Are you struggling to get by in B2B sales on your own?

Sales is a field where you always have to prove yourself with numbers. Yet there aren’t many opportunities to properly learn 'how to do it well. I was the same way.


Hello! I'm Park Jumin, CEO of Frontier Biz 👋

To professionalize corporate sales in South Korea, I write and lecture as a corporate sales training expert and Korea’s first cold-calling expert.

I began my career in 1996 on Samsung Electronics' advertising planning team, and after being assigned to the sales department in the wake of the IMF crisis, I have continued a sales career spanning nearly 30 years. For 12 years at Samsung Electronics, I faithfully handled distribution, direct, and solution sales as an IT sales representative at the customer interface, specializing in new business development sales that others were reluctant to pursue and receiving the '100 Salespeople Who Made Samsung Electronics Shine Award'.

Later, as the head of sales at a small and medium-sized enterprise and the founder of my own business, I gained extensive experience in sales at various levels—as a practitioner, manager, and executive—working across both B2C and B2B. Building on these 20 years of hands-on experience, I spent the past 10 years researching world-class sales content and authored five books on sales, including 『Promise』, 『Win with True B2B Sales』, and 『Distinctive Sales: They Sell Differently』. I have conducted training and coaching for countless companies both in Korea and abroad, and have consistently received the highest ratings at every company where I have lectured.


These are the things I want to share with you through this course.

1️⃣ 'Why expert sales now'—we'll show you the data.

Today, customers are hesitating to make purchases because their fear of failure (FOMU) is greater than their fear of missing out (FOMO). To overcome this, you need to strengthen the sales representative’s expertise rather than focus on price and quality. I’ll take a close look at the recent changes in the buying environment and explain in detail what expertise customers want from sales representatives.

2️⃣ We’ll help you clearly grasp the core concepts of successful B2B sales.

The difference between 'Wins' and 'Results', the essence of realizing customer value, the ability to provide the selective information customers want, trust capital built through expertise, consistency, and authenticity, and even the types of sustainable sales representatives. We’ll change the way you see sales through materials and data validated in 30 years of sales experience, Samsung Electronics’ pioneering sales cases, and various practical sales insights.

3️⃣ We will help you find confidence and vision in your work.

In B2B sales, you can work confidently and enjoyably when you grow into a strategic sales marketer as a Trusted Business Advisor—a trusted business advisor, not merely a salesperson. I’ll explain in detail why, along with supporting evidence.


We created this with people like you in mind 💁‍♂️

😢 I'm good at explaining the product, but I can't close the deal

You explain the product smoothly in front of customers, but when it’s time to sign the contract, you keep missing the opportunity.

📌 Deals usually fall through not because of the price, but because of 'anxiety'. You’ll understand why customers’ anxiety resurfaces at the moment of signing and why a competitive mindset is essential for staying focused until you achieve results.

😵‍💫 I'm afraid of developing new clients

You end up managing only existing customers, and you’re afraid to call new customers first (cold calling). It’s unsettling to feel like you’re stuck maintaining the status quo.

📌 Maintaining the status quo is the biggest enemy of sales performance. Understand why you need to step outside your comfort zone and develop a mindset that allows you to confidently pursue new business.

🤔 I'm exhausted from competing on price alone

It ultimately turns into a price war, leaving you feeling drained without gaining anything.

📌 What customers truly want isn’t a low price but 'trust'. You’ll gain the perspective to understand why the trust capital built through expertise, consistency, and sincerity beats price competition.


What You’ll Gain from This Course 💎

1. Your perspective on sales will change

Sales isn’t simply about selling a product; it’s about solving the customer’s problems 'better'. You’ll develop the perspective needed to become a 'game changer' who changes how customers see things.


2. You will know which areas of sales skills you need

The point where sales gets stuck differs from person to person. Some people struggle because they can’t meet new customers, while others make it to the meeting but can’t close the deal. Once you build a strong foundation in mindset through this course, you’ll be able to diagnose for yourself which area of skills you need right now.

  • If you’re not gaining new customers and are afraid of cold calls → New customer prospecting skills (Coming soon)

  • If you have meetings but they don’t lead to contracts → sales consulting skills (coming soon)

  • If you want to win large deals and complex sales → Strategic Selling Skills (Coming soon)

This course is the starting point. Once you understand where you’re getting stuck, it will become clear what you need to learn next.

Sharing based on real cases experienced in the field

Reassessing the mindset based on a clear definition
