AI-BOB: AI Copilot for Error-Free Building Design in Revit
Construction Tech

Beetroot assisted AI-BOB, a Swedish construction tech startup, with the development of its AI copilot. By embedding real-time validation and code checks into design workflows, we helped refine its Revit integration and backend logic, moving the product closer to error-free, sustainable construction.

Background

AI-BOB is a Sweden-based startup with a mission to stop buildings from being built wrong. The company aims to reduce construction errors that cost Sweden €10B annually (equivalent to 50,000 new homes) by using AI to streamline design validation and simplify compliance.

Its core product works as a copilot inside design environments like Autodesk Revit, giving instant feedback on compliance, accessibility, and quality. By catching issues early, AI-BOB helps teams prevent costly rework and reduce material waste.

Project Recap

  • As an early-stage startup, AI-BOB struggled to find the right engineering talent locally to grow its Revit-integrated copilot and backend.

  • Beetroot quickly connected AI-BOB with a BIM Software Developer to build and maintain the Revit plugin as part of a long-term dedicated team.

  • A stable, production-ready copilot inside Autodesk Revit, backed by scalable validation logic and a partnership running for over a year.

Challenge

As an early-stage startup, AI-BOB struggled to find the right engineering talent locally in Sweden. With ambitious goals for its Revit-integrated copilot and backend systems, the company needed additional technical capacity to sustain product growth.

AI-BOB faced several challenges:

  • A shortage of BIM and Revit engineering talent in the local market
  • Ambitious product goals for both the Revit plugin and backend systems
  • The need for a reliable in-tool experience for architects and engineers

Solution: Dedicated BIM Developer for Revit and Backend

Beetroot onboarded a skilled BIM Software Developer who quickly became an integral part of AI-BOB’s team, fully aligned with its roadmap. The collaboration follows a long-term dedicated team model and has been running successfully for over a year.

  • Revit Plugin Development

    A C#/.NET Revit plugin gives architects and engineers real-time validation feedback directly in their design environment, with streamlined auto-updates.

  • Accessibility Validation Rules

    A structured suite of accessibility rules covers a range of layout scenarios, so the copilot assesses different building configurations consistently and accurately.

  • Centralized Backend Logic

    Complex validation logic moved from the Revit layer to the backend, centralizing business logic on the server side and reducing technical debt.

Results

The collaboration resulted in a stable, production-ready integration of AI-BOB’s copilot within Autodesk Revit, helping architects and property developers catch construction mistakes early and validate designs faster and more accurately.

  • Product reliability

    A refined, reliable Revit-embedded copilot with auto-updating and in-tool visualization.

  • System scalability

    A robust backend architecture with scalable validation rules and centralized logic that reduces technical debt.

  • Long-term partnership

    An ongoing engineering collaboration that evolves as AI-BOB scales its impact across construction and property development.
