Graphite Fund IVIndustrial

The autonomous engineer for preconstruction design. Sidian turns a firm’s drawings, calculations, reports, standards, and project history into a company brain that can leverage past work for future designs, operating across the tools engineers already use. 

Problem

Engineering firms have decades of valuable knowledge buried across disconnected drawings, calculations, reports, BIM models, software, and individual employees. As a result, engineers waste time searching for information and recreating past work, while critical design decisions and best practices fail to scale across teams.

Solution

Sidian autonomously ingests and structures a firm’s historical project data into an engineering knowledge graph, creating a secure company brain. Through a web-based interface and local desktop agent, engineers can search past work, generate reports and calculations, and automate design tasks across their existing software.

Features Include:

  • Automated ingestion and structuring of drawings, calculations, reports, spreadsheets, and BIM files
  • Engineering-specific knowledge graph and company brain
  • Natural-language and visual search with source references
  • Local desktop agent connecting local files and tools including Revit, Bluebeam, Excel, and ETABS
  • Company-specific report, calculation, and preliminary-design automation

Traction:

Trusted by 7+ firms.

Business Model:

  • SaaS subscription
    • From $300/user/month
