The software-as-a-service (SaaS) industry is undergoing a rapid transformation driven by advances in AI-powered development tools, often referred to as "vibe coding." This approach, which leverages large language models such as Claude, Gemini, and ChatGPT, enables developers to build software startups with minimal code, accelerating the pace of innovation. A Swedish AI unicorn has emerged as the fastest-growing software startup by adopting this method. Industry experts predict that within the next 36 months, between one-third and one-half of existing SaaS companies may either cease to exist or be reduced to agentic platform data feeds. This shift is prompting a reevaluation of traditional enterprise SaaS models, as major players like Microsoft, Google, and ServiceNow explore AI-driven agents that could transform SaaS offerings into more commoditized databases while capturing higher margins through AI. The era of "fast fashion" SaaS, characterized by rapid prototyping and frequent new app launches, is expected to lead to a proliferation of software products, including many low-quality clones initially. This environment poses challenges to established SaaS companies, with questions arising about which firms, including giants like Palantir Technologies ($PLTR) and Salesforce ($CRM), will maintain their competitive moats amid the rise of agentic platform companies that integrate and absorb lagging SaaS providers.
