Branded Products and Contribution to Marine Conservation

Siller GmbH provides access to a curated set of Siller branded goods through its dedicated platform at siller.store. 

These items reflect the firm’s commitment to clarity, structure, and disciplined design standards consistent with its advisory practice. Each transaction follows a transparent contribution model that supports a defined environmental objective.

For every item purchased, Siller GmbH allocates a fixed contribution of EUR 50 to The Cousteau Society, a nonprofit organization focused on the exploration, protection, and restoration of ocean ecosystems.  

The Cousteau Society is the official family‑connected foundation founded by Jacques‑Yves Cousteau, legally a U.S. 501(c)(3) nonprofit but operating as a global marine conservation organization.

Siller Consulting Clients may also opt for an extended contribution structure. When the full production cost of an item is additionally covered by the client, Siller GmbH transfers the complete amount, the EUR 50 contribution plus the production cost, to the same marine conservation program.  This arrangement ensures that both the client and the firm participate directly in supporting long‑term ecosystem protection.

The Siller Shop therefore functions as an optional extension of Siller GmbH’s broader environmental commitments, allowing clients to contribute to marine conservation through a clear, structured, and accountable framework while receiving a branded item that reflects the professional relationship.
