Instagram's co-founders Kevin Systrom and Mike Krieger have resigned from the company, The New York Times reports.

“We’re planning on taking some time off to explore our curiosity and creativity again,” Systrom wrote in a statement, before hinting that the duo plan to develop a new product. “Building new things requires that we step back, understand what inspires us and match that with what the world needs; that’s what we plan to do.”

Instagram was bought by Facebook in 2012 for $715 million. Systrom wrote than him and Krieger were thankful for “the last eight years at Instagram and six years with the Facebook team.”

“Kevin and Mike are extraordinary product leaders and Instagram reflects their combined creative talents,” Zuckerberg said in a statement. “I’ve learned a lot working with them for the past six years and have really enjoyed it.”

However, Bloomberg reports that the move was sparked by internal disputes between the founders and Mark Zuckerberg. The article states that, according to unnamed sources, the founders "were frustrated with an uptick in day-to-day involvement by Zuckerberg, who has become more reliant on Instagram in planning for Facebook’s future."
