Frontier AI research lab building foundation models and enterprise systems for autonomous software development and AGI applications.
Poolside is an enterprise AI coding platform and frontier research lab that builds custom foundation models, autonomous agents, and multi-agent orchestration systems deployed inside client security boundaries, with pricing available only through custom enterprise contracts. It targets large enterprises, defense organizations, and regulated industries that require on-premises or air-gapped AI development capabilities rather than cloud-based coding assistants.
Founded in 2023 by former GitHub CTO Jason Warner and Eiso Kant, Poolside has raised approximately $626M in total funding including a $500M Series B in October 2024 at a $3B valuation, making it one of the best-capitalized AI coding startups. Based on our analysis of 870+ AI tools, Poolside sits in a distinct category from developer-facing assistants like Copilot or Cursor — it builds full-stack enterprise AI infrastructure rather than IDE plugins. The platform consists of four integrated layers: Poolside Foundation Models (trained specifically for software engineering and deployed in the client environment), Agents and Multi-Agent Orchestration (single and multi-agent systems that plan, use tools, and execute in sandboxed environments governed by policies and end-to-end traces), Developer Surfaces (IDE extensions, binaries, and terminal workflows that move with engineers), and Data and Knowledge connectors (integrations with repositories, databases, data warehouses, and private corpora within strict boundaries).
The differentiator is Poolside's Forward Deployed Research Engineer model — dedicated Poolside researchers embed with client teams to design, build, and operate intelligence inside the client environment, taking joint responsibility for outcomes rather than just delivering software.

Poolside represents the most ambitious approach to enterprise AI-powered software development, combining frontier AI research with serious enterprise deployment capabilities. While extremely expensive and early-stage, their vision of autonomous software development and commitment to enterprise security makes them compelling for large organizations with the resources to pursue cutting-edge AI automation.
Custom foundation models trained specifically for software engineering rather than general-purpose LLMs retrofitted for code. Models are deployed inside the client's environment and measured against evaluations co-designed with the client team, ensuring alignment with proprietary codebases and internal quality standards.
Use Case:
Deploy sophisticated coding AI on-premises for sensitive codebases — enabling regulated industries and defense organizations to use frontier models without data leaving organizational control
Single and multi-agent systems that can plan, use tools, and execute in sandboxed environments, all governed by explicit policies and end-to-end traces. Agents can collaborate on long-horizon tasks, with full auditability of tool calls, decisions, and outputs for compliance review.
Use Case:
Automate complex software engineering workflows like refactoring large legacy codebases, generating and running test suites, and coordinating multi-step feature delivery across repositories
Dedicated Poolside researchers embed with client teams to design, build, and operate intelligence inside the client environment. Unlike professional services, FDREs take joint outcome ownership — responsible for adoption, measurable business impact, and long-term operation, not just model delivery.
Use Case:
Get frontier-lab research talent working directly inside your engineering organization to build bespoke evaluations, agents, and workflows rather than adapting a generic product
On-premises, private VPC, and workstation (defense-only) deployment with role-based access control for both humans and agents. The platform runs inside multi-cloud, legacy, and air-gapped networks without rip-and-replace, and is co-designed to meet CISO and enterprise review board requirements.
Use Case:
Stand up enterprise AI coding infrastructure in regulated, classified, or air-gapped environments where SaaS coding tools are not permitted by security policy
IDE extensions, terminal binaries, and workflow integrations that travel with engineers, combined with connectors to repositories, databases, data warehouses, and private corpora within strict security boundaries. Designed to plug into existing toolchains rather than replace them.
Use Case:
Bring AI assistance into heterogeneous enterprise stacks — from monorepos to mainframes — while keeping proprietary data governed and traceable across the development lifecycle

Poolside continues to position its platform around enterprise and government deployments, highlighting multi-agent orchestration with end-to-end traces, on-premises Foundation Model deployment, and a dedicated Government offering alongside its enterprise product. The company is actively recruiting research and engineering roles following its $500M Series B at a $3B valuation (October 2024) led by Bain Capital Ventures, with continued expansion of its Forward Deployed Research Engineer model into regulated industries.
