Programmatic advertising marketplace TRUSTX, whose membership includes 35 premium publishers, has raised $2.2 million in growth capital from Meredith, ESPN, CBSi, Fox News and NBCUniversal.

TRUSTX now counts 22 publishers and hundreds of advertisers now currently trading on its marketplace.

Launched in beta in May of 2017 by nonprofit premium trade association Digital Content Next, TRUSTX’s new round of funding will be dedicated to increasing the growth and reach of its marketplace, which was built after the group recognized a need for a sustainable, trusted home for digital advertising.

David Kohl, President and CEO, TRUSTX, stated that “this new capital commitment will accelerate our goal of delivering more working media value for every dollar of media investment in programmatic advertising.”

Within the TRUSTX marketplace, buyers and sellers have the opportunity to “test and measure innovative ad monetization models,” in an arena that is transparent and safe.

TRUSTX and its members created a set of foundational principles that include a requirement that all ads must be 100% viewable to be monetized; the buying and selling of ads must be completely transparent to all members; and all members and TRUSTX must engage in complete financial transparency, including delivery, reporting and billing.
