Sonibel Instruments, a Vancouver-based industrial technology startup developing artificial intelligence-powered weld quality monitoring systems, has raised $1.6 million in an oversubscribed pre-seed funding round to accelerate the commercialization of its real-time weld defect detection platform. The financing will support product development, customer deployments, and expansion as manufacturers seek solutions to improve productivity while reducing costly welding errors across critical infrastructure projects.

The pre-seed round was led by Maple VC, with participation from Champion Hill Ventures, Dorm Room Fund, and a group of strategic angel investors. The company said the new capital will allow it to scale deployments, strengthen its engineering capabilities, and accelerate adoption across fabrication shops and industrial manufacturers.

Founded by University of British Columbia graduates Sophia Millar, George Hollo, and Hooman Pirouz, Sonibel Instruments was created to address one of manufacturing’s most persistent quality control challenges: detecting welding defects before they result in expensive repairs, production delays, and structural failures. The founders developed the company after observing firsthand how welding defects created costly bottlenecks during heavy industrial fabrication projects, particularly in shipbuilding and infrastructure construction.

The company’s flagship technology combines acoustic sensing with edge-based artificial intelligence to monitor weld quality in real time. A compact sensor mounts directly onto a welding torch and continuously captures the acoustic signature generated during welding. Machine learning models analyze these sound patterns to identify defects such as porosity, lack of fusion, lack of penetration, and slag inclusions while the weld is being created.

Rather than waiting for conventional inspections using radiographic imaging or ultrasonic testing after welding is complete, Sonibel’s system immediately alerts welders whenever potential defects are detected. This enables operators to correct problems before the weld cools, significantly reducing rework, inspection delays, and downstream production disruptions.

According to the company, traditional weld inspection often occurs hours, days, or even weeks after fabrication, meaning defective welds can create cascading delays throughout manufacturing operations. By shortening the feedback loop from days to seconds, Sonibel aims to help manufacturers improve throughput without changing existing welding workflows.

Chief Executive Officer Sophia Millar said manufacturers face increasing pressure to deliver major infrastructure projects while dealing with skilled labor shortages and rising production demands. The company believes artificial intelligence can augment experienced welders by providing immediate feedback rather than replacing skilled workers, enabling fabrication teams to achieve higher productivity while maintaining quality standards.

Chief Product Officer Hooman Pirouz drew inspiration for the company while working as a reliability engineer at a shipyard, where he witnessed the significant operational impact of weld defects. His experience revealed how delayed inspection processes frequently caused equipment downtime, production bottlenecks, and costly repair cycles that affected entire manufacturing schedules.

Chief Technology Officer George Hollo said recent advances in machine learning, acoustic signal processing, and edge computing have made it possible to analyze weld quality instantly without requiring cloud connectivity or disrupting fabrication operations. Processing information locally allows the system to deliver immediate notifications even in demanding industrial environments.

The newly secured funding will support continued product development as Sonibel works to make its system increasingly plug-and-play for customers. The company plans to improve calibration capabilities so its sensors can adapt more quickly to different acoustic environments, welding processes, and manufacturing facilities while expanding commercial deployments across North America.

Sonibel has already generated significant early market interest, building a growing pipeline of fabrication shops evaluating the technology. The company has also begun working with industrial customers on pilot deployments, including projects involving critical infrastructure manufacturing where weld quality directly affects safety, reliability, and project economics.

The startup’s solution targets industries including shipbuilding, structural steel fabrication, energy infrastructure, oil and gas, utility systems, and bridge construction, where welding quality plays a central role in operational performance and regulatory compliance. By identifying defects during production instead of after inspection, manufacturers can reduce repair costs, improve project schedules, and minimize material waste.

With fresh capital from Maple VC, Champion Hill Ventures, Dorm Room Fund, and strategic angel investors, Sonibel Instruments is positioned to expand deployment of its AI-powered weld monitoring technology. As manufacturers increasingly adopt intelligent quality assurance systems to improve efficiency and address labor shortages, the company aims to establish real-time acoustic monitoring as a new standard for weld quality control across critical industrial sectors.
