As AI models have become the primary research tool for CTOs and founders, the 'AI visibility' of a processor now correlates strongly with its developer documentation quality and API stability. While market incumbents maintain high visibility, we are seeing a fragmentation where AI agents recommend different providers based on specific regional compliance and tax automation needs.\n\nOur analysis across major LLMs indicates that while Stripe remains the benchmark for developer experience, there is a growing consensus around 'Merchant of Record' (MoR) models for international SaaS and specialized infrastructure for high-growth fintech.
