You Built Right. Now Build Bigger: Why Fast-Growing Fintechs Are Moving Beyond PostgreSQL

Fast-growing B2B SaaS companies in regulated industries like financial services often encounter scalability issues with PostgreSQL when nearing or surpassing $100M ARR, as its single-writer architecture becomes a bottleneck in handling write-heavy workloads. To address this, many companies adopt specialized tools for analytics and AI features, which, although effective individually, create synchronization challenges and operational complexity when integrated. The ideal solution is a unified HTAP (Hybrid Transactional/Analytical Processing) system, such as SingleStore, which seamlessly combines transactional and analytical capabilities without synchronization layers, supporting compliance and AI-readiness as core architecture features. SingleStore, which offers PostgreSQL compatibility, provides a streamlined migration process that will soon be further simplified with AI-assisted migration capabilities, enabling companies to overcome PostgreSQL's limitations and confidently scale their infrastructure to meet enterprise expectations and growth opportunities.
