01 — The challenge
A sensitive category where advertising claims carry little weight.
Mindbloom operates in mental health, where prospective clients are cautious and sceptical by default, and where brand-voice advertising struggles to establish trust.
A seven-figure media budget amplifies whatever creative it is given — including creative people do not believe.
“People considering this are frightened and doing their own research. They do not want a brand telling them it works. They want to hear it from someone who did it.”
So micro-influencers and real testimony were put in front of the media budget.
02 — Our approach
Authentic testimonials, then whitelisting and dark posting at scale.
Fifteen-plus creators went through the treatment programme themselves and spoke from that experience, which is the only version of this creative that holds up in a sceptical category.
Whitelisting and dark posting then put that testimony behind the seven-figure buy, cutting customer acquisition cost 25% and lifting referral sign-ups 40%.
