Leadgence is a company that uses MongoDB to grow revenue for enterprise companies targeting small and mid-size businesses, offering smart actionable data to support sales and marketing efforts in the financial services sector. The company has evolved its products since launching, including the launch of DataSeeker, an application delivering event and change-based triggered actionable data intelligence. Leadgence chose to build with MongoDB due to its document-native approach and ease of use through MongoDB Atlas, which made it easy to spin up infrastructure as code with Terraform. As the company has scaled, it has used MongoDB as an analytics database, running online inquiries on it for instant results. The MongoDB for Startups program has been helpful in supporting Leadgence's growth, providing consulting sessions and guidance. Sergey, co-founder of Leadence, is constantly learning new lessons as a company, including the importance of solving problems in simple ways and staying up-to-date with market trends through networking with professionals in entrepreneurship and technical spaces.
