MarTech.org reports that a new 'buy and vibe code' procurement model is emerging where organizations keep their core SaaS platform but build custom functionality for gaps rather than waiting for vendor roadmaps. Noah Brier of Alephic argues that since no one uses all of a platform's features, vibe coding enables filling specific gaps without vendor dependency — shifting the threat model from 'replace the platform' to 'erode the upgrade revenue that funds platform development.'
