Helonic builds AI software that analyzes 2D construction drawings to identify issues such as coordination conflicts, code compliance problems, and missing information before they reach the field. The platform integrates with Procore and Autodesk to flag drawing issues that typically go undetected in manual plan review, helping construction teams reduce costly rework.

Alumni Q&A
- What is the core problem you are solving? Why is this a big problem? What made you decide to work on it?
- The founders address errors and inconsistencies in construction drawings that lead to rework, delays, and cost overruns, often only caught once building is underway and adding hundreds of thousands to several million dollars per project, part of an estimated $177 billion lost annually in the US to rework and coordination errors. Co-founder Blake grew up in a small town in Minnesota where many friends work in construction and heard about these problems for years.
- What is your long-term vision? If you truly succeed, what will be different about the world?
- The founders aim to build a system that automatically generates buildable, code-compliant building designs by learning from millions of construction drawings, reducing pre-construction from months to minutes. Their goal is to let someone describe a building in natural language and receive a complete design for a specific site.
