About us

MangoBoost, Inc.

• MangoBoost is a start-up company that develops groundbreaking new data processing units (DPUs). MangoBoost’s novel DPUs can be customized and flexibly integrated into server systems to address myriad system overheads and make other devices (such as SSDs, GPUs, NICs, etc.) smarter. As a result, MangoBoost DPU offers a dramatic boost in system efficiency, performance, scalability, and cost-effectiveness. MangoBoost leverages ~10 years of prior world-leading research done in academia, which has produced extensive full-system patent-pending prototypes published at premier conferences in computer architecture and systems areas (for example ISCA and OSDI). MangoBoost has received a $10M seed fund in 2022 and a $55M Series A fund in 2023 and is actively growing in the US and Korea.
• MangoBoost is comprised of the world's top computer system developers. The founder is currently one of the world's leading computer system architects, and other members are also experts with outstanding careers in various aspects of computer system development. Most team members have conducted research and worked at top-tier universities and companies worldwide. Since 2014, our team has been developing the world's top-level DPU, and we are the only start-up capable of designing a DPU that can compete immediately with giants like Amazon and NVIDIA.
