Jedha

Jedha is a French training school for adults who want to move into AI, data, cybersecurity or product work. It sells accelerated programs that it says are recognized by the state and by employers, taught in French, either remotely or on one of its campuses, with the main campus at 116 Rue du Faubourg Saint-Martin in Paris. The site says it has offered certifying training since 2017, and founder and managing director Antoine Krajnc writes that the school has accompanied 4,000 alumni in their career projects. It is a learner product first: the reader here is someone changing careers, or a professional adding one specific skill.

How the programs are built

Jedha splits its catalog into two families. The "Formations Métiers" are career programs, built to take someone into a new job. The "Formations Skills" are shorter courses for one competence. The career programs come in levels, which the site presents as its signature: for each track there are up to three levels, Essentials (75 hours), Fullstack (450 hours) and Lead (150 hours), designed to follow one another. The FAQ says Jedha is "la seule école dans la Tech à proposer des formations par niveau" (the only school in tech to offer training by level), and it suggests a beginner aiming at data science take IA Essentials, then IA Fullstack, and perhaps IA Lead.

The four tracks:

• AI. Essentials covers Python for AI, prompt engineering, building AI agents, pipelines and automation with n8n, retrieval-augmented generation and vector databases. The Fullstack AI Engineer program adds advanced Python, exploratory data analysis with NumPy and Plotly, data infrastructure, supervised and unsupervised machine learning, deep learning, generative AI (Transformers, RAG, agents) and AI engineering with Docker and MLflow. The Lead level, titled MLOps Engineer, deals with data governance and AI compliance, GPU computing, orchestration, cloud architectures, MLOps and LLMOps, and monitoring.
• Data. Essentials starts with data mining, Tableau, SQL, cloud basics, Python, statistics and A/B testing. The Fullstack Analytics Engineer program moves through Google Sheets, advanced Python and SQL, NoSQL and data lakes, analytics engineering and Power BI. The Lead level is data engineering: Apache Spark, Airbyte, dbt, Airflow, lakehouse architectures and data quality with CI/CD.
• Cybersecurity. Essentials ends with a first pentest report. Fullstack covers threat intelligence, cloud, web app, network, Linux and Windows security, and pentesting. Lead adds advanced cloud and IAM pentesting, risk management and audits, incident handling, forensics and reverse engineering, and data protection under RGPD and CCPA.
• Product Builder. This track has two levels. Essentials teaches no-code development, automation workflows and data modeling; the Fullstack program, called Vibe coding, teaches AI-assisted programming alongside product management, UX/UI design, AI agents and RAG systems, CI/CD deployment and application monitoring.

The Skills courses are IA Générative (42 hours, with Claude, ChatGPT and Gemini), Cloud DevOps (187 hours, preparing the AWS Solutions Architect certification), Power BI (42 hours, preparing Microsoft's PL-300 certification) and ISO 27001 (42 hours, preparing the PECB Lead Implementer certification and its PECB audit counterpart). The site lists them as CPF-eligible, available part time or full time, and remote or in person.

Admission, language and format

Entry depends on the level. Essentials has no technical prerequisite, though the FAQ recommends a taste for math in data and AI and for computing in cyber and product. Fullstack is open after Essentials, or to applicants who pass a short technical test. Lead requires the Fullstack program or professional experience in the field. One requirement catches non-French speakers out: classes are taught in French, but most course materials, exercises and projects are in English, so the FAQ asks for written English at B1/B2 level.

Enrollment runs in three steps: a career-coaching call with admissions, a multiple-choice placement test, and a final stage where the team helps find funding and assemble the file.

The site says 70% of training time goes to practice, alone or in small groups, under the heading "Learning by doing". Graduates keep lifetime access to the learning platform. Cohorts are kept small, support is individual before, during and after the program, and the alumni community counts more than 4,000 people. The home page says professionals can choose among 14 campuses in France and Europe (Paris, Lyon, Bordeaux, Nantes, Lille and Toulouse are named), or study remotely from anywhere in the world, or mix the two.

Instructors are described as working professionals in the sector who teach alongside their careers. The ones shown include a senior pentester, a freelance AI engineer, a senior data consultant and a senior sales engineer at Dataiku.

Prices, funding and certification

The site's guide to state-recognized remote training lists the 450-hour programs at 7,500 euros each, for AI Engineer and Data Scientist, for cybersecurity, and for Data Analyst and Analytics Engineer. Each runs 3 months full time or 7 months part time. That guide names the credential each prepares: for AI, blocks 2 and 3 of the RNCP certification "Architecte en intelligence artificielle" at bac+5 level, plus preparation for AWS Cloud Practitioner; for data, block 3 of the same title; for cybersecurity, the state-recognized certification "Administrateur d'infrastructures sécurisées" at Master 1 (bac+4) level. The FAQ adds that every Jedha program prepares a professional certification registered with the RNCP or the Répertoire spécifique. The shorter Essentials, Lead and Skills courses carry no printed fee on the home page.

Funding drives the enrollment deadline, and the FAQ lists five routes: payment in one or several installments (sign up until 24 hours before the start), CPF (a legal minimum of 11 working days), a Société Générale loan (about 15 days to open the account), France Travail's AIF (at least 5 weeks ahead) and Transition Pro (a file submitted at least 2 months ahead).

Outcomes and reputation, as the school reports them

The home page states that 96% of alumni are employed one year after training, 97% feel better in their new career, and the median salary rises by 6,000 euros after a Fullstack program. It says these figures were calculated in 2026 across all programs from its annual placement survey and alumni LinkedIn profiles, and offers the full 2026 placement report as a download. A separate panel gives market figures by role, such as 47,000 euros for a junior AI Engineer and 42,000 euros for a junior Data Scientist.

The FAQ reports an average rating of 4.95/5 across 1,398 alumni reviews. It says Course Report named Jedha Best European Bootcamp (2025), Best Bootcamp Data (2022, 2023, 2024, 2025) and Best Bootcamp Cyber (2023, 2024, 2025), and that Antoine Krajnc launched the first data science bootcamp in France in 2018. Testimonials on the home page come from Charlène Dupont, who went from actuary to Data Scientist at AVISIA on the part-time Fullstack format, Tristan Giandoriggio, from 3D designer to Machine Learning Engineer at Animaj after studying remotely, and Sébastien De Coninck, who took all three cyber levels and moved from sales into pentesting.

Beyond the adult programs

Under the Jedha AI School name, the site also offers post-bac Bachelor (Bac+3, three years) and Mastère (Bac+5, two years) programs in AI and data for students under 25, on campuses in Paris, Lyon and Bordeaux, in initial or work-study format. The page states those programs are run by Quest Education Group. There are also free courses, online open-house evenings with admissions staff, and a page for companies that want to train their employees.

Who it suits

Jedha fits a French-speaking adult planning a career change into data, AI or cybersecurity who wants a structured path with a live cohort, a state-registered certification and access to French public funding such as CPF or France Travail. The level system helps people who are not starting from zero, since an experienced analyst can skip Essentials after a test. Working professionals can take the part-time format, which one testimonial credits for fitting around a job. The short Skills courses suit someone who only needs Power BI, AWS or ISO 27001 credentials. The main caveat is language: teaching is in French, so a learner needs French for class and solid written English for the materials, and the funding routes the site describes are French schemes.
