The white-label fitness app built for sports coaches.
Strength programs, sport-specific conditioning, performance tracking, and team community — under your name. Coach athletes across cities, countries, time zones. Launch in 10 days.
Athletes need more than spreadsheets.
You've built methodologies that work. Athletes who train under you get stronger, faster, more durable. They tell their teammates. Their teammates DM you for programs.
And you deliver those programs in Excel sheets sent over email. Wearable-data screenshots arrive on WhatsApp. RPE logs get scribbled in notebooks no one re-reads. You can coach 20 athletes 1-on-1 max, and that's the ceiling — unless you go scrolling-spreadsheet bulk delivery, which kills the personalization that made you good in the first place.
Your athletes would happily pay £40-99/month for structured programming with check-ins. The infrastructure to deliver it just doesn't exist as something you own — until now.
Saisei is performance coaching infrastructure under your name.
Your own coaching app, built for athletes.
Everything a sports coach needs to scale from 1-on-1 to programmed cohorts:
- Your name on the Apple App Store and Google Play (not "Saisei")
- Multi-week program builder — periodized, percentage-based, RPE-based
- Sport-specific exercise library with video demos (yours or ours)
- Athlete progress tracking — PRs, volume, intensity, fatigue, sleep
- Conditioning circuits and energy system training templates
- Cohort-based programming — assign one program to a team of 50
- Athlete check-ins (subjective wellness, soreness, readiness)
- 1-on-1 messaging tier — premium athletes get direct access
- Team community — internal feed for accountability
- Subscription tiers (e.g., £49 self-led, £99 supervised, £199 1-on-1)
- Direct payments to your bank — no markup on athlete fees
Coach 100 athletes, not 20.
Why programmed delivery beats hourly 1-on-1 coaching:
| Model | Capacity | Monthly revenue |
|---|---|---|
| 1-on-1 @ £80/session, 4 sessions/mo per athlete | 15 athletes (60 sessions/mo) | ~£4,800 |
| Saisei programmed @ £49/mo per athlete | 50 athletes | £2,450 |
| Saisei programmed @ £49/mo per athlete | 150 athletes | £7,350 |
| Saisei programmed @ £49/mo per athlete | 300 athletes | £14,700 |
The key insight: a coach who built programs for 20 athletes 1-on-1 can deliver those same programs to 200+ — without diluting personalization, because the app handles individual progress tracking, weight selection, and check-ins per athlete.
Why a branded coaching app beats generic platforms.
| Factor | Saisei (your app) | TrainingPeaks / TrueCoach / generic |
|---|---|---|
| Built for | Solo coach scaling 50-500 athletes | Endurance coaches or fitness studios |
| Branding | Your name in App Store, full white-label | Generic — your brand is hidden |
| Subscription billing | Built in — recurring auto-billing | You handle billing separately |
| Cohort programming | One program → 50 athletes, individual tracking | Per-athlete program creation |
| Sport-specific templates | Strength, conditioning, sport-specific | Endurance-focused or generic |
| Pricing | From £79/mo + small rev share | $10-30 per athlete/month |
What sports coaches are saying.
"I went from coaching 18 athletes 1-on-1 to programming for 140 in six months. The math is silly — same hours of work, three times the revenue, and athletes are getting better results because the app keeps them honest between calls."
— Ben Hartwell, Strength Coach, Leeds
"I run a youth football academy. Saisei lets me deliver age-appropriate programming to 90 players across three squads, with parents seeing the work being done. It changed how I run my business."
— Carlos Mendoza, Youth Performance Coach, Madrid
