02 · The blind side
You are responsible.
Even when you are not there.
Companies change every day. Boards get snapshots.
Decidian watches in between.
03 · What reaches you
One alert that matters.
Not forty that don't.
Chatbots answer the questions you already have. Decidian finds the ones you did not know to ask.

One morning, illustrated. Sectors shown instead of names. Five quiet boards are the product too.

The world outside.
The papers on your desk.
Public intelligence and confidential context, held in one view. That is the whole picture, and nobody else has both halves.
96 percent

06 · The cost of finding out late
The worst question in a boardroom
is how did we miss this.
55%
of directors say at least one colleague on their own board should be replaced. The highest PwC has recorded.
PwC, 2025 Annual Corporate Directors Survey. 638 directors, fielded October 2025.
The reason given is almost never a scandal. It is that the person does not contribute to the discussion.
That gap is rarely about judgement. It is about what reached you before the meeting. The director who read the short-seller report on the way in asks a different question from the one who hears about it across the table.
Walk in as the one who saw it first.
Admission
Membership is by invitation.
Decidian is built for people who hold several seats and answer for all of them. We take on new members in small groups, so each one is set up board by board, by a person.
Referred
Most members arrive through someone already inside. If a chair you know sent you, say so and you go first.
Reviewed
We look at the seats you hold. If your boards are not covered well by what we watch, we say so rather than take you on.
Set up
Every board configured with you before the first alert. You see what we watch, and what we do not.
The invitation
No important decision should be made blind.
We are building the intelligence behind decisions too important to get wrong. It starts with the people who answer for them.
