Honestly, not really IMO. Most of the action is in KL/PJ.

Cyberjaya is like the upcoming tech scene of KL imo. It has a growing number co-working spaces, plenty of decent accommodation for low prices, hosts many of big data centers including IBM, doesn't suffer from the traffic issues of the center, parks and greenery, air feels clean, is 15minutes from airport or 15mintues to KL sentral via the train etc.. I usually stay Citadines at DPulze which puts you pretty central and above a shopping centre, it's quite sparse so you'll need to GrabTaxi to different co-working places etc... If by action you mean nightlife it's meh, there a little pretend irish pub where locals smoke inside and few other sterile hiso venues, better hit Bukit Bintang if you need a beer or three (happy hour trend is 3x for some odd reason).
