Emma Rose · Product Leader Health Tech & AI · London

I scale products. I automate businesses. I build the AI myself.

Nutritionist, then Chief Product Officer of a £10m health business. Now I lead product teams and build AI automations for businesses.

Selected work

01 / 04

Four projects, four different jobs. One I built alone, one I shipped inside a big company, one a client paid for, and one grew a business until it was bought.

Stacks · Co-founder & sole builder · 2026Live with real users

A WhatsApp AI nutritionist, built end to end by one person

Stacks is a two-person venture; the build is mine. Molly chats to users about their goals, diet, lifestyle and blood work, then recommends a personalised supplement stack. She handles text, voice notes and photos, with a review dashboard and automated quality scoring behind her.

Fresh Fitness Food + Detox Kitchen · CPO · 2019 to 2024Acquired by Calo

From Google Sheets to the platform that carried a £10m business

FFF ran on spreadsheets and manual workflows. As the only product hire, I built the whole digital ecosystem: supplier ordering, client management, billing, kitchen operations, delivery logistics. Then an iOS app, then a second brand absorbed after an acquisition, then the migration onto Calo’s platform when we were acquired ourselves.

The platform proved strong enough to absorb an unplanned acquisition; the nationwide footprint mattered in ours.

An AI quoting agent for a family-run manufacturer

A family-run UK clothing manufacturer, drowning in manual quoting and missed follow-ups. I ran the engagement alone, from first call to delivery. The agent reads enquiries, prices them from a governed price list I set up as the single source of truth, and drafts an on-brand quote into the rep’s outbox. A person always presses send.

The client stays unnamed while the work is live; ROI is still being baselined, so none is claimed.

Calo Inc. · Principal Product Manager · 2024 to 2025Beta at departure

An AI health coach that closes the gap between logged and eaten

Calo’s number one reason for cancelling was "I’m not seeing results", usually caused by everything people don’t log. The coach lives on WhatsApp: photograph a meal, log by voice, answer a probing question or two, and next week’s plan adjusts. Clinical guardrails were defined with nutritionists, and I tuned the AI’s prompts myself.

Still in beta when I left Calo, so I make no retention claims for it.

About

I moved from clinical nutrition into product because a nutritionist helps one person at a time, and a product helps everyone who uses it. That trade has shaped every role since.

The science background still does daily work. A BSc in Human Nutrition and Physiology means I can sit between clinicians, engineers and commercial teams and translate between them. In health tech, where a wrong clinical detail costs user trust (or worse), not many PMs can do that.

I operate best with high autonomy and ambiguity: sole product functions, unplanned acquisitions, platforms built for one market being adapted for another. Give me clarity on the priority and the constraint, and I run with it.

"AI products don't fail because the model isn't good enough. They fail because they don't fit the workflow, there's no clinical rigour, or nobody defined success before shipping."

I hold that view because I've shipped three of them.
