We sit down with James Campbell, CTO & Co-Founder @ Great Expectations, to discuss his founding journey, considerations for starting open source, making community-driven decisions, and navigating the tension between your product vision & product roadmap. We also cover the phases that Great Expectations has cycled through, balancing the role of personal biases when making product / business decisions, how making an open-source product impacts marketing decisions, and James’ best recommendations for building out the product function as a product-involved founder.
