Fractional Chief of Staff

# A Chief of Staff, so the founder can *be the founder.*

Every week you decide between the urgent and the important. A Chief of Staff makes sure the important gets done, and that nothing falls through between people.

Joaquim Miro is a fractional Chief of Staff for founders through Miro Ventures. As Chief of Staff at Secure Digital Markets he scaled the team from 9 people to 40 and set up its marketing, operations, AI automation and HR. He works a few hours a week alongside the founder, paid in advisory shares.

In the seat

## What I do as your Chief of Staff.

- Turn the founder’s priorities into a weekly plan the team follows
- Run the leadership rhythm: meetings, decisions, follow-ups
- Set up the functions a growing team needs: marketing, operations, HR
- Automate the reporting and admin with AI, so the founder sees the numbers without asking
- Prepare board updates and investor reporting
- Take on the projects that belong to no one yet

My personal track record across prior ventures and my current role at GDA Capital. These are not investment returns, and they do not predict future results.

How it is paid

## Equity, not a retainer.

A few hours a week inside your team, paid in advisory shares rather than a monthly retainer: usually 0.5% to 5%, case by case, with vesting agreed per company. If you also need capital, an angel cheque of up to $25K can come with it. Every engagement starts with a two-week working trial, before any paper.

Questions

## Plain answers.

### What is the difference between a Chief of Staff and a COO?

A COO owns operations. A Chief of Staff works for the founder across everything: priorities, people, projects and communication. At pre-seed I often do some of both.

### Is a fractional Chief of Staff worth it this early?

When the founder is the bottleneck, yes. A few hours a week of structure usually gives back more founder hours than it takes.
