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.

Everything starts by defining the goal. Then every piece below is decided and measured against it — so what you get pulls in one direction instead of five.

Planning and delivery
€3001 day

Backlog prioritisation

Based on your main goal, we decide together what the team should work on and in what order of priority that should happen, and more importantly, what should not be done right now.

€350per week

PRDs

I write the feature spec and align it with the developer before anything starts: what it does, what it does not do, and what counts as done. Use it to hire a freelancer, and to validate the delivery afterwards.

€1,2003 days

Quarterly roadmap

We plan together what the next three months are about and in what order, based on what the last quarter proved. Privacy and legal go into the plan before anything gets built, not after. You end up with a plan you can show the team and an investor.

€400per week

Sprint management

I make sure everything ships on time and that the team has all the information it needs to work without getting stuck. I answer questions as they come, track what is on track and what slipped, and when something slips I adjust the scope instead of letting the week go by. You follow progress without having to chase anyone.

Product discovery and UX research
Free

UX & AI audit

I go through your product the way a user would and show you where the experience breaks, what you are not measuring, and where AI makes sense in your product. If it doesn’t, I’ll tell you. Then we meet for 30 minutes and I tell you what I found.

€400per week

Continuous discovery — user interviews

I talk to your users every week: I recruit them, run the interviews, and bring you back what they said and what it means for the product. So the following week’s decisions come from evidence, not from guessing.

€5005 days

Usability testing

I put real people in front of your product or prototype and watch where they get stuck, give up, or do something different from what you expected. You get the problems ranked by severity, with what to do about each one.

€120an hour

1h consulting

Open sessions by the hour, for whatever you need: guiding your team on something specific, supervising a delivery, or unblocking a decision. You book only the hours that make sense.

Who I am

From a startup unicorn to build products with AI.

Gabriela Ruth

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.

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.
