About
Poolside AI was founded in 2023 in San Francisco with a singular mission: to build the world's most capable AI systems purpose-built for software engineering. The company was co-founded with deep roots in AI research and an early conviction that general-purpose LLMs would fall short for enterprise-grade coding tasks. Poolside's core technology centers on code-native foundation models trained specifically on software development workflows, enabling reasoning and generation capabilities far beyond what general models can deliver for engineering teams.\n\nPoolside's flagship offering is a suite of specialized coding LLMs designed for enterprise deployment, branded under the Project Horizon initiative which includes plans for a 2GW data center to support large-scale inference and training. The platform integrates into existing developer toolchains, supporting code generation, review, debugging, and transformation tasks across complex enterprise codebases. Customers gain access to models fine-tuned for accuracy, latency, and security requirements that consumer-facing tools cannot match, positioning Poolside as a serious alternative to general-purpose AI coding assistants for regulated industries and large engineering organizations.\n\nPoolside has achieved approximately $50M in revenue as of 2025 and has raised over $2 billion in funding, including a landmark ~$1 billion investment from Nvidia, reflecting deep strategic alignment with the AI infrastructure ecosystem. The company carries a $12 billion valuation, making it one of the most richly valued AI startups in the coding vertical. With Nvidia's backing and a focus on vertical specialization, Poolside is positioned to become the dominant AI platform for enterprise software development at scale.
Most cited AI agent framework in 2026; LangGraph has 8,200+ GitHub stars. $25M Series A at $200M valuation. LangSmith observability platform for production agents. Used in majority of enterprise multi-agent deployments; 80K+ GitHub stars total.
About
LangChain was founded in 2022 by Harrison Chase and emerged from the open-source community as the dominant framework for building applications powered by large language models. Originally a Python library, it provided developers with composable building blocks—chains, agents, memory modules, and tool integrations—to connect LLMs with external data sources and APIs. The framework addressed a critical gap: making it practical to build production-grade LLM applications beyond simple prompt-and-response patterns.\n\nLangChain's product portfolio has expanded significantly, with LangGraph serving as its graph-based orchestration layer for stateful, multi-actor AI agent workflows. LangSmith provides observability, debugging, and evaluation tooling for LLM pipelines in production. The commercial LangChain Platform offers hosted deployment and collaboration features for enterprise teams. These products target AI engineers, ML teams at enterprises, and the broader developer community building agent-based systems and RAG pipelines.\n\nWith over 100,000 active developers and LangGraph accumulating 8,200+ GitHub stars, LangChain remains the most cited AI agent framework heading into 2026. The company raised a $25M Series A at a $200M valuation and has become deeply embedded in how enterprises build and deploy AI agents. Its ecosystem of integrations—covering hundreds of LLM providers, vector databases, and tools—makes it a foundational layer of the modern AI application stack.
