As answered by people managing PropelAuth and SourceLoop.

SourceLoop connects marketing data directly to leads, not just website traffic. It captures complete lead journeys—from first click to conversion—so teams can see which campaigns truly drive results. Unlike traditional analytics tools, SourceLoop turns attribution data into actionable insights right inside your CRM.

Most attribution tools stop at visitor tracking. SourceLoop goes further by linking each lead’s source, channel, and campaign to actual sales outcomes. It’s simple to install, works with any form or CRM, and includes built-in dashboards and lead management—so you get full visibility without complex setup or extra tools.

SourceLoop was created to solve a common problem: businesses were generating leads but had no idea which marketing efforts were driving them. Our team set out to build a simple, powerful tool that connects lead data, marketing attribution, and CRM insights—so every business can track, analyze, and grow with confidence.
SourceLoop's answer:
SourceLoop is built using React, Node.js, and PostgreSQL, with server-side tracking and REST APIs for reliable data capture and integration. The system is optimized for scalability, accuracy, and real-time analytics.
