Together AI has landed a $305 million Series B funding round, more than doubling its valuation from last year’s $1.25 billion to $3.3 billion. The round was led by General Catalyst and co-led by Prosperity7, the venture capital arm of Saudi Aramco, with participation from a mix of institutional and strategic investors, including NVIDIA, Salesforce Ventures, Kleiner Perkins, and Coatue.
Key Points:
- Together AI raised $305M in Series B, bringing its valuation to $3.3B.
- The company will expand its AI infrastructure, deploying NVIDIA Blackwell GPUs.
- Together AI’s cloud supports over 200 open-source AI models, including Llama and DeepSeek.
- The company has surpassed 450,000 developers and $100M in annualized revenue.
The fresh capital will accelerate the growth of Together AI’s cloud platform, which provides AI developers and enterprises with access to high-performance infrastructure for training and deploying generative AI models. The company plans to scale its AI Acceleration Cloud by deploying NVIDIA’s latest Blackwell GPUs, including a 36,000-GPU cluster of GB200 NVL72 chips, to enhance its AI capabilities.
Founded in 2022, Together AI has quickly gained traction by offering an open-source alternative to proprietary AI platforms. It supports over 200 models, including Meta’s Llama and China’s DeepSeek-R1, and has developed infrastructure optimized for high-speed inference and model training. The company’s platform also enables fine-tuning, agentic workflows, and synthetic data generation, making it a key player in the enterprise AI market.
The funding comes amid a broader surge in AI investments, with venture capital pouring billions into AI infrastructure companies. In Q4 2024 alone, AI startups raised over $42 billion, nearly doubling the previous quarter’s record funding levels. Together AI itself has experienced rapid growth, surpassing 450,000 developers on its platform and generating over $100 million in annualized revenue.
As the company scales its infrastructure and expands its enterprise offerings, it will be worth watching how it navigates the complex balance between rapid growth and maintaining the performance advantages that have fueled its success so far.
