About OpenNexus

An agency that works
to revenue metrics.

OpenNexus is a full-service digital advertising agency whose dedicated teams plan and run search, social, video, commerce and global advertising. We bring accounts and data scattered across platforms under one standard, and move budget in order of performance.

Who we are

In digital advertising, the platforms, the data and the agencies are all finely fragmented. The Nexus in OpenNexus means the connection point between them.

Search, social, video, commerce, app and global campaigns are run by specialist teams. KPIs, measurement standards and report formats are unified. Instead of coordinating several agencies, the advertiser talks to one strategy lead.

Behind our operations is NexaAI, the AI platform we built ourselves. NexaAI takes on repetitive work such as data collection, anomaly detection, report writing and creative variants, and the team spends its time on work that needs judgment.

Why OpenNexus

Why advertisers
choose OpenNexus.

01

One full-funnel team

Strategy, media, creative, data and engineering people sit in one organization. None of the data silos and accountability gaps that come with splitting agencies by platform.

02

Our own AI platform, NexaAI

We eliminated the hours spent manually copying platform reports. NexaAI handles real-time monitoring, automated reports and creative generation; strategy and decisions stay with the team.

03

Business KPIs as the standard

Platform metrics such as CTR and impressions are used for diagnosis. Goals and reporting are set on metrics that appear on the advertiser's income statement: revenue, profit and LTV.

04

Global operations in 5 languages

We plan and run campaigns in-house in Korean, English, Japanese, Chinese and German. Overseas expansion and Korea market entry campaigns are managed within the same team structure.

Core values

How we hold ourselves.

Report results as they are

We don't cherry-pick good numbers. We share what didn't work, and why, first.

Follow through to sales

We don't stop at our platform metrics. We check how the work affected the advertiser's sales.

Test small, test often

Hypotheses get tested in live campaigns, not meeting rooms. Every week, in small increments.

People make the call

AI handles data processing and repetitive work. Decisions on budget and strategy are made by the team.

We start by auditing
your current account.
