Microsoft alternatives

Microsoft sells AI to organisations at platform scale: Copilot assistants and agents for work, the Azure AI platform for building AI applications, and the business software they run inside. Its recorded industry is enterprise AI software, spanning assistants, an AI platform and business applications in one profile. Buyers comparing AI platforms and infrastructure often weigh that breadth against narrower tools built for a single job, a single data problem or a single latency requirement. Nous, founded in London in 2021, is an AI household agent that manages bills, switches providers, cancels subscriptions and handles everyday admin for United Kingdom households, mainly over WhatsApp. OpenAI is an AI research and deployment company whose business products include ChatGPT for business and enterprise teams, an API platform for building on its frontier models, and an agent platform for building agents that act across business systems. PuppyGraph, founded in Santa Clara, California in 2023, builds a graph query engine that sits on top of the warehouses, lakehouses and databases a company already runs, letting teams query their tables as one unified graph in place. Reactor provides real-time AI infrastructure for video, robotics and world models, letting teams run leading models on its platform or deploy their own at ultra-low latency. Choose Microsoft for enterprise AI inside its business software, Nous for household admin, OpenAI for foundation models and agent tooling, PuppyGraph for graph queries over existing data, and Reactor for low-latency real-time deployment.
