Cerebrium, a startup developing serverless infrastructure for multimodal AI, has raised $8.5 million in seed funding to scale its operations and meet growing enterprise demand. The round was led by Gradient Ventures, Google’s AI-focused venture capital arm, with participation from Y Combinator and Authentic Ventures.
Founded in Cape Town in 2021 by South Africans Michael Louis and Jonathan Irwin, and now headquartered in New York, Cerebrium has built a serverless platform designed to make it easier for developers to deploy real-time AI applications that work across text, images, audio, and video. The startup says it already serves paying customers with high-performance needs — including video personalization company Tavus and voice AI platform Deepgram — despite running on a lean team of just four engineers.
From Cape Town to Silicon Valley
Cerebrium’s roots trace back to Louis’ earlier venture, OneCart, a South African e-commerce company acquired by Massmart, the Walmart-owned retailer. While building AI features for OneCart, Louis encountered the kinds of infrastructure limitations that many engineers face today: provisioning GPU resources, managing inference workloads, and scaling models across environments.
Those pain points became the basis for Cerebrium, which officially launched out of Cape Town before relocating to the U.S. to be closer to customers and investors. The company joined Y Combinator in early 2023 and has since gained traction with developers looking to build high-performance AI without managing backend complexity.
Cerebrium’s core product allows developers to spin up compute resources — both CPUs and GPUs — on demand, paying only for what they use. This model is well-suited for AI applications that require flexible, elastic infrastructure but cannot afford idle costs or long provisioning delays.
“Specialized infrastructure that scales elastically will be essential as real-time AI becomes core to customer experiences,” said Gradient Ventures partner Eylul Kayin, commenting on the firm’s decision to back the startup. Cerebrium’s ability to power diverse AI workloads, from healthcare diagnostics to lifelike avatars and voice agents, positions it at the intersection of multiple AI trends.
The platform also supports containerized deployment, giving teams more control over their model inference environments. According to the startup, this architecture makes Cerebrium ideal for enterprises seeking performance, speed, and scalability without hiring a dedicated infrastructure team.
Riding the AI Investment Wave
Cerebrium’s funding comes amid a record-breaking year for AI startups. Global investment into the space crossed $84 billion in 2024, according to PitchBook, with venture capitalists increasingly backing companies that provide foundational tools for building and scaling AI applications.
While some startups — like StackAI and Artisan — focus on building the next generation of autonomous agents, Cerebrium is betting on the infrastructure layer that enables those agents to run efficiently. By abstracting away backend challenges, the company hopes to become the go-to infrastructure provider for teams building production-ready AI.
The newly raised capital will be used to expand Cerebrium’s engineering team, build new features, and support its growing U.S. customer base. The company also plans to expand geographically and deepen its integrations with enterprise workflows.
Cerebrium is part of a growing cohort of African-founded startups that are going global early, bypassing traditional regional scaling routes in favour of building for international markets from day one. Its trajectory echoes broader trends in African tech, where founders are increasingly launching ventures with both global relevance and local insight.
“Cerebrium’s origin story proves that world-class AI companies can be built from anywhere,” said Louis. “We’re focused on giving developers the infrastructure they need to build truly transformative AI experiences — without the pain of managing the backend.”
With a product already generating millions in annual recurring revenue (ARR) and new backing from top-tier VCs, Cerebrium is well-positioned to become a critical enabler in the next phase of AI development — one where real-time, multimodal intelligence becomes standard across industries.
