Influencing has proven to be essential for brand growth in the 21st century. But the unrestrained growth of influencing has resulted in a lack of diversity, and all too often, little or no connection between influencer and product.

This is no good for sustainable brands, who need influencers that embody their ethos. We only work with sustainable brands. Why? 


Consumers don't want to be bombarded with endless adverts for products that they don't believe in, and we don't want to ask influencers to advertise them.

We work with music-influencers, who are dynamic, diverse, and DIFFERENT. Most importantly of all, musicians are passionate about the environment. Musicians already share a connection with their fans, and their fans trust their opinion. 

How do we know? The stats speak for themselves. A typically 'good' engagement rate on Instagram is around the 3% mark. Musicians tend to hit 8-15%, even for sponsored posts.

Through PETRA, you can choose how you'd like to connect with music-influencers, using either our platform or our agency.

We connect sustainable brands with the music-influencers they need.


Sustainable Fashion Week


29 Jun 2021

SFW is the first fashion week of its kind, with a focus not on next season’s trends, but instead on activating the community and making sustainable fashion inclusive and accessible. SFW will be hosting a week of creative and community-led activity in the UK in September 2021, following their four themes of Regenerate, ReWear, Repurpose and Reconnect. They’ll stage a curated programme of informative panel discussions alongside mini-engagement events held in community spaces, by the community.

the ask

What they’d love is to ask music-influencers to direct people to their IG page and website, asking followers to join their September programme.

Additionally, they would love for influencers to participate themselves in Sept - hosting a mini event either in person or online to reach out to their community and encourage them to make changes in their relationship with fashion. They would promote and showcase these events as part of the programme.
