Business Description
Guardrail Mining, Inc. is a Charleston, South Carolina-based Bitcoin mining company founded in 2022 that delivers vertically integrated hash-rate services and operational management, covering site selection and facility design through fleet deployment and chip-level ASIC repair, for private and publicly traded mining operators across North America.
The company's four service lines cover the full mine lifecycle. Under operational management, Guardrail embeds on-site teams to handle logistics, resource allocation, inventory control, and uptime optimization at client facilities. CTO Brett Garman's pre-Guardrail career included roles as diagnostic technician, repair technician, deployment leader, and design consultant at operations running between 20,000 and 76,000 ASIC units, establishing the scale at which Guardrail's teams are designed to operate. Consulting and project management spans mine design, airflow engineering, load distribution, and network and cable architecture. Mine construction takes projects from site selection and permitting through energization. The repair and maintenance line deploys on-site technicians to diagnose and fix faults in next-generation ASICs.
Garman is a six-year U.S. Air Force veteran and former 11-year FAA air traffic controller who began Bitcoin mining in 2017, scaling from a single home ASIC to a 300-unit industrial space. He earned Bitmain AMTC (Antminer Maintenance Training Center) certification in 2018 and again in 2021, and served as lead instructor for Bitmain's inaugural U.S. AMTC S19 course that year, a credential that directly underpins Guardrail's on-site repair and training capability. CEO Joe Angello, a UC Berkeley Economics graduate, brings over 30 years of leadership across international trade, distribution, logistics, and warehousing; he joined Guardrail in 2022 focusing on business development and client partnerships and has been a Bitcoin advocate since 2018.
Guardrail's field teams (which include operations managers and Tier 1 operations specialists per ZoomInfo) are active at facilities for both private operators and publicly traded miners throughout North America. The company's client base, as described publicly, encompasses publicly traded mining companies and large family office investors, though specific customer names have not been disclosed. Guardrail Mining operates within Guardrail Group, a privately held management and holding company that also oversees labor and security businesses serving high-value field environments.
The company employs between 11 and 50 staff and actively recruits Bitcoin mining contractors with on-the-job training. Guardrail's managed hash-rate services model, providing operational management without owning mining infrastructure outright, positions it as an outsourced operator for fleet owners seeking to reduce overhead as the North American mining industry consolidates around larger, professionally managed sites.
