LONDON — Selbey Anderson, a new investment group building a network of boutique agencies, has bought UK consultancy Greentarget — its third acquisition since opening for business late last year.

Greentarget will retain its leadership, with co-managing directors Jeff Watt and Dafina Grapci-Penney continuing to run firm’s 20-person team. Since its 2006 launch, Greentarget Limited has focused on the financial services sector, working with clients on the buy and sell-sides of the business as well as in market infrastructure, financial technology and professional services.

“Greentarget’s goal is to cement its role as a leading communications consultancy to the global financial industry,” said group CEO Dominic Hawes. “I am confident that with the expertise and connections that the agency already has, coupled with the additional resources that we can provide, they will achieve this.”

In joining Selbey Anderson, Greentarget joins the two other creative firms that have been acquired since December — Orckid, which develops digital products for companies, and B2B marketing agency Hartley-Stone.

That puts Selbey Anderson halfway to its goal of acquiring up to six UK creative agencies yearly, a plan geared at creating a network that will provide clients options and flexibility, the company said. It was launched by veteran Hawes, who has spent his career in marketing; Simon Quarendon, a veteran of the PR industry; and investor Edward Goodchild.
