AI-powered revenue intelligence platform for B2B sales and marketing

Software Development San Francisco, California 1,001–5,000 employees Founded 2013 Privately Held

6sense operates a revenue AI platform spanning predictive intelligence, account data, and GTM automation, built on a polyglot stack (Java, Python, Go) running on AWS/GCP/Azure with Apache Spark, Airflow, and Snowflake for data pipelines. The org is sales-led (28 sales roles vs 14 engineering) yet heavily weighted toward senior talent, and current projects reveal infrastructure concerns—cloud strategy work, data pipeline scaling, and system reliability improvements suggest they're managing performance bottlenecks as data volume grows.
