Clarisights is a marketing analytics platform built on a custom data infrastructure stack (ClickHouse, Spark, Elixir) that prioritizes performance-marketing use cases over generic BI. The technical roadmap reveals infrastructure-first priorities: a JIT compiler for formula evaluation, two HTAP database engines, and a custom pipeline orchestration layer—investments that suggest they're moving away from reliance on external query engines and toward proprietary data processing. Minimal hiring velocity (5 roles, all mid-level) paired with heavy infrastructure work indicates a consolidation phase focused on architectural debt and scaling stability rather than feature expansion.
