The go-to-market is channel-led: SIO AG sells through a network of trained Fachpartner (specialist partners) across Switzerland that handle professional installation, supported by a showroom in Olten, a dedicated accessories e-commerce shop (cover.ch/shop), a virtual exhibition, and trilingual (DE/FR/IT) digital properties for each sub-brand. Pricing is not publicly disclosed and the company has no disclosed funding, M&A activity, or management-team details in the source material. Customer segments are residential homeowners and the Fachpartner installer network; no enterprise or large-anchor accounts are named.
