Software Development Stockholm, Stockholm County 201–500 employees Founded 2014 Privately Held

Funnel operates a marketing intelligence platform built on modern data infrastructure (Rust, Arrow, Iceberg, DataFusion) paired with advertising APIs (Meta, Google, TikTok) and CRM/sales tools (HubSpot, Gong, Sales Navigator). The tech stack shape—heavy on columnar storage and distributed systems—combined with active projects around scalability and next-gen platform development, signals an engineering team focused on handling high-volume ad account data. Pain points around renewal forecasting accuracy and churn reduction indicate the product is moving beyond pure analytics toward revenue-impact measurement.
