Prosper Marketplace Tech Stack

Peer-to-peer lending marketplace for personal loans, home equity, and credit cards

Financial Services San Francisco, CA 201–500 employees Founded 2005 Privately Held

Prosper operates a multi-product lending marketplace serving 2M+ customers across personal loans, home equity, and credit products. The tech stack—BigQuery, dbt, Looker, Python, R, and production-grade containerization (Docker, Kubernetes, Terraform)—reveals a data-driven underwriting and risk-analytics operation. Active hiring skews heavily toward data (5 roles) and finance (4 roles) relative to engineering (2), signaling Prosper is scaling credit decisioning and capital management rather than platform infrastructure.
