Freelancer profile translated to English.

Description

A psychologist by training, entrepreneur, and Product Growth consultant, I help apps, SaaS, and B2C startups with their positioning, user experience, conversion, retention, and growth challenges.

I co-founded Hypnoledge, an international language learning app, which I developed for nearly 8 years from its inception to a structured product reaching up to €1.5M in ARR. This experience gave me a 360-degree view of building a digital product: product strategy, UX, branding, acquisition, onboarding, retention, pricing, international development, recruitment, management, fundraising, and business management.

I also assisted Mangas.io part-time across their entire B2C Growth department, with a direct impact on performance: +500% MRR in 18 months. My role covered growth strategy, team management, funnel optimization, CRM, offers, conversion, retention, KPI analysis, and coordination with product, design, and content teams.

Today, I help founders and leadership teams identify what's blocking their growth: unclear messaging, poorly formulated value proposition, insufficient onboarding, low conversion, fragile retention, or scattered priorities.

My approach combines user psychology, product strategy, marketing, growth, and a concrete understanding of entrepreneurial challenges. I offer short audits to provide actionable diagnoses or regular support as a Product Growth Advisor / Fractional Growth Lead.

I am particularly effective when a product already exists but growth is not at the expected level: offering is difficult to understand, acquisition is too expensive, conversion is insufficient, onboarding is unengaging, or retention is fragile.

Objective: to make your product clearer, more desirable, more performant, and more scalable.

Co-founder & CEO of Hypnoledge, an international language learning app under hypnosis combining pedagogy, user experience, and innovation.

I participated in building the company from the initial idea to the development of an international digital product, with growth up to €1.5M ARR.

For nearly 8 years, I managed a 360-degree vision of the project: product strategy, positioning, user experience, marketing, acquisition, retention, branding, pricing, international development, recruitment, management, fundraising, and company structuring.

My role was to transform an idea into a product, and then a product into a business: understanding users, identifying the right growth levers, building a differentiating brand, optimizing customer journeys, prioritizing the roadmap, and making strategic decisions in a demanding entrepreneurial context.

This experience gave me a very concrete understanding of the challenges faced by startups and digital products: clarity of the offer, conversion, activation, retention, scalability, organization, financing, team alignment, and founder trade-offs.

Product and business model strategy
Positioning, branding, and value proposition
User experience, onboarding, and retention
Marketing, acquisition, and organic growth
International development
Recruitment, management, and team structuring
Fundraising, investor relations, and financial strategy
Overall company and strategic priority management

This adventure allowed me to develop a rare expertise at the intersection of product, marketing, user psychology, growth, and entrepreneurial strategy.
