Windfall is a people-data intelligence platform serving go-to-market teams with ML-powered insights. The tech stack reflects a product-sales hybrid: deep integrations with Salesforce, Outreach, LinkedIn, and ZoomInfo on the GTM side, paired with a data science foundation (Python, scikit-learn, XGBoost, PostgreSQL). Hiring skews heavily toward product (4 open roles) and sales (4), with most positions at senior+ level—typical of a Series A/B growth stage company scaling customer success and product-market fit. Active projects center on custom segmentation, propensity modeling, and partner onboarding; pain points cluster around data aggregation, standardization, and scaling GTM operations.
