What Borne Consulting does

Borne Consulting was a privately held, San Francisco-based architectural engineering firm founded in 2021 by Cade D. Osborne, PE. The firm specialized in building envelope solutions for existing buildings, with core technical focus on facades, roofing, balconies, and below-grade waterproofing. It served building owners and property managers in the Bay Area who required specialized expertise for complex building rehabilitation projects.

The company offered a full lifecycle of engineering consulting services spanning condition assessments, construction documentation, permitting support, capital asset planning, bidding coordination, and construction administration. Its value proposition rested on domain specialization in building envelope engineering rather than proprietary technology — the work product consisted of licensed PE deliverables, technical reports, and project oversight. The firm operated with 1-10 employees, served a single regional market (Northern California / Bay Area), and pursued customers via direct B2B enterprise sales targeting building owners and managers.

In August 2025, Borne Consulting was acquired by Milrose Consultants, a national building lifecycle services firm, in a transaction facilitated by Southfield Capital. The acquisition absorbed Borne's architectural engineering and envelope consulting capabilities into Milrose's broader service platform (which spans permitting, code consulting, third-party inspections, facade consulting, drone inspections, and related services across the U.S.), expanding Milrose's Northern California presence. Post-acquisition, Borne operates as a subsidiary of Milrose, and its standalone operations have been integrated into Milrose's national platform. Revenue was not publicly disclosed.
