Omnicom Takes Stake in Eisnor Interactive

Ad giant Omnicom Group has added another marketing firm to its portfolio of investments, with an agreement on Wednesday to take a piece of Eisnor Interactive, which has made its business doing offline promotions for online brands.

Financial terms of the deal weren’t disclosed.

The deal, besides providing Eisnor Interactive with money to grow, brings the company into relationships with all of Omnicom’s (OMC) companies, including consumer marketing firm Merkley Newman Harty, with which Eisnor will develop close ties. The two companies will partner on client work, as well as for new business pitches in some cases.

“We’re lucky to be able to partner with them and looking forward to what happens when they unleash their magic with some of our technology and communications clients,” says Stephen Harty, managing director of Merkley Newman Harty.

A relationship with Communicade, Omnicom’s digital media investment arm, will also likely become significant for Eisnor Interactive, since the smaller firm may be able to tap the Communicade companies for clients. Communicade investments include Organic (OGNC), Razorfish (RAZF) and Agency.com (ACOM).

Eisnor Interactive’s clients include TheStreet.com, Staples.com, MessageMedia, About.com, CNET, Nickelodeon, MapQuest.com, Homeportfolio.com, Homeruns.com and Pseudo Programs.
