Flexcity enables industrial and commercial sites to monetize electricity consumption and generation through demand response and load shifting. The stack—Kotlin, Spring Boot, Go, Python on GCP/Kubernetes—reflects a distributed-systems engineering foundation built for real-time grid orchestration. Heavy sales hiring (4 open roles) combined with sparse engineering capacity signals a go-to-market-driven phase, with pain points centered on expanding the industrial client base and accelerating commercial execution across Western Europe.
