Roi Nam and the trouble with a good number

In 2025, Roi Nam marked ten years of AB180 by welcoming another person into the CEO job. The person was Hunjae Jung, his co-founder, who had spent those years helping build the company’s technology. Nam described a colleague from whom he had learned, a mentor and “a trusted friend”. In an industry fond of presenting founders as solitary protagonists, it was an appealingly crowded account of leadership.

The arrangement had a practical shape. Nam would concentrate on sales and external activities; Jung would focus on products and internal operations. A company that sold ways to understand growth was adjusting how its own work got done. There was no need to manufacture a dramatic rupture. Two people who had built something together were dividing the next set of responsibilities.

That decision offers a useful entrance into Roi Sungpil Nam’s career. He works where engineering meets the rather less orderly business of persuading people to buy things. His public record includes developer instructions, arguments about company culture, conversations with game publishers and forecasts about artificial intelligence. Running through them is a recurring question: what does a promising result actually tell you?

A business student gets inside the machinery

Nam studied business administration at Seoul National University’s College of Liberal Studies. His early career also involved the technical work of interpreting language: as a co-founder and chief strategy officer at Bitgenstein, he worked on opinion mining and business intelligence using natural language processing. Customers’ words could become information that a business might use. The commercial question and the engineering problem were already sharing a desk.

In 2015, he was selected among Software Maestro’s Top 8 and received a ministerial prize in South Korea. That was also the year AB180 began. The combination makes his route into marketing technology less tidy than a standard founder biography: a business major, recognized for software engineering, building a company concerned with how businesses understand their customers.

A piece of writing from April 2016 supplies a more revealing detail than a list of titles. Nam published a guide to Android install tracking using the Google Play referrer. It moved through implementation, receiving the relevant data and testing the result with Android Debug Bridge. Here was a founder explaining how to check whether the plumbing worked.

The guide also described limitations. Certain installation routes fell outside the method; the timing of a response mattered. It is a small, technical artifact, but the habit it records matters to the larger story. A number becomes useful when someone understands how it arrived. Otherwise, even an attractive dashboard can amount to an expensive way of looking pleased.

The sale behind the spreadsheet

Airbridge, the measurement business associated with AB180, addresses a deceptively ordinary problem. A company spends money to attract customers and wants to know which activity helped. The customer may encounter several messages, move between a website and an app, and make a purchase later. Marketing would be a more restful occupation if everyone arrived carrying a neatly completed explanation.

Nam’s work has involved both the tools and the businesses trying to use them. By 2020, his Forbes profile described AB180’s customer analytics work and named Burger King, SK Telecom and Netmarble among companies that had used its services. That year he appeared on the publication’s Asia 30 Under 30 list in Media, Marketing & Advertising. The recognition placed an engineer in a category about reaching people.

He has applied similar measurement habits inside his own sales process. AB180 used Salespanel to score leads and synchronize information with Pipedrive. In a customer account of that work, Nam described using the scores to prioritize whom the team should contact first. The question was wonderfully concrete: with a finite day, who gets a conversation?

There is a useful restraint in that example. The data helps allocate attention. A salesperson must still have the conversation. Nam’s career has continued across that boundary, from explaining systems to meeting the people expected to trust them.

His objection to the easy growth story

In a 2019 essay on growth, Nam argued that a collection of techniques was an inadequate account of how companies improve. He put culture at the center: shared goals, rapid product improvement, cooperation among disciplines, visibility into data and effective use of marketing technology. A new tool could help, but the organization had work to do.

He distinguished meaningful customer behavior from outward activity such as installation counts or website sessions. Teams needed to identify the actions connected to the business’s progress, then organize their efforts around them. His account of product work included a repeating sequence: experiment, analyze, share the learning and ship an improvement.

The appeal of that sequence lies in its demand for follow-through. A result on a screen creates another obligation. Someone has to understand it, tell colleagues what happened and change the product. The person purchasing advertisements and the person writing code need enough common language to make that possible.

Read beside his earlier tutorial, the essay shows his field of view widening. First, make sure information can be collected. Then consider whether the people receiving it can act together. Across those two pieces, his work brings the mechanism back to the decisions around it.

A bridge with people on it

By October 2024, Nam was describing a different kind of connection. He had joined Airbridge colleagues and partners from ONE Store, Moloco, ADPOPCORN and ACTIONFIT in Wuhan. They met the Wuhan Gaming Association and more than 20 Chinese gaming studios and publishers. His account of the visit moved readily from marketing measurement to introductions across borders.

Publishers wanted connections with developers, app stores, advertising platforms and local partners. Nam saw Airbridge occupying a place among those conversations. The company name was doing double duty. Some bridges carry information; others depend on getting the right people into the same room.

At a Seoul gaming gathering with Moloco, Sensor Tower and two & a half gamers, he described another boundary becoming less distinct. Marketers were extending into research, game design, business intelligence and personalization. He called them “marketing producers”. The label suggested people involved in shaping what gets made, with responsibilities that continue after buying an audience.

His interview work has a related range. He has sat down with App Masters founder Steve Young on subscription app growth and Tangent founder Vahe Baghdasaryan on monetization. These exchanges put Nam in the questioner’s chair. They also keep his public work close to practitioners who have to make a price, a trial or an acquisition campaign function outside a presentation.

Five concepts, one decision

In his 2025 conversation with Andy Carvell, Nam discussed acquisition testing becoming part of product development. Teams could test alternatives early and use the response to decide where to invest more effort. His formulation was brisk:

“You can build five different concepts and pick the winner.”

Roi Nam / on testing product concepts

That view gives marketing an earlier appointment in the development calendar. Instead of waiting for a finished product, a team can learn whether a concept attracts interest while changing direction remains relatively manageable. Nam also discussed the complications of iOS measurement and the need to combine approaches. Faster experimentation still needs an intelligible result.

There is a tension here worth keeping. Speed creates more chances to learn, and more results to interpret. Generating alternatives does not by itself settle which one deserves a company’s time. For someone who began by explaining how to trace an install, the multiplication of possible products makes the interpretation problem larger.

His recommended reading adds a pleasing human footnote. On the same podcast, he chose The Challenger Sale, by Matthew Dixon and Brent Adamson. An engineer’s public reading recommendation turned out to be a sales book. It fits a working life spent crossing between technical explanation and commercial judgment.

The next experiment takes a larger budget

In February 2026, Nam forecast more consumer apps as AI coding and no-code tools made development easier. He expected games and consumer apps to converge around similar methods of testing, acquisition and monetization. He also predicted a larger role for reinforcement learning in marketing decisions. These were expectations about the future, with results still to come.

By July, AB180 had announced a KRW 21.4 billion Series C led by Atinum Investment. The company described developing and testing Airbridge GO, an AI agent solution intended to extend through marketing analysis, planning, creative production and campaign operation. Nam linked the next phase to continued AI development and international expansion. The ambition was reaching further into the actions that follow measurement.

It is a substantial change of scale from a developer tutorial. Yet the earlier questions remain recognizable. How was the result produced? What does it justify doing next? Who is responsible for making that decision useful? His partnership with Jung gives the last question an immediate, human answer: the responsibility is shared.

Nam’s next chapter will be judged by what those systems and that partnership produce. For now, the most revealing image may be the simple one from the anniversary announcement: a founder making room beside himself, after ten years of work together. Even a career spent studying numbers contains things that take a while to count.
