How Did Two Brothers Build a $1.8 Billion Company With AI and $20,000? Here Is What Business Owners Need to Know.

In 2024, Sam Altman made a prediction on a podcast.

He said a one-person business worth a billion dollars "would have been unimaginable without A.I., and now it will happen."

Two years later, he emailed The New York Times to say he won the bet.

Who Are Matthew Gallagher and Medvi?

Matthew Gallagher is a 41-year-old entrepreneur from Los Angeles.

He is not a software engineer. He did not raise venture capital. He had no office and no team.

In late 2024, he spent $20,000 and two months building a telehealth company called Medvi from his living room. Medvi sells GLP-1 weight-loss medications online. In its first full year of operation, according to The New York Times, Medvi generated $401 million in revenue and $65 million in net profit.

That is a 16.2% profit margin.

For reference, that is nearly three times the net margin of Hims & Hers — a publicly traded company in the same space with 2,442 employees.

In 2026, Medvi is on track for $1.8 billion in sales.

Current headcount: two people. Matthew and his brother Elliot.

What AI Tools Did Matthew Actually Use?

This is where it gets practical.

Gallagher did not build AI. He assembled it.

He used over a dozen tools, and according to The Rundown AI's coverage of the story, his stack breaks down like this:

• ChatGPT, Claude, and Grok handled code and content. He used these to build the software that powers the company, write the website copy, and draft customer communications.
• Midjourney generated all the images for ads and the website.
• Runway produced video ads.
• ElevenLabs handled customer service calls with AI voice tools.
• Custom AI agents stitched the systems together and automated operational tasks.

He outsourced everything that required humans by regulation — the doctors, the prescriptions, the shipping — to two platforms: CareValidate and OpenLoop Health. They handle clinical compliance. He handles everything else.

The result is a business with almost no fixed overhead outside of software subscriptions and marketing.

Business Insider reported that Medvi now also contracts human professionals for legal and accounting work. But the core operations run on AI.

Gallagher is not the only one. Forbes covered three other founders who built companies on the same model: OpenClaw, Base44, and Daymaker. All are running lean, high-margin operations with tiny teams powered by AI.

This is not an outlier anymore. It is a pattern.

Introducing the AI Leverage Stack

Here is the framework I want you to take away from this story.

I call it the AI Leverage Stack.

Most business owners think about AI as a single tool. A chatbot. Something that writes their emails faster.

But what Gallagher built is different. He stacked five distinct layers of AI capability:

Layer 1: Build (ChatGPT, Claude, Grok) AI that writes your code, your copy, and your processes. This is the foundation. You use it to create the systems your business runs on.

Layer 2: Create (Midjourney, Runway) AI that produces your marketing assets. Images, videos, ads. No creative agency needed.

Layer 3: Communicate (ElevenLabs, custom chatbots) AI that handles your customer interactions. Calls, responses, follow-ups. At scale.

Layer 4: Analyze (custom AI agents) AI that watches your numbers and tells you what is working. Real-time performance analysis without a data team.

Layer 5: Connect (API integrations, workflow automation) AI that ties everything together. Custom agents that make your tools talk to each other.

When all five layers are running, you have a business that operates like a team of 50 people on the overhead of two.

That is the leverage. That is what Medvi proved.

What Does This Mean if You Are Not Building a $1.8 Billion Company?

Here is the truth: you do not need to be building a telehealth empire to use this.

The AI Leverage Stack applies to every business type in our audience. Coaches, consultants, product sellers, service businesses, real estate investors.

If you are a solo consultant billing 40 hours a week, adding a Layer 3 (AI communication) alone could let you take on twice the clients without working more hours.

If you run a product business, adding Layer 2 (AI creative) could cut your ad production costs by 70% and let you test more creative angles.

If you run a service team, Layer 4 (AI analysis) could surface the exact clients and services that drive your highest margins.

You do not need all five layers on day one. Most business owners should start with one.

Pick the layer that removes the biggest bottleneck in your business right now. Build from there.

What Is the Real Lesson From the Medvi Story?

A lot of people are reading this story wrong.

They see a $1.8 billion company with two employees and they think: "AI is going to replace everyone."

But that is not actually what happened.

