AI Lowered Build Costs. Enterprise Governance Hasn't Caught Up.
AI-assisted development and low-code platforms have dramatically reduced the cost of building custom software, shifting the economic calculus away from buying SaaS tools for many enterprises. A Retool survey of 817 builders found that 35% of teams have already replaced at least one SaaS tool with a custom build, and 78% plan to build more custom tooling in 2026. However, enterprise procurement and governance processes remain designed for the old model where building took months and required large engineering teams, creating a mismatch that is driving widespread shadow IT adoption, with 60% of builders creating tools outside IT oversight.
TL;DR
- →AI-assisted development has reduced custom software build time from weeks or months to days, fundamentally changing the buy versus build equation for enterprises.
- →35% of surveyed teams have already replaced at least one SaaS tool with custom builds, with workflow automations (35%) and internal admin tools (33%) being the most common targets.
- →SaaS pricing models have not adjusted to this shift, still charging per-seat for generic tools while custom alternatives become faster and cheaper to build.
- →60% of builders are creating tools outside IT oversight, signaling that traditional procurement cycles cannot keep pace with the speed of modern development.
Why it matters
This represents a structural shift in how enterprises acquire and deploy software. The convergence of AI-assisted coding, mature low-code platforms, and the economics of custom development is reshaping vendor relationships and IT procurement at scale. The gap between what builders can now do and what governance processes allow is creating significant shadow IT adoption, which poses both opportunity and risk for enterprise organizations.
Business relevance
For operators and founders, this signals a major market disruption in SaaS. Companies selling workflow automation, admin tools, and BI software face direct competition from internal builds that are now faster and cheaper to develop. Simultaneously, platforms enabling rapid custom development (like Retool) are becoming critical infrastructure, and enterprises must rethink procurement to capture the efficiency gains rather than suppress them through outdated approval processes.
Key implications
- →SaaS vendors in horizontal categories like workflow automation and admin tools face margin pressure and customer churn as the cost of custom alternatives drops below the cost of buying and customizing off-the-shelf solutions.
- →Enterprise IT departments must evolve from gatekeepers to enablers, designing governance frameworks that allow rapid development while managing risk, or face continued shadow IT expansion.
- →Low-code and AI-assisted development platforms are becoming strategic infrastructure for enterprises, not niche tools, as the default question shifts from 'What should we buy?' to 'Can we build this?'
What to watch
Monitor how enterprise IT organizations respond to shadow IT at this scale. Watch whether SaaS vendors adjust pricing models or double down on differentiation through deeper integrations and domain-specific features. Track whether governance frameworks emerge that balance speed with compliance, and observe which low-code platforms gain the most traction as enterprises standardize on internal development stacks.
