What makes StartGiving unique is that they invest what you give instead of granting it immediately so you can grant year after year, with as little as a single donation. Thanks to the multi-tenant architecture, your donations have a lasting impact.
Our challenge was to build all parts of the system based on the true multi-tenant architecture from scratch, but before we did a tremendous work of defining requirements and final look-and-feel of the platform. Our team worked very closely with our customers describing every part of the future product.
Another challenge was to develop features with high quality, as SEPA payments integration and storing personal user data imposes certain responsibility to developers and QA team.
