Cambio did not arrive with a demo deck and a promise. It arrived with receipts from a business that moves trillions while still thinking in PDFs. Founded in 2022 by Leia de Guzman and Stephanie Grayson, roommates turned investors while earning their master’s degrees at Stanford University, the San Francisco headquartered company came out of stealth on January 22, 2026, announcing an $18 million Series A and a public launch that felt less like a debut and more like a floor report.
Commercial real estate is a $20 trillion industry where capital decisions still crawl through spreadsheets, scanned audits, and weeks of manual review. Buildings generate roughly 40 percent of global carbon emissions, and more than half of Fortune 500 companies have climate pledges they now have to defend. Cambio exists in that pressure gap, applying large language models and agentic AI to turn unstructured building data into investment grade decisions and compliance outputs that actually move capital.
The Series A, led by Maverick Ventures at a $100 million post money valuation, brought participation from Y Combinator, Adverb Ventures, and Peterson Ventures, alongside angels from Procore, OpenAI, Anthropic, Vanta, Vercel, ServiceNow, Notion, and Amplitude. Ryan Isono of Maverick Ventures pointed to founder market fit and an architecture built AI native from the start, not cosmetic automation layered onto old workflows.
That founder market fit is hard to fake. Leia de Guzman previously executed roughly C$8 billion in transactions at Oxford Properties Group across Europe and Asia Pacific and worked in climate investing and federal energy projects before that. Stephanie Grayson held roles at Goldman Sachs, KKR, JPMorgan, Atomic, and Engine No. 1, and wrote her Stanford thesis on commercializing AI for mass retrofit adoption. This is lived pain, not academic curiosity.
Under the hood, Chief Technology Officer Leon Chen, formerly an early engineer at Faire, built a system that ingests thousands of pages of PDFs, utility bills, audits, and filings, normalizes the mess, and reasons across portfolios in minutes. The platform prioritizes retrofits, ranks capital allocation, and automates reporting for frameworks like GRESB, TCFD, SFDR, and Energy Star. SOC 2 Type I compliance was locked in back in 2023, because institutions do not play around.
Traction followed quietly. Cambio supports portfolios across more than 35 countries and over 2 billion square feet, with customers including Principal Real Estate, Nuveen Real Estate, BGO, LaSalle Investment Management, Oxford Properties Group, Madison International Realty, and Beacon Capital Partners. Jennifer McConkey of Principal Real Estate has been explicit about using Cambio’s AI to drive decarbonization decisions that still meet return thresholds.
The $18 million will scale engineering, deepen AI native workflows, and expand internationally from London across Europe and Asia Pacific. Cambio is not selling software. It is selling time back to investors who are tired of guessing with bad data while the clock on carbon and capital keeps ticking, and the next move now sits with anyone still deciding how long spreadsheets can hold the line.
