Who we are

A product network
led by someone
who's been there.

Mr. Marshmallow is a fractional CPO agency that allocates senior product talent into your startup, allowing you to bridge the gap and upskill your company easily and for a fraction of a senior salary.

The idea is simple: startups shouldn't have to choose between senior product talent and financial survival.

We're not a consultancy that leaves decks. We're not a staffing firm that places bodies. We're a curated network of senior product specialists activated on-demand for the right challenge at the right moment.

What we do

Our services

Different problems, different models. We offer two different types of services, both designed to bring senior product expertise to your team — without the full-time commitment or cost.

01
Most popular
Fractional CPO

We embed in your company a senior person to act as the CPO — part-time, at a fraction of what a senior full-time hire would cost.

02
For teams
Team Upskilling

A senior product specialist mentors your product team towards upskilling, giving them the tools, frameworks, and approach - for them to level up. Built around your actual gaps — not a generic training.

How it works

Four steps to
nail the goal

We implement a clear process for identifying your needs, and then deploying our solution — producing consistent results.

01
Diagnose

We make a deep discovery to understand your needs, the business, team, and stage, and propose a work-plan to best tackle them. We ask the questions nobody else dares to ask.

02
Assign

We match the right specialist to your project — based on the product, stage, challenge, and cultural fit. Not whoever's free. Whoever's right.

03
Operate

We get into the real work. Roadmaps, prioritization, hiring, frameworks, workshops. We do — we don't just recommend.

04
Transfer

We leave the knowledge, we leave the infrastructure - built. Processes embedded, capabilities built. Real, lasting results.

How we work

Not a solo freelancer.
Not a traditional agency.

A curated network of senior product specialists, activated on-demand. Marianela leads every engagement and guarantees quality — the right expert is matched to each project.

How we assign the specialist
One point of contact. The right specialist for every challenge.

Every project gets the expert for that specific moment — not whoever's available. That's not how most agencies work. That's exactly why we're different.

Areas of expertise

Where we create impact.

We could talk hours about product management, but chose some particular topics to master in. If you don't see your challenge here, don't worry - let's talk about it since for sure we can help anyways.

Why us

We've built
products like yours.

We don't advise from the outside. We've been in the room where the hard calls get made — with engineers, designers, investors, and users. We know what it takes to build something people actually use.

Marianela brings 10+ years of hands-on product leadership across 19 products in B2B and B2C. From 0-to-1 to scale, across FinTech, EnergyTech, EdTech, LogiTech, FoodTech, AI, Web3, and SaaS. She's led teams, hired PMs, fired PMs, defined strategy, and shipped product — not just recommended it.

That's the difference between a consultant and someone who's actually done the job.
