MIX.E Energy Mix and Decarbonization Exhibition

From behind the scenes to the spotlight. From the first day of my internship to post-internship missions: what I did, learned, and want to share.

What is MIX.E?

MIX.E is a professional event in Lyon dedicated to energy and climate solutions, where industries, territories, start-ups and financial players come together to accelerate decarbonization. The 2025 edition took place on May 14 & 15, featuring conferences, exhibitions, business meetings and bilingual (FR/EN) content.

MIX.E recently joined the AEF info group — this merger strengthened its ecosystem and created natural bridges with PRODURABLE (shared audiences, content, and partners). The project is led by its co-founders, Paola and Stéphanie, who truly embody the spirit of the event.

Where I worked for 6 months…

Internship from January to June: on-site every Monday and Tuesday in a collaborative open space in Lyon with Paola, Stéphanie and Eliott, then remote work 3 days a week. Each person had a clear role and we used shared tools to stay aligned.

Why MIX.E made me grow

Because I was able to connect sales, editorial and operations — and see how every tiny detail can improve both the exhibitor and visitor experience.

What i did from scratch

1. Sales — Startup Academy (LinkedIn & web prospecting)

Targeting relevant start-ups through public databases, websites and energy clusters. Personalized LinkedIn outreach with clear, concise messages and simple calls-to-action. Qualification and follow-up in a tracker, connecting each prospect to the right offer.

2. Email, Sales Navigator & phone prospecting

Using Sales Navigator tags and notes to keep context. Writing cold emails and smart follow-up sequences, monitoring replies. Qualification calls (a 30-second pitch that could lead to meetings) and detailed recaps.

3. Exhibitor relations & Inwink back-office

Onboarding exhibitors (accounts, stands, company pages), answering frequent questions, tracking deliverables. Configuring Inwink: registration funnels, contact segmentation, clean exports, and testing transactional emails. Extra touches that made a difference: shared FAQs, collaborative checklists, and reusable email templates.

4. Bilingual content & conference editorial work (FR/EN)

Careful rewriting of session descriptions based on internal notes, while respecting the official titles (by theme: Industry, Tech/Digital, Energy, CO₂/Decarbonization, Building, Finance, etc.). Clarifying abstracts only when needed — keeping them short but readable. Bilingual harmonization (FR/EN): ensuring consistency in tone, terminology and style across the website, program and print materials.

5. Web, SEO & visitor experience

Website updates on WordPress (Elementor): program pages, exhibitor list, practical info. Example: adding a carpooling section with a CoviEvent share link to make access easier. Micro SEO optimizations: tags, internal linking, featured snippets, mobile readability.

6. Newsletters & CRM marketing

Design and moderation of Brevo campaigns with a strong MIX.E identity — bold yet readable, with clear CTAs (e.g. moving the badge button up). Accurate targeting from Inwink, contact cleaning, testing before sending, and monitoring key metrics (open, click, deliverability rates).

7. Logistics & signage

Preparing print materials while following strict specifications (sizes, formats, print-ready exports). Coordinating with service providers: deadlines, proofs, on-site installation, and visual consistency in both languages.

8. Brand & visual assets

Regular adjustments to logos, bilingual headers, and color harmonization. Social media adaptations (LinkedIn, teasers) aligned with the new editorial line.

The intense phase: when everything speeds up!

As the event approached, every move mattered — smart follow-ups (never intrusive), last-minute program fixes, and small web details that avoided friction (access, schedules, badges). That’s when I truly understood how an event works: every detail shapes the overall experience.

My on-site experience

  • Day 1: I was stationed at the welcome desk, meeting visitors and greeting speakers and exhibitors. I took a full tour of the stands to meet everyone in person. After weeks of remote exchanges, finally seeing them and the results of our work was deeply rewarding.
  • Day 2: I had the incredible opportunity to host the Agora stage all day. A unique experience — introducing speakers back-to-back, discovering innovative solutions for energy and decarbonization. I felt genuinely lucky to be part of it.

What i truly learned

  1. Prioritization creates value — distinguishing urgent from strategic means delivering better (and with more peace of mind).
  2. Experience is a continuous thread — before, during, and after the event. A well-onboarded exhibitor and a guided visitor make the event flow.
  3. Processes are empowering — checklists, templates, naming conventions aren’t “rigid”; they free up time for what really matters.
  4. Bilingual ≠ translation — it’s localization. Tone, meaning and promise must stay accurate in both languages.
  5. Tools are allies — Inwink (CRM & event), WordPress (live content), Brevo (clean distribution). When well configured, they disappear behind the user experience.
  6. Trust matters — giving visibility on progress, signaling blockers, and always proposing a Plan B. That’s how teamwork moves fast.

Thanks to the team & the MIX.E spirit!

Thank you to Paola and Stéphanie for their trust — during and after the internship. My mindset throughout: be useful, precise, and always communicate — respond quickly, anticipate needs, and document everything so anyone can pick up a project smoothly.

End of internship… not quite!

After my internship ended in June, I was lucky to be called back by Paola and Stéphanie. Since then, I’ve been contributing on two fronts:

Sales: preparing for the 5th edition.

Website: new sections, SEO fixes, and ongoing updates.

This extended collaboration allowed me to deepen my skills with full autonomy and the same trust from the team — while keeping the same goal: making things clear, efficient, and beautiful. MIX.E taught me how to connect strategy, operations, and experience — skills that are truly essential.
