How It Started...

📈 How It Started...

After graduating college with a business degree, I moved to Seoul and began teaching English in 2016. 

While working in Seoul I quickly discovered:

1: How kind, motivated, and hardworking Korean people are. I love working with people who have passion and purpose in their lives.

2: Many Koreans deserve much better in their careers. Too many talented people are stuck at jobs they don't really like with demanding bosses and tons of overtime work. Others have dreams of living/working abroad, but need to improve their English to do so.

3: A lot of English classes aren't very good. Whether they're too focused on grammar or general free talking, they don't get people the communication skills/confidence they need to level up their careers.

So while working at FastONE (a 비즈니스 영어 학원 in Gangnam) I began to develop my own style of lessons where Koreans could quickly improve their work-specific communication.

My system organized, work-specific classes were a huge hit, and I quickly became one of the most popular and highly-rated instructors at the entire school.

✅ Grant Sundbye: Business English Coaching ✅

April 2020 - December 2022

By the end of my contract at FastONE, I had a system of teaching that worked.

I was so impressed with the passionate clients I got to work with that I wanted to share my coaching with as many Koreans as possible.

So, I founded my own online business in 2020 with the goal of helping Koreans all over the world

unlock the fulfilling careers they deserve.

I took the best elements of my coaching at FastONE and added even more resources to create the ultimate coaching program for Koreans.

The Result? Business English Excellence

The personalized 12-week 1:1 business communication program designed to massively increase Koreans' English level, confidence, workplace communication, and global career opportunities.

⬇️ Over the Next 2.5 Years ⬇️

Over 100 incredible Koreans across all industries, English levels, and career stages took the Business English Excellence Program

From entry-level employees with big dreams to Founders of $50Mil+ startups and country managers of Fortune 500 companies.

I wrote a book on business communication that was published in 3 countries

Business English Excellence was so successful that around 8 months after launch a publishing company contacted me with an offer to write a business communication book.

The Concept: After spending 1000s of hours coaching 100s of Koreans, explain 150 of the most common English speaking mistakes Koreans make (plus how to fix them).

The book was published in October 2021 and was so successful that after selling thousands of copies in Korea, it was translated and published in both Taiwan and Vietnam in 2022.

I Reached the Top 1% of all Linkedin Users

I first reached the Top 1% in December 2020 and have maintained that ranking every month all the way to today.

Along the way, I've also gained over 43,000 followers across LinkedIn and YouTube.

Business English Excellence changed the lives of Koreans around the world

Many gained dream promotions at top global companies. Others improved their work communication more in a few months than years of traditional 학원 classes.

Over 90% of Koreans who completed the program either signed up for additional coaching or recommend my programs to their friends/colleagues.

I spent around $10,000 on coaching for myself

Learning everything I possibly could about marketing, sales, business communication, career development.

I've learned directly from some incredible entrepreneurs and business leaders (Career coaches with over 1 million online followers, bestselling authors on international leadership, millionaire entrepreneurs, and more).

I’ve incorporated all these lessons into my coaching programs and continued to make them better and better. I was the top instructor at FastONE, but I can say with confidence that I'm a much, much better teacher now than I was then.

Your career matters. You deserve to work with someone truly committed to helping you achieve something amazing.

🌎 Grant Sundbye: Career Coaching 🌎

Dec 2022 - Present

As my business grew, more and more Koreans wanted help writing their English resumes, preparing for interviews, and getting international job/grad school offers.

I also became more and more interested in expanding my services beyond business English coaching.

The entire reason my business exists is to help Koreans unlock international careers they love...

...so why not offer a new coaching program that does exactly that?!

So, I started learning everything I could about standing out in the global job market.

I took courses on resume and LinkedIn writing for jobseekers, the best messages to send hiring managers, and how to make a great impression in interviews.

I met directly with recruiters and hiring managers around the world to learn exactly what they look for in candidates.

I combined all of this information with my understanding of LinkedIn, business communication, Korean culture, and personal branding to create the Career Accelerator Program.

I designed this program with a single goal: Create the best coaching service in the world for any Korean hoping to develop their career internationally.

⬇️ Since December 2022, Career Accelerator clients have gotten jobs ⬇️

In 15 different countries.

At global industry leaders as well as fast-growing startups

With salaries up to $70,000/year MORE than their salaries in Korea

With fully-remote work options, great work cultures, and improved work-life balances

In 2023 & 2024, over 90% of all Career Accelerator clients earned at least one international job offer 🌎

Many of these clients had tried and failed to get jobs abroad previously.

