it the first credible one-person billion dollar company in modern business history.

And before you dismiss this as a tech bro getting lucky with a trending product — the profit margins tell a different story. Medvi posted a 16.2% net margin. That’s not luck. That’s operational efficiency baked into the business model from day one.

The Exact AI Stack That Replaced 200 Employees

What fascinates me about Gallagher’s approach isn’t just the revenue numbers. It’s the specific way he used AI tools — not as productivity boosters, but as full replacements for departments that don’t exist.

Here’s his actual tool breakdown, based on Inc’s reporting:

Notice what he didn’t do: he didn’t build his own AI models. He didn’t train custom systems. He used off-the-shelf tools that you and I can subscribe to this afternoon. The total cost of his AI tool stack is likely under $500 per month — a rounding error against $1.8 billion in revenue.

The coding is the part that surprises people most. Gallagher used three different AI coding assistants (ChatGPT, Claude, and Grok) to write the platform. When one model produced buggy output, he’d cross-reference with another. That redundancy approach turns out to be more effective than a single tool, because each model has different strengths.

For your own solo business, the lesson isn’t to copy his exact stack. It’s to recognize that AI tools have reached the point where assembling them replaces hiring. You’re not looking for an all-in-one solution. You’re building a solopreneur tech stack where each piece handles one function.

Why GLP-1 Telehealth Was the Perfect Solo Founder AI Business Niche

Not every market works for the one-person billion dollar company model. Gallagher picked his niche with precision, and understanding why helps you pick yours.

GLP-1 drugs had three things going for them in 2024-2026:

1. Massive, growing demand. The global weight-loss drug market hit $24 billion in 2024 and is projected to reach $150 billion by 2030, according to Goldman Sachs research. Patients were already searching for these drugs online in huge numbers.
2. High willingness to pay. Patients spend $300-$500 per month on GLP-1 medications. That’s recurring revenue with strong retention (people stay on these drugs for years).
3. The middleman was broken. Getting a GLP-1 prescription through traditional channels meant doctor visits, insurance battles, and pharmacy delays. Telehealth cut that process to minutes.

But here’s the part most people miss. Gallagher didn’t need to handle the regulated parts himself. Medical consultations? Outsourced. Prescriptions? Outsourced. Pharmacy fulfillment? Outsourced. He built the technology layer — the website, the user experience, the marketing — and connected existing services together.

This pattern works beyond telehealth. If you’re building a solo business, look for markets where demand exceeds supply AND where the delivery chain can be outsourced. You become the connector, not the provider. AI handles the technology, partners handle the operations, and you handle the strategy.

I wrote about similar approaches in my piece on profitable AI automation business models. The common thread? Solo founders who succeed in 2026 aren’t doing everything — they’re orchestrating everything.

Medvi vs. Hims: When 2 People Outperform 2,400

The comparison between Medvi and Hims & Hers tells you everything about where business is headed. And honestly, the numbers are a little embarrassing for the traditional model.

Hims & Hers is a publicly traded company. They reported $2.4 billion in 2025 revenue with 2,442 full-time employees. Their net profit margin? Just 5.5%. That’s after years of optimization, public market pressure, and a massive operational infrastructure.

Medvi, meanwhile, posted $401 million in its first year with a 16.2% net margin. Two employees. Nearly three times the profit efficiency, measured dollar-for-dollar.

Some quick math that should make every solopreneur pay attention:

• Hims revenue per employee: roughly $983,000
• Medvi revenue per employee: $200,500,000. Yes, two hundred million per person.
• Hims net profit per employee: about $54,000
• Medvi net profit per employee: over $32 million

Now — a fair critic would point out that Medvi outsources functions that Hims keeps in-house. That’s true. But that’s precisely the point. The one-person billion dollar company model doesn’t mean doing everything yourself. It means owning the parts that matter and letting AI plus outsourcing handle the rest.

For you, this comparison should reshape how you think about scaling. Adding employees isn’t the only growth path. Sometimes it’s not even the best one. If you can replace a $150K/year hire with $200/month in AI tools and a service partnership, your margins don’t just improve — they multiply.

4 Tactical Moves You Can Steal From Gallagher’s Playbook

You’re probably not going to build a billion-dollar telehealth startup tomorrow. Neither am I. But Gallagher’s specific tactics translate to solo businesses at every scale.

1. Use Multiple AI Models, Not Just One

Gallagher bounced between ChatGPT, Claude, and Grok when writing code. This isn’t about brand loyalty — it’s about getting better output. Each model handles different tasks differently. Claude tends to write cleaner, more structured code. ChatGPT excels at brainstorming solutions. Grok (built on xAI) offers a different perspective on edge cases.

