The series is set in London (if I remember correctly). There are about 8-10 people (about 4-5 females and about 4-5 males) most of them (all?) are aged between 20 and 30 who start up together an IT company. The viewers of the series can follow them in the process of getting the company up and going but also follow them outside the building where the IT company is housed. I don't remember much but I can remember the most (all?) of them enjoy partying (quite a lot drinking, smoking, drugs etc.). I also remember that two of the women are lesbians. I don't know why, but I've a feeling the series is produced by BBC. I have also a feeling this series was quite popular and "should" possibly be a quite known series. Unfortunately I don't remember more than the mentioned, but hope it can be sufficient that someone knows which series I'm looking for.
