Retool Build vs Buy 2026: 35% of Enterprises Already Replaced SaaS, 78% Plan More — Top Targets Are Workflow, Admin, BI, CRM
Retool's 2026 report surveying 817 enterprises reveals 35% have already replaced at least one SaaS tool with custom-built software, and 78% plan to build more in 2026. Top replacement categories: workflow automations (35%), admin tools (33%), BI (29%), CRM (25%), project management (23%), customer support (21%). Shadow IT is accelerating this: 60% of builders built something outside IT oversight in the past year, and 72% use AI to write code they integrate into larger projects. This is the most concrete survey data on the SaaS replacement wave — enterprise teams are already doing it, not just talking about it.
