N1 Circular

AI software for construction material reuse and circular economy management

German software suite that uses AI to scan digital bills of quantities and project data to identify recyclable and reusable materials in active or tendered construction and demolition projects, then manages, prices, and trades those materials through connected material-flow, marketplace, and plant-management applications.

Not publicly disclosed. CBInsights/PitchBook list the company at Series A stage with investor Holcim MAQER Ventures; other named investors/backers include Futury, BRYCK Startup Alliance, and D2XCEL, and the company cites support from the Baden-Wurttemberg Ministry of Economics via an AI Innovation Competition. Internal sourcing notes describe the round as Seed -- public databases and vendor statements disagree, so this is flagged rather than resolved. raisedGrowth Stage

Founded 2017 · Named users on vendor site: Heinrich Feess GmbH & Co. KG (earthworks/demolition/recycling), Holcim Deutschland GmbH (building materials, also an investor via N1 Trading GmbH), Max Wild GmbH (demolition/recycling). Company reports ~11-19 employees (LinkedIn); total customer count not publicly specified.

WHY IT EXISTS

Why This Tool Exists

The Problem

Construction and demolition materials that could be recycled or reused are frequently landfilled because construction companies, demolition firms, and materials manufacturers lack an efficient way to identify recycling potential across active and tendered projects -- manually reviewing bills of quantities and project documents for reusable materials is slow and rarely done at scale.

The Solution

N1's AI applications (Match Depot Analyser, Depot Scout) scan digital bills of quantities and project data to flag recyclable or reusable materials within minutes, then route that information into connected apps -- Site Depot for material-flow and depot management, Sell & Buy for a peer-to-peer materials marketplace, and Plant Manager/Plant Order for materials-plant and landfill operators -- so stakeholders can price, trade, and track material reuse across a project network.
