Samuel Calef

Graduated from HEC Paris and Freie Universität Berlin, I combine solid experience in strategy, business development, and content creation. I have supported several start-ups and large companies (notably Veolia, Joko, Invecity, Atelier 22B) on missions of business plan construction, pitch deck writing, client relations, financing negotiation, and strategic communication (PR, video campaigns, social media).

In parallel, I have been developing my own company, Semantic, for a year, a SaaS mind-mapping solution to accelerate the reading and analysis of complex documents. This project has allowed me to strengthen my skills in product design, growth hacking, tech project management, and user value creation.

I am now working as a freelancer for companies seeking clear strategic vision, impactful storytelling, and agile execution, whether for a launch, a repositioning, or commercial structuring.

I also co-founded HEC United, an independent audiovisual initiative funded at €15,000, which gives a voice to alumni in a documentary YouTube format — a project at the crossroads of journalism, video production, and generational engagement.

Tools mastered: Excel, PowerPoint, Google Suite, Notion, as well as Lightroom and DaVinci Resolve for visual production.

Languages: French, English, German.

🏀 Personal side: I am passionate about basketball, cinema, and transmission — I coach, I teach (maths, economics), and I am constantly learning.
