GoPro shares have hit a stumbling block in recent months, but founder and CEO Nick Woodman believes the camera-maker's holiday results and international outlook signal a smoother ride ahead.

After a dizzying climb from its $24 IPO price, investor appetite for GoPro has cooled in the past three months, sending shares lower by around 30 percent in that time. But Woodman feels that GoPro has a bright 2015 ahead.

GoPro saw especially strong holiday sales, Woodman said on Wednesday.

"For us and our customers and our retailers, it was a GoPro Christmas. It was the best new product introduction that we've ever had," he told CNBC's "Fast Money" from the International Consumer Electronics Show in Las Vegas.

Woodman also discussed the company's growth prospects in international markets.

"In absolute dollars, we have a lot of room to grow outside of the U.S.," he said. "Growth overall should be very healthy internationally in 2015, I don't think we have any concerns about that."

Woodman highlighted the synergies between GoPro cameras and drones, which could help drive growth both domestically and internationally.

"I obviously can't comment on potential future product introductions, but what I can say is that the drone market is fabulous for GoPro, and GoPro is fabulous for it," he said.
