I have only just recently come across HelloMe looking through some design books and I really liked some of the stuff I have seen. HelloMe consists of one man, Till Wiedeck who is a Berlin based designer who has a wide range of design skills, producing branding, illustrations, editorial work for some high profile and low profile clients. He only set up HelloMe 3 years ago and has already, an impressive porfolio, style and ethos
"Besides working with a variety of commercial and cultural clients, HelloMe is a playground for visual experiments, self initiated projects and collaborations with like-minded people"
Not only is there examples of immense detail and precision but also a wonderful array of illustrative work (such as below) that gives him, as and agency, real width when appealing to clients. He also has a wonderful blog attached to his website that is really interesting to flick through.
