Energieversum
COSMO: mobile platform for a solar installer's daily operations.
Energieversum, part of the EnBW Group, has installed more than 40,000 photovoltaic systems. Valens helped them build COSMO, a mobile platform that brings sales, administration, project and finance work, plus customer interaction, into one system connected to the company's Microsoft tools.
The problem
Energieversum's teams ran daily operations across a patchwork of external tools from different providers, which cost time and made customer interaction harder to manage.
Our delivery
COSMO, a centralised mobile platform for sales, customer support, project and administrative teams, with a mobile app that also serves customers for onboarding, referrals and support.
How we worked
Project context
Energieversum is a photovoltaic company within the EnBW Group, with more than 40,000 installed systems and 14 service and warehouse locations. COSMO replaces a stack of external tools from different providers with one platform for internal teams and customers alike.
Delivery scope
Frontend, backend and mobile development, partial UX/UI design, project management and quality assurance. The scope covers backend and user administration, push notifications, CRM integration, project notifications, a customer success ticketing system, lead generation and onboarding, referral tracking and payment management, data synchronisation with the Microsoft tools stack, and integration of the document management system.
How we built it
The mobile app is built in React Native, using React Hook Form and React Query, on a NestJS backend with PostgreSQL. COSMO synchronises data with Energieversum's existing Microsoft tools and integrates with its CRM, document management system and other internal systems. Existing customers are being moved onto the new app, which handles support tickets, referral tracking and payment management.

Impact
