Process

Five steps, in this order.

  1. Expression of interest on this page

    You choose your category and send us the details from the form — you do not need any documents for this yet.

  2. Initial review

    We compare your details with what our projects need and decide whether a collaboration is an option in principle.

  3. Request for evidence

    If it is, we request the evidence on your category’s list through a separate channel, which we will name at that point.

  4. Conversation

    We talk about scope, capacity and the projects your company could be considered for.

  5. Qualification and admission to the network

    If the evidence and the conversation hold together, we admit your company to the network and consider it when we assemble a project’s partners.

How we review

The scope of our review depends on field of activity, jurisdiction and transaction volume. The same principles apply to all partners; the depth of review follows recognised criteria.

Trades and service providers

Ten categories. Each one states whom we are looking for and which evidence we request in the next step.

Choose your category. The evidence and the form appear below it.
