Selena Gomez, one of the most-followed people on the planet, is being sued by investors who say her mental-health startup Wondermind was a hollow promise dressed up as a movement.

The complaint, filed against the singer and her mother and co-founder Mandy Teefey, alleges securities fraud and breach of contract. All of the claims are, for now, unproven.

The suit lands squarely on the fault line beneath the celebrity-founder gold rush, in which a famous name is stapled to a company and treated as a guarantee of substance.

Wondermind arrived in 2021 promising daily mental-health resources, riding a wave of well-funded mental-health platforms that pitched looking after your mind as something you could do as routinely as checking your email.

According to the plaintiffs, that promise never became a product. They say they invested nearly $1.2mn on the strength of commitments the company then quietly failed to keep, and, crucially, that they were kept in the dark while it did so rather than told the truth about where their money was going.
