Trello locks free teams in read-only hell after 10 users while ChatGPT charges $20 for extra brainpower—SaaS's desperate pricing divorce

The $300 billion SaaS market is experiencing a significant shift, with traditional productivity applications and AI-native applications adopting distinct pricing strategies. By 2025, traditional tools like Notion, Trello, and Evernote are tightening their free offerings and collaboration limits, while AI applications are pricing their services based on outcomes, such as Intercom's Fin AI charging $0.99 per resolved customer support case. This fundamental difference in pricing logic is driven by the variable cost of delivering AI, which scales directly with usage, unlike traditional SaaS models where the marginal cost of adding another seat is nearly zero. As a result, AI applications are building new value structures around cognitive capabilities, with companies like OpenAI and Perplexity offering tiered structures based on access to different levels of intelligence. By 2025, nearly 85% of SaaS companies have implemented usage-based billing, with hybrid models combining fixed subscriptions and usage credits gaining ground. This bifurcation in the SaaS market has significant implications for product leaders, investors, and enterprise buyers, with AI application teams focusing on reducing churn and signaling commitment through pricing, and enterprise buyers seeking integrated workflows and consolidated platforms.
