Where we stand

A support tool, not a clinical tool.

StackSafe does not diagnose, prescribe or replace a consultation. It surfaces what deserves a second look and hands the decision back to you and your doctor.

Every flag carries its reason, so nothing is a black box.

What it doesReads food, alcohol, supplements and medicines as one stack and flags conflicts.
What it never doesTell you to start, stop or change a prescribed medicine.
Our story

Twelve months on a ward, and the same failure kept repeating.

Not a knowledge failure. A visibility one. This is how Precivo started, and why the first product checks the boring things nobody writes down.

Prevention is quieter than intervention. It is also the part almost nobody is building for.

2023 to 2024 · The ward

A patient's medicine list almost never arrives in one piece.

There is the discharge summary. There is the repeat prescription. Then there is whatever sits in the cupboard at home: the vitamins, the herbal capsule a relative swore by, the painkiller taken every day for a fortnight without anyone being told. Three lists, three places, and no single moment where all of it is in front of one person.

The pattern

Every gap came down to time, not talent.

The knowledge was always in the room. What was missing was a way to see the whole picture inside the minutes available. Under that pressure the combination nobody had looked at was reliably the one that mattered.

Edinburgh

Clinical training tells you what is wrong. It does not tell you what to build.

A Doctor of Pharmacy covered the first half. An MSc in Entrepreneurship and Innovation at The University of Edinburgh covered the second, alongside work in pharmaceutical manufacturing development.

So I built the check I kept wishing existed.

StackSafe reads food, alcohol, supplements and medicines as one stack, flags what deserves a second look, and hands the decision straight back to you and your clinician.

About you

Used to tailor interaction checks and supplement suggestions. Nothing leaves your device.

Diagnosed conditions

Only what a doctor has actually diagnosed. StackSafe weights the checks around them.

What are you dealing with?

Pick any that apply. Suggestions are filtered against your stack so nothing clashes.

If you have chest pain, breathlessness, unusual bleeding, fainting or a sudden severe headache, seek urgent medical care. This tool is not for emergencies.
