I asked the same question on HN 1450 days ago, see the responses I got: https://news.ycombinator.com/item?id=916622

Jaipur may not be the best place to start at this point in time but it definitely seem to have some future promises to offer.

I would like to bring to your notice that Entrepreneurship/Startup radar has picked up in Jaipur lately. Several events, groups have come up:

Some examples are:

groups:

startup jaipur: https://www.facebook.com/groups/jaipurtechies/

ceo jaipur: https://www.facebook.com/CeoJaipur

startup saturday jaipur: https://www.facebook.com/groups/ssjaipur/

events:

Startup saturday event is happening every month

Startup Jaipur also meets physically , a little infrequently though, since December last year. And I plan to do hackthons and stuff under this (I am one of the founding members and an admin on FB), a little short on bandwidth though, would like to take the lead and try a hand?

CEO Jaipur the first co-working space for/by/of the entrepreneurs started some time back. They have space to host other events too.

Then there were some events from TIE like 'TIE mashup' that recently happened.

more events:

Bringing startup weekend to Jaipur is in process.

Overall, it's heating up but agreeably not as mature or vibrant as Bangalore, Chennai, Hyderabad or Pune. ( Lived and experienced the first three cities and their meetups personally.)

I am from Jaipur too and I run a startup ( http://startuplabs.io/ ) here.

Let me know if you would like to meetup and hangout.
