Via, Aura360 Team for Adventure Sports

BOSTON Sports-marketing startup Aura360 is close to a deal with its first high-profile client, Nike.

The athleticwear giant is expected to sign on this week as a sponsor of the Elite Adventure Team, a global adventure race team and client of the Portland, Maine, shop, agency executives said. Nike officials were unavailable for comment.

Media and marketing veterans Rory Strunk and Rufus Frost formed Aura360, which focuses on the action- and adventure-sports niche, in January.

Independent Portland ad agency Via has invested in the startup and plans to partner with the shop on pitches and projects.”Action-adventure sports is one of the fastest-growing worldwide event segments,” said Via CEO John Coleman.
