Vlad and Niki are the latest YouTube stars to get a toy deal.

ZURU inked a deal through Haven Global to develop Vlad and Niki toys across several categories. The 7- and 4-year-old brothers have racked up more than 90 million subscribers in 12 languages across 15 channels. Since the launch of their English-language channel last year, Vlad and Niki quickly amassed 39 million subscribers and have since scored more than 19 billion views on that channel alone.

“With the escalating rise in content viewership, I’m extremely excited to have formed a licensing partnership with the children sensations Vlad & Niki,“ says ZURU Chief Operating Officer Anna Mowbray. “This engaging and dynamic brother duo, combined with ZURU’s world-class expertise in product design and distribution will undoubtedly lead to a phenomenal line.”

The first wave of toys is expected to hit retail next year.
