The Indoor Golf Franchise Boom Is Heading for a Reckoning
The indoor golf franchise market is growing at a pace that looks unsustainable if you stare at the numbers long enough.
Back Nine Golf has about 150 locations and is opening 20 new ones per month. That’s one every 36 hours. They’re selling franchises in Australia, Canada, and the UK now.
Five Iron Golf, the premium “eatertainment” concept backed by Danny Meyer’s Enlightened Hospitality, reports average unit volumes of $2.7 million per location. They grew from 22 outlets in 2023 to 37 in 2025, a 68% increase in two years. A franchisee signed a 12-unit deal just for Florida.
Another Nine, the Cincinnati-based 24/7 unmanned concept, has 75+ territories sold and opened its first franchised location in North Carolina in 2026. They raised $2 million and are accelerating.
TeeGo in the UK just secured a seven-figure investment from Middleton Enterprises (the family office of the co-founder of HomeServe, which sold for £4.1 billion). They’re going from 6 locations to 20 in two years, and their CEO says they expect more rounds to be played indoors than outdoors in London within a year.
And this is just the brands we know about. X-Golf has 139 U.S. locations. Tee Box has its Trackman-based training studios. Golf Crypt operates the aggressive “semi-passive investment” model. GOLFZON Social is expanding with Troon. Puttshack has 40+ locations globally.
Franchise Fever is real. But the last time the off-course golf market got this hot, someone lost $900 million.
The Topgolf Warning
Topgolf is the elephant in every room of this conversation. At its peak, the company was spending an estimated $30 to $50 million per venue. When interest rates jumped from near zero to above 5%, the financing model flipped. Same-venue sales declined 3% in 2023, 9% in 2024, and roughly 10% into 2025. Callaway eventually sold 60% of Topgolf at approximately $1.1 billion — roughly 45% below its original acquisition price. Close to $900 million in value, gone.
Topgolf’s concept was sound. People loved hitting balls into a massive net with a drink in their hand. The cost structure was the problem — sustained high-volume traffic was required to service the capital, and when novelty decay set in (the thing that happens when “hey let’s go to Topgolf” stops being a new experience), the traffic softened. The economics had no room to absorb that softening. This is the warning baked into every indoor golf franchise pitch right now.
The question that matters: can the economics work over a 10-year horizon when the novelty wears off? We know people will play indoor golf. The unknown is whether the demand floor is high enough to support 20 new locations per month from a single brand. Let’s look at who’s actually winning this race.
The Segmentation
The indoor golf franchise market is splitting into three distinct models, and they have almost nothing in common besides the word “golf.”
Model 1: The Premium Hospitality Venue
Represented by: Five Iron Golf, Puttshack, X-Golf
These are full-service venues with food and beverage, staff, leagues, events, and premium pricing. Five Iron’s average unit volume of $2.7 million is impressive until you look at the build-out cost: $1.96 million to $4.66 million per location, including a 7% royalty on gross sales. The F&B component pushes these toward restaurant margins, not golf margins. Food costs, labor, and rent eat into that $2.7 million fast.
Five Iron’s model works in dense urban markets where real estate is expensive but foot traffic is high. Their biggest asset is that they’ve built a genuine hospitality brand, not a golf brand. People go to Five Iron for “the experience” — the food, the vibe, the date-night energy. The golf is almost secondary.
The risk: if the hospitality market shifts (recession, changing consumer preferences), Five Iron carries the highest fixed-cost burden. They need butts in seats and drinks in hands, not just balls on screens.
Model 2: The 24/7 Unstaffed Model
Represented by: Back Nine, Another Nine, Golf Crypt
These are the opposite of Five Iron. The whole point is no staff (or minimal) and no F&B (or BYO). Members get a digital door code and play whenever they want. The model strips out the two biggest cost centers in any venue business — labor and food — and replaces them with a membership subscription.
