N1 Circular Gmbh

What N1 Circular Gmbh does

N1 Circular GmbH is a German SaaS provider founded in 2017 (originally as N1 Trading GmbH) and headquartered in Dossenheim, Baden-Württemberg. Following a strategic pivot in late 2020, the company focuses exclusively on digitalizing material flow management (Stoffstrommanagement) for the construction industry, serving construction companies, building material manufacturers, recyclers, waste disposal operators, and municipalities primarily in the DACH region.

The company's core product is SITE DEPOT, a cloud-based platform for digital material flow management that combines interactive regional maps of suppliers and disposal sites, an AI-powered specification (Leistungsverzeichnis) analysis engine branded NIC.AI, and connections to a proprietary database of 8,000+ location datasets and ~6,000 qualified suppliers. Around SITE DEPOT, N1 has built a modular SaaS portfolio: SITE DEPOT Community (free network), MATCH MANUFACTURER (AI product matching), BODEN CHECK (regulatory compliance for the Ersatzbaustoffverordnung), SITE MANAGER (procurement database), PLANT MANAGER (site/service digitization), and SALES MANAGER (CRM and offer automation). The platform supports the GAEB tendering standard and integrates with ERP systems (SAP, BRZ), the INSITER industry portal, Madaster, and Mineral Waste Manager.

N1 generates revenue through monthly SaaS license subscriptions per location (e.g., €30/location/month for PLANT MANAGER), professional services for custom enterprise builds, and a freemium SITE DEPOT Community tier. Distribution combines direct inside sales, an industry-association channel (notably ZDB and LBB), and event-led demand generation through the Circular Table series. The company is privately held and bootstrapped apart from a 2021 state grant, with no disclosed institutional funding rounds to date.
