What Seaborn Networks does
Seaborn Networks is a privately held wholesale carrier specializing in submarine fiber optic cable services connecting the United States to Brazil and other Latin American markets. The company owns and operates the Seabras-1 and AMX-1 submarine cable systems, plus 100% buried terrestrial backhaul in Brazil, cable landing stations, and a network of points of presence (PoPs) — currently 19 PoPs across 8 Brazilian markets plus US presence at Secaucus (Equinix NY2/NY4/NY5/NY6) and Carteret, New Jersey. Seaborn's autonomous system (AS13786) is ranked among the Top 50 globally and the company is ranked Top 19 Global ISP by CAIDA. The parent entity is Seabras Group LLC, a portfolio company of private equity firm Partners Group, with wholly-owned operating subsidiaries Seabras 1 USA LLC and Seabras 1 Brasil Ltda.
Seaborn generates revenue through subscription-based wholesale services delivered to ISPs, telecom operators, content providers, and financial institutions. Its product portfolio is anchored by four core connectivity services: Ultra-Low Latency SeaSpeed™ (offering deterministic three-tier latency between New Jersey and B3 São Paulo at 105.08ms / 106.05ms / 106.54ms), Wavelengths (1Gb/10Gb/100Gb capacity), MEF-compliant Carrier Ethernet, and IP Transit. These are supplemented by value-added services including Anti-DDoS protection (launched 2026), Enterprise Direct Internet Access, and Remote Peering/Cloud Connect, as well as Network Design & Consulting and Network Managed Services. SeaSpeed is homologated by B3 (Brazilian Stock Exchange) as an RCB network provider, giving Seaborn a regulated foothold in Brazilian financial market connectivity. The company is differentiated by being the only independent submarine cable operator that owns its full submarine-to-PoP stack.
Seaborn distributes services through direct enterprise sales with technical consultants, inside sales for mid-market customers, and partner/vendor referral networks. Marketing is concentrated around major wholesale telecom industry events (PTC'26, Metro Connect 2026, Capacity Latam 2026, ITW 2026), an English/Portuguese website, mailing list outreach, and press coverage of partnerships and expansions. Pricing is opaque and quote-based across all services. Named customers include Ascenty (data centers), Orchest Technologies (telecommunications), Webby Internet (ISP), and B3 (financial exchange). Headcount is reported at 11–50 employees, consistent with a lean wholesale carrier operating model.

Seaborn Networks competitors and assessment
Company assessmentDirect peers
- Sparkle: TIM Group's international wholesale carrier, Sparkle operates a global subsea and terrestrial IP network offering IP Transit, wavelengths, and capacity services to carriers and content providers. Comparable in product mix, target customer base, and global wholesale carrier positioning.
- GlobeNet: GlobeNet operates subsea cable systems connecting the US to Brazil (and onward to Colombia/Venezuela), offering wholesale wavelength, IP transit, and Ethernet services. It is the closest direct competitor to Seaborn on the US-Brazil corridor with overlapping product sets and customer segments.
- Liberty Networks: Liberty Networks (part of Liberty Latin America) operates subsea capacity in the Caribbean and Central America serving wholesale carrier and enterprise customers. It overlaps with Seaborn's Latin American wholesale carrier footprint and target customer base, particularly for content and ISP traffic.
- Aqua Comms: Aqua Comms owns and operates subsea cable systems including AEConnect (US-Ireland) and Havfrue/AEC-2, selling wholesale wavelengths, spectrum, and managed services to carriers and content providers. It mirrors Seaborn's owned-asset, wholesale-only business model with a focus on long-haul trans-Atlantic capacity.
- EXA Infrastructure: EXA Infrastructure (formerly Hibernia Networks' cable assets) operates trans-Atlantic low-latency subsea cables historically focused on financial services connectivity. Its route engineering, ultra-low-latency product mix, and wholesale carrier focus closely parallel Seaborn's SeaSpeed and wholesale wavelength strategy.
- Telxius: Telefónica's infrastructure subsidiary operating the BRUSA subsea cable connecting Brazil to the US, plus Marea and Dunant. Telxius sells wholesale capacity and IP services into the same US-Brazil corridor and adjacent Latin American markets, making it a directly comparable subsea wholesale competitor.
- EllaLink: EllaLink operates a dedicated subsea cable between Brazil (Fortaleza/São Paulo) and Europe (Sines/Marseille), targeting low-latency trans-Atlantic data and research traffic. While its geography is Brazil-Europe rather than US-Brazil, it is a directly comparable independent subsea cable owner-operator with similar product positioning.
Broad incumbents
- Zayo Group: Zayo operates one of North America's largest fiber networks plus long-haul routes, offering wavelengths, Ethernet, IP, and managed services to carriers and enterprises. It is a broader incumbent with overlapping wholesale wavelength and IP products, though less focused on US-Brazil subsea.
- Lumen Technologies: Lumen is a large global carrier offering wavelengths, IP, Ethernet, and managed services across an extensive owned fiber footprint. It overlaps with Seaborn's wholesale carrier products and serves similar ISP, content, and enterprise customers, though its infrastructure is terrestrial-heavy and globally diversified.
Emerging players
- Hurricane Electric: Hurricane Electric operates a large global IPv6-native backbone and is among the top-ranked global ISPs, offering IP transit and remote peering. Comparable to Seaborn's AS13786 IP Transit business in target customer base (ISPs, content providers) and AS ranking positioning.
