Brands

The three brands I run.

Each one has its own documented palette, type scale, voice and editorial rules, and I never mix them up. I built all three from zero.

Julien Invest

Founder and Content Lead · 2021 to now

Investing explained simply, for French speakers aged 20 to 35.

Grew to 54,200 followers, 50,000 of them on TikTok, in a niche most creators avoid.
Built, priced and launched a 147 EUR course with 13 paying students, plus 97 EUR coaching.
Own the full pipeline: research, script, design, thumbnail, publish, sell.

CIEL BLEU

Content and Community Lead · 2024 to 2026

A Paris running collective. Not a competition club, and the voice had to sound like it.

Grew the account to 4,000 followers supporting 150 paying members this season.
Built the content system: brand charter, story templates, session and race day formats.
Hosted weekly sessions for 20 to 80 runners and turned them into the content pipeline.

How it gets made

How I keep them separate.

I use AI to publish faster without the brands drifting into each other. Each one has its rules written down once, and everything I produce is held to them automatically. In practice it means more output, and none of the sludge that usually comes with it.

Here is what that looks like when I sit down to make something.

Task	What the system loads
Instagram carousel	Brand tokens plus the carousel spec, then the export pipeline
Video script	Brand voice plus the short or long form structure
Course module	Pedagogy reference plus the deck and document templates
Partnership outreach	Prospecting reference plus the personalisation examples
Any published text	The editorial rules, always, on top of whatever else loaded

Design tokens as codePalette, type scale and layout declared once per brand, enforced on every asset it produces.

Hard brand separationThe finance world and the travel world cannot borrow each other's colours, voice or templates.

No invented dataA missing figure gets flagged, never guessed. Every number on this page is one I can evidence.

One call to actionEvery deliverable carries exactly one ask. No stacking, no diluted intent.

What I bring to a team

What I actually do.

I have run every part of a content operation alone, so I know what each part costs and where it breaks.

End to endI take a content idea from strategy to publication on my own, without waiting on anyone

GrowthAudience building from zero, offer and funnel design, partnership outreach and negotiation

How I got here

The short version.

2018 to 2021Sports science degree, then a teaching qualification. I start publishing on the side.

2021 to 2026Five years teaching physical education full time, while building Julien Invest, then Ju.en.vie, then running CIEL BLEU's content. Evenings and weekends.

2026The side work outgrows the day job. I leave teaching, run the Sydney Marathon, and move to Australia.

NowLooking for a content, social or growth role in Sydney, with full working rights to August 2027.

Teaching is not the thing I am selling, but it is why I can hold a room, explain something complicated in plain words, and hit a deadline every single week for five years.
