Adir calls his second brain Adir 2, his number 2. It is a private folder of plain text files, opened with Claude Code, and it holds how he runs the company: the goals, the decisions, the fundraising, the team. He is not the only one with one: each of the 18 people at Autonomy AI has a number 2.

How it fits together

The setup, line by line

Front door
Claude Code, in the terminal on his laptop. Not on his phone yet: to answer an email with it, he opens the laptop. "It's worth it for now."
Storage
A GitHub repository of plain text files, with several branches and a copy on his computer. Every job it does leaves a file behind. He always works on the main branch; his number 2 decides which branch each piece of work goes to.
Folders
He calls it his core operating system: the cockpit, the vision, the goals, the execution rhythm, the decisions, the fundraising, the team and the playbooks.
Privacy
His folder is separate from the rest of the company's. Only he and his co-founder, the CTO, can open it; he can read everyone else's.
Connected to
Gmail, Calendar, Drive, Slack, Fathom for the calls, Linear, HubSpot, JustWorks for HR, and the company's own code.
Who builds it
His co-founder, the CTO, builds a number 2 for each person in the company.
Brand
One file made from a company deck. Decks and pages come out in the company's look, and it edits existing Google Slides in place.

How it stays current

A company's memory goes out of date as fast as the product ships. Adir's answer is a routine that runs every day and rewrites his file about the product from four places: the release notes posted in Slack, the recording of the daily meeting, the tickets closed in Linear, and what changed in the code.

His rule: connect the brain to the source of truth and refresh it every day, instead of finding out the data is wrong at the moment you ask.

A number 2 for every employee

Each person's number 2 is connected to the tools of their job. His VP of sales needed a security document for a large deal. It used to take a call with the DevOps engineer and the head of R&D, then marketing for the design. Now one request writes it from the code and the deal in HubSpot, and he sends the prospect a link.

The file behind that document is shared, so customer success or engineering can update the same one. And a new hire does not start from zero: the new marketing hire began with the head of marketing's playbooks, passed on as plain files.

What he uses it for

Email replies in his voice, and due diligence answers

An investor's question across six PDFs, answered in two minutes.
Call prep

One line typed; 11 emails and three calendar entries read; the prep written.
The daily team report, and a deck for sales on every release

What runs without him.

His advice for starting one

Put a Git folder under Claude Code and connect the tools you already use. Then do not give up early: it takes many rounds of feedback before it writes the way you do. And expect long runs. A hard question can take 10 to 20 minutes, and that is the work worth giving it.
