About

Perimenopause Bestie is building ALJA.

Perimenopause Bestie started by translating the research for women in perimenopause into plain language. It led to one conclusion: the information mostly existed. What was missing was somewhere to hold the whole picture of one body, over time. That is what ALJA is.

The founder

“I don’t ask you to take my word for anything. Every claim carries its source. If I can’t back it up, I don’t say it.”

Where the credibility comes from

The evidence, not us.Sources shown where you read them, clinicians being brought in to review, and the women who tell us what actually helped.

Why

Women’s health is fragmented.

A woman’s cycle is in one app. Her symptoms are somewhere else, if she has managed to write them down at all. Her sleep is on a wearable, her workouts in another app, her food in another. What she has learned about her body is scattered across podcasts, saved posts and a course she bought once. Her medical notes are somewhere else entirely.

All of it is happening in the same body, and none of it can see the rest. So the most important questions — what is changing, what keeps showing up, what tends to happen together, what is worth bringing to a clinician — go unanswered, not because the information doesn’t exist, but because it has never been in one place.

ALJA begins with perimenopause because this audience has a real, underserved problem and because it is where Perimenopause Bestie began. But it is built around the larger observation: a woman’s health picture should be one picture, and it should be useful.

The founder

An engineer, not a clinician.

I started researching perimenopause after watching my mom go through it — the dismissals, the “you’re fine,” the years of guessing at her own body. When I went looking for answers for her, I found that most of the information already existed. It was scattered across research papers, guidelines and forums, written in different languages for different readers, and impossible to turn into a decision about what to actually do on a Tuesday.

That isn’t a knowledge problem. It’s a systems problem, and systems are what I build. I’m an engineer, not a clinician. I can’t examine you and I won’t pretend to. What I can build is the thing that was missing: somewhere to keep the whole picture, understand what it means, and work out what is worth doing next.

So the credibility here doesn’t come from me. It comes from the evidence we cite, the sources we show you, the clinicians we’re bringing in to review this properly, and the women who tell us what actually helped. Read our evidence standards →

How it fits together

One company. Three names you’ll see.

ALJA is the next chapter of Perimenopause Bestie, not a different company. Here is what each name means.

ALJAThe company and the health platform. Software you log into, in development now, that keeps your changing health in one record that remembers you, sees your patterns and nudges gently. ALJA was called Bestie OS while it was being built.
Perimenopause BestieThe education and community you already know — the carousels, the Peri Brief, the Starter Guide, the plain-language research. It continues, and it is how most women will discover ALJA.
BestieThe warm, well-read guide inside ALJA. She remembers what you have logged and told her, answers in plain language, and always points you toward appropriate care. Same voice, new home.

What we stand for

The rules we don’t break.

Grounded in evidenceImportant claims trace to clinical guidance and published research. If the evidence is mixed, we say so, and never oversell.

Plain language, alwaysIf an explanation needed a translator, that’s on the system, not on you. We do the translating, and keep the science.

Solutions over fearNaming a symptom is step one. We point toward what is genuinely worth doing next — no scare tactics, no fake scarcity.

Your data is yoursNo ads, never sold, visible to you, and deletable by you. Privacy is a product decision here, not fine print.
