1
Complete a form with your company details: who you are, what you do, and how you can be reached. It only takes a few minutes, with no documents to upload in advance and no complicated technical steps to follow.
2
Describe your products or services following the provided guidelines: this is the most important step. The quality of the description determines your visibility to companies looking for a supplier like you.
3
The Tsubomi staff will verify your application. This is not an exam: it serves to understand the contribution you make to the customers' ESG journey, rather than to judge your company, its history, or its size.
4
Your profile enters the ESG marketplace: companies building their own sustainable supply chain can find you and contact you directly, without intermediaries or additional steps.
We look at what your product or service actually does: who it is for, how it works, and what problem it solves for a company building its sustainability report.
We evaluate the contribution you make to the customers' ESG journey: energy, training, consulting, or technology. What matters is consistency with the mission, not the sector you come from.
We do not ask for guarantees or a background check: you enter the marketplace by presenting your offer, not a file of documents to be submitted in advance.
We do not require a minimum turnover or a specific company size: you can apply as a freelancer or a structured enterprise, as it is the offer that counts.
If you produce your sustainability report with Tsubomi, you can offer any product or service on the marketplace, even without a direct benefit to your customers' reports: your profile will carry the Certified Supplier badge, providing an extra signal of reliability.
And if you have already completed your report elsewhere?
We can activate a dedicated due diligence service to verify your eligibility before granting access to the badge.
We take care of the rest: joining the Tsubomi marketplace is free and without any commitment.
