Summ started with a question nobody could answer.

What happens when you are mid-career, at your peak, and your body starts working differently? You Google it at midnight. You book a clinical appointment and get told it might be stress. You buy supplements from Boots that do nothing. You start wondering if you are the problem.

The gap that Summ exists to close.

There are 13 million women in perimenopause in the UK. Most have no diagnosis. Most have never been told that these things are connected: the brain fog in their Monday meeting, the rage at nothing, the exhaustion that sleep does not fix, the joints that ache for no reason. All of it is the same hormonal shift.

The information exists. It is buried in research papers and clinical guidelines. But nobody has built it into a tool a busy professional woman can actually use. One that gives her evidence she can take to her clinician.

So we built it.

Summ is a perimenopause platform for professional women. Tools that help you understand what is happening, track it over time, and take evidence to your clinical appointment.

The Symptom Pattern Checker tells you whether your pattern looks like perimenopause, thyroid, or burnout. The Daily Symptom Tracker measures sleep, energy, and clear thinking in 30 seconds. It builds a 14-day baseline. The clinical report gives your doctor structured data instead of a verbal description from memory. The Supplement Label Checker tells you whether your current supplements are actually working.

Everything is evidence-based. Nothing requires a diagnosis to use.

Who built this.

A service designer founded Summ after years building digital platforms for NHS Digital and running clinical trials communications at AstraZeneca R&D. A Women's Health Registered Dietitian developed the Summ Core formulation. She brings NHS and private clinical experience in perimenopause nutrition.

We are not a wellness brand. We do not sell hope in a jar. We build tools that give professional women the information they need to make good decisions about their health.

What comes next.

Something is coming in autumn 2026. If you want to know first, start with the checker and we will find you.
