I have spent last 3 months working on something called 'UPSC Internet Report'

To give you an idea on scale of it, we've internally conducted online and offline surveys spanning across 50k+ aspirants online and ~1200 offline in ~12 cities.
Educators, mentors, teachers, entrepreneurs are separate.

It's gonna be a great resource for:

- Creators & Digital Entrepreneurs to navigate distribution on UPSC internet in age of AI

- Aspirants to know new updates in the market

- Ex-aspirants to build their own audience, and founders/mentors/educators looking to build personal brands

- Startups building in this space to map the market ship for building solid trust online

- Coaching institutions to understand how internet is scaling (and eating up their business)

Releasing within this month!

For me, this was a dream project. This market badly needs organization and this report will just reflect how UPSC Internet will look in next 2-4 years. :)
