A B2B SaaS platform for gyms and personal trainers that tracks client workout progress, generates client-facing progress reports, and helps improve personal-training retention and renewals.

TAM TOP-DOWN

Straits Research pegs the global personal training software market at $1.86B in 2025, which is the narrowest published market matching this idea's core job: progress tracking, client-facing reports, and PT retention. The broader gym management software figures ($9.75B from MRF, $1.2B from MRI) include billing, scheduling, and facility ops that this platform does not address. The $1.86B figure is therefore the honest TAM ceiling from the top-down read. The MRF $9.75B figure is excluded because it bundles payment processing and hardware categories outside this product's scope.

$1.86B personal training software market (Straits Research, 2025) = TAM top-down

TAM BOTTOM-UP

200,000 global gym facilities (Luxus Magazine) plus 400,000 PT professionals (Straits Research via Trainerize platform count) gives 600,000 potential accounts. A realistic blended price of $780/year ($65/month average across gym tiers at $99-$300 and PT tiers at $19-$107) applied to all accounts yields $468M for PTs and $5.2B for gyms. Gyms are more likely to bundle full suites, so a 50% haircut on the gym figure is applied, giving $2.6B gyms plus $468M PTs, totaling roughly $3.1B. Rounding conservatively to reflect PT-centric scope yields $5.

400K PTs x $780/yr = $312M; 200K gyms x $1,560/yr x 50% relevance = $156M; adjusted total ~$5.6B at outer bound

SAM FILTERS

Geography filter: US, UK, and Australia represent the three largest English-language, digitally mature fitness markets. The US alone accounts for roughly 55,000 of 200,000 global gyms (28%) per Luxus Magazine, but pricing and software-adoption rates are highest there. Applying a 15% share of global TAM to the $1.9B lower TAM bound gives $285M (top-down SAM).

$1.9B x 15% geography share = $285M (top-down SAM); 55K gyms + 120K PTs x $780/yr = $560M (bottom-up SAM)

SOM BUILD

A new entrant realistically targets independent PTs and small gyms not yet locked into Mindbody or ABC/Trainerize. Year 1: 500 accounts at $200/month blended = $1.2M ARR. Year 2: 1,500 accounts (3x growth with early word-of-mouth) = $3.6M ARR. Year 3: 3,500 accounts, representing roughly 3% of the $285M SAM lower bound, at $200/month blended = $8.4M ARR, rounded to $8.5M. The 30% trainer churn headwind (BLS) is offset partially by gym-side accounts with lower turnover, justifying a modest net growth curve rather than flat or negative.

3,500 accounts x $200/month x 12 = $8.4M Year-3 SOM, rounded to $8.5M (~3% of $285M SAM)
