AI-native risk decisioning platform for fraud, credit, and compliance

Technology, Information and Internet Palo Alto, CA 51–200 employees Founded 2021 Privately Held

Oscilar operates a no-code risk platform built on a polyglot stack (Java, Python, Go, Kafka, ClickHouse, Spark, Dask) designed for real-time decisioning at scale. The engineering-heavy org (22 engineers, 5 data specialists) is actively shipping a no-code configuration layer, advanced fraud models, and observability infrastructure — suggesting they're moving beyond single-use detection toward a unified decisioning fabric. Pain points cluster around latency, resilience under traffic spikes, and multi-region reliability, which the architecture (Kafka + ClickHouse + Spark) is built to address.
