Investing in Together AI
We are pleased to announce our investment in Together AI, one of the most critical companies to emerge in the current age of AI. Enterprises are rapidly adopting open-source solutions to innovate faster and stay competitive, driving a fundamental shift in how AI is built, deployed, and scaled. Together AI’s full-stack AI acceleration cloud is an active driver of this transformation, empowering customers to address the complex and rapidly evolving demands of generative AI.
At the time of our initial investment in Together AI, we distilled years of insights and interviews with enterprise AI leaders, industry practitioners and private company builders into four key themes defining the state of AI infrastructure software. When we met Vipul Ved Prakash and his team, we quickly recognized Together as a standout in the AI infrastructure space and poised to capitalize on the themes below:
- $1T TAM Expansion via Generative AI – Enterprises are accelerating investments in AI, with open-source models and infrastructure-as-a-service platforms capturing an increasing share of spend.
- Demand for Full-Stack AI Infrastructure – Organizations need integrated AI platforms that provide compute, orchestration, data curation, training, fine-tuning, and inference to maximize performance and efficiency.
- Speed, Scalability & Control as a Requirement – Enterprises demand cost-effective, secure, and transparent AI infrastructure that ensures control over proprietary data and IP.
- World-class AI talent and product roadmap – Together AI is led by a world-class team with the expertise to build, scale, and commercialize a market-leading AI infrastructure platform and ecosystem.
These tenets have only become more evident with time. Together AI’s relentless execution and rapid platform expansion have reinforced its leadership, culminating in a landmark $305M Series B to fuel the next phase of growth. Below, we explore the market forces driving this shift, Together AI’s unique position, and why we believe this company is defining the future of AI infrastructure.
A Massive Opportunity in AI Infrastructure
Generative AI represents the largest TAM expansion of AI software and hardware in decades— it is expected to attract nearly $1 trillion of spend by 2027, with infrastructure spend on AI workloads (training, fine-tuning, inference) projected to reach $400 billion. As the complexity of AI workflows increases—particularly in inference and reasoning applications and agentic systems—the need for scalable yet efficient infrastructure becomes more pressing for enterprises and AI startups alike.
As companies move beyond experimentation into scaled deployments, there is a simultaneous, growing demand among enterprises for AI infrastructure that meets specific business needs while balancing governance, compliance, and operational requirements. Organizations are increasingly seeking AI ecosystems that offer autonomy and adaptability without compromising security or regulatory alignment. This global shift provides strong tailwinds for AI infrastructure that enables customization while maintaining flexibility and control.
Together AI’s open-source approach directly responds to these market shifts. By providing organizations with flexible, efficient, and controlled AI deployments, Together AI unlocks the full potential of generative AI while addressing key strategic concerns, including data sovereignty and security.
Differentiation Through Innovation and Integration
At the heart of Together AI’s success is its innovative, full-stack approach to AI infrastructure. The platform seamlessly integrates every critical element of the AI lifecycle, including compute, orchestration, data curation, training, fine-tuning, and inference. This comprehensive approach enables enterprises to efficiently manage their AI workloads while achieving maximum return on investment.
What sets Together AI apart is the company’s ability to deliver compute-accelerated AI workloads alongside complementary AI systems solutions like Together Inference and Together Fine-tuning. These tools, combined with Together AI’s integration with 200+ generative AI models, empower organizations to build and to deploy AI models at unprecedented speed and scale while significantly reducing costs. Together AI has already delivered measurable impact for its customers, who report tailored AI solutions that outpace traditional and concurrent alternatives in both cost and performance.
The company’s approach to workload management—combining cutting-edge GPU infrastructure with advanced orchestration tools—ensures that customers can optimize their compute investments. Together AI’s differentiated product suite is powered by the company’s best-in-class research team and its internal obsession with offering products on the cutting edge with respect to efficiency, scalability, and transparency. This approach addresses a persistent and growing need for infrastructure solutions that prioritize speed, cost-effectiveness, and control of proprietary data.
