In the ever-evolving landscape of construction technology, a new player is emerging, poised to redefine precision and efficiency on job sites worldwide. LightYX, an Israeli construction tech startup, has just secured $11 million in Series A funding, led by NOVA by Saint-Gobain, the venture arm of the global sustainable construction giant. This investment, coupled with $3.3 million in grants from the Israel Innovation Authority, signals a significant vote of confidence in LightYX’s mission to revolutionize construction layout processes.
At the core of LightYX’s innovation is a proprietary electro-optical system that projects construction plans directly onto surfaces with sub-two-millimeter accuracy. This technology eliminates the guesswork and human error that often plague traditional layout methods, such as chalk lines and tape measures. By providing real-time, dynamic projections that adapt to changing site conditions, LightYX empowers construction teams to work faster and with greater precision, particularly in critical trades like drywall and MEP (mechanical, electrical, plumbing) installation.
“We’re replacing that with live, intelligent laser projection,” said Guy Ben-Romano, CEO and Co-Founder of LightYX. “This funding enables us to scale rapidly in the U.S. and Europe and transform how contractors work on-site.”
LightYX’s technology has already been deployed across hundreds of projects in the United States, covering over 25 million square feet of layout work. The company has built strong relationships with contractors, subcontractors, and distributors, particularly in sectors where precision and speed are paramount. These partnerships have validated the product in real-world conditions and laid the groundwork for broader adoption.
With the new funding, LightYX is preparing to scale aggressively. The company plans to expand its presence in the U.S. market, deepen its relationships with existing customers, and forge new partnerships across Europe. Product development will also accelerate, with a focus on enhancing the system’s capabilities and integrating it more seamlessly into construction workflows.
“We’ve seen tremendous traction with top-tier general contractors in the U.S.,” said Tomer Elran, GM of U.S. Operations and Co-Founder. “Our goal is to become the default standard for on-site construction layout, bringing precision and productivity to construction sites.”
LightYX’s success is part of a larger movement toward digitization and automation in the construction industry. As builders face increasing pressure to deliver projects faster, more efficiently, and with fewer errors, technologies like laser projection are becoming essential tools. LightYX is helping to redefine what’s possible on the job site, turning complex plans into clear, actionable guidance and empowering workers to build with greater accuracy and speed.
“We fuse optical engineering, real-time vision, and AI-based plan recognition into a system that understands construction logic,” said Uri Yehuday, CTO and Co-Founder. “It’s hardware and software innovation built from scratch specifically for field teams.”
The investment from Saint-Gobain underscores the strategic importance of LightYX’s technology in the future of sustainable construction. “Saint-Gobain invests in technologies that shape the future of building,” said Pierre-Emmanuel Thiard, CEO of Saint-Gobain Ecophon and board member of LightYX. “LightYX is solving a fundamental productivity challenge with a simple, elegant, and scalable solution. We are excited to support their vision.”
As LightYX enters its next phase of growth, the company is poised to make precision laser projection a standard part of how buildings are constructed—bringing clarity, speed, and confidence to every step of the process. With a growing portfolio of patents and a proven track record of performance, LightYX is emerging as a leader in construction innovation, ready to transform the industry one project at a time.
