"Powered by Fivetran" is a framework that enables developers to build data pipelines into their applications within the Fivetran platform, allowing them to access hundreds of customer accounts across various data sources without any engineering overhead. This tool helps businesses make sense of large amounts of data coming in from different applications and can be used by marketing agencies, BI or data providers, and companies building data-rich intelligence platforms. By using PBF, businesses can focus on their core offerings rather than building and maintaining integration pipelines.
