What O'Brien360 does

O'Brien360 is a Seattle-based sustainability consulting firm serving the built environment, founded in 2016 through the merger of legacy firm O'Brien and Company (established 1991) and 360 Analytics. The firm delivers four integrated service lines — consulting, certification, building performance, and commissioning — to developers, building owners, government agencies, educational institutions, healthcare providers, and affordable housing developers. Its core technical competency is expertise across more than 14 green building rating systems, including LEED (across BD+C, CI, CS, O+M, Homes, and Healthcare variants), Living Building Challenge, WELL, Fitwel, Passive House, Energy Star, Salmon Safe, Built Green, Evergreen Sustainable Development Standard, Envision, and net-zero certifications. The firm positions itself as a project-embedded technical advisor from schematic design through occupancy, providing LEED project management, energy modeling, third-party commissioning, and design review.

The firm generates revenue through project-based professional services engagements, with fees negotiated per project scope and complexity. Its go-to-market is sales-led and referral-driven, relying on direct engagement with project teams, industry awards (USGBC, NAIOP, AIA, AGC, DBIA, ENR, FIABCI), and a deep portfolio of award-winning projects across the Pacific Northwest and select other states. Notable clients include the University of Washington (multi-campus Sustainability Manager role), Google (Lakefront Blocks development in South Lake Union), Kaiser Permanente, the Space Needle (Century Project), Washington State DOT, and DESC. The firm is privately held with no disclosed external funding, no subsidiaries, no M&A activity, and no patents, operating as a small 11–50 employee professional services practice with a regional Pacific Northwest anchor and opportunistic project-driven geographic expansion into California, Alaska, Hawaii, and Massachusetts.
