Centinel

What Centinel does

Centinel (formerly Carbon Lighthouse), founded in 2010 and headquartered in San Francisco, provides AI-driven energy-efficiency and decarbonization solutions for commercial real estate. The company's core platform, CLUES (Carbon Lighthouse Efficiency Optimization System), analyzes 15-minute interval building data alongside HVAC and lighting telemetry to detect faults, optimize operations, and reduce energy spend. The stack combines proprietary analytics with hardware retrofitting and is integrated with ENERGY STAR benchmarking, with infrastructure hosted in partnership with AWS.

Centinel serves 50+ commercial real estate firms managing $1.5 trillion+ in assets across 2,000+ buildings in 46 U.S. states. Named customers include public REITs (Ventas, Welltower, American Healthcare REIT), institutional asset managers (Goldman Sachs, Blackstone), brokerages (JLL, Newmark), and operators spanning healthcare, hospitality, multifamily, retail, industrial, and education assets. Disclosed impact includes $500M+ in delivered net asset value, $97M in tenant savings, and $10M/yr in landlord rebates under the Monetize program.

Revenue is generated through three primary streams: a $299/month subscription to the Discover & Save optimization tier, fixed monthly service fees starting at $250/month plus one-time hardware installation, and the Monetize infrastructure-lease program under which Centinel funds and owns on-site upgrades in exchange for a share of savings via 10-year agreements that return $20k-$60k per building per year to participating landlords. The company has raised ~$67M+ in disclosed venture funding, including a 2024 $27M growth round and a 2019 $32.6M round led by Cox Enterprises.

Directly comparable to Centinel because it serves the same REIT and institutional CRE customer base, focuses on utility/asset benchmarking, and uses benchmarked data to drive decarbonization decisions rather than capex projects.
• Bright Power: Provider of building energy analytics, benchmarking, and project development services for multifamily and commercial portfolios. Comparable to Centinel in delivering energy audits, project identification, and implementation support across HVAC, lighting, and envelope categories for CRE owners.
• 75F: Cloud-based predictive HVAC and building automation platform using IoT sensors and ML to optimize commercial building performance in real time. Comparable to Centinel's CLUES platform because both ingest sensor data at frequent intervals, apply ML to find savings, and target mid-market commercial portfolios.
• Switch Automation: Building analytics software for CRE portfolios that integrates BMS data, tracks energy use, and flags operational issues. Directly comparable to Centinel Insight/Discover & Save in serving portfolio-level energy analytics for CRE owners and operators.
• GridPoint: Energy management and optimization platform combining on-site controls, submetering, and analytics for commercial buildings and small-box retail. Comparable to Centinel because it monetizes building-level energy data through both hardware and recurring SaaS targeting multi-site CRE.

Broad incumbents

• Iconics (a Mitsubishi Electric group company): Long-established industrial and building IoT analytics suite with fault detection and visualization capabilities. Comparable as a broad incumbent offering overlap with Centinel's CLUES FDD and analytics functions, bundled within larger building/industrial automation portfolios.
• Honeywell Building Technologies: Division of Honeywell that sells BMS, energy analytics, FDD, and HVAC services at global scale. Broad incumbent operating in the same building optimization space as Centinel but with much wider product breadth and entrenched relationships among large CRE owner/operators.
• Johnson Controls (OpenBlue): Global building technology provider with the OpenBlue digital platform covering FDD, energy optimization, and connected equipment. Comparable to Centinel as a broad incumbent with overlapping FDD and tenant-billing analytics capabilities sold into the same REIT/PE customer base.

Emerging players

• Verdigris Technologies: AI-powered energy monitoring platform with hardware sensors and analytics targeting mid-market commercial and industrial facilities. Comparable to Centinel on the fault detection and predictive analytics axis, but smaller scale and narrower geographic footprint.
• Infogrid: Full-stack smart building platform combining IoT sensors, AI analytics, and BMS integration for CRE portfolios. Comparable to Centinel on the technology stack (continuous monitoring, anomaly detection, ESG reporting) but operates primarily in the UK and EU rather than US.
