A project changes hands.

The information transfer nightmare.

A project runs for months….Sometimes years.

Then one day, the collaborator in charge changes.

What usually happens?

A few forwarded emails.

Some files attached “just in case”.

A handover meeting.

And a lot of missing context.

Because email was never designed to transmit knowledge.

Only messages.

IRISTIA changes that.

With IRISTIA, a project is not handed over via emails.

It is handed over via Heritage.

The incoming collaborator does not receive:

• copied inboxes

• forwarded threads

• duplicated files

They receive access to:

• the relevant email Patrimony

• the full history of exchanges

• the attachments in their original context

• the decisions, their timing, and their rationale

Nothing is moved.

Nothing is duplicated.

Access is granted — precisely, temporarily or permanently.

And this is where AI becomes meaningful.

Because the memory it works on is complete, considered, and unaltered,

AI can help reconstruct:

• the real state of the project

• the sequence of decisions

• the constraints and trade-offs

• the strategic options that were considered — and those that were not

Not guesses.

Not summaries of fragments.

But understanding.

This is not email management.

This is a new semantics for email.

Email is no longer:

• read / unread

• sent / received

It becomes:

• personal Patrimony

• shared Heritage

• project-based access

• continuity without disruption

• 
  

At individual level, the benefit is immediate:

• no reconstruction

• no loss of context

• no overload

Just continuity.

At corporate level, the benefit is structural:

– continuity across projects and teams– preserved decision history and timing– reliable, unaltered memory for AI and governance

Sustainable corporate memory.

IRISTIA doesn’t optimize email.

It redefines what email means.
