Ideal Customer
- BIG Fiber's sweet spot is enterprise and hyperscale customers with intensive, mission-critical bandwidth needs—specifically data center operators, hyperscalers (large cloud providers), and large enterprises such as technology companies, healthcare systems, and universities operating multi-building or multi-campus environments.
- Named data center partners such as Digital Realty, QTS, EdgeCore, and Flexential suggest their typical customer is a large-scale, multi-facility operator that benefits from high-fiber-count, diverse, low-latency dark fiber.
Key Differentiators
- BIG Fiber's core differentiation is its 100% newly constructed, 100% underground, privately owned and operated dark fiber networks—deliberately engineered to minimize overlap with legacy operator infrastructure, providing true route diversity that older networks cannot match.
- Its high-strand-count, single-mode, low-loss fiber cables and purpose-built metro topologies support extreme route diversity (tri-/quad-versity) and ultra-low latency, which are key for AI-driven workloads and hyperscale data center interconnection.
Industries Served
- BIG Fiber primarily serves the technology, data center, and hyperscaler industries, providing dark fiber connectivity to mission-critical data centers, cloud providers, and large-scale AI-driven workloads.
- Its Corporate Network Solutions also explicitly targets technology businesses, healthcare providers, and colleges/universities needing private, low-latency campus and multi-site connectivity.
Service Coverage
- BIG Fiber operates as a regional U.S. metro dark fiber provider, covering three key markets: the San Francisco Bay Area, Greater Atlanta, and Greater Portland.
- In the San Francisco Bay Area, the network extends to more than 320 route miles and 65 data centers; in Greater Atlanta, it spans more than 330 route miles (with expansion underway to 550+ route miles) and 30 data centers; and in Greater Portland, it covers over 20 route miles and 15 data centers.
Partnerships
- BIG Fiber has established several notable data center and network operator partnerships.
- On the data center side, key named partners include Digital Realty (for Silicon Valley and Atlanta campuses on PlatformDIGITAL®), QTS Realty Trust (Santa Clara), EdgeCore Digital Infrastructure (72MW Silicon Valley campus), and Flexential (Greater Atlanta).
Company Size & Ownership
- BIG Fiber was founded in 2019 (originally as Bandwidth Infrastructure Group / Bandwidth IG) and rebranded to BIG Fiber in May 2025.
- The company is small, with approximately 33–34 employees across offices in Sunnyvale, CA, Atlanta, GA, and Denver, CO.
Compliance & Certifications
- No public documentation of formal compliance certifications such as SOC 2, HIPAA, PCI-DSS, FedRAMP, or ISO 27001 was found for BIG Fiber, which is consistent with its role as a dark fiber infrastructure provider rather than a managed IT or cloud services company.
- A notable environmental distinction is that BIG Fiber originated the first-ever green loan in the dark fiber sector in 2024, structured in alignment with the Loan Market Association's Green Loan Principles, which was subsequently upsized from $90 million to $140 million.
