JCSM: the field first, no shortcuts.
The IRVE sector suffers from unqualified providers and a lack of traceability. Drawing on field experience since 2019, we created JCSM to fix that: building EV charging on the ground, not on a slide deck.
Why we do this
The problem
The mass rollout of EV charging stations in France revealed a major issue: in the field, unqualified providers, uncertified technicians, missing intervention reports and a lack of technical traceability are the norm.
Operators end up with mixed fleets – ABB, Alfen, EVBox, Kempower, Wallbox – and no single provider able to maintain them all. Each brand requires a different subcontractor, every fault becomes a logistical headache, and uptime drops.
The JCSM answer
JCSM was born from that observation: we needed to build a team of field technicians able to master every brand, respond fast with guaranteed SLAs, and act as a single point of contact for CPOs and manufacturers.
No middlemen. No generalists sent by default. Specialised IRVE technicians, trained in-house, with a timestamped, photo-backed report for every intervention.
Today and tomorrow
Since our first interventions in the Paris region, JCSM has grown with its clients. Growth happens in the field, contract after contract, station after station. In 2025, JCSM launched its installation activity. In 2026, France-based customer support and remote supervision will round out the offer, with a strong commitment to inclusion through the recruitment of agents with disability status (RQTH and AAH).
