In a significant development, Together AI, a leading developer of cloud platforms for artificial intelligence, has seen its valuation rise to $3.3 billion after securing a $305 million series B funding round which was led by General Catalyst and Saudi Arabia’s Prosperity7Ventures. This led to a remarkable jump of the company’s valuation by 160% from its previous valuation of $1.25 billion.
Together AI was founded in June 2022 by Vipul Ved Prakash (CEO), Ce Zhang (CTO), Percy Liang and Chris Re. The company was created with the aim of leading open-source research, models and datasets to advance the frontier of AI. Its decentralized cloud services empowers developers and researchers at all levels of organization to train, fine-tune and deploy generative AI models.
Together AI connects its users to high-end GPU (Graphics Processing Unit) to facilitate its decentralized platform. The platform allows its users to run open-source AI models without relying on traditional cloud services. Its open-source platform provides services and models that enable its users to incorporate AI into their applications.
Together AI had its first valuation of $500 million in November 2023, led by Kleiner Perkins with participation from NVIDIA and Emergence Capital, during which it raised $102.5 million in funding. The company had another $1.25 billion valuation led by Salesforce ventures in partnership with Coatue, Lux Capital and Emergence Capital in March 2024 where it raised $106 million in funding.
Its recent funding, which put the company at a valuation of $3.3 billion is driven by the need to expand the company’s AI Acceleration Cloud that aids developers and businesses train, run inference and fine-tune generative AI models for their apps. This will help the company’s goal of being the preferred AI Cloud for building modern AI applications with open-source models in the global market.
Since 2022, Together AI’s Acceleration Cloud has served as a transformative tool for over 450,000 AI developers, AI-native companies and global enterprises like Salesforce, Zoom, SK Telecom, Hedra, Cognition, Zomato, Krea, Cartesia, and The Washington Post in building modern AI applications.
Together AI’ platform accelerates the adoption of open-source AI by individuals and businesses alike, by providing optimized inference for AI models like Llama and DeepSeek-R1. Coupled with a full-stack AI Acceleration cloud that trains and fine-tunes frontier foundational models, aids synthetic data generation, its platform guarantees security, accuracy, performance and model ownership for its users.
Together AI’s AI Acceleration Cloud currently supports over 200 open source models across all data types like chat, image, vision, audio, code and embedding. Powered by its custom-built engine and cutting-edge technology like FlashAttentio-3 kernels and advanced quantization techniques, the cloud is able to deliver faster interference, which is 2-3 times higher than standard cloud services.
Together AI is currently undergoing an infrastructural expansion to meet the demands of its growing ecosystem. Recognizing a crucial need for higher computational power, the company secured 200MW of power capacity and is actively deploying optimized clusters of NVIDIA Blackwell GPU’s across North American data centers.
With a pivotal partnership with Hypertech to co-build a cluster of 36,000 NVIDIA GB200 NVL72 GPUs, Together AI strengthens its position as a leading AI Cloud provider. Together AI consistently pushes the boundaries of AI and system optimization which led to innovations like Medusa, Sequoia, Mixture of Agents, Hyena and Mamba. Its Together Kernel collection, achieved a 24% boost in training operations whilst simultaneously reducing costs for customers.
These advancements achieved by Together AI, is not only driven by AI accuracy, performance and efficiency, but also by accessibility on a global scale by companies and developers whilst being cost effective.
