atom42 has been instrumental to how I feel living in London. Instead of London being this cold place where people don’t make eye contact and everything costs a fortune, atom42 have helped me create friendships and showed me that there are cheap places to drink.

Here at Atom we enjoy challenges. Anything from improving a clients PPC campaign to canoeing across Scotland. Therefore, when one of our clients, haart, asked us if we’d like to support their charity Magic Moments by riding from London to Colchester (70 miles) we clearly had to say yes!

At atom we rely on MS Excel to do analysis on the fly and to store large quantities of data. Whatever you’re up to, an error message can often be frustrating enough to stop you in your tracks preventing you from getting to that juicy data. We’ve broken down some of the most common problems in a video here.
