Yusmary Martins

Growth & Revenue Consultant based in Île-de-France, near Paris. Fifteen years across direct sales, team management and marketing, the last two spent rebuilding a company's revenue engine from the inside, with the two teams I built along the way.

How I got here

I didn't start in a consulting firm. I started by knocking on doors. My first five years were pure direct sales, door to door and then in retail: the kind of work where every "no" feels personal and every "yes" has to be earned.

Then came team management: running stores, leading customer service, and eventually coming back to marketing, where I specialised in digital. I've kept studying and testing ever since, and I still do.

Today I work independently and remotely, with founders and small teams who need someone who has already carried a growth target. I travel to meet clients when it's really needed.

MYOS, from the inside

From August 2023 to November 2025. I was given the job of rebuilding a company's structure from the inside: creating two departments that didn't exist, sales and marketing, and building a retention system from nothing. I started on my own, with no agency behind me, and built both teams: 9 people in sales, me included, and 3 in marketing.

leads a month from paid advertising, with the budget going from €200 to €2,000 a month

In detail: paid advertising started at €200 a month, the budget that produced the first 700 leads, and stayed there until we had four salespeople. It only went up once the team could handle more leads than we were getting, levelling off at €2,000 a month with nine people and over 2,000 leads a month. It never needed more than that. SEO and checkout funnel optimisation brought in +15% in e-commerce revenue. On the retention side, a system that didn't exist before won back 35% of inactive customers, adding +12% in revenue, with an average order of around €600. And the sales team, built from nobody to nine people, me included, grew monthly revenue by 35%.

No agency, no predecessor, no team to inherit: I built both teams, sales and marketing, twelve people, me included, who carried the number with me.
