Sure we all love AM I think. However you get to a point where there's more ideas then you can implement on your own. That's when you want to look to getting an office in my opinion. I actually hired 2 people before I had an office and they worked on my kitchen table a couple weeks. Really if and when you decide to grow to the next level you need people that are good at things. I'm terrible at design and you can only outsource so much. So I hired a designer. Oh I hate uploading and tweaking campaigns so I hired some people to do that. Don't have time for coding anymore so I hired a guy for that. Book keeping gets over whelming for just me at this point so I needed a book keeper. Yep you guessed it I'm terrible at writing copy so we brought on a full time copywriter. Hmmm what the fuck do I do all day
Seriously though my favorite part is the ideas. Building, investing and testing the ideas. Where I could setup a campaign and manage a few on my own. Now we can push out a campaign from start to finish in about 4-6 hours. Throw a bunch of testing money at it and then on to the next. Some work, some don't. It's a lot like a production line though in that each person has their role and we can function much fast and efficiently as a single machine.
At first I thought I wouldn't like having an office as the few I'd worked in were stuffy and lame. But honestly it's just like working at home now but I have a bunch of like minded friends around. Pretty cool if you ask me
