Sielo is a technology company.
Sielo provides an Internet of Things (IoT) platform to modernize commercial buildings. Its LEDSENSE IoT Platform integrates smart, wireless LED technology with cloud connectivity, delivering comprehensive building intelligence. This system transforms existing infrastructure into efficient environments by unifying power, light, and data management for commercial applications.
Founded in 2003 as Terralux in Boulder, Colorado, the company initially focused on LED retrofit lighting. Recognizing the industry's shift towards connected spaces, Terralux rebranded as Sielo. This strategic move leveraged its lighting expertise to address the rising demand for intelligent building management systems.
Sielo serves commercial retrofit and OEM sectors, offering solutions that convert traditional spaces into intelligent, data-driven environments. The company envisions fostering sustainable and intelligent buildings through robust, cloud-based offerings. It aims to equip building operators with superior control and insights for optimal efficiency and responsiveness.
Sielo has raised $17.0M across 2 funding rounds.

Sielo is a Boulder, Colorado-based technology company (formerly Terralux) that designs and manufactures LED lighting solutions and building intelligence systems, with a focus on its LEDSENSE® IoT platform for connected buildings.[1][2] It serves commercial sectors including university campuses, medical facilities, offices, municipal buildings, multifamily housing, hospitality, education, retail, and OEM fixtures, solving problems of inefficiency in building management by integrating power, light, and data via existing infrastructure to boost efficiency, sustainability, productivity, and occupant well-being.[1][2] The company reports annual revenue around $4.6–$6.9 million, has raised approximately $53 million in funding across 9 rounds, and employs 16–63 people, showing steady operation since 2003 with implementations across U.S. building projects.[2][3]
Founded in 2003 in Boulder, Colorado (now headquartered in Longmont), Sielo began as Terralux, specializing in LED solutions and building intelligence.[1][2] In 2017, it rebranded to Sielo—derived from "sky," symbolizing connected lighting and IoT—and accelerated its LEDSENSE platform, expanding capabilities for end-users and certified partners with a summer software release that enhanced controls for diverse commercial spaces.[1] Key figures include CEO Steve Hane, who emphasized evolving commercial building needs, and Matthew Sallee, Director of Strategic Marketing; Chris White serves as Director of Engineering.[1][2] This evolution marked a pivot from pure LED manufacturing to cloud-based IoT for intelligent buildings, leveraging 20+ years of expertise amid rising demand for smart facilities.[1][2]
(Note: A separate Canadian entity, Sielo Robotics, develops wheelchair-mounted robotic arms but is distinct from this U.S. lighting/IoT firm.[4])
Sielo rides the commercial IoT and smart buildings trend, capitalizing on the shift toward energy-efficient, data-driven facilities amid rising sustainability mandates and post-pandemic focus on occupant health/productivity.[1] Timing aligns with maturing LED adoption and IoT growth, where existing infrastructure retrofits reduce barriers to entry versus new builds—key as commercial real estate faces efficiency pressures from regulations and operational costs.[1][2] Market forces like cloud integration and edge computing favor Sielo's model, influencing the ecosystem by enabling facility managers (e.g., via partners like ABM) to achieve "intelligent sustainability" without massive capex, thus accelerating IoT in non-residential buildings.[1]
Sielo is positioned to expand LEDSENSE amid surging demand for net-zero buildings and AI-enhanced IoT, potentially growing via partnerships and international retrofits as funding ($53M raised) fuels R&D.[2][3] Trends like edge AI for real-time occupancy analytics and ESG compliance will shape its path, evolving its influence from lighting specialist to full building intelligence leader—building on its 20-year foundation to capture more of the $100B+ smart building market. This cements Sielo's role in practical, connected infrastructure for tomorrow's facilities.[1][2]
