Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.
Don't let this gap widen
Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.
Dive into SolidJS reactive signals to replace React hooks, set up an advanced project with Vite and TypeScript, implement fine-grained reactive flows on real business cases, perform practical performance debugging exercises, produce a first scalable component with code review by the expert trainer, transform your development habits for native reactivity and zero boilerplate.
Build complex components with SolidJS portals and stores, integrate native accessibility via directives and ARIA, apply patterns like children props to interactive dashboards, test live with tools like Playwright, generate modular deliverables ready for the team, boost the maintainability of your professional UIs by avoiding unnecessary re-renders.
Master reactive stores for shared state without Redux, set up solid-router for advanced routing, implement SSR hydration with solid-start on e-commerce apps, simulate multi-user scenarios, optimize granular updates, produce a connected red thread prototype with local persistence, achieve business-critical performance gains for enterprise projects.

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.
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
