Google has held discussions about acquiring a video-sharing startup that could help it counter fast-growing TikTok, people familiar with the matter say.

Google is weighing a deal for Firework, a free smartphone app for users to share 30-second homemade videos with strangers. Like TikTok, Firework tries to surface viral, edited videos from unlikely sources, though Firework aims for an older audience than its better-known competitor out of China that is big among teens.

Firework, based in Redwood City, Calif., was valued at more than $100 million in a fundraising round earlier this year, and any acquisition would come at a premium. Google and Firework haven’t yet discussed pricing, the people say. The discussions may not lead to a deal and also include conversations about other ways to partner.

Weibo , China’s version of Twitter , has also expressed interest in Firework, though discussions haven’t moved as far along as those with Google, according to people familiar with the matter.

The move comes amid increasing regulatory heat on Google and its peers for their dominance of the technology landscape.
