Arch Capital and HMC Capital complete first close for Brazil data center platform

Arch Capital and HMC Capital have closed the first round of funding for Twenty Four Seven Data Centers, a Brazilian hyperscale data center platform focused on next-generation digital infrastructure. The deal brings in international and local institutional capital as Brazil faces a shortage of high-capacity data center assets.

Why it matters: - Twenty Four Seven Data Centers is aiming to become one of Brazil’s leading independent hyperscale data center operators. - The funding supports a market where demand for high-capacity digital infrastructure is rising and supply remains short. - The platform has control of strategically located land plots and access to more than 150 MW of energy capacity, which can help it pursue hyperscaler clients.

What happened: - Arch Capital and HMC Capital announced the first close of the investment program for Twenty Four Seven Data Centers on August 3, 2026, in São Paulo. - The capital raise was anchored by Just Climate and Kinea Investimentos. - The round also included Brazilian multi- and single-family offices, including G5 Partners, Ekho Family Office, and One, through a transaction-specific vehicle. - HMC Capital acted as capital advisor and connected Arch Capital with institutional investors and family offices.

The details: - Twenty Four Seven Data Centers is a Brazilian platform focused on the development, construction and operation of next-generation hyperscale data centers. - The company is focused on energy efficiency, scale and compliance with technical standards required by global hyperscalers. - Just Climate is an investment manager established by Generation Investment Management and focused on scaling solutions for emissions-intensive sectors and those furthest from global climate targets. - Kinea Investimentos is one of Brazil’s leading asset managers and an affiliate of Itaú. - HMC Capital has US$27 billion in assets under management and distribution across Latin America. - Arch Capital was founded in 2007 and says it has built a track record over nearly two decades in real asset investments in Brazil. - The Arch Capital technical team has experience developing, constructing and operating hundreds of megawatts of data center capacity across Latin America. - Guilherme Sousa, HMC’s partner, said the investor lineup reflects a strong investment thesis in a segment where Brazil has competitive advantages.

Between the lines: - The investor mix suggests the deal is being positioned as both an infrastructure play and a climate-aligned investment. - Brazil’s scarcity of assets that meet hyperscaler technical requirements creates an opening for operators with land, power and execution capability. - HMC’s role shows continued institutional appetite for alternative investments in the region.

What’s next: - Twenty Four Seven Data Centers will use the new capital alongside ongoing commercial and infrastructure progress to expand its position in Brazil. - The company is positioned to compete for hyperscaler partnerships as it develops its pipeline and infrastructure footprint. - Arch Capital and HMC Capital may seek additional investment rounds as the platform scales, though no further timeline was announced.

The bottom line: - The first close gives Twenty Four Seven Data Centers institutional backing, power access and land control at a time when Brazil’s hyperscale data center market is still undersupplied.
