Somos Internet, a vertically integrated fiber provider based in Medellin, Colombia, has closed a $40 million Series B round co-led by Bracket Capital and Ribbit Capital. The round also drew participation from Union Square Ventures, Kaszek Ventures, Not Boring Capital, Zero Infinity Partners, and Y Combinator.
The new capital will fund a major expansion of Somos's fiber network across Colombia and finance the company's entry into Mexico City, its first market outside its home country.
As AI tools move from corporate data centers into everyday products and services, the quality of internet infrastructure has become a defining variable in how quickly that transition happens. In Latin America, where traditional providers have long charged premium prices for mediocre service, that gap is especially wide.
Somos's position is that AI adoption across the region will stall without abundant, affordable connectivity. The company offers multi-gigabit residential fiber plans starting at $15 per month with no contracts, enterprise plans reaching up to 100 Gbps, and customer service powered by AI-supported human agents. Enterprise clients already on the network include Mercado Libre and Rappi.
"If compute is the brain of the AI era, connectivity is the nervous system," the company said in its announcement. "High-capacity, low-latency fiber is foundational infrastructure for unlocking AI potential across Latin America."
Somos will use the Series B proceeds to more than triple its serviceable footprint in Colombia while launching operations in Mexico City. The company projects continued acceleration through 2026 as both expansions gain traction.
A significant portion of the capital will also go toward FiberX, the company's proprietary data center-inspired network architecture. FiberX delivers dedicated fiber connectivity directly to each home or business, scales from 1 Gbps to 100 Gbps through simple module swaps, and uses dual fiber links for built-in redundancy.
"This new capital allows the Somos flywheel to approach escape velocity in Colombia and lays the groundwork to repeat the model in Mexico," said CEO Forrest Heath. "This gives us an unfair advantage, and we expect to become the largest internet provider wherever we offer our service."
Founded in 2021 in Medellin's underserved hillside neighborhoods, Somos Internet has grown into Colombia's fastest-growing fiber ISP and the city's third-largest provider in just four years. The company now employs over 1,000 people, the majority of them engineers. Revenue tripled in 2025, and user numbers more than doubled year over year.
What separates Somos from incumbents is full control over every layer of its stack. The company builds its own active Ethernet network topology, manufactures its Orb routers in-house, and runs custom network management software. That vertical integration produces a cost structure that improves as the network scales, with dedicated bandwidth per customer rather than shared connections. The company operates with no contract lock-ins and transparent pricing throughout.
The investor lineup reflects confidence not just in the core fiber business but in the broader platform Somos is building. Packy McCormick of Not Boring Capital framed it directly.
"The really exciting thing about Somos is that their vertical integration unlocks so many different paths for growth," McCormick said. "Everything from selling networking solutions to hyperscalers in Latin American data centers to hardware and digital product offerings to existing users. Their infrastructure capabilities open doors to adjacent industries."
The round builds on backing from a mix of Silicon Valley and Latin American investors who have supported the company since its founding. Investors include Bracket Capital, Ribbit Capital, Union Square Ventures, Kaszek Ventures, Not Boring Capital, Zero Infinity Partners, and Y Combinator.
