I know this feeling. I lived it.

You want the title.You want to be seen for the work you already do.

I’m Martin. In December 2013 I walked out of JKUAT with an IT degree, sat my first interview at Serianu, and discovered within a few questions that I had the vocabulary but not yet the judgment.

I’ve spent the twelve years since building the bridge I didn’t have: leading security operations across Kenya and Botswana, building a training cohort from scratch, and mentoring practitioners one conversation at a time. Today I’m Country Director of Serianu Botswana.

But right now?

You’re the one everyone calls when something breaks, and the last one in the room when decisions get made.

That isn’t a talent problem. It’s a path problem, and paths can be mapped. Start by finding out which stage of the climb you’re on.