Gallagher did not let AI run without direction. He made thousands of decisions about which tools to use, how to wire them together, which markets to enter, and when to outsource what he could not automate.

As one LinkedIn analyst put it: "AI doesn't replace the need for operational thinking. It raises the stakes."

The gap between someone who has access to AI and someone who gets results from AI is the same gap it has always been in business: execution.

Gallagher built an operational architecture. That is the skill. AI was the tool that made the architecture run with two people instead of two hundred.

This is a huge insight for business owners.

The businesses that win in the next five years will not be the ones with the most employees or the biggest budgets. They will be the ones with the best operating systems.

And AI, right now, makes it cheaper and faster to build those operating systems than at any point in history.

How Can You Start Building Your Own AI Leverage Stack?

Here are three concrete steps.

Step 1: Audit your most expensive repetitive tasks.

Write down the five things that take the most of your or your team's time each week. Not high-value strategy work. The repetitive stuff. Customer service responses. Content creation. Ad design. Report generation. Data entry.

These are your Layer 1 and Layer 3 candidates.

Step 2: Pick one layer and go deep for 30 days.

Do not try to automate everything at once. Gallagher did not launch with all five layers on day one. He built it over months, starting with the foundation.

Pick one tool. Use it every day. Get good at it before moving on.

Step 3: Measure what it frees up.

When you remove a task from your week using AI, track how many hours you recovered. Then use those hours on the highest-value thing only you can do: sales conversations, relationship building, product development, strategy.

That is how the stack compounds. Each freed hour redirects into revenue-generating activity.

What Mistakes Do Business Owners Make When They Try to Do This?

Three patterns come up over and over.

Mistake 1: Treating AI like a search engine.

Asking AI a question and reading the answer is not using AI. You need to give it tasks. Specific, detailed, operational tasks. The more context you give it, the better it performs. Gallagher built custom agents that had all of Medvi's business context built in. That is a different level of output than a generic ChatGPT prompt.

Mistake 2: Trying to automate everything at once.

When business owners see what is possible, they want to flip a switch and have all of it working tomorrow. That approach almost always fails. Complexity without mastery creates chaos. Start with one automation that actually runs. Then stack from there.

Mistake 3: Thinking the tools matter more than the strategy.

Gallagher used ChatGPT, Claude, Grok, Midjourney, Runway, and ElevenLabs. You can use those same tools today. They are not hard to access.

What you cannot copy by downloading an app is Gallagher's ability to spot a market, build an operational architecture around it, and execute relentlessly.

The tools are available to everyone. The discipline is not.

FAQ

Q: Did Matthew Gallagher really build Medvi with just two people? A: Yes. The New York Times profiled the company and confirmed the two-employee count. He now contracts human specialists for legal advice and accounting, and uses third-party telehealth platforms for clinical infrastructure, but the company's core operations run on AI. Matthew and his brother Elliot are the only full-time employees.

Q: What is the AI Leverage Stack and how do I use it? A: The AI Leverage Stack is a five-layer framework for replacing operational overhead with AI: Build (code and content AI), Create (image and video AI), Communicate (voice and chat AI), Analyze (data and performance AI), and Connect (workflow automation AI). You do not need all five layers at once. Start with the one that removes your biggest bottleneck, build competency there, then add the next layer.

Q: Can I replicate what Medvi did in my industry? A: The exact model depends on your business. Medvi worked because Gallagher outsourced regulated functions (medical compliance, prescriptions) to existing platforms and used AI to handle everything else. The principle applies anywhere: identify what in your business requires human compliance or relationship, outsource that, and automate the rest. The playbook scales across services, e-commerce, coaching, and consulting.

Q: What AI tools should I start with if I am a small business owner? A: Start with ChatGPT or Claude for your highest-volume writing tasks — customer emails, content drafts, process documentation. Once you have that running, add one creative tool (Midjourney for images, Runway for video). Then look at automating your customer follow-ups with a tool like ElevenLabs or a chatbot. Build the stack one layer at a time.

Q: Is Sam Altman's prediction about one-person billion-dollar companies really coming true? A: Yes. Forbes covered three additional founders who built companies on the same model in 2026: OpenClaw, Base44, and Daymaker. Altman emailed The New York Times to confirm he won a bet with tech CEO friends about when this would happen. The pattern is repeating.
