Goodmarketing Co., Ltd.
Goodmarketing Co., Ltd. develops and runs its own AI-powered mobile apps and services, and grows them with advertising and data.
What we do
We build AI features that live inside our products — drafting replies to support inquiries, checking mission photos and reading receipts — with models running on our own hardware and a person confirming the results.
One team takes iOS and Android apps from planning and design through development, store release and ongoing updates, together with the servers and admin web behind them.
We run rewarded ads inside apps, collect Google Ads results automatically and manage store listings — the work of getting apps found and earning. We also offer ad brokerage and marketing consulting.
We build our own dashboards for sign-up funnels, hourly acquisition and ad revenue, and make decisions from them. Missing data stays blank rather than being estimated.
What runs in our products today.
Apple Vision reads the text on receipt photos and a vision-language model organizes items and amounts. Only items a person confirms reach the ledger.
We generate word pronunciation audio for our learning apps and serve it through cloud storage and a CDN.
The models behind reply drafts and photo checks run on our own office hardware, so user data is not sent to outside AI services.
A shared server for many apps — five social logins, a points ledger, server-verified rewarded ads, automatic gift cards and push.
Fixes to app screens and features ship through our own update server without waiting for store review.
We connect what our products need — Toss mini-apps, e-contracts, identity verification and SMS verification.
