Ad Monetization Platform Prebid.js + Google Ad Manager + Google Ad Exchange Web & App Monetization

We are building an ad monetization platform similar to Freestar and AdPushup. The platform helps website and app publishers maximize their ad revenue. We are a Google Partner with access to Google Ad Exchange (AdX) demand and have accounts with multiple SSP/Prebid partners. Note: We are not currently an MCM (Multiple Customer Management) partner, so AdX demand is served through our own GAM account.
The platform consists of three main parts:
• A JavaScript tag that publishers place on their website which handles everything: running Prebid auctions, calling GAM, rendering ads, and reporting data back to us
• A backend / admin dashboard where we configure everything per publisher: ad units, bidders, floors, formats, and settings
• A publisher-facing dashboard where publishers can view their revenue, impressions, and performance data
