I wrote a post, well over a couple of months back (mid-Feb ’19), on the challenges of becoming a universal app or product in India. The nature of the Indian market meant few startups would attain product-market fit (PMF) across the country. Increasingly, startups would strive to attain PMF in India1 Alpha, India1 or India2.
The article also covered a broad approach to move across different layers of the stack, especially the India1 -> India2 journey, prescribing certain rules that product managers could use.
