Programmatic video advertising platform SpotXchange says it will nearly double its headcount to service new premium publishers over the next year, after finding strong business growth in the last 12 months.

“The company saw 145% revenue growth this year in Q1, we saw 350% growth in terms of programmatic spend in Q1,” says the company’s platform and global supply VP Sean Buckley.

“We’re now over 150 employees globally. We plan to add at least another 100 by end of this calendar year.”

SpotXchange reckons it added more top-tier publisher clients during the quarter than rivals, signing Hearst Digital, Meredith Video Studios, Zynga, The Atlantic, Billboard and Mail Online.