Some had never lived abroad before.

Some needed VISA sponsorship.

Many were seriously questioning if their global career goals would ever happen.

With the right plan, your career goals are 100% possible.

The Career Accelerator system has been so effective that I’ve even been invited to American universities to give guest lectures on career development.

My Promise to you 🤝 (yes, you reading this right now)

Whether you become a long-time client, are a fellow entrepreneur, or just a LinkedIn connection, I want to benefit your life in some way.

I hope every program, course, and piece of content I create gives you valuable insight, inspires you to take action, and helps you unlock a life/career that you love.

Because you deserve to wake up Monday morning excited to go to a job that values you.

Frequently Asked Questions

Who is this program designed for?

This program is for you if:

1: You’re a Korean professional with at least a few years of work experience

2: Your English level is good enough that you can easily understand this page

3: You’re ready to take a major step forward in your career. You’re interested in getting the best job you possibly can abroad or at an international company in Korea, so you can earn more, get more fulfillment from your work, provide more for your family, and feel truly proud of yourself.

This program is not for you if:

1: Your English level isn't good enough to understand this page

2: You have urgent interviews coming up soon. In that case, just get my Interview Excellence Masterclass instead.

3: You’re not willing to invest in yourself and do the work. This will require some time and effort on your part, but the benefits will be 1000% worth it.

I'm not 100% sure what I want for my next job. Can I still join?

Absolutely! One of the first things we'll do at the start of this program is evaluate your strengths and desires to create some specific goals.

You'll gain much more career clarity as we move through this program.

However, if you're 100% lost and truly have no idea what you want next, it may not be the best time to work with me.

I'm interested in graduate schools. Can this program still work for me?

Definitely. It's already helped Koreans get into some of the best Master's, PhD, and post-doc programs in the world.

Why include so many videos and courses? Why can't we just do everything together in 1:1 sessions?

1: I spent hundreds of hours designing, writing, and creating the courses included in this program.

They are as organized, clear, and efficient as possible. They're even clearer than if I just explained the information to you in a live session together.

2: Just the video portion from the courses is around 20 hours of content.

It will likely take you several more hours to follow all the content from the courses to create your documents and plan all your interview answers.

If we did 100% of that together, we'd likely be spending around 40 hours of live sessions together, making this program significantly more expensive.

This is the absolute best option to provide an incredible, career changing service while also keeping this program at a price anyone can afford.

The video courses will serve as a fantastic guide to get you 80% of the way to having that perfect profile, resume, and interview strategy. We'll get you 100% of the way there when we meet for our 1:1 sessions.

How can I start/sign up?

Step 1: Fill out a consultation request form by clicking one of the blue buttons spread throughout this web page.

Step 2: I'll send you some additional information about the program to review before we have our consultation.

Step 3: We’ll have our consultation where I can learn more about your situation, give you some advice, and determine if you’re a good fit for this program.

If you’re a good fit, I’ll send you a secure private payment page where you can pay with any card you have.

If you’re not a good fit, I’ll still give you some advice and point you in the right direction.

When is the best time to start this program?

The best time to start is 3-5 months before you'd like to start working at a new job.

For example, if you're hoping to officially start work at a new job sometime in July or August, the best time to start this program would be around April.

It takes time to put your best self forward as a jobseeker, but is 100% worth it.

How many 1:1 sessions will we have together?

1: The purpose of this program is not for you to spend a specific amount of time with me. The purpose is to get you results.

I’m pretty flexible with the amount of time we actually spend together.

You’ll get 10 1:1 sessions with me that are usually 60 to 90 minutes long, but if we need to spend a little bit of extra time together, I’m happy to do that.

If you’re fully invested in your career goal, I am fully invested in helping you achieve it.

2: You’ll also be doing a lot more than just having those sessions with me.

You’ll go through all the courses included in this program outside of our class time and plan your documents/interview answers. This way, the time we do meet is as efficient and value filled as possible.

Outside of our sessions together, I’ll be totally available the entire 4 months to answer your questions, check in with you to see how things are going, and give you any additional support you need.

You will not be alone for any step of this process.

The total amount of time for you will probably be at least 3 hours of work per week, but everything will be planned, organized, and easy for you to follow.

Can I ask some other questions that aren't listed here?

Sure! I'll be happy to answer all your questions in our consultation.

Feel free to write any questions you have in your consultation request form.
