About
One platform, and the team that gets you onto it.
Seqo builds the digital product passport infrastructure for batteries under the EU Battery Regulation.
Our mission
Build the data infrastructure of every battery, not one more document.
The difficulty is rarely technical. The data already exist, scattered between the ERP, the BOMs, the test reports and suppliers who never sent them, and the companies we work with have no compliance team to go and get them. The battery passport is our first deliverable, not our destination. The same data, once structured and linked to their source, will feed the obligations that follow. Product passport, carbon footprint, due diligence.
How we work
Four principles.
We measure before we propose
The attribute guide says what each data point means and where to find it. The platform checks at import.
We go where the data are
The documents to request from your cell supplier, the letter in English and Chinese, a dated log of requests and refusals.
Every value keeps its source
Each file is kept on European storage with the passport it produced. You can show where every published value comes from.
Your data stay yours
Processed on your behalf only, never resold. Exportable on request, in full at the end of the contract.
The team
Partners, not vendors.
You talk directly to the people who do the work.

Background
Two questions we hear
Before the first call.
What if my suppliers do not answer?
You get the request letter and the follow-up template in English and Chinese, a model clause for your purchase orders, and a dated log of requests and refusals. In front of an authority, a documented refusal is worth more than an empty box.
Do we need software on our side?
No. You fill in the Seqo templates from Excel and upload them. We set up your first three models with you, then your team works on its own, with our support by email.
