Entrepreneur, Amazon Seller, Educator & Builder
I’m Crescent Kao, the creator of Free Amazon Tools. I built this site to help Amazon sellers make better decisions with simple, free calculators and resources.
My background spans entrepreneurship, software, online communities, Amazon private label, education, and even motorsports. I’ve spent years building businesses online and sharing what I learn with other entrepreneurs.
Amazon Education
I share Amazon FBA, private label, and entrepreneurship strategies through YouTube, online training, and seller communities.
Software & Tools
I started building online businesses in college and have continued creating software, communities, and tools for entrepreneurs.
Real-World Experience
Free Amazon Tools is built from practical seller experience, not theory — with a focus on helping sellers save time and increase profits.
My Story
I grew up in Vancouver, Canada and later attended Western Washington University, where I earned a Bachelor of Science in Industrial Design. While working toward a second degree in Computer Science, I started my first online business in the gaming industry.
That business grew into a large online community with hundreds of thousands of players and eventually led to the software development company I still own and operate today.
Over the years, I took my experience in software, online communities, and digital business and applied it to Amazon private label. That journey led me to teaching other sellers how to start and grow their own Amazon businesses.
Today, I continue to build tools, tutorials, and resources for Amazon sellers who want practical help without unnecessary complexity.
Why I Created Free Amazon Tools
Selling on Amazon involves a lot of numbers: fees, profit margins, PPC costs, barcodes, BSR estimates, storage costs, ROI, and more.
Most sellers either guess, overcomplicate the process, or pay for software before they understand the basics. I wanted to create a free resource where sellers could quickly calculate the most important numbers and make smarter decisions.
Free Amazon Tools exists to give sellers simple, useful tools that help them understand their numbers before making product, pricing, and advertising decisions.
My Vision
My goal is to help entrepreneurs escape the 9–5 grind, build real businesses, and move closer to financial freedom.
Whether you are researching your first product or optimizing an existing Amazon business, I hope these tools help you make clearer, more confident decisions.
