About Foaster
Summary
Foaster deploys AI agents to conduct organization-wide employee interviews, map operational workflows, surface bottlenecks, and produce an AI transformation roadmap, delivering in two weeks what traditional consulting firms take much longer to complete. Human experts review the outputs and feed corrections back into the system, replacing the consultant-heavy model with an agent-first one. The company targets enterprises seeking to understand where AI should change how they operate.
Business model
A one-time assessment fee, a recurring monthly support plan, and an enterprise deployment tier with dedicated engineers.
Go-to-market
Enterprise buyers engage through a booked demo or call, choosing between a standalone diagnostic, ongoing monthly adoption support, or a full embedded deployment.

The AI-native McKinsey
Foaster is building the AI-native McKinsey, starting with AI transformation. We deploy AI agents that interview a company's employees at scale, map how work actually gets done, identify bottlenecks and AI opportunities, and draft a transformation roadmap in just 2 weeks. Expert consultants review the final outputs, add judgment where it matters, and feed their corrections back into the system. We believe current AI models already have the capabilities required to automate most of the work consultants do. But traditional consulting firms use them to improve the old model: helping consultants work faster. Foaster is instead rebuilding a new model from scratch, where agents do the work that needs scale and humans review the final outputs, bring expertise, and improve the system overtime. We are starting with AI transformation, then progressively expanding to more and more consulting projects using the same approach. Every mission creates structured knowledge from interviews, workflow maps, recommendations, and expert corrections, so the system gets better with every client engagement. The $500B consulting market will eventually be run by our AI agents and a small number of expert humans.
