US-based power tool company Positec has helped advertising company Lucid Commerce raise $8m in funding.
Positec was joined by venture capital firm Rho, which led the series C round, as well as venture firms StarVest Partners, OVP Venture Partners and Greycroft Partners.
Lucid is led by chief executive Tyson Roberts, one of the first employees at online advertiser aQuantive, which was sold to Microsoft for $6.6bn.
In April last year, Lucid raised a $5m series B round and in 2008 it raised a $2.5m series A round, according to news provider Xconomy.
Lucid owns Proceed Media Group, which tracks the performance of TV advertising.
