Hi. We're Harry and Kersten.
A few years ago, our marriage nearly didn't make it. What turned it around wasn't one big thing - it was a load of small things, and a piece of biology nobody had ever explained to either of us.
Harry
“A few years ago, our marriage was in a bad state. Honestly, I thought we were done.”
What turned it around wasn't one thing. It was learning about my wife's cycle and hormones - properly, for the first time, at 39. It was me having to grow up in ways I'd been avoiding. It was Kersten doing her own work alongside me. And it was both of us realising that most of what we'd been fighting about wasn't really about us. It was about biology nobody had ever explained and that kept getting in the way.
Who is Harry?
Quick honest version: I'm Harry. I live in Wales with Kersten and our two kids and a polytunnel that's somehow always full of flowers and questions.
Before all this I was a chef for over twenty years and a philosophy graduate. I'm also neurodivergent, which mostly means my brain has spent decades obsessively connecting biology, philosophy, nutrition, and how people actually work…long before any of it had a use. Turns out most of it had a use.
What I do now is make this stuff make sense to people. Mostly men. Mostly the bits nobody sat us down and explained…how her body actually works week to week, why the same conversation lands differently on day 5 versus day 22, what hormones are doing to both of you, why "communicate better" keeps not being enough on its own.
I'm not a doctor. Not a therapist. Not a PhD. I'm a guy who nearly lost his marriage, learned enough biology to stop blaming her for being human, and kept finding this stuff useful enough to share.
That's it. That's the whole pitch.
Harry
“Once I had the map, things made sense. But I still had to walk the territory. I'm never going to pretend hormones alone fixed our marriage — they didn't. But the understanding gave us something to stand on while we did the rest of the work.”
She's Not Crazy is what came out of that.
The Family
We live in west Wales. Me, Kersten, our two kids Merlin and Rose, and Dash…a black sprindagor puppy who has opinions about most things.
There's a polytunnel out the back. Most of what I make for She's Not Crazy gets recorded near it, or in it, depending on the weather and who's home. The brand started here because the conversations started here. Kersten told me, more than once, that calling her irrational wasn't going to fly anymore. Then she taught me why.
So I started learning. Then I started sharing what I learned. Then 500,000 people turned up!
This thing isn't a brand pretending to be a family. It's a family that ended up building a brand.

She's a PCC-certified coach, an NVC trainer, and a resonance healing practitioner. Fifteen years coaching individuals and companies. She runs her own practice called Feminine Mastery.
What this is and isn’t - quick frame for newcomers
She's Not Crazy is relationship education built on biology. The thesis is simple: most relationship arguments aren't really about the argument. They're about hormones, nervous systems, and the education most of us never got. Once you can see what's actually going on, a lot of the conflict stops being conflict.
What we're not: redpill, manosphere, therapy-speak, guru.
What we are: two people who almost didn't make it, who figured out enough to stay, and who keep finding this stuff useful enough to share.
If any of this sounds like your relationship
You're in the right place. There's a newsletter, there's a waitlist for the community, and there's a growing pile of writing, reels and podcasts working through this stuff one piece at a time.
No hard sell. Just biology, not blame.
