30 Boring Businesses That Quietly Make Millions (And How People Actually Started Them)
When I first started researching boring businesses, I assumed they were tiny side hustles. The reality was very different.
Many of these companies generate six-figure or seven-figure revenue every year.
And what surprised me most was that many of them were started by ordinary people with no special background often times started as a side hustle.
First, what is a boring business? A boring business is generally a service business and offers core, repeatable services that a customer would often need. Think of things like laundry, cleaning, cooking, car wash, etc.
Boring businesses are great because they are often overlooked as more exciting businesses involving tech and AI often get the limelight. But that doesn’t mean they are unprofitable, as so many entrepreneurs prove in this article.
Let’s look at how some of these businesses actually work — and how real entrepreneurs built them.
1. Laundromats
If you walk into a laundromat, it doesn’t look like a goldmine. It’s usually just rows of washing machines and dryers.
But laundromats are one of the most reliable boring businesses in the world because laundry is something people simply can’t avoid. Apartments, students, and travelers constantly need places to wash clothes.
On average, laundromats can generate around $300,000 in annual revenue, with relatively low failure rates compared to restaurants or retail businesses.
I remember reading about a digital marketer named Jono Santamaria who bought a struggling laundromat in Australia. Instead of reinventing the industry, he simply modernized the business.
He upgraded the machines, improved branding, and started marketing the business online.
Within a year, he doubled the previous owner’s revenue, turning the laundromat into a profitable operation generating over $112,000 per year.
Starting a laundromat typically involves three steps.
First, you either purchase an existing laundromat or lease a location in an area with many renters. Then you install commercial washers and dryers, which are the main upfront investment. Finally, you focus on operational improvements like payment systems, security cameras, and extra services such as wash-and-fold or laundry pickup.
Many successful owners eventually scale by opening multiple locations because the business model is highly repeatable.

2. Self-Storage Facilities
Self-storage might be one of the most underrated business models ever created.
Think about it for a moment. People rent storage units when they move, downsize, travel, or simply run out of space at home. Once their belongings are stored somewhere, they often keep paying for months or even years.
The self-storage industry generates tens of billions in annual revenue, with average occupancy rates around 92%, making it one of the most stable real estate businesses.
The way people start storage businesses varies.
Some entrepreneurs purchase existing storage facilities that are underperforming and increase revenue by improving marketing or raising prices slightly. Others build facilities from scratch in growing suburbs where demand is high.
The operational side is surprisingly simple. Most facilities are largely automated with gate access codes, security cameras, and online billing systems.
Once the system is set up, one manager can often operate hundreds of units.
3. Car Washes
Car washes are another classic boring business.
The beauty of this model is simple: cars get dirty constantly.
According to industry data, an automated car wash can generate around $139,000 per year, while large conveyor washes can earn over $700,000 annually.
One of the most interesting examples is John D’Eri, who co-founded a car wash called Rising Tide Car Wash.
What made the business unique wasn’t the service — it was the mission. The company focuses on employing people with autism, creating a strong community reputation.
The result?
The business grew into a multi-million-dollar operation generating around $6 million annually.
Starting a car wash typically requires a larger upfront investment because of equipment and land costs. However, many entrepreneurs reduce this barrier by purchasing existing car washes rather than building new ones.
Once operational, the model is relatively straightforward: customers pay per wash or sign up for monthly memberships.
Those memberships often become the real profit engine.
4. Vending Machine Routes
A vending machine business might sound too simple to be profitable.
But the power of vending machines comes from scale.
Each machine produces small amounts of income. When you operate dozens or hundreds of machines, those profits add up quickly.
Adam Hill reportedly built a vending machine route generating $1.2 million annually while working only a couple days per week.
Most vending entrepreneurs start by buying a few used machines and placing them in locations with heavy foot traffic like offices, gyms, schools, or apartment buildings.
The key skill is negotiating placement deals with property owners. Once the machines are installed, the job mainly involves restocking products and collecting revenue.
5. Pressure Washing Businesses
Pressure washing is one of the easiest boring businesses to start.
You can launch the business with relatively inexpensive equipment and begin offering services to homeowners or small businesses.
One entrepreneur shared that he started pressure washing part-time on weekends and generated about $65,000 in his first year, later growing toward a six-figure business.
The business works because buildings, driveways, and sidewalks constantly collect dirt, mold, and debris.
Property owners often prefer to hire professionals rather than buy equipment themselves.
