AI Product Manager on demand · EU based · Barcelona

Do you have a cool idea, or an AI solution,
that has been stuck for months?

I come into your business for a few hours a week to put the work in order, prioritise what matters, and get the project moving.

In plain terms

What exactly is a PM on demand?

It means having a senior product lead on your team without hiring anyone full time.

A senior PM in Barcelona costs between €68,000 and €72,000 a year — closer to €90,000 for the company once employer social security is counted. Instead of that, you pay only for what you need, and cancel anytime.

Services and prices

Hire services on demand.

Planning and delivery
€3001 day

Backlog prioritisation

Everything is urgent, and whatever the loudest customer asked for last week goes first. I order the whole list against the same criteria and write the reason beside each one — enough to defend it to a co-founder or an investor.

€350per week

PRDs

Your developer built what you asked for and it wasn’t what you meant, so it gets done twice. One or two specs a week end that: what it does, what it doesn’t, and what counts as done.

€1,2003 days

Quarterly roadmap

Next quarter’s plan is a wish list, and the privacy questions turn up after the thing is built. This one is built on what the last quarter proved, with legal and data settled before anything starts.

€400per week

Sprint management

Everything waits on you, and the week goes by with people blocked on an answer only you could give. I run the sprint, clear the blockers, and keep design and engineering pointed at the same thing.

Product discovery and UX research
Free

Product audit

I go through your product the way a user would and tell you where it breaks, what gets in the way, and where you aren’t collecting the data you would need to know any of it. One call, with no pitch at the end.

€400per week

Continuous discovery — user interviews

The last time anyone spoke to a user was months ago, so the roadmap runs on what the room believes. I interview them myself every week and read the behaviour data: what they were trying to do, and where they gave up.

€5005 days

Usability testing

We find where people get stuck in what already exists, or we validate a design with real users before anyone builds it. Either way you know in days, instead of after it has shipped.

€120an hour

1h consulting

Ask me anything, and we can find the best solution together. Or I step into specific moments of the product development, when that’s what you need.

Who I am

From a startup unicorn to build products with AI.

Gabriela Ruth
AI-nativeWellnessMobilityEventsHREducation
Wellhub
Unicorn · Product and UX

Every gym closed and the physical product stopped existing overnight. I helped take the product through its digital pivot, in weeks — the business kept running, and people kept training, at home.

Voltz Motors
Head of Product Design

Five products of the electric ecosystem delivered at once — app, ecommerce, bike dashboard, charging stations and support — while the company went from 13 to 80 people without the product breaking along the way.

The Cultural Club
AI PM on demand

A stalled project with no MVP. What shipped: over 3,000 cultural events updating themselves every 48 hours, and the whole site off Webflow in 13 days — monthly subscription gone, and the freedom to build whatever they want next.

Lumitype
0 to 1, alone

My own AI-native platform: from idea to a product in production, with no team, using Claude, Supabase and GitHub. Whatever I’d ask of your product, I’ve already asked of my own.
