CTO
Excellence
in 100 days

Your first 100 days as CTO, ten days at a time.

01 / 10

Speaker notes: When I told my technology friends I was writing a book about the first 100 days, I got the same response every time: why 100 days? It's always a 90-day plan.

100
not 90.

“I've pushed the tried-and-tested plan up 10 days because there is an emotional connection to that number.”

Days 1–90+ 10

Speaker notes: Franklin D. Roosevelt took office on March 4, 1933, and what he would do in the first 100 days of office would shape his legacy and his country.

Lead as a first-class citizen of the C-suite.

As chief innovator and problem solver, the CTO's value far exceeds technology skills. The CTO must lead as a highly visible, first-class citizen of the C-suite. Still, many technology experts operate in a reactive, support-oriented style, struggling to command respect or assert influence—let alone executive presence.

Speaker notes: The work begins with assessing whether you're in the right place. Next, Etienne's methodical approach helps you build trust and visibility through effective communications and a strategic quick win, introduce your company's technology vision, and navigate challenges—from engaging stakeholders to managing conflict—all within that vital one-hundred-day period.
“If your goal is to be a world-class CTO, read this. If not, move along. …”
Todd Herman · Author of The Alter Ego Effect and 5x Founder
“Etienne is my go-to CTO coach for any SaaS founder and CEO. He is unconventional and brilliant. CTO Excellence in 100 Days is the gateway to his mind and a blueprint for any company's CTO.”
Dan Martell · Founder of SaaS Academy
“Etienne truly understands the role of CTO, which is why it doesn't surprise me that he wrote CTO Excellence in 100 Days. Every time we talk, his love for people and his craft shines through. As a fellow geek who has had to navigate the world of leadership, I recommend every technical leader have this book on their bookshelf.”
Sri Shivananda · Executive VP, CTO at PayPal

Speaker notes: Get user accounts for everything inside the company. No matter what it's for, get a user account and get inside it.

Keep your CTO journal

Every ten days in the book ends with journal exercises. CTO Notebook has them all, knows which day you're on and asks you that day's questions.

CTO Journal Exercises: Days 1–10
  1. Which subsets of each tool work best for each team?
  2. Make a list of projects that are currently running, and list ways you could immerse yourself in the work that’s already being done.
  3. Try the product and look at customer reviews critically. Note your findings.
  4. Record how the company is organized; who is in charge of what, outside and inside their official titles; and anything you see that needs to be changed.

From chapter 6. Every ten days in the book has its own.
