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

What this post added

This post details how SingleStore addresses the scaling limitations of PostgreSQL for fast-growing fintechs, particularly those reaching the $100M ARR mark. It highlights the core technical constraint of PostgreSQL being a single-writer system and the fragility introduced by 'bolt-on' specialized tools for analytics, time-series, and vector indexing. The post positions SingleStore as an HTAP system that natively combines rowstore and columnstore for transactional and analytical workloads on the same data, eliminating ETL and synchronization layers. It emphasizes SingleStore's capabilities in distributed writes, horizontal scaling, native vector and full-text search, compliance, multi-tenancy, and predictable operational overhead. It also outlines a service-by-service migration strategy from PostgreSQL, leveraging tools like Pipelines and SingleStore Flow.
