The $310K Letter Business You've Never Heard Of

From The Koerner Office Podcast Research

Most people think the mail is dead.

They're wrong.

Two Mormon entrepreneurs in Utah just proved it. They're making $310,000 per month sending handwritten letters to people. Not bills. Not junk mail. Love letters.

Here's how it works.

The Flower Letters Empire

The Clarks launched flowerletters.com in August 2020. Started with 38 subscribers. Now they have 31,000 people paying $10 per month.

Do the math. That's over $3.7 million per year.

What do customers get? Two letters per month that tell ongoing stories. Think romance novels delivered through your mailbox. World War II love stories. Historical fiction. Each series runs for months.

The genius part? People can't cancel mid-story. They need to know how it ends. Churn is nearly zero.

Their cost of goods? Less than $2 per customer per month. Stamps, paper, printing. That's it.

No paid ads. Pure word of mouth.

And they're using the biggest marketing subsidy nobody talks about - the US Postal Service. The true cost of delivering these letters is way more than what they pay for postage. American taxpayers are subsidizing their distribution.

The Hot Tub Gold Rush

While everyone's building apps, two teenage sisters in Idaho found something better.

They pull up to Airbnbs in a white van. Service hot tubs. Five minutes per property. $50-100 per week per hot tub.

They do 25 hot tubs per day.

In the middle of nowhere, Idaho.

The math is insane. Let's say average $75 per service. That's $1,875 per day. Over $450,000 per year for a van and two part-time workers.

But here's what's really smart - they also move hot tubs for retail stores. The stores don't want to deal with logistics. These kids became the delivery arm for multiple businesses.

One service. Multiple revenue streams.

The Monopoly You Can Still Buy

Island Park, Idaho. Population 236.

In summer and winter, it explodes with tourists. One hotel on the river rents inner tubes for $95. Three hours only. Those same tubes cost $15 on Amazon.

Why can they charge this? Location monopoly.

There's one rental place. It's right on the river. Customers have no choice.

Want to see legal monopoly pricing? A single kayak rents for $130. For three hours.

These businesses print money because they can't be disrupted. You can't build another river. You can't move the location.

The lesson? Find vacation destinations with limited competition. Buy the business with the best location. Charge premium prices.

The SaaS Nobody's Building

Here's a gap in the market.

You know how Enterprise and Hertz let you skip the counter? Just walk to your car and drive away? That same system needs to exist for boat rentals, ATV rentals, paddle board rentals.

Every vacation rental business still makes you:

• Sign waivers in person

• Get a 30-minute tutorial

• Wait in line to check equipment

Build the software that lets people do this online before they arrive. Sell it to rental companies as SaaS.

The framework works anywhere there's vacation rentals and long check-in processes.

The Directory Play That Actually Makes Money

Most directories make pennies from banner ads. Here's a better way.

Build a directory of businesses in your niche. Let's say autism clinics. List every ABA therapy center in the country.

Then email each clinic: "Hey, you're on my directory. Want to rank higher? Let me know."

Get them engaged with your platform. Then pitch your real service - digital marketing for their clinic.

The directory isn't the business. It's lead generation for your agency.

One guy is doing this right now. He gets 90% of his agency leads from the directory he built.

The Airbnb Concierge Nobody's Started

Rich people hate prep work.

Your brother-in-law has a lake house. Before every trip, someone has to:

• Gas up the boats

• Stock the fridge

• Clean the deck

• Prep the bedrooms

He'd pay $1,000+ to skip this. So would every other lake house owner.

The business model is simple. Text before you arrive. We handle everything. Show up and enjoy.

Market to lake house owners with flyers. They'll see them eventually when they come up to the property.

The AI Story Business for Kids

Remember getting mail as a kid? That feeling is gone for most children today.

Here's how to bring it back and make money.

Send kids personalized story letters. But make it interactive. The kid reads about themselves as the main character. At the end, they choose what happens next.

They mail back their choice. AI generates the next chapter based on their decision. Feels personal but runs on automation.

At the end of the full story? Offer to print it as a custom book. That's your upsell.

The Wedding Niche Directory

Everyone knows The Knot and Zola. They handle mainstream wedding services.

But what about the weird stuff? The beer burro that walks around with drinks on its back. The 360-degree photo booths. The vintage camper rentals. The fake tattoo bars.

Couples want Instagram-worthy weddings. They need unique services. But there's no directory for the weird wedding stuff.

Build it. Start in one city. List every off-the-wall wedding service. Give them free marketing. Then charge for premium placement once you have traffic.

The Real Pattern Here

Notice what these businesses have in common?

They're all taking something digital and making it physical. Or finding physical businesses everyone ignores.

While everyone builds apps, these people built real-world monopolies. Location advantages. Physical experiences AI can't replace.

The internet taught us everything should be instant and digital.

These businesses bet the opposite. Slow. Physical. Human.

And they're getting rich while everyone else fights over the same digital scraps.
