Non-fungible token (NFT) market SuperRare has announced a 30% staff-member cut as CEO John Crain discussed that the company mistakenly over-hired throughout the last bull market.

In a Jan. 7 tweet, Crain shared a screenshot of his message to SuperRare’s Slack channel announcing the 30% cut, stating that he had “some difficult news to share.”

“Startups are a balancing act of handling fast development while doing whatever possible to save limited resources. During the current bull run, we grew in tandem with the marketplace” he noted, including that:

“In current months it’s ended up being clear that this aggressive growth was unsustainable: we over-hired, and I take complete ownership of this mistake.”