Apply this to your business. Don’t marry one AI tool. Use the right model for each job. I use this exact approach when creating content and automating workflows in my export business.

2. Outsource Everything That Isn’t Your Core Advantage

Gallagher’s core advantage was speed and technology. So he outsourced medical operations, pharmacy, and fulfillment. He kept control of the customer experience and the code.

Ask yourself: what part of your business would disappear if you stopped doing it personally? That’s your core. Everything else is a candidate for outsourcing or AI replacement. Check out how AI agents can handle solo business operations for practical examples.

3. Move Fast and Fix Later

Two months from idea to launch. That timeline would terrify a traditional startup founder worried about perfection. But in a market with explosive demand, being first matters more than being polished. Gallagher launched, got customers, and improved the platform while revenue was already flowing.

For solo founders, this means shipping your MVP before it feels ready. Your first 100 customers will tell you what’s broken faster than six months of internal testing.

4. Pick Markets Where Speed Beats Capital

Gallagher didn’t raise venture capital. He didn’t need to, because his market rewarded speed over scale. The GLP-1 demand curve was so steep that a fast, competent product beat a slow, well-funded one.

When you’re choosing your next business idea, look for markets where customer demand is growing faster than supply. Where the friction in the buying process is the main bottleneck — not the product itself. Those are the markets where a solo founder with AI tools can genuinely compete with funded companies.

What My Solo Export Business Taught Me About These Principles

I’ve been running a solo cosmetics export business for years now, shipping products to over 15 countries. And reading about Gallagher’s story felt like looking into a mirror — or maybe a crystal ball.

Back in 2021, I was drowning in operational tasks. Customs paperwork, supplier negotiations, customer emails in four languages, shipping logistics. I hired freelancers for some of it, but managing freelancers became its own full-time job.

When I started replacing those processes with AI tools in 2024, my operating costs dropped by about 40%. Not overnight — it took me six months of testing and failing to find the right setup. I tried three different AI translation tools before finding one that handled Korean-to-Arabic business correspondence without embarrassing mistakes. My first attempt at automating customs documentation produced forms that would’ve gotten my shipments seized at the border. Painful lessons.

But here’s what I share with Gallagher, even at a fraction of his scale: the principle that a solo operator plus the right AI tools can match — and sometimes beat — what used to require a full team. My export margins improved from 12% to nearly 22% after implementing AI across customer service, translation, and documentation. Not billion-dollar numbers, but the same pattern.

The biggest lesson? You don’t need permission, venture capital, or a co-founder to build something that works. You need a clear market, the willingness to experiment with AI tools, and the patience to fix things when they break.

Frequently Asked Questions

Is Medvi really run by one person?

Medvi currently has two employees: founder Matthew Gallagher and his brother Elliot. All engineering, marketing creative, and customer service functions are handled by AI tools, while medical operations are outsourced to licensed telehealth partners CareValidate and OpenLoop.

What AI tools did Matthew Gallagher use to build Medvi?

Gallagher used ChatGPT, Claude, and Grok for writing the platform’s code. Midjourney and Runway generated marketing images and video ads. ElevenLabs and custom AI agents manage customer service interactions. The total AI tool cost is estimated at under $500 per month.

Can I build a one-person billion dollar company in a different industry?

The billion-dollar outcome requires exceptional market conditions (massive demand, high margins, scalable delivery). But the model works at smaller scales across many industries. Solo founders using AI tools reported an average 340% revenue increase in 2026, according to recent survey data. Focus on markets where speed beats capital and distribution can be outsourced.

How much money do I need to start a solo AI business?

Gallagher started with $20,000, but many solo AI-powered businesses launch for under $5,000. Your main costs are AI tool subscriptions ($100-$300/month), domain and hosting ($20-$50/month), and initial marketing. The barrier isn’t capital — it’s finding the right market and executing quickly.

What Comes After the First One-Person Billion Dollar Company

Gallagher’s story isn’t a fluke. It’s a signal. The tools that made Medvi possible are available to every solo founder reading this right now, and they’re getting cheaper and better every month.

But here’s my honest take: most people won’t do what Gallagher did. Not because the tools are hard to use, but because they’ll wait for the perfect idea, the perfect stack, or the perfect moment. Gallagher’s real edge wasn’t AI — it was the willingness to start with $20K and figure it out along the way.

So here’s my challenge to you: pick one process in your business that still requires manual work, and replace it with an AI tool this week. Not next month. This week. That single step puts you closer to the one-person company model than 99% of founders who are still just reading about it.
