The buy-side startup’s clients include Dailymotion, Socialpoint and Twitch

Beeswax, a buy-side ad-tech company, today announced two C-suite appointments with the arrival of Paul Knegten as chief marketing officer and Bill Schild as chief revenue officer.

Knegten, formerly of MediaMath and Yahoo, and Schild, formerly of WeWork and Viant, each bring over a decade of ad-tech experience to the company. Both will report to chief executive Ari Paparo.

The dual appointments come at a time when the entire sector—both established titans such as Google and smaller startups—faces profound challenges amid growing public calls for data privacy that have led to changes in the entire ad-tech operating system.
