Rebuilding SaaS for AI: Where the done-for-you experience finally began
freee is rebuilding its product from the ground up to become the SaaS that AI finds easiest to use — so back-office work finishes itself and only the outcome reaches the customer. Co-Founder & CAIO Ryu Yokoji walks through the design philosophy behind freee-mcp (released as official OSS), the guardrails that let AI fully run core operations like accounting and payroll, and the shift of customers becoming builders.
