MangoBoost
|
Data Processing Unit (DPU) is a next-generation server accelerator designed to orchestrate various intra-server devices (e.g., CPU, GPU, SSD, NPU, NIC). By maximizing the datacenter’s overall performance and cost efficiency, DPU is now considered as the most important HW/SW solution to realize the next-generation extreme-scale AI serverinfrastructure. However, despite its critical necessity from the datacenter and AI infrastructure, there is no market-leading DPU solution which can meet the customer’s actual demand due to its HW/SW complexity and the application/model heterogeneity. MangoBoost is currently the world’s most highly recognized DPU startup located in US and Korea. We provide the world’s most advanced and flexible DPU HW/SW solutions in order to fully satisfy the needs of various customers. Our DPU HW is fully composable by integrating its rich set of DPU features to construct our customer-optimal DPUs. At the same time, our DPU SW enables to seamlessly deploy the solution to any customer environment. As a result, our DPU solutions are considered very promising to realize the next-generation AI/datacenter infrastructure, and thus they are currently evaluated at various global-leading companies. MangoBoost was founded in early 2022 to commercialize 7 year of top-tier DPU research outcomes achieved at Seoul National University (e.g., many full-system DPU prototypes, many ISCA/MICRO/ASPLOS/OSDI/ATC papers). The current team consists of 45+ system engineers including ~20 top-tier PhDs from Carnegie Mellon University, Seoul National University, POSTECH, U Toronto, and ~20 industry experts from Intel, Microsoft, Samsung, and Naver. | $6.7M / Series B / Apr 21, 2026 | |

Rebellions
|
AI chip architects are often inattentive to advanced deep learning features and requirements because they believe software stacks between their silicon and algorithms can provide effective abstract layers. We disagree. We do not think such naively designed chips can efficiently utilize expensive custom silicon resources. The more native hardwaresupports are enabled, the higher performance is achieved.Rebellions Inc is building genuine AI accelerators by bi-directionally bridging the gap between underlying silicon architectures and deep learning algorithms. We push algorithm boundaries to better exploit silicon budgets, while re-architecting AI processors to incorporate sophisticated deep learning features through silicon-dedicated DL kernels.Our goal is to deliver a domain-specific AI processor along with its optimized software. This approach, together with our unique decentralized programming model, will enable customers to arm with the most powerful yet energy-efficient AI hardware as well as seamless integration. | $250M / Series C / Sep 30, 2025 | |
