You can’t be an expert at everything. That’s certainly what Harris D. McKinney was thinking when he founded the world’s first B2B advertising agency in 1936. By concentrating his efforts on creating conversations between companies, this new agency model was able to uncover insights that spoke to business buyers like never before.
After 70+ years, HDM is still building B2B brands. Today, our interests lie in innovation — with clients in the science, healthcare and technology sectors. This industry focus is our foundation, enabling us to elevate our level of understanding more and more everyday. We work with companies looking to make a difference, and that’s why we believe in what we do.
