How it works

As simple as sending a message.

01 — Onboarding
Week 1: we immerse ourselves in your brand.

No deliverables in week one. We listen. We visit on-site or work remotely. We talk to your customers, test your product. After the immersion, your Big Flux team is autonomous — they never ask you the same thing twice.

Free onboarding week — value €2,500
02 — Production
Submit. We produce.

Via ClickUp, you submit each request. Your queue is visible in real time. We handle one task at a time, in your priority order. No scoping calls, no meetings.

03 — Review
Approve. Or request a revision.

Each delivery is submitted for your approval. You approve or request a revision — handled within 24h. Unlimited revisions until the deliverable suits you perfectly.

Unlimited revisions included
04 — Total freedom
Leave whenever you want.

30-day notice by email. No penalty, no hidden clause, no annual contract. We'd rather earn your trust every month than lock you in.

What they say

Better than we could say it ourselves.

Travailler avec Big Neurons, c'est mieux que d'internaliser. C'est sans risque ni galère.

VB
Victor Bach
Co-fondateur @The Phone

Le process d'immersion a permis à l'agence d'être autonome immédiatement. C'est toujours un plaisir de les avoir chez nous.

JB
Jérôme Binet
Dir. Développement @Analyse & Action

Le process d'immersion fait vraiment la différence. Les livrables sont plus pertinents, les briefs réduits, les conversions nettement meilleures.

VD
Vincent Druesne
CMO & CDO @PPF France

Créative, dynamique, réactive. Toujours à l'écoute, force de propositions. Nous la recommandons sans hésiter.

MA
Mouna Apolinario
CMO @Maison du Menuisier

Enfin une agence qui comprend nos enjeux retail.

FAQ

Questions we get asked.

Is Big Flux strategy or execution?
100% execution. You bring the brief or creative direction — we produce. Big Flux does not do marketing strategy or consulting. For full strategic support, that's the standard Big Neurons offer. Big Flux is for those who know what they want and need it done fast and well.
Why an immersion if it's only execution?
The immersion isn't strategy — it's creative onboarding. We learn your tone, visual codes, and customers. Result: after week 1, we never ask you the same things twice. We deliver right first time.
How many requests can I submit per month?
Unlimited. We handle one request at a time in your ClickUp queue. No monthly cap.
I'm not happy with a deliverable?
You request a revision — unlimited, handled within 24h. We rework until you approve.
Can I really leave whenever I want?
Yes. 30-day notice by email. No penalty, no hidden clause.
Freelancers, AI, or a real team?
6 in-house profiles at Big Neurons. No subcontractors, no AI for production. Timothée Martella, founder, personally oversees each onboarding.
How long to get started?
Within 7 days. Signature → immersion scheduled → ClickUp space created. First deliverables within 10 days of signing.
