A weekly letter on AI and the B2B service agencies it's changing.
My thoughts on AI, what I'm seeing at agencies, and how agencies are using it to improve their profit margin. Written by the co-founder of EfficiaLabs.

What I write about
- 01
How I feel about AI
What excites me about it and what worries me.
- 02
What's working with AI
Systems that are working for our clients. I'll explain what each one does and what it did to the agency's profit margin. Most of the time that comes from each person on the team being able to handle more accounts.
- 03
What I'm seeing
I work with B2B service agencies every day, so I get to see which AI tools teams keep using and how it's impacting their profit margin.
- 04
Where it's going
My guesses about the future of AI and what it means for agencies. I'll get some of them wrong.
