What JSI does
JSI (legally John Staurulakis, LLC) is a privately held US telecommunications consulting and broadband solutions firm founded in 1962 and headquartered in Greenbelt, Maryland. The company serves independent broadband providers, incumbent and competitive local exchange carriers, electric cooperatives, and municipal utilities across all 50 states, with 19 offices and professional engineers licensed in 44 states. Its service portfolio is organized into three lifecycle pillars — Strategy & Design, Network Enablement, and Operate & Scale — covering business planning, capital funding, engineering, permitting, construction management, deployment, regulatory compliance, financial operations, network operations, and customer support.
JSI's technology stack is anchored by a set of proprietary platforms that operationalize its consulting work. Intelli-Fiber is an AI-augmented fiber network design tool that automates up to 90% of the design process; RegPro is a cloud-based regulatory management platform for federal and state filings; Taxient handles tax and exemption management; NOC X provides 24/7 network monitoring; SupportOne runs a 24/7 US-based Tier-1 contact center; VoipEra offers hosted voice; JSInform is a project management framework; and SiteTracker provides real-time construction tracking. The firm also operates a JSI Dashboard/Portal product for client-facing analytics. Collectively these tools have supported over $3.5 billion in grant-funded broadband projects and fiber build-outs whose total length is described as "8x around the Earth."
JSI's revenue model is hybrid: a base of professional services and consulting engagements (project-based and multi-year retainers with telecommunications providers, electric cooperatives, and municipal utilities), supplemented by subscription and licensing revenue from its proprietary technology platforms (RegPro, Taxient, JSInform, NOC X, SupportOne, VoipEra, SiteTracker). Go-to-market is direct enterprise sales and consulting-led, supported by management seminars in Atlanta, Austin, Minneapolis, and Nashville, an e-Lerts newsletter, and content marketing. The firm is controlled by private equity sponsor Stone-Goff Partners, under which it has executed an active roll-up: Mitchell Engineering (2022), Inteserra (2024), LogicomUSA (2025), and prior tuck-ins of N-Com, CSS, and Mid-State Consultants. Leadership is led by CEO David Makuen, CRO Adrian Fitzgerald, COO Michele Friedman, and CFO Brett Madison.