Many pressure washing companies start with residential work but eventually move into commercial contracts, which are far more lucrative and stable.

6. Cleaning Companies
Cleaning services are another industry most people overlook.
Yet businesses, offices, schools, and hotels all require regular cleaning.
One entrepreneur named Conan Sammon started by cleaning wheelie bins for neighbors for just £2 each. Over time he expanded into commercial cleaning services and built a company generating £1.5 million in annual turnover with dozens of employees.
Cleaning businesses are relatively simple to start.
Most entrepreneurs begin by offering residential cleaning services to local homeowners. As the client base grows, they expand into commercial contracts where companies pay monthly service fees.
Those long-term contracts are what transform small cleaning companies into scalable businesses.

7. Lawn Care and Landscaping
Lawn care is a perfect example of recurring demand.
Grass doesn’t stop growing, which means homeowners and businesses need regular maintenance.
Many landscaping companies start with basic mowing services and gradually expand into higher-value work like irrigation systems, garden design, and seasonal services such as snow removal.
The result is a business with predictable weekly revenue during peak seasons.
8. Pool Cleaning Businesses
In warm climates, pool cleaning is an extremely consistent business.
Most pool service companies charge monthly service packages that include chemical balancing, cleaning, and maintenance.
Once homeowners find a reliable technician, they tend to stay with that company for years.
That makes it a subscription-style business with steady income.
9. Dumpster Rental Businesses
Dumpster rental businesses serve construction companies, contractors, and homeowners doing renovations.
The business model is simple.
You purchase a few dumpsters and a truck capable of delivering them. Customers rent the dumpster for a set period, then you collect it and dispose of the waste.
The profitability comes from the fact that each dumpster can be rented repeatedly.
Over time, operators expand their fleet and serve larger construction clients.
10. Property Management Companies
Property management companies handle tasks like tenant communication, maintenance coordination, and rent collection.
Instead of owning the property themselves, managers earn a percentage of the monthly rent.
Because the service is ongoing, property managers build steady monthly revenue as they add more units to their portfolio.
Many property management companies start by managing just a few properties for local landlords before expanding into large apartment complexes.
11. ATM Machine Businesses
One of the first boring businesses I discovered that really surprised me was the ATM machine business.
At first, it sounds almost too simple. You place an ATM in a location like a bar, convenience store, or nightclub, and every time someone withdraws cash, they pay a small transaction fee.
But those fees add up quickly.
I read about entrepreneurs who started with just one machine and eventually built entire ATM networks. Some operators reportedly earn between $300 and $3,000 per month per machine depending on the location.
The interesting thing is that the business isn’t really about the machines themselves — it’s about finding good locations. High-traffic spots like bars, casinos, and entertainment venues can generate thousands of withdrawals every month.
Starting an ATM business typically involves purchasing a machine, negotiating placement with a business owner, and sharing a portion of the transaction fees with that location.
Once installed, the business becomes fairly passive aside from refilling the cash.
12. Mobile Car Detailing
Another boring business that quietly produces strong income is mobile car detailing.
Unlike a traditional car wash, detailing focuses on deep cleaning both the interior and exterior of vehicles. Many customers are willing to pay premium prices because they want their cars restored to near-new condition.
I once read about an entrepreneur who started detailing cars out of the back of his SUV with basic equipment. Within a few years, he grew the business into a multi-vehicle operation servicing luxury dealerships and private clients.
Some detailers charge $150 to $400 per car, especially for premium services like paint correction or ceramic coatings.
Starting the business is fairly straightforward. Most operators begin with cleaning supplies, a pressure washer, and a reliable vehicle. Then they market services locally through social media, Google listings, and partnerships with dealerships.
Once demand grows, they hire additional technicians and expand into a full detailing company.
13. Portable Toilet Rental
Portable toilet rental might be one of the least glamorous businesses imaginable.
But it’s also one of the most dependable.
Construction sites, outdoor festivals, sporting events, and large gatherings all require portable restrooms.
Because these units must be regularly serviced and cleaned, customers typically rent them for extended periods.
Entrepreneurs in this space generate revenue from both rental fees and servicing contracts, which means the same unit can generate income for years.
Daniel Tom makes $4.3 million per year from his Porta Potty business, Bay Area Sanitation and has a fleet of almost 2,000 portable toilets!
Starting the business requires purchasing a few units and a truck capable of transporting and servicing them. Many companies begin with just a handful of toilets and gradually expand their fleet as they secure contracts with construction companies and event organizers.
