Case Study: Optile achieves clearer API documentation and faster, professional diagrams with Lucidchart

Optile uses Lucidchart to document and develop their systems while also providing them with clean, professional diagrams to tell their story to their customers

optile is a medium-sized B2B fintech that provides an open payment orchestration API to help merchants connect to any payment method or provider. The team struggled with abstract, text-only technical documentation: hand-drawn sketches proved the concept but lacked polish, free tools weren’t professional enough, and creating diagrams in Photoshop required a designer and slow back-and-forth.

Switching to Lucidchart gave optile an intuitive, cloud-based way to create, edit, share, and integrate professional diagrams (including AWS/GCP libraries and Confluence integration) without relying on designers. The product team now produces clear API flows, networking and compliance diagrams (e.g., for PCI DSS), communicates more effectively with customers, speeds collaboration, and makes complex system behavior immediately understandable.
