Kolverr

Kolverr delivers solar energy training. Initially focused on B2C through a web-based e-learning platform, the company faced growing challenges: disengaged learners, rigid formats, and an experience disconnected from real-life fieldwork.
‍
In 2024, Kolverr pivoted towards a bold vision:

Rebuild the product as an AI-first, fully conversational learning system — delivered entirely through WhatsApp.

The new direction aimed to serve both technicians and training managers by introducing:

• Sam, a WhatsApp-based assistant delivering and validating training at the learner's pace
  
• A library of expert-designed, modular skills ("savoir-faire") adaptable to different company needs
• An admin interface for creating, assigning, and monitoring training programs end-to-end

Problem statement

The original platform showed its limits:

• Technicians rarely completed training due to overwhelming structure and poor accessibility
• Companies had no way to personalize content or track learner progress in real time
• The learning journey was fragmented, jumping between tools and formats
• Content was hard to reuse, update, or evaluate consistently
• Validation processes were manual and slow, relying heavily on human mentors

Role and collaboration

I collaborated closely with Sixtine (CPO), Stanislas (CEO) and Numa (Software Engineer).

My role focused on:

• Leading user research with technicians and training admins
• Designing the full WhatsApp-based learning experience
• Structuring the CourseBuilder tool with Lovable and Supabase
• Designing the admin platform for enterprise training deployment
• Building a scalable design system based on Material UI
• Laying the foundations for product analytics and performance tracking

Approach

1. User Research

I ran extensive research cycles across four axes:

• How technicians interact with current product when on field and why
• How to restructure content into clear, modular "savoir-faire"
• How learners interact with Sam through WhatsApp
• How admins create and manage their own skills

We conducted field observations, interviews, and usability tests. Feedback was consolidated, prioritized by impact, and directly shaped product iterations — from onboarding to gesture validation flows.

2. Pedagogical restructuring & conversational design

We turned the traditional e-learning structure into a skill-based, conversational flow:

• Video introduction
• Key takeaways in short doc format
• 5-question quiz via WhatsApp Flow (retry if needed)
• Practical task with detailed instructions
• Photo submission of real-world execution
• Expert validation → Next skill unlocked

Sam also served as a real-time assistant on the field, helping users solve technical issues on-site.

I prototyped and tested multiple flows for gesture validation, ensuring both clarity and ease of use across devices.

3. Admin Interface & CourseBuilder

I designed the admin experience around real operational needs:

• Seamless enrollment and training path assignment
• Clear tracking of progression and validations
• Easy course generation via CourseBuilder, based on company-specific prompts
• Full interoperability with Kolverr's internal skill library

The interface bridged desktop workflows with mobile-based learner journeys, ensuring continuity from onboarding to completion.

4. Design System & tracking

To ensure visual consistency and measurable impact, I focused on creating robust design foundations and an analytics layer.

• Created a modular design system using Material UI, aligned with Kolverr's existing codebase
• Defined reusable components, navigation flows, and quiz layouts
• Collaborated with engineering on mobile responsiveness and theming
• Introduced a tracking plan for Sam, with KPIs like:
• • Onboarding completion
  • Quiz success rates
  • Skill validation
  • Documentation usage

This tracking layer supported product iteration and gave visibility into learning outcomes.

"It’s super handy on my phone, very clear and fun to use. I’ve learned a lot and even got my whole sales team on it so we’re aligned. The WhatsApp flow is great, reminders are well done, and I can always find the info I need for installs."

What I would do differently

• I would have pushed for an earlier rebranding (it finally occured right after my mission), aligning the visual identity with the clarity and ambition of the new product direction.
• I would have run earlier tests on tone, positioning, and messaging, to ensure alignment with user expectations and B2B clients.
• I would have anchored the product vision more deeply in user research insights, which were rich, actionable, and representative of real-world needs.