Back Nine’s economics tell the story. Per their FDD, the rolling 12-month average monthly revenue per location is $16,238 (about $195,000 annually). Build-out cost: $276,000 to $604,000. That’s a much thinner revenue stream than Five Iron, but the costs are proportionally thinner too. No chefs, bartenders, servers, or host stand — just simulators, a keycard system, and a cleaning crew that comes once a day.
The 24/7 model is a real estate play dressed as a golf business. You’re buying an asset that generates $16K/month with almost no variable costs. If you own the building, the math works beautifully. If you’re leasing in a market where rents rise, the margin shrinks fast.
Golf Crypt is the most aggressive version of this thesis. They tell franchisees the model is designed so you do not need to quit your job. Initial investment runs $246,000 to $999,000 depending on how many bays you want. The flagship Jupiter, Florida location reportedly operates at over 50% profit margins.
Model 3: The Training Studio
Represented by: Tee Box, The Swing Bays
These are smaller footprint concepts focused on coaching, practice, and club fitting rather than entertainment. Tee Box runs on Trackman. The Swing Bays uses Foresight hardware. Both target serious golfers, not the “night out with friends” crowd.
The economics are different because the customer intent is different. A golfer who books a Tee Box session is there to improve their game, not to drink beer and take photos. They’re less price-sensitive, more likely to return, and more likely to buy lessons and packages.
The risk: these are niche concepts serving a smaller addressable market. The “I want to work on my swing” crowd is smaller than the “let’s hang out and hit balls” crowd. But the customers are stickier and the margins are cleaner.
The Numbers That Matter
Five Iron Golf: $2.7M AUV, $1.96M-$4.66M build-out, 7% royalty. 37 locations (30 company-owned, 7 franchised). Growing 68% in two years.
Back Nine: ~$195K annual revenue per location, $276K-$604K build-out. 150+ locations, opening 20/month. Growing at a pace that’s hard to verify independently because the growth numbers are self-reported and the FDD only tracks 22 locations.
X-Golf: 139 U.S. locations, $1M-$2M build-out. The largest franchise by count, but the concept is older and less flashy.
TeeGo (UK): 6 locations → 20 in two years. Seven-figure investment. CEO predicts indoor golf surpasses outdoor golf in London within a year.
Another Nine: 75+ territories sold, $334K-$824K build-out. First franchised location opened 2026.
These numbers reveal a market that’s growing fast but hasn’t been tested by a downturn. Almost every brand in this space launched or accelerated post-2020, when COVID created a surge in demand for private, bookable, indoor activities. That surge has normalized. The question is whether the demand floor is high enough to support 20 locations per month from a single brand.
The Silent Killer: Novelty Decay
Every indoor golf franchise faces the same problem that killed Topgolf’s valuation. “Playing golf on a simulator” is a new experience for most people, and new experiences eventually become familiar. The novelty decay is structural — it hits every leisure concept eventually.
The operator who can create repeatable, habitual behavior across their customer base wins. The operator who depends on new customers walking through the door loses.
This is why the membership model matters. Back Nine and Another Nine sell access, not sessions. A member who pays $90/month and visits twice a week is worth more over 12 months than the same customer paying $40/visit four times. The subscription creates a habit. The habit creates retention. The retention creates predictable revenue that a lender can underwrite.
The numbers bear this out. A facility with 200 members at $175/month generates $420,000 in annual recurring revenue. That’s more than double Back Nine’s reported $195K average, because Back Nine’s number includes a mix of members and public tee times.
The Korea Benchmark
South Korea shows what a mature indoor golf market looks like. Golfzon alone powers over 51,000 simulators globally, with an estimated 102 million rounds played annually and more than 6 million registered members. More rounds of golf are played indoors than outdoors in South Korea. The domestic Korean screen golf market generates an estimated $1.5 to $2 billion in annual venue revenue.
