What The Yellow Nest Group S.l. does
The Yellow Nest Group S.l. is a privately held Spanish business and knowledge holding company, established in 2022 and headquartered in Terrassa (Barcelona), that consolidates six energy-sector subsidiaries under a unified energy transition and digital transformation strategy. The portfolio spans the full energy value chain: Smilics (smart sensors and electrical measuring equipment), KM0 Energy (zero-kilometer renewable decarbonization for municipalities), Nergix/NNERGIX (digital platform for solar PV prediction and control serving 19 countries with 11,000+ monitored sites via Sentinel Solar), Vector Energy (industrial automation and control in 50+ countries, partnering with LS Electric, Peter Electronic, New Elfin, and GIC), Zez Silko (power capacitors for energy storage and reactive compensation), and Saci (transformers, network analyzers, and metering equipment with 80+ years of history across 80+ countries).
The group's core technology layer combines Wibeee smart sensors and Wibeee Nest, an AI-powered platform for controlling energy consumption and generation across building systems, with SUNVEC photovoltaic systems, Sentinel Solar analytics, and passive building systems including facades, Canadian wells, and geothermal installations. The Vapor 4.0 corporate headquarters in Terrassa functions as an NZEB LEED GOLD-certified Living Lab that demonstrates the integrated stack with zero CO2 emissions. Combined headcount is reported at 501-1,000 employees.
Revenue is generated through three streams: hardware sales (sensors, capacitors, transformers, measurement equipment), recurring software revenue from Wibeee Nest and Sentinel Solar, and engineering and integration services across industrial automation and renewable energy. The go-to-market is sales-led and direct, executed through each subsidiary's website, the holding company's multilingual web presence (Catalan, Spanish, English), and dedicated LinkedIn channels. No pricing details are publicly disclosed. The holding structure, founding date (note: legacy subsidiaries such as Saci predate the 2022 holding formation by decades), and absence of disclosed funding, M&A, or revenue figures indicate a privately controlled industrial group with cross-sell potential rather than a venture-backed growth company.
