About

Built from ad monetization experience

We spent years building ad yield and bidding systems, then saw publishers struggle with mediation built for large teams. In 2024, we started Adrop to make real-time bidding available to publishers of any size.

Our Story

Why we built Adrop

Mediation tools were built around large publishers with dedicated ad operations and engineering teams. Independent studios faced the same basic choices without the same resources to configure waterfalls, manage demand partners, or improve their auction results.

Real-time bidding expanded demand-side competition, but publisher tooling remained difficult to manage. Smaller teams still had to work across separate SDK adapters, revenue reports, and technical configuration before they could operate a multi-network auction setup.

We built Adrop to make RTB mediation as simple as one SDK connection. Connect once, and we manage the adapter layer while your impressions compete across 15+ demand networks. The winning bid is selected in under 50ms, with no revenue share.

We are based in Seoul and bootstrapped. Our flat-fee model means we do not take a share of publisher revenue, so stronger auction results benefit you directly.

Our Values

How we work

Publisher-aligned incentives

We charge a flat fee and take no revenue share. When your eCPM rises, you benefit directly. That structure guides the product choices we make.

Clear data

You can see bids, fills, and impressions clearly. We do not obscure network comparisons or hide weak demand performance. The data stays available for your decisions.

Simple auction setup

A publisher with one engineer should access the same auction efficiency as a team with dedicated ad operations. We keep the complexity in our infrastructure, not in your setup.
