BerlinRosen, a communications firm backed by O2 Investment Partners, has made an investment and partnered with Derris, a brand consultancy and communications firm.

Derris has assisted with launching and marketing brands such as Warby Parker, Everlane, and Glossier. The investment aims to grow brand consultancy and communications practice areas that expand upon BerlinRosen’s service offerings. Derris will continue to be led by Jesse Derris and Lisa Frank.

“Look at Derris’s track record; from Warby Parker, Everlane, Glossier to Reformation, it’s like a greatest hits track of the fastest-growing, most impactful brands,” comments Jonathan Rosen, co-founder and co-principal at BerlinRosen. “The common thread between all of them is Derris helping shape their narrative, message, voice, and story from day one.”

“Derris has demonstrated phenomenal success building brands in a marketplace that now more than ever requires consumer-facing businesses to uniquely differentiate themselves,” says Sean Darin of O2. “We are thrilled to bring on Jesse, Lisa, and the rest of the Derris team onto the BerlinRosen platform and are excited for the growth we will achieve in partnership.”
