The thesis in one sentence

The infrastructure to digitize an Indian gym is good enough to test now — UPI Autopay supports recurring collections, GST on gym memberships moved 18%→5%, WhatsApp remains the practical SMB communication channel, and Cult.fit validated premium digital fitness demand without selling software to long-tail gyms. The next question is narrower: can GymStack prove paid renewal recovery and member engagement in 90 days?

Refreshed July 2026 from the Deloitte & HFA India Fitness Report 2025, Cult.fit's July-2026 DRHP, NPCI/Razorpay 2026 mandates, IDC India wearables, Tracxn, 20+ vendor pricing pages, and field conversations with the anchor customer (Pro Fitness Kankarbagh). The April 2026 v1 research is preserved in git history; the v1 engineering specs remain under /archive.
