PostHog comes to Seoul: Dev Korea #3 Recap
On October 16, we hosted Dev Korea #3, bringing together 75+ developers, founders, designers, and indie builders for a night focused on practical analytics, real-world product insights, and the growing international tech community in Seoul.
🚀 Developer-first analytics, explained simply
We opened the evening with a surprise greeting video from James Hawkins, co-CEO of PostHog, who welcomed the Dev Korea community and encouraged developers to build fast, stay curious, and make data-informed decisions. It was a fun start and set the tone for the rest of the night.

Then Melvin Oostendorp took the stage to break down developer-first analytics in a way that felt simple and actionable.
He showed how developers can:
- track meaningful events
- use session replay to understand real user behavior
- experiment safely with feature flags
- avoid “vanity metrics” and focus on what really matters
- make decisions based on user insights instead of assumptions

His talk made analytics feel less like a chore and more like a superpower for product teams.
📊 Real app examples from a Korean product team
Next, Max Wiersma shared how he uses analytics inside TOPIK Easy6, a React Native product built here in Korea.
He walked through:
- how they built a type-safe analytics system
- how they track dozens of custom events
- how these insights shaped product decisions
- real examples of finding problems early and prioritizing what users actually care about

It was a practical, honest look at how analytics works in real life. Not theory, but actual product stories.
The Q&A naturally led to discussions about feature prioritization, user journeys, and how teams can stay aligned when making decisions.
🎁 Swag, stickers & the PostHog raffle
After the talks, we shared a few Dev Korea community updates, and then it was time for swag.
Everyone picked up PostHog stickers, and we held a raffle for PostHog T-shirts and caps.
The winners celebrated like champions, of course.

The speakers stayed around to chat, answer questions, and meet people across the community — one of the best parts of every Dev Korea evening.
🍕 Pizza, drinks & the Dev Korea vibe
As always, we wrapped up the night with pizza, drinks, and free-flowing conversations.

People talked about the apps they’re building, product challenges, startup ideas, and life in Korea’s tech scene.
Newcomers made their first friends.
Old friends reconnected.
It was warm, open, and full of energy, exactly the Dev Korea vibe we aim for every time.
