Build a sustainable marketplace with claims you can stand behind

Curate eco-brands, makers and second-hand sellers on one Shopify store. Check every brand's credentials, show what makes each product sustainable, and let customers filter by what matters to them.

Vegan America: 300+ plant-based brands · MyNextBike: second-hand bikes, GMV up 3.5x · Bazaa: vintage furniture, 5x revenue in 12 months

Two kinds of sustainable marketplace

Curated responsible brands. Organic, vegan, fair-trade, low-waste or locally made products from brands you vet. Vegan America runs 300+ brands this way.

Circular commerce. Second-hand, vintage, refurbished, consignment and rental, where the most sustainable product is the one that already exists. MyNextBike and Bazaa run this model.

Many marketplaces combine both. Garnet supports each model from the same store.

Turn sustainability claims into verified data

Customers of a sustainable marketplace trust you to check every seller. Garnet helps you collect evidence, not adjectives.


Vet brands at the door

Ask for certificates (B Corp, GOTS, Fairtrade, organic) as file uploads in your application form.


Structured product data

Fields for materials, origin, certifications, recycled content and repairability, required where it matters.


Filters customers use

Let shoppers filter by certification, material or country of making.


Lower-impact logistics

Fewer parcels

Garnet combines shipping rates from several sellers at checkout, and you can show free-shipping thresholds per seller to encourage fuller orders.

Local pickup

Let customers collect from nearby sellers.

Ship to a hub

Warehouse mode lets sellers send stock to your hub for consolidated shipping.

Frequently Asked Questions

Got questions about sustainable marketplaces? We have answers.

Ask a Question
  • What is a sustainable marketplace?

    A sustainable marketplace is an online platform that only sells products meeting environmental or social criteria, such as organic, fair-trade, second-hand or refurbished goods, from vetted sellers.

  • How do I start a sustainable marketplace?

    Write your criteria first and make them public, then recruit brands that can prove them. Collect the proof at onboarding, and add Garnet to a Shopify store to run sellers, commissions and payouts.

  • How do I verify sellers' sustainability claims?

    Ask for certificates and documents in the seller application, require structured product fields, and approve listings before publication.

  • Can I sell both new and second-hand products?

    Yes. Brands and individual sellers can sell on the same marketplace, with different commission rules.
