1. Intro & Guest Introduction

• The very first episode of the Antler Podcast kicks off 🎉
• Today's theme: Developers, startups, and teams
• Guest: Kim Hwan, CTO of Olive Young
  • Diverse career: Shinsegae, startup founding with both failures and successes, exits, and now CTO at a large corporation
  • "I spent a long time at Shinsegae, did various kinds of development, had startups fail on me, had some succeed, did an exit, and now I'm at a large company."

2. Developers, Entrepreneurship, and Organizational Change

2-1. Early Experiences and Startup Culture

• In his early twenties, living with roommates and trading business ideas back and forth
• "Back then there was a lot of talk about trying to start something, and we tried to build all kinds of crazy web services."
• Joined 5Startups' first cohort in the US and gained fundraising experience
• After returning to Korea, joined a second-hand goods service CP, then sold a blockchain startup to Binance
• "I've done the startup thing, been a CTO, been a CEO, and now I'm a CTO at a big company…"

2-2. Differences Between Large Companies and Startups

• The fear of joining a large company
  • "When you're junior, it's honestly pretty scary. Titles and ranks — those people are above me, I'm below them…"
  • "But when I actually got there, everyone had this feeling of let's work hard together. I realized I could ask questions, that it wasn't about commands but about collaborating — that dynamic made it easy to settle in."
• The average performance bar at large companies
  • "If my capacity is 100 and I only work at 70, I still get praised, I get work-life balance, and I go home."
• The flexibility of startups
  • "There were no developers in the company originally — none at all. Until 2021 most development was outsourced. When problems came up you fixed them; building the team came first."

3. Evolving Roles and Collaboration Within Organizations

3-1. Startups Without Product Managers

• "When I was at Sungo there were no PMs. Engineers and designers all understood the product deeply."
• Shared understanding and autonomy
  • "Instead of writing specs and saying 'build exactly this,' we had shared context, so engineers just built things on their own initiative."

3-2. The Rigid Structure of Large Companies

• "As a company grows, each team's role becomes clearly defined, specs have to be written more rigorously, and because requirements can't change, I've seen a lot of cases where the business suffers."
• "If you're just doing assembly on a factory floor, you don't know what the whole thing is for. I'm just tightening this one screw — I don't know what it's going into."

3-3. Silicon Valley and Agile Culture

• "The reason people admire Silicon Valley is that back then your job was defined and you just did that. But the world changed — apps, web apps — and now you have to think about how customers can actually use the thing well."
• "Software is what changed that, and Toss is a great example of showing what that looks like…"

4. The Developer's Role, Growth, and Impact

4-1. Understanding Operations and Business

• "If you don't do operations, you can't do product planning. Developers too need to monitor every day and know how to iterate and how to scale."
• "The first thing I did was focus on hiring people who could both operate and develop."

4-2. Efficiency vs. Speed

• "There's no single right answer in software design. Often what matters most is shipping fast."
• "A startup with 100 daily visitors setting up a feast for 10,000 people — you only need to serve 100."
• "Baemin didn't start by taking orders through an app. They handed out flyers, connected phone numbers, set up a call center… because sales weren't happening."

4-3. Market Validation and Trade-offs

• "For startups and early-stage services, I think the most important thing is getting something — anything — built."
• "How do you validate the market? Start with what's already available. Experience matters, and if you can't make good trade-offs, it's hard to grow."

5. Organizational Structure and Applying Agile

5-1. Adopting Agile at Large Companies

• "Large companies have developed a lot of theoretical grounding, consulting, and posture around working agile."
• "With a small team you can sit next to each other and work agile, but as numbers grow, requests pile up, misunderstandings emerge, and you have to build systems."

5-2. Introducing Squads (Virtual Organizations)

• "We introduced what we call squads — virtual org mappings where people think through problems together. One team has a product owner, engineers, a designer, data, and business."
• "At Coupang too, teams were split by function — like the shopping cart team — each with a clear mission."

6. Qualities of a Startup CTO / Engineer

6-1. Survival and Short-term Results

• "You need to think a lot about the company's survival, and you need to take a short-term view. Nobody knows what happens in three years."
• "In the end what we have to do is figure out how to survive the next year, decide what to do in the next three months, and apply things with trade-offs along the way."
• "Short-term: I built this thing, the problem got solved, I created impact. People who can do that are the ones I consider truly excellent."

6-2. Initiative and Problem-Solving Ability

• "Have you ever tried to change something inside your organization? Impact isn't a mode you unlock when conditions are perfect — it's about noticing recurring problems, coming up with ideas to fix them, and actually taking initiative."
• "If you couldn't convince your boss at work, how are you going to convince a VC?"

6-3. Tenacity and Execution

• "If something is important to the company, you knock on every door until you find a solution. A little frustration and will to push through — that's where the path appears."
• "You need tenacity. Without it, things don't get done even inside a company."

7. Real-World Cases and the Best/Worst Engineers

7-1. Problem-Solving Case Studies

• "At Sungo, there was a dispute with Kakao and the KCSC over promotional messaging — we wrestled with it for three months and finally resolved it. I called the KISA officer in charge every single day until we got it sorted."
• "At Coupang, the return process wasn't documented, so I had a friend buy shoes and return them myself, then tracked the package all the way to the warehouse to map out the process."

7-2. The Worst Types of Engineers

• "Great at coding, but when we need to build an excavator, they keep building wheels. Efficiency is good, but every release is riddled with bugs."
• "Don't find a solution first and then wedge a problem into it. Find the problem first, then bring in the solution that fits."

8. The Essence of Software Development and How It's Changing

• "We've been constructing buildings since the pyramids, but software has far more uncertainty. You have to break it up and validate it step by step."
• "Software can be replicated, deleted mid-build, scaled up or down easily. You have to let go of the obsession with making it perfect all at once."
• "In software, what matters is shipping fast and getting people to actually use it. Using it is the point!"

9. Failure, Challenge, and a Growth Mindset

• "Can you keep trying without being afraid of failure or hardship?"
• "When I was young it was 'I can live on ramen in a goshiwon,' in the US it was 'I can get by on a five-dollar pizza' — that kind of anxiety didn't really get to me."
• "The world changes, but people's thinking doesn't seem to. Why does everyone have to be average, why does everyone have to live the same way? If you move fast, you don't have to run on the same track as everyone else."

10. Closing Remarks & Advice

• "Nobody knows how the world will change, and I don't think the question 'what will I do?' matters as much as 'how will I do it?' Focus on how you'll use your skills for whatever you choose, and things get simpler."
• "Like Steve Jobs said — 'Stay hungry, stay foolish.' Having curiosity and diving headfirst into things is good. You'll fail and hit walls, but you have to throw yourself at it to understand your role and the space where you can contribute."
• "The world is huge. Running on the same track as everyone else isn't the answer. Keep looking at your own life, thinking about how to approach it, and better outcomes will follow."

11. Outro & Space Introduction

• "This space distills 25 years of Olive Young. Growing like this is incredibly hard. A company that started with a single store becoming this — being a large company doesn't mean it's easy."
• "When Antler's great founders emerge, we'd love to welcome them, and if invested companies are a strategic fit, we do acquisitions too."
• "Thank you so much for watching today — we'll be back with even more interesting conversations next time!"
