Mack Willow
Software that works for you
About
Mack Willow builds software the way it should always have worked. You speak to it in your own words, in your own language, and it answers in kind.
A few taps, a sentence spoken or written: the machine does the legwork, and your time comes back to you.
What we make
OneVet is practice software for vets who go to their patients. It grew from a long conversation between our founder, Max, and practising vets.
Max brings twenty years in scientific software: inside sales, business development, business analysis, sales management and Salesforce consulting. The vets bring the practice itself: how a house call really runs, what an emergency needs, what a certificate demands. A coding machine can draw the wireframe; their way of working is what finishes it.
They work with OneVet every day, and every question they raise goes from support straight into development. So it keeps getting better while they work.

How we work
Software built around clocks, forms and menus belongs to an earlier age. Ours listens, then acts.
Speak for speed, write for precision; most of us still like to gather our thoughts in words. This is simply where software was always heading.
Investors
We are building quietly, with real practices, before we build loudly. If that interests you, write to us.