14. Parking Lot Striping
Parking lot striping is another business most people never think about — until the lines fade.
Businesses, shopping centers, schools, and hospitals are required to maintain clearly visible parking lines and accessibility markings.
That’s where striping companies come in.
The startup cost is relatively low compared to many service businesses. You typically need a striping machine, paint, and a truck or trailer.
One entrepreneur I read about began by offering striping services to small retail plazas and eventually built a regional company serving large commercial properties.
Because parking lots require repainting every few years, customers often return repeatedly.
15. Chimney Cleaning
Chimney cleaning might sound old-fashioned, but it’s still a necessary service in many regions.
Homes with fireplaces need annual inspections and cleanings to prevent dangerous creosote buildup, which can cause chimney fires.
Many chimney sweeps operate small family businesses that serve hundreds of households each year.
A typical cleaning service can cost $150 to $400, and technicians often perform several appointments per day during peak winter seasons.
Entrepreneurs entering this business usually start by completing certification training and investing in specialized cleaning equipment.
Because safety is involved, customers often prefer experienced professionals, which means strong reputation and referrals can quickly build a loyal customer base.
16. Fence Installation
Fence installation is another surprisingly profitable boring business.
Homeowners install fences for privacy, security, pets, and property boundaries. Developers also need fencing for new housing projects.
The work can be physically demanding, but the financial rewards can be significant.
Fence installation jobs can range from $1,500 to $10,000 or more, depending on materials and property size.
Many fence companies begin with small residential projects and gradually expand into commercial work.
Once a company builds a reputation locally, referrals become a major source of new customers.
17. Gutter Cleaning
Gutter cleaning is one of those services homeowners rarely think about — until their gutters clog and cause water damage.
Because the job can be messy and sometimes dangerous, many homeowners prefer to hire professionals.
Some entrepreneurs have turned gutter cleaning into surprisingly profitable seasonal businesses.
One entrepreneur reportedly built a local gutter cleaning company generating six-figure revenue annually, primarily through repeat customers and neighborhood marketing.
Starting the business requires basic ladders, safety equipment, and cleaning tools. From there, many companies expand into related services like roof cleaning and gutter installation.
18. Window Cleaning
Window cleaning might be one of the simplest businesses to start, but it can grow into a very scalable company.
Residential homeowners hire window cleaners a few times per year, while commercial buildings often require regular cleaning schedules.
Some commercial contracts involve cleaning large office buildings every month.
Entrepreneurs often begin by offering services to homeowners in their local neighborhoods. Over time, they expand into larger commercial contracts, which can generate stable recurring income.
19. Tree Removal Services
Tree removal is another industry where demand never seems to disappear.
Storm damage, safety concerns, and landscaping projects all create constant demand for tree services.
Although the startup costs are higher due to equipment and insurance requirements, the job payouts can be substantial.
Individual tree removal jobs can range from $500 to several thousand dollars, depending on size and difficulty.
Many companies begin by offering trimming and small removal jobs before expanding into larger projects with specialized equipment.
20. Moving and Junk Removal
Moving and junk removal services are two businesses that often overlap.
People constantly need help moving houses, clearing out garages, or removing unwanted furniture.
One well-known example is College Hunks Hauling Junk, which started as a small moving business run by two college friends. The company eventually grew into a national franchise with hundreds of locations and millions in annual revenue.
The business is straightforward to start.
Most entrepreneurs begin with a truck, a few workers, and basic marketing. As the company grows, they add additional trucks and expand into both residential and commercial contracts.
21. Septic Tank Pumping
Septic tank services might be one of the least glamorous businesses imaginable.
But if you live in a rural or suburban area, septic systems require regular pumping and maintenance. Homeowners typically need their tanks pumped every three to five years, which creates steady demand.
The way most septic businesses start is fairly straightforward. An owner purchases a specialized pumping truck and begins offering services to local homeowners. Over time, many companies expand into inspections, repairs, and septic system installations.
What makes this business so profitable is that once customers trust a company with their system, they tend to call the same provider every time.
22. Fire Extinguisher Inspection Services
This is one of those businesses I had never thought about before researching boring industries.
Every commercial building is legally required to maintain fire extinguishers and have them inspected regularly.
That means offices, restaurants, warehouses, and apartment buildings all need annual inspections.
Entrepreneurs in this space typically become certified technicians and offer inspection services to local businesses. Many charge service fees for inspections, refilling extinguishers, and replacing outdated equipment.
