The Numbers
$624 in Google Ads. 13 new school signups. February through April 2026.
At $175 per month and 12-month average retention, each school represents $2,100 in estimated annual revenue — a 43.7x return on a $48 cost per signup.
The B2B SaaS average is $50-120 per signup. This campaign launched at $48 — just under the industry floor — from zero account history. Context at B2B SaaS Google Ads benchmarks 2026.
The Vocabulary Problem in Niche SaaS
Martial arts school management software is genuinely niche. The audience is specific: studio owners and operators of karate, taekwondo, jiu-jitsu, and MMA schools who need class scheduling, belt tracking, enrollment, and billing in one platform.
Building a campaign for that audience from scratch requires precision from day one.
The same words — dojo, class management, student tracking — are used by K-12 classroom management tools, gym chain operators, and fitness apps. None of them will ever sign up for martial arts school software.
The campaign was built around martial arts-specific management intent: dojo management app, martial arts studio software, karate school enrollment system, belt tracking software.
Adjacent vocabulary excluded immediately. The budget reaches studio operators — not everyone who ever managed a class of any kind.
Why This Gets More Efficient From Here
13 signups in two months is the starting point. Not the ceiling.
Smart Bidding needs conversion data to optimize. A two-month account has just enough to begin learning which terms produce actual studio owners.
Gym managers, educators, and fitness enthusiasts share vocabulary but represent zero conversion probability.
$624 in. $27,300 in estimated annual recurring revenue out. The cost per signup will fall as the algorithm accumulates data on which school operators convert. Two months old. 43.7x LTV return is the floor.
