Reddit is ramping up efforts to attract more users outside of the U.S., putting countries like India and Brazil in focus as it looks to unlock new advertising opportunities, a top company executive told CNBC.

In a wide-ranging interview, Jen Wong, chief operating officer of Reddit, said other platforms have 80% to 90% of users outside of the U.S. while about half of her company's current users are based internationally.

"So that points to a lot of our future user growth opportunity definitely outside of the U.S. and local language," Wong told CNBC. "The opportunity, the way I think about it, is every language is an opportunity for another Reddit."

Reddit has historically been an English-language platform, but the company is looking to expand its international reach with the help of artificial intelligence translations. This year, Reddit launched a feature that automatically translates its site into different languages.

Wong said that around 20 to 30 languages could be available by the end of the year.
