Overview of Practical Founders Podcast: “#206: He Sold at $3M ARR and Got a 10X+ Exit to a PE Buyer - Eran Galperin”
Greg Head interviews Eran Galperin, founder of GymDesk, about how he bootstrapped a niche SaaS business from a side project into a profitable, multi-vertical platform that reached a few million in ARR and sold to private equity in 2024 for a life-changing cash exit. The episode focuses on what made the company valuable to a PE buyer: exceptionally low churn, consistent growth, strong margins, and a product that solved a real operational pain for gyms and martial arts studios.
The GymDesk Origin Story
From martial arts hobby to software business
- Eran combined his technical background with his Brazilian jiu-jitsu hobby to build Martial Arts on Rails, later rebranded to GymDesk.
- He started with a simple idea: help martial arts schools manage:
- memberships and recurring billing
- attendance
- scheduling
- payments
- basic website and marketing tools
- He originally thought the product was a small side project, but it gradually evolved into a real SaaS business.
Bootstrap, not VC-backed
- Eran had previously tried the VC-backed path and experienced the downside of running out of money before product-market fit.
- This time, he wanted a bootstrapped, predictable B2B SaaS model.
- For several years, he kept a day job as a CTO while building GymDesk nights and weekends.
Growth, Product-Market Fit, and Go-to-Market
Slow bake, then real traction
- The business took about four years to truly find product-market fit.
- He points to early 2022 as the moment product-market fit became clear.
- COVID temporarily hurt the business because many gyms shut down or paused memberships, but the company adapted and retained strong customer relationships.
Product-led growth was the main motion
- GymDesk was not built around a traditional sales team.
- The company achieved strong conversion through:
- a simple trial flow
- onboarding improvements
- customer support and setup help when needed
- highly targeted product improvements based on customer feedback
- At one point, over 40% of free trials converted to paid accounts.
- SEO became the biggest acquisition channel, eventually driving more than 50% of new leads.
Content and SEO were compounding assets
- Eran’s first hire was a content marketing person.
- He described SEO as a technical founder-friendly channel because it behaves like an engineering problem:
- keyword research
- content structure
- pillar pages
- evergreen traffic
- The rebrand from Martial Arts on Rails to GymDesk was a major inflection point, helping expand beyond martial arts into:
- yoga studios
- gymnastics gyms
- small gym chains
- larger associations
Why Private Equity Wanted the Business
The metrics that mattered most
Eran says the PE buyer valued GymDesk because it had the kind of profile that growth investors like:
- Very low churn: under 1% monthly
- Consistent growth: more than doubled for multiple years in a row
- High margins: over 50% profit margins at the time of sale
- Strong product stickiness in a niche with real operational pain
- Payments revenue as an additional growth and margin lever
What made the deal attractive
- The business had moved from a niche martial arts tool into a broader multi-vertical gym software platform.
- Payments were especially attractive because they create recurring, high-margin economics.
- Eran learned that PE buyers look for stable, compounding businesses, not just hypergrowth.
The Exit and What It Took to Close
Deal structure and outcome
- In 2024, GymDesk was acquired by Five Elms Capital.
- Eran says the cash component of the deal was $32.5 million.
- After TinySeed’s stake, the broker fee, and taxes, he says he personally was left with around $24 million.
- He stayed on for about a year and a half after the acquisition and stepped away from day-to-day operations in October 2025.
Why he sold when he did
- Eran had been burnt out for years.
- He felt the business had reached the point where a premium sale made sense.
- He preferred to step down as CEO because founder-CEOs tend to carry more emotional weight from every operational issue.
Important lessons from the sale process
- He strongly recommends using:
- a sell-side broker
- a good M&A lawyer
- Due diligence was intense and stressful:
- legal and tax structure scrutiny
- representations and warranties
- attempts to retrade the deal
- He says the buyers tried to push for concessions, but his broker and lawyer helped him hold the line.
Life After the Exit
Moving to Japan
- Eran and his wife moved to Tokyo, Japan, in 2022.
- The move was motivated by:
- better healthcare expectations
- safety and quality of life
- his wife’s Japanese-American background
- his own history with Japan
- He says Tokyo offers the kind of city experience he values, while still being quiet and highly livable.
What he’s doing now
- After stepping away from GymDesk, he enjoyed several months of doing nothing.
- He has since started a new company in AI and real estate.
- He’s also interested in:
- angel investing
- mentoring founders
- possibly advising portfolio companies for a Japanese VC
Advice for Practical Founders
His main recommendation: survive long enough
- Eran tells bootstrapped founders in the “grind zone” not to quit too early.
- His advice: wait until you get near or past $1M ARR, because that’s often where the business starts to feel much less cramped and more scalable.
- He believes the hard middle stage is real, but it’s not wasted effort.
Build support before you need it
- One big unlock was hiring an operations manager around the point where the company reached roughly $750K to $1M ARR.
- That freed him to focus on the strategic and product work he was best at.
Key founder takeaway
- His story is a case study in how:
- patience
- low churn
- efficient acquisition
- strong margins
- and product discipline can create a valuable SaaS business without venture funding.
Notable Takeaways at a Glance
- Low churn is a ceiling-breaker for SaaS growth.
- SEO and content can become the best acquisition engine for a niche software company.
- Bootstrapping gives time to fully develop product-market fit.
- PE buyers love predictable economics: low churn, high margins, recurring revenue, and clear growth levers.
- A company does not need a huge team to become highly valuable if the fundamentals are strong.
