No free plan. The cheapest way in is Enterprise at Custom. Consider free alternatives in the ai coding assistants category if budget is tight.
Poolside operates at a fundamentally different layer than developer-facing assistants. Where Copilot and Cursor are SaaS IDE plugins running on shared cloud models, Poolside ships custom foundation models deployed inside the client's own infrastructure along with multi-agent orchestration, governance, and embedded research engineers. Devin is closer conceptually as an autonomous agent, but Devin is a hosted product with public pricing while Poolside is an enterprise platform with bespoke deployments and Forward Deployed Research Engineers who take joint responsibility for business outcomes. Based on our analysis of 870+ AI tools, Poolside is one of very few vendors combining foundation-model training, agent orchestration, and deployment services as a single enterprise offering.
Poolside does not publish pricing and operates exclusively on custom enterprise contracts. Given the $500M Series B funding, the Forward Deployed Research Engineer staffing model, and the on-premises foundation-model deployment footprint, engagements are typically six- to seven-figure multi-year commitments. There is no free tier, no trial, and no self-serve signup. Organizations interested in the platform engage through direct sales via the 'Talk to us today' contact on poolside.ai. Compared to per-seat tools like Copilot at $19–39/user/month, Poolside is structurally oriented toward large enterprises rather than individual developers.
Poolside supports three deployment modes: on-premises (in the client's own data center), private VPC (inside the client's cloud account on AWS, Azure, or GCP), and workstation-based installation, though the workstation option is restricted to defense clients. All modes keep data inside the client security boundary — Poolside explicitly states 'your data never leaves your control.' The platform is designed for heterogeneous environments including multi-cloud, legacy systems, and air-gapped networks, and includes role-based access control for both humans and agents, end-to-end traces, and governance aligned to CISO and enterprise review board requirements.
Forward Deployed Research Engineers (FDREs) are Poolside researchers who embed directly with client engineering teams to design, build, and operate AI systems tailored to the client's environment, codebases, and workflows. Unlike traditional vendor support or professional services, FDREs take joint responsibility for outcomes, adoption, and measurable business impact rather than just handing off a model. This hands-on delivery model is a core reason Poolside commands enterprise pricing — clients get dedicated research talent rather than a shrink-wrapped product. It also explains why engagements span months rather than hours and why the company targets high-consequence software environments.
Poolside was founded in 2023 by Jason Warner, former CTO of GitHub, and Eiso Kant, former founder of source{d}. The company's stated mission is 'for artificial general intelligence to drive abundance for humanity,' with software engineering chosen as the strategic beachhead on the path to AGI. The reasoning: software development requires understanding the world, multi-step complex reasoning, and long-horizon planning — capabilities that mirror human cognition and are well-suited to reinforcement learning. Poolside is headquartered in Paris with offices in the US and has raised roughly $626M in total, including a $500M Series B led by Bain Capital Ventures in October 2024 at a $3B valuation.
