Are Students of Quantum Growth Successful?

There are many students of Quantum Growth that have found success in their businesses using what they learned from the course. There are tons of testimonials on the KingKong website of satisfied clients and students. Reviews for KingKong are mostly negative on Trustpilot with a rating of 2.2/5 with 74% of reviews being 1-star. The complaints are from unsatisfied clients of KingKong agency and customers who availed the “free” Sell Like Crazy book and got overcharged with the promos. There aren’t any reviews directed at the course.

There are only a couple of reviews for the Quantum Growth course. This student, Bruce Slater, praised the course and how the lessons improved his business. He did not provide any specifics or figures on how much his business improved, however. I could not find any success stories with real-world examples from students of the course outside of the official website.

This review by a client of KingKong agency complained about the unsatisfactory marketing performance of the agency. He explained that hiring an in-house marketing manager and web designer was more efficient that working with KingKong. In my opinion, Quantum Growth should reflect Sabri's digital marketing agency business. If KingKong agency is full of complaints, this sets the wrong expectation on what he teaches in his course and how he will treat his students.

What Is Sell Like Crazy?

Sell Like Crazy is a sales and digital marketing guidebook by Sabri Suby that provides invaluable insights on generating leads and creating irresistible offers. The book includes practical and actionable advice on marketing optimization. In the book, Sabri Suby outlines his 8-phase selling strategy, including his steps on how to create an irresistible “Godfather” offer. The first module of Quantum Growth covers the contents of the book.

How Sabri Suby Turned $50 to $100,000  

Background of the Story

Sabri Suby, the founder of King Kong, a highly successful digital marketing agency in Australia. He grew up in Byron Bay, was raised by a single mother, and started working at a young age to help with the family's finances. Once, he made $80 from busking. At that time, this amount was already a huge help for his family. Since that experience, he became very interested in entrepreneurship and later pursued a sales career. 

Challenges Sabri Faced

Sabri wasn't a good salesperson when he started, but he quickly learned the business and became a top performer. His first business was a water filter company. This taught him valuable lessons in business, especially in demand and market needs.

His venture into the digital marketing world began when a prospect asked for SEO services, which he initially didn't offer. He explored this industry and learned the business from scratch. This wasn't easy for Sabri. He faced financial constraints and intense competition. He had to work long hours and face multiple rejections as a newbie. 

How He Turned $50 to $100,000

Sabri began his agency with just $50, an old computer, and a lot of cold calling. Despite initial rejections, he persisted and eventually clients began to trust him. He emphasized the importance of having the right mindset and focusing on core business fundamentals. His business approach prioritizes cash flow, high margins, and mastering customer acquisition through various digital channels.

Is a Digital Marketing Agency Worth It in 2024?

Digital marketing agency is a highly saturated business in 2024. With the amount of easily accessible digital marketing training and the easy entry into the industry, it is hard for new agencies to breakthrough and find success. Potential clients would often prefer agencies that have a long proven record of delivering success. As a new agency, you will need to spend a lot of time and effort building your reputation. To get clients early on, you may need to offer your services for free or at a cheap price.

What a lot of courses don’t tell you early on is that you need to first market your own agency by spending thousands of dollars to invest in PPC advertising, lead generation, sales funnel, etc which creates high risks. Alternatively, working for a digital marketing agency can be a good way to get much needed experience and build your portfolio without taking risks. Creating passive income with a digital marketing agency requires you to have an already established and stable agency so you can start outsourcing most of the work.

Create Low-Cost Scalable Passive Income With Local Lead Generation

Local lead generation is my recommended low-cost business model that creates passive income. As a type of digital real estate where you are the landlord, you earn predictable passive income by ranking a website on Google and renting it out to local businesses. You don’t need to worry about running paid advertising or marketing campaigns. It costs an initial investment of as little as $500 to get started and about $30 a month to maintain. Once your website is ranked and rented, you can earn up $500-$2,000+ a month. A site can stay ranked on Google for years, meaning once you launch your site, it’s basically hands-free.

Scaling a digital marketing agency means a lot of outsourcing, which increases your operational costs. Scaling a local lead generation business is as simple as repeating the process of rank and rent. There is no limit to how many websites you can create. This high scalability and sustainability is why local lead generation is my recommended business model to create time and financial freedom.
