The story

How we grewKiwabi

Where they were

Kiwabi brings Japanese scalp science to the US, UK and Europe: a scalp massage hair essence, a deep-sea scalp cleanser and a gray-root color brush. The products converted once people tried them, but almost nobody had. The creator budget was small and the market rate was not: influencers quoted an average of $1,505 per post, which would have bought about twenty posts a year.

What I decided

I decided to stop buying reach and build a funnel that never switches off. We gifted product with no strings attached, and creators who genuinely loved it moved up to paid deals priced by audience tier, not by their ask, at $99 on average. Each month focused on one product and the people who cared most about it: creators with visible grays for the color brush, new mothers dealing with postpartum shedding for the hair essence. Every story carried an affiliate link or code, and when creators pushed for upfront fees, we showed them what other affiliates were actually earning on commission.

What happened

Thirty-three months in, 363 collaborations have produced 268 reels and 566 stories for $31,767 in total creator spend, about $38 a post. The 221 posts we track earned 3.57 million views, and one creator with 17,000 followers reached 463,000 views on a single post. The program has driven more than $300K in affiliate and creator-attributed sales, a 10x return from affiliate sales alone, while Kiwabi’s own team ran the paid amplification. The engine is still running, and in 2026 Kiwabi asked me to take it into India.

Key takeaways

What madeKiwabiwork

Negotiation

Influencers quoted $1,505 a post. I paid $99 on average, for 33 months. Creators got the product first with no strings attached, and only the ones who loved it moved up to paid deals, priced by audience tier, not by their ask.

Creator selection

A 17K-follower creator reached 463K views. We pick on content, not follower count. Each month focused on one product and the people who cared most about it: creators with visible grays for the color brush, new mothers for the hair essence.

Weekly reporting

Not one missed week in 33 months. Every collaboration, post and view goes into one weekly sheet. That is how we know 363 collaborations have produced 268 reels and 566 stories, at about $38 a post.

FAQ

Questions aboutthis program

Straight answers on cost, platforms and fit, from the team that ran it.

How much did Kiwabi's influencer program cost?

$31,767 in total creator spend over 33 months for 834 reels and stories, about $38 a post. Paid creator deals averaged $99, against the $1,505 per post that influencers first quoted. Kiwabi's own team paid for ad amplification separately.

Which platforms and formats did the program use?

Instagram Reels and Stories. Every story carried an affiliate link or discount code, so each sale could be traced back to the creator who drove it.

How did you find creators who actually sell?

We choose creators on content, not follower count, and match each month's product to the people who care most about it: creators with visible grays for the color brush, and new mothers dealing with postpartum shedding for the hair essence. One creator with 17,000 followers reached 463,000 views on a single post.

Is the program still running?

Yes. Thirty-three months in, the weekly reporting sheet has not missed a week, and in 2026 Kiwabi asked us to take the same program into India.

Could this work for my brand?

It fits D2C brands doing $500K to $5M a year whose product converts once people try it, but who can't pay market rates for reach. Book a free 30-minute strategy call and we will tell you honestly whether it fits.
