What Atherton Fiber does
Atherton Fiber was a privately held fiber-to-the-home (FTTH) internet service provider founded in 2015 and headquartered in San Francisco, California, serving the affluent residential community of Atherton in the San Francisco Bay Area. The company operated 11-50 employees and delivered ultra-fast 10 gigabit fiber internet connectivity directly to homes, schools, and public environments via its owned fiber infrastructure. Its core technical offering was symmetric 10 Gbps service delivered over a 100% fiber network, with no disclosed pricing but a residential and small-business go-to-market typical of community FTTH operators.
In August 2025, Atherton Fiber was acquired by Race Communications, a portfolio company of private equity firm Oak Hill and described as California's largest privately held 100% fiber-to-the-home provider. The transaction integrated Atherton Fiber's installed fiber footprint, customer base, and brand into Race's broader California network, with the deal completed following initial regulatory review. Race's positioning emphasizes transparent pricing, no early termination fees, no sudden price increases, unlimited data, free installation, and local support, alongside add-on home phone service at $10/month.
Post-acquisition, Atherton Fiber operates as an integrated brand within Race Communications' portfolio. Race has signaled accelerated California-wide FTTH expansion across San Joaquin Valley, Sacramento Valley, San Diego County, and Southern California, backed by cumulative investments exceeding $650 million. The Atherton asset functions as a high-AUP (average revenue per user) foothold in the Bay Area and a beachhead for the parent platform's broader growth strategy.

Atherton Fiber competitors and assessment
Company assessmentBroad incumbents
- Lumen Technologies: Lumen (formerly CenturyLink) operates a large fiber and wireline network providing enterprise and wholesale connectivity, and is expanding residential fiber via Quantum Fiber. It is comparable as a wired telecom operator offering fiber broadband, though at national scale and with broader portfolio.
- Google Fiber: Google Fiber is a large, well-capitalized fiber ISP offering gigabit and multi-gig residential service in select U.S. cities. It competes on the same FTTH product category as Atherton Fiber and is a benchmark for premium fiber brand positioning.
- Comcast Xfinity: Xfinity is Comcast's consumer cable and fiber broadband brand and the dominant incumbent broadband provider across much of California. Race's competitive page explicitly benchmarks against Xfinity, making it the primary incumbent cable competitor to Atherton Fiber.
- Frontier Communications: Frontier is a national fiber-to-the-home and copper broadband provider aggressively expanding its fiber footprint. It is comparable to Atherton Fiber as a FTTH operator selling multi-gig residential broadband, though at materially larger scale and broader geography.
- AT&T Fiber: AT&T Fiber is the FTTH arm of AT&T, offering multi-gig residential internet across major U.S. metros including California. It is the incumbent telecom competitor explicitly benchmarked against Race/Atherton Fiber and competes in the same Bay Area FTTH category at massive scale.
Direct peers
- Sonic (Sonic.net): Sonic is a California-based independent fiber ISP offering gigabit and multi-gig residential service in parts of the Bay Area and Northern California. It is a direct competitor to Atherton Fiber in overlapping Bay Area geographies and customer segments.
- Race Communications: Race Communications is the parent company of Atherton Fiber and itself a 100% fiber-to-the-home provider across California offering up to 10 Gbps residential and business service. It is the most directly comparable operator in the same geography, target customer, and product category.
- Ting Internet: Ting Internet is a fiber-to-the-home ISP (a Tucows company) deploying gigabit and multi-gig service in select U.S. towns and suburbs. It is comparable as a niche, fiber-pure residential ISP with a similar target market of homeowners in smaller markets.
- Ziply Fiber: Ziply Fiber is a regional fiber ISP operating across the Pacific Northwest with multi-gig residential plans. It is comparable to Atherton Fiber as a smaller, fiber-pure operator with PE backing and a focus on displacing legacy cable and DSL.
Others
- Crown Castle Fiber: Crown Castle owns and operates large-scale fiber infrastructure across the U.S., including in California, and supplies backhaul and lit/dark fiber to ISPs. It is comparable to Atherton Fiber as a California fiber network operator, though primarily infrastructure/wholesale rather than retail residential ISP.
