Teads, a programmatic video ad platform, this week announced that its programmatic revenues from the period of January 2015 through August 2015 are up 300% compared to the same period in 2014.

The ad tech firm attributes much of its growth to open exchanges, where its “outstream” video ad unit has become available to an increasing amount of marketers. Teads says it initially rolled out its video ad unit via private marketplaces, but has since been led to open exchanges based on demand.

Marketers, however, have been split on how involved they should get when it comes to buying video inventory via open programmatic exchanges.

At the recent Programmatic Insider Summit in Tahoe, Calif., one agency executive (Razorfish’s Brian Leder) said it’s simply too risky, while another (Oscar Garza of Essence) said they do buy video via open exchanges because they “have mitigated the risk.”

Teads raised $30 million this January.
