Former Solana advisor joins X as product manager, with an X financial card service expected to launch this year.

Elon Musk ( Elon Musk's community platform X welcomes the latest senior personnel change, with Nikita Bier, who previously served as an advisor at Solana Labs, officially joining X as the product manager. In the past, Bier sold two community apps he developed to Meta and Discord respectively, and now he personally announces that he has become a senior executive "by posting" and will focus on the integration of Grok and X.

Founded a community app sold to Meta and Discord, and also served as an advisor for Solana.

Bier is known for founding several virally growing social apps, the most famous of which are tbh and Gas. tbh is a social app focused on positive interactions, which was acquired by Meta for over $30 million in 2017. Gas, on the other hand, is a social app for teenagers that was acquired by Discord in 2022.

Subsequently, Bier officially joined Solana Labs as an advisor in March 2025, assisting in the promotion of mobile application development and ecosystem building.

Jokingly claimed to have risen to prominence through document crawling, starting to integrate Grok and X while enhancing dynamic features.

Time went back to shortly after Musk announced the acquisition of Twitter for $44 billion in 2022, when Bier actively posted that he was interested in becoming the product head of X. And just on July 1st of this year, Bier posted on X stating:

Hello everyone, I have successfully climbed to the product manager of X by posting.

Also posted a selfie with Musk, and this post was also retweeted by Musk himself. Bier added:

"X is the most important community platform in the world, internet culture starts here, and the most influential people globally gather here."

He will actively promote the integration of the AI chatbot Grok, allowing users to see a more personalized and real-time dynamic wall, helping everyone understand the various events happening in the world.

X not only wants to promote payment services, but may also launch financial cards this year.

Regarding Bier's role as an advisor at Solana Labs, coupled with Musk's long-standing support for Dogecoin )DOGE(, this personnel change has sparked discussions in the outside world, suggesting that X is likely to integrate DOGE and SOL into X's payment services.

In fact, X has obtained financial licenses in 41 states across the United States since 2023, and Musk announced in May this year that the online payment service "X Money" is currently undergoing internal testing. It is understood that X CEO Linda Yaccarino subsequently stated in June:

Users will soon be able to invest and trade directly on X. X credit and debit cards are also being explored and may be launched this year.

Overall, X's direction towards the community of "integrating financial payments and trading investments" has gradually become clear, but whether specific cryptocurrencies will be introduced still attracts external attention.