The US market is nowhere near this. The GolfSim.co directory tracks roughly 3,800 indoor golf venues in the US. Even at generous assumptions, the total US market is maybe 15,000-20,000 simulators. Golfzon has 51,000 globally and most are in Korea.
The gap between where the US is and where Korea is represents the bull case for indoor golf franchises. If 6.5% of US golf facilities have simulator technology today, and Korea is at effectively 100% penetration, there’s a lot of room to grow.
The bear case: Korea’s indoor golf culture developed over 20+ years with different demographics, real estate economics, and social norms. The US trajectory could follow a different path entirely. The US market may top out at 10,000 venues, not 50,000. Time will tell which trajectory we’re on.
What This Means for Home Sim Buyers
The franchise boom matters for our audience — the guy building a sim in his garage — in four concrete ways.
1. Better technology at lower prices. The franchise boom creates massive demand for launch monitors, screens, projectors, and software. Back Nine alone needs thousands of Full Swing KIT units. Five Iron buys Trackman and Foresight in bulk. This scale pressures hardware prices downward for everyone. As Golfzon, Full Swing, and others compete for franchise contracts, the technology they develop trickles down to consumer products.
2. More sim golf content and leagues. The WSG/Topgolf partnership and Five Iron’s tournament programming create a competitive ecosystem that home sim owners can join. Evenplay Index already covers 200,000+ bays. The more venues that exist, the more organized competition there is, and the more reason you have to practice in your garage.
3. The convenience premium creates home sim demand. Every time someone pays $40/hour at a 24/7 venue, they do the math on what a home sim would cost. The franchise boom is the best marketing the home sim industry has ever had. It introduces hundreds of thousands of people to sim golf every month, and a percentage of them will want their own setup. The franchise venues are the farm system for home sim sales.
4. Equipment availability is the hidden risk. If every franchise is buying Full Swing KITs or Trackmans in bulk, consumer availability for those units could tighten. We’re already seeing this with Trackman iO — commercial demand is soaking up production capacity. Home buyers may face longer lead times for popular hardware as franchise build-outs accelerate.
The Verdict: Who Survives?
The 24/7 unmanned operators (Back Nine, Another Nine, Golf Crypt) will survive because their cost structure is resilient. Revenue can drop 40% and they still cover their mortgage. The model works in good markets and survives in bad ones. The question is whether the member acquisition cost stays low enough to fill 196+ locations while new competitors open next door.
The premium hospitality operators (Five Iron, Puttshack) will survive in top-tier markets but will struggle in secondary cities. Five Iron works in Manhattan, Chicago, and San Francisco where $200/month memberships are pocket change. It won’t work in suburban Kansas City. The brands that understand their market tier and stay disciplined about expansion will be fine. The ones that chase growth into wrong-sized markets will learn Topgolf’s lesson.
The middle-market generalists will get squeezed. The operator who builds a 6-bay venue with a bar, some staff, and mid-tier pricing — not premium enough for the experience seekers, not cheap enough for the practice grinders — faces the hardest economics. They compete with Back Nine on price and Five Iron on experience, and they lose both battles.
The shakeout is coming within 18 months. When interest rates stay elevated, consumer spending normalizes post-COVID, and the fourth Back Nine opens in the same metro area as the two that are already struggling to fill memberships — the consolidation will begin. The well-capitalized chains will acquire distressed independent venues at discount prices. The under-capitalized operators will close.
If you’re thinking about buying into an indoor golf franchise, the smart money says: wait for the shakeout. Let someone else prove the market in your metro area. Then buy their location at half the build-out cost when they run out of cash.
If you’re building a home sim, the franchise boom is good news. More people playing sim golf means more software development, more competitive infrastructure, and more reasons to justify the investment. The venues build the pipeline, and home sim owners are the ones who capture the endgame.
And for the guy in his garage at 10 PM, hitting balls into a screen with a $199 LM1? He’s already won. The franchises are fighting over the rest.
