Conxai SiteLens and DocNostic

Conxai Technologies GmbH is a construction AI company whose imprint lists an address in Karlsfeld, Germany. It builds a platform for the architecture, engineering and construction industry that structures unstructured data such as documents, plans, photos, videos and CAD files. In May 2026 it was reported to have closed a EUR 5 million Series A.

The platform uses agentic AI to automate knowledge-intensive construction workflows and extract cost and risk insights. Products include SiteLens for site imagery, DocNostic for documents, and a modular platform that lets customers start with one use case and expand. Configurable dashboards and API integration connect it to existing systems.

• Agentic AI: Automates knowledge-intensive construction workflows rather than only surfacing insights.
• SiteLens: Analyses site photos and video for jobsite insight.
• DocNostic: Processes unstructured project documents and plans.
• Reusable knowledge: Learnings from past projects can be applied to new ones.
• Dashboards: Configurable dashboards present cost and risk insights.
• API integration: Connects with existing systems and SiteLens integration documentation.

A Vietnamese general contractor could review tender documents and drawings for cost and risk flags. A project owner could analyse progress photos from large industrial park sites. A design-build firm could reuse knowledge from completed projects in new bids.

Cost and risk insights are extracted from photos, videos, documents and CAD files that otherwise stay unused. Knowledge from past projects becomes reusable. A modular setup allows a low-cost start with one use case, and security credentials include SOC 2 Type II and ISO 27001.

Contractors and developers generate large volumes of unstructured data across documents, drawings and site imagery, and AI agents are increasingly applied to estimating and risk review. Vietnamese general contractors working on industrial parks and high-rise projects face the same documentation load.

EUR 5 million Series A reported 4 May 2026, co-led by BayBG Venture Capital and Capricorn Partners with Earlybird, noa, Pi Labs, Argonautic Ventures and Zacua Ventures. Website lists SOC 2 Type II, ISO 27001 and GDPR. Funds are planned for international expansion.
