Jean-Sebastien Corbel

📍 Branding. Content. Activation. Growth.

With my business name "SIZE UP", I support companies, startups, and freelancers in boosting their visibility, strengthening their credibility, and generating concrete opportunities through a comprehensive approach to marketing and communication.

🎯 My motto: Create actions that are useful to your business. No fluff.

I design tailor-made strategies and also handle production: branding, content, campaigns, acquisition funnels, automations...

🔧 What I can take charge of for you:

- Positioning, brand image & storytelling

- Content creation (LinkedIn, videos, newsletters, carousels, visuals...)

- Outsourced marketing management (strategy, planning, action coordination)

- Acquisition campaigns (inbound, outbound, SEA, SMA, SEO)

- Automation & tools (LinkedIn, CRM, email sequences, lead generation)

- UX/UI redesign (landing pages, conversion funnels, Figma mockups)

- Support for creating offers or business units (go-to-market, naming, sales decks, playbooks...)

👥 I work solo or with my collective of talents (design, development, video, writing...) to meet broader or more complex needs.

💼 My approach is both strategic (structuring, prioritizing, aligning) and operational (producing, testing, improving).

Do you have a team? I manage it. Are you alone? I do everything for you.

Need a hybrid profile capable of driving your growth, producing your content, or structuring your communication? Let's chat.

📍 LinkedIn. Video. Content. B2B Influence.

With KING SIZE, I help executives, entrepreneurs, and experts to speak with impact, build a strong and coherent image, and naturally attract the right opportunities.

🎯 My role: make you a visible, credible, and legitimate thought leader, without it becoming time-consuming.

💬 Specifically, I work on:

- Redesign or optimization of your LinkedIn profile

- Content creation (posts, carousels, videos, client testimonials...)

- Editorial calendar + optimized writing

- Recording and editing of LinkedIn videos (short, engaging, impactful formats)

- Influence and notoriety strategy on LinkedIn

- Personal positioning, storytelling, tone of voice, personal branding

- Tools and automations to make your content shine without spending hours on it

👤 Whether you are an executive, consultant, investor, or in transition, I help you formalize your uniqueness, express yourself clearly, and create real resonance with your target audience.

✅ No need to have a strategy already. I guide you, challenge you, I produce for you. And above all: I get you to take action.

Want to be visible for the right reasons? Let's talk.

At KING SIZE, we don't "make you an influencer": we help you become remarkable.
