Athleta Gym

Why a Chennai gym switched away from a global gym-management product after 18 months.

"We looked at three other tools. Kasratbook was the only one that felt like it was built by someone who's actually run a gym."

The challenge

Athleta was using a US-based gym-management product. The features were rich but the experience was wrong for India: no UPI, no WhatsApp templates, prices in dollars, support tickets answered overnight.

Karthik was spending 30% of his time fighting the software instead of running the gym.

What they did

  • Migrated to Kasratbook in 2 weeks, including all members, payments history, and biometric data.
  • Replaced 8 distinct workarounds Karthik had built (Google Sheets, manual WhatsApp groups, separate UPI tracker) with native Kasratbook features.

The outcome

  • Member churn dropped 38% because the WhatsApp reminder cadence finally worked the way Indian members expect.
  • Support tickets dropped from 12-15 per month to under 3, mostly because the product just works.
  • Karthik now spends less than an hour per week on operations and the rest on coaching.
