Financial Services Santa Monica, CA 51–200 employees Founded 2019 Privately Held

Rain operates a financial wellness platform for mid-market employers, distributing earned wages on-demand to employees. The tech stack reveals a security-first and data-intensive operation: heavy investment in application security scanning (Semgrep, Snyk, Trivy, Burp Suite), container hardening (eBPF, runtime security), and data pipelines (Kafka, Flink, dbt, Snowflake, Fivetran). Active projects in threat modeling, CI/CD integration, and cash-flow tooling signal ongoing product expansion; sales hiring (6 open roles) outpaces engineering (4), suggesting sales-led growth into new verticals.
