Quentin (Developpeur Libre)'s contact route, audience split and rate estimates are ready — members see them in one tap.
Quentin, widely recognized by his digital handle Developpeur Libre, is a tech entrepreneur based in France. He has established himself as a prominent voice in the French-speaking coding community by focusing on the practical application of artificial intelligence. While he keeps many personal details private, his background is rooted in software engineering and a desire for professional autonomy outside of traditional corporate structures.
His rise in popularity within the tech niche came from his commitment to 'building in public,' a movement where creators share their successes and failures in real-time. By transparently sharing his financial goals and the technical hurdles of developing AI apps, he attracted a dedicated following of students and professional developers. This transparency helped him stand out from typical polished corporate tech influencers.
Quentin's content is primarily educational and documentary-style, often featuring screen-recordings of code, AI tool demonstrations, and strategic breakdowns of his business model. He frequently posts updates on his 5K MRR challenge, showing the backend of his applications and discussing market trends in AI. His videos are known for being concise, technical, and highly relevant to the modern 'indie hacker' lifestyle.
As a self-described 'Developpeur Libre,' his primary business venture is the development of his own proprietary mobile applications and AI tools. He operates as an independent creator, focusing on generating revenue through software subscriptions rather than traditional brand sponsorships. His brand is built on the concept of 'liberty' through technical skill and independent product creation.
There are no reliable public estimates for Quentin's total net worth, as he is in the early stages of scaling his independent ventures. His income is primarily derived from Monthly Recurring Revenue (MRR) from his applications and potentially from freelance consulting or technical workshops. He is very open about his goal to reach a stable monthly income of 5,000 euros through his software products.
Quentin is not involved in traditional film or television, as his work is strictly centered in the digital tech space. His signature work consists of his public development logs and the specific AI-integrated mobile apps he builds for his audience. He is best known for his 'Build in Public' series on Instagram, which serves as his main creative portfolio.
The best place to follow Quentin's progress and view his technical tutorials is on his Instagram account, developpeur_libre. He utilizes stories and reels to provide daily updates on his coding progress and business milestones. He also maintains a presence across other developer-centric platforms where he shares his insights on AI and independent software development.
Quentin has successfully built a niche community of over 15,000 followers interested in AI development and entrepreneurship. A major milestone in his career is his ongoing progress toward his 5K MRR goal, which he tracks publicly for his audience. His growth reflects the increasing interest in the French tech scene for independent AI-driven business models.
Quentin (Developpeur Libre) has 15.1K followers in total, which puts this profile in the micro band (10k – 100k followers). The largest single audience is on Instagram with 15.1K followers — about 100% of the total reach.

Related questions
Quentin (Developpeur Libre) is based in France and posts in French. For brands that usually means the core audience follows the same market and language, with a long tail from everywhere else — big accounts rarely stay local.
The content sits in education and tech & science, so the people watching are self-selected for those interests. That is the useful part of a niche profile: a mid-size account inside the right category often beats a much larger general account, because the audience already cares about the subject.
If you need the same audience profile in another market, the country and language lists on CreatorFanBase let you line up comparable creators side by side instead of guessing.
If you are shortlisting Quentin (Developpeur Libre) for a campaign, these are the facts worth carrying into the brief. Everything here is stored data, refreshed on a schedule rather than typed in once.
A practical sequence: check the lead platform matches where your buyers are, check market and language, open the official account to see recent posting frequency, then ask for a media kit and rate card directly.

Quentin (Developpeur Libre)'s counts come from the platforms themselves via instagram public profile and are refreshed on a schedule; the most recent check was Oct 16, 2026. When a platform blocks a read, we keep the last verified number and show where it came from instead of filling the gap with an estimate.
Large jumps are treated as suspect: a sudden drop past our safety threshold is held back for review rather than published, which is why the numbers here tend to be lower-drama than screenshots circulating elsewhere.
