Toxic Software: Investment Funds Refuse to Buy SaaS Companies Due to AI Obsolescence Risk

The Mergers and Acquisitions (M&A) market has begun to factor technological obsolescence into financial valuations. On August 19, 2026, a telling precedent was revealed: the Apax fund backed out of buying British software developer Pinewood Technologies (ultimately sold to Ridgeview Partners for £545m).

The reason for the refusal is a direct fear of artificial intelligence. Investors have realized that traditional SaaS products, based on manual entry and hard code, are rapidly losing relevance under the onslaught of autonomous AI agents. The business model of classic software vendors is deemed vulnerable. If a product lacks a clear migration strategy to Agentic AI, it becomes a toxic asset that does not guarantee a return on investment within a 3–5 year horizon. This is a stark macroeconomic signal for the entire B2B industry: venture capital will no longer bail out legacy code, demanding that developers fundamentally integrate neural networks into their architecture.
