Semble AI is an autonomous fire and life-safety systems engineer startup founded in 2025, based in San Francisco. It offers an AI-powered platform that automates complex building-system design tasks for construction companies, drastically reducing the time and cost involved. The platform instantly generates code-compliant device layouts, bills of materials, project cost estimates, and proposals, eliminating manual drafting and permitting delays. Semble AI serves construction firms and system integrators who need efficient, compliant fire and safety system designs, addressing the traditionally slow, costly, and error-prone engineering process. Its rapid automation and compliance focus position it as a transformative player in construction tech and safety engineering[3][5][6].
Semble AI was founded in 2025 by Ethan Boyers and Jonathan Tyshler, both Stanford computer science graduates with deep industry experience. Jonathan worked at Convergint, a major fire and security-system design firm, witnessing the inefficiencies in manual system design. Ethan’s personal experience with a house fire in 2017 fueled his passion for fire-tech innovation. Together, they created Semble AI to revolutionize building-system design by leveraging AI to automate workflows that previously took hundreds of hours, making the process faster, more accurate, and fully code-compliant[5].
Semble AI rides the trend of AI automation in traditionally manual, compliance-heavy industries like construction and safety engineering. The timing is critical as the construction sector increasingly adopts digital tools to improve efficiency and reduce costs amid labor shortages and regulatory complexity. By automating fire and life-safety system design, Semble AI addresses a niche with high stakes—building safety and regulatory compliance—while accelerating project timelines. This innovation supports broader ecosystem shifts toward AI-driven operational efficiency and digital transformation in construction tech, potentially setting new standards for safety system engineering[5][6].
Looking ahead, Semble AI is poised to expand its impact by deepening integrations with construction workflows and scaling adoption among system integrators and contractors. Trends such as increasing regulatory scrutiny, demand for faster project delivery, and AI adoption in construction will shape its growth trajectory. As the platform matures, Semble AI could influence industry norms around automated compliance and design, potentially extending into other building systems beyond fire and life safety. Its founders’ strong domain expertise and Y Combinator backing provide a solid foundation for scaling and innovation in this critical infrastructure segment[3][5][6].