Because inspections must be done regularly, customers often stay with the same company year after year.
23. Ice Vending Machines
Ice vending machines are a fascinating business model.
They’re basically giant automated kiosks that sell bags of ice directly to customers 24/7.
Instead of running a convenience store, owners simply install the machine in a high-traffic location like a gas station or marina.
Customers drive up, pay at the machine, and collect their ice.
The startup cost can be significant, but once installed, the machines require minimal labor. Operators typically earn revenue from every bag sold, and demand spikes during summer months.
24. Document Shredding Services
Businesses generate huge amounts of sensitive paperwork.
Things like financial records, medical documents, and legal files must be destroyed securely to prevent identity theft or data leaks.
That’s where document shredding companies come in.
Many operate trucks equipped with industrial shredders that visit businesses on scheduled routes. Companies pay monthly service fees to have their confidential documents destroyed.
Entrepreneurs often begin with a single shredding truck and expand their routes as they gain clients.
25. Parking Garage Management
Parking garages might look like simple real estate, but managing them can be a lucrative business.
Many property owners outsource parking management to companies that handle payment systems, maintenance, and staffing.
Some entrepreneurs specialize in managing multiple garages across a city, collecting management fees from each property.
Others purchase small parking lots themselves and generate revenue through hourly or monthly parking fees.
In dense urban areas, parking can be an extremely valuable commodity.
26. Portable Storage Container Rentals
Portable storage containers are those metal boxes you often see sitting in driveways during home renovations or moves.
Companies deliver the container to a customer’s home, the customer fills it with belongings, and the company picks it up and stores it or moves it to a new location.
Businesses like PODS have built entire national companies around this idea.
Smaller operators can start locally with a handful of containers and a truck capable of transporting them.
Demand comes from people moving houses, renovating properties, or temporarily storing belongings.
27. Asphalt Sealcoating
Parking lots and driveways deteriorate over time.
To extend their lifespan, property owners apply sealcoating — a protective layer that prevents cracks and weather damage.
Sealcoating companies specialize in applying this protective coating to commercial parking lots and residential driveways.
Many entrepreneurs start by offering services to small local businesses and gradually expand into larger commercial contracts.
Because asphalt needs resealing every few years, customers often become repeat clients.
28. Boat Cleaning and Maintenance
In coastal or lakefront areas, boat cleaning is a surprisingly profitable niche.
Boat owners often prefer to hire professionals to clean and maintain their vessels because the process can be time-consuming and physically demanding.
Services often include washing, polishing, and interior cleaning.
Entrepreneurs usually start by partnering with marinas and offering services to boat owners who keep their vessels docked there. Natalie Sears started here boat detailing business and it has gone from strength to strength. She started almost three decades ago as well!
29. Sign Installation
Businesses constantly install new signage for storefronts, offices, and commercial buildings.
But the companies that design signs aren’t always the ones who install them.
That’s where sign installation businesses come in.
These companies handle mounting large signs on buildings, installing illuminated signs, and maintaining existing signage.
It’s a niche service that requires equipment like lifts and ladders, but once established, many installers secure contracts with sign manufacturers and marketing agencies.
30. Pet Waste Removal Services
This might be one of the most unusual boring businesses I’ve come across.
Pet waste removal companies literally clean up dog waste from residential yards.
Homeowners with busy schedules often pay monthly subscriptions to have their yards cleaned weekly.
While the job isn’t glamorous, the business model is surprisingly effective because customers typically subscribe for ongoing service.
Many entrepreneurs start this business with basic equipment and quickly grow their client base through local marketing and referrals.
Final Thoughts
When I first started learning about boring businesses, I assumed they were small operations.
But the more examples I studied, the more I realized that these businesses often produce consistent, predictable income for decades.
The reason is simple.
They solve everyday problems.
Laundry still needs washing.
Cars still get dirty.
Homes still need cleaning and repairs.
And while many entrepreneurs chase trendy startups, the people building these businesses are quietly creating stable companies and long-term wealth.
Sometimes the smartest opportunity isn’t the most exciting one.
Sometimes it’s simply the business that everyone else ignores.

The Real Secret Behind Boring Businesses
After studying all of these examples, I realized something important.
Most successful entrepreneurs aren’t chasing the newest idea.
They’re solving problems that already exist.
Laundry still needs washing.
Buildings still need cleaning.
Cars still get dirty.
And while these businesses might not look exciting on the surface, they often provide something far more valuable than flashy startups:
Predictable cash flow.
