Our take
Consumer financial data is notoriously inaccurate and many data brokers depend on census data, surveys, and zip codes, which are infrequently updated and can lead to false generalizations. This dependency on inaccurate information leads to costly financial mistakes for businesses.
With a focus on the affluent, Windfall delivers a precise net worth figure for individual households which is updated on a weekly basis. The platform collates accurate, up-to-date information from public and private domain records through partnerships with data vendors. It syncs with commonly used tools such as Salesforce, HubSpot and Shopify to power data-driven outreach to customers. And it's customer base includes hundreds of nonprofits as well as businesses across a wide range of industries looking to better target their own sales and marketing efforts.
Having raised significant funding, Windfall has gone on to enjoy impressive year-on-year growth. With this success, it intends to double down by expanding its sales and marketing reach and further developing its product, including its application to give go-to-market teams direct access to its platform.
