Top 9 AI Infrastructure Companies & Applications in 2025

Many organizations invest heavily in AI, yet most projects fail to scale. Only 10-20% of AI proofs of concept progress to full deployment.¹

A key reason is that existing systems are not equipped to support the demands of large datasets, real-time processing, or complex machine learning models. Building the right infrastructure is critical as AI becomes more central to business strategy.

Explore the top 9 AI infrastructure companies, their core components, and what is required to support AI workloads effectively:

Key components of AI infrastructure for enterprises

See an explanation of each AI infrastructure layer and the market leader. In cases where there is public data on revenues or the number of employees, these were used to identify the market leader:

1. Compute

The compute layer of AI infrastructure supports the high parallel computational demands of neural networks. It allows training and inference of AI models at scale.

• AI chip makers design specialized processors tailored for AI workloads. These chips focus on maximizing throughput and energy efficiency for tasks such as neural network training and inference.
  • NVIDIA develops GPUs for matrix and vector computations, which are essential for training deep learning models and accelerating AI workloads.
• Cloud services provide cloud access to all cloud compute and storage products, including specialized hardware for AI model training and inference. They enable companies to scale their compute needs and deploy AI models to production without buying and maintaining physical hardware on premises.
  • Amazon Web Services: In addition to NVIDIA GPUs, AWS provides Trainium and Inferentia processors for training and inference on its cloud infrastructure.
• GPU cloud platforms are cloud platforms specialized in GPU provision for AI workloads.
  • Coreweave, a leading GPU cloud service, recently went public on NASDAQ.

2. Data

AI infrastructure requires well-managed data pipelines to supply models with clean, relevant inputs. The data layer supports acquisition, transformation, analytics, and storage for machine learning workflows.

• Data management and analytics platforms: Enterprise data needs to be organized, enriched with metadata, governed, and analyzed. Then, it can become a valuable source for training machine learning models.
  • Snowflake, with its enterprise-focused offering, allows businesses to organize their data and identify data sources for AI.
• Reinforcement learning from human feedback (RLHF) and other data annotation services: Annotating data helps AI models learn from existing datasets.
  • Scale AI supplies annotated datasets and evaluation feedback for aligning models with human preferences. This data is essential in training LLMs.
• Web data infrastructure: Web is the largest dataset for AI. Almost all generative AI models are trained or finetuned with data from the public web or require real-time, uninterrupted access to the web during inference.
  • Bright Data is a web data infrastructure platform. It offers datasets, web scraping APIs, proxies, remote browsers, and automation capabilities for agents to search, crawl, and navigate the web.

3. Model

The model layer includes architectures, training mechanisms, and deployment processes for AI models. It ensures experimentation, optimization, and monitoring across diverse applications such as LLMs and AI video systems.

• LLMs (Large Language Models): OpenAI started the generative AI wave and provides foundation models through its APIs and UI.
• LMMs (Large Multimodal Models): Multimodal models require high-dimensional input handling and temporal awareness. Google DeepMind’s Veo leads the development of video AI models for action recognition and video summarization tasks.
• MLOps platforms support model tracking, testing, and production rollout: Hugging Face (HF) offers tools and repositories to support model versioning, testing, and deployment across environments.

The model layer includes many platforms from programming languages like Python to packages like Pytorch and data science platforms like DataRobot. We have featured a selected number of industries, not the entire landscape.

Limitations

This is the industry view from the perspective of an enterprise buyer. Behind each industry lie other industries that sell to these industries. For example, in the compute segment, NVIDIA outsources the manufacturing of its chips to TSMC, which outsources the manufacturing of a significant share of its chip-making equipment to ASML.

AI applications you can build with the right AI infrastructure

Effective AI infrastructure enables organizations to develop and deploy various AI applications. With the right combination of hardware and software components, data scientists can support complex AI workloads, ensure data protection, and efficiently handle large volumes of data.

General applications
