Your trainers
Practitioners, not reciters
We only assign a trainer to a session if they use the technology in production. Their name and profile are shared at registration, before you commit to anything.
Our method
Training quality, guaranteed at every step
Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
Rigorous trainer selection
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
- Triple validation: technical, pedagogical, sectoral.
- Minimum rating 4.8/5 over the last 12 sessions.
You meet the trainer beforehand
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
- Live briefing on goals and team context.
- Veto right — we swap the trainer for free if needed.
Content tailored to your context
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
- Hands-on cases drawn from your stack and projects.
- Program co-written then validated by your team.
Continuous quality follow-up
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
- NPS, knowledge quizzes and skills self-assessment.
- Satisfaction guarantee: fully satisfied or free rework.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
Our social commitment
A school kit donated to a child for every training
To fight inequalities in access to education, Learni donates a complete school kit to a child in need for every training booked. You build your skills, a child heads back to school.
- Backpack, notebooks and essential supplies
- Distributed through our partner charities
- Included, at no extra cost to you
FAQ
Frequently asked questions
What does “confirmed session” mean?
The date is guaranteed: the session runs from the first registration and is never cancelled for lack of attendees. You can block the dates, book travel and start a funding request without waiting for a quota to be met.
Are two days enough?
Two days is enough to become autonomous on a specific tool, not to change careers. Foundational sessions start from scratch. Advanced sessions assume daily practice: that is stated on every catalogue row, before you register rather than after.
Is there a certification at the end?
No, and that is deliberate. These sessions target skills usable the day you return to work, not an exam. You leave with a certificate of completion, corrected exercises and the full material. If you need vendor exam preparation, write to us: we run that format in-company.
On site or remote?
Both, your choice, on the same dates. On-site sessions run at our hubs, remote sessions in a virtual classroom with the same labs and the same trainer. You choose when you book.
We are several people — is it still worth it?
From four people, a tailored in-company session costs less and adapts to your tools, your data and your real cases. The table above compares both. Tell us your headcount and we will point you straight.
Who runs the session?
A trainer who uses the technology in production. Their name and profile are shared at registration, before you commit.
Which funding routes are available?
Learni is a quality-audited provider and issues a detailed quote within 48 hours so your finance or L&D team can process it through your own budget.
