“In search of growth, we asked around for a hands-on Amazon expert who would “sweat the details” and help bring us to the next level. Gene quickly identified ways to significantly increase our ad spend and ad-generated sales at a highly efficient ACoS. Best of all, results have not flattened out as we complete Year 2.  Gene continues to push the envelope and find new ways to deliver growth. Gene has gained the highest respect from everyone on my team and I would happily recommend him to any client who is looking to grow their Amazon sales.”

Very quickly we saw a large jump in sales which has continued to this day. Highly recommend his services to anyone looking for a boost in sales.”

Matthew Hodge

“After finding that Amazon could be a significant part of our commercialization strategy we quickly realized an expert was needed to ensure we were providing a positive experience for our customers. Spot-On was able to mix in a perfect blend of e-commerce expertise and Amazon insight to give our products a strong brand presence while making it easy for customers to shop. We are sincerely grateful to Gene for his knowledge, expertise, but most importantly treating our business as if it were his.”

“We engaged Gene to help us with our nascent Amazon third-party seller business. This was our first Holiday season selling on Amazon and Gene offered us strategic guidance as well as tactical initiatives to boost the business. It worked! I especially appreciated his tactical advice and his sense of urgency to get us ready for the Holiday season. He has an excellent combination of creative vision and analytical aptitude. He was accessible and easy to work with.”

I have found Gene to be very focused on sales and margin growth.  He has a great deal of expertise on Amazon but is also a great resource on Digital Marketing across multiple channels.  He is easy to work with and will help your business tremendously.”

Gene has continuously guided us in becoming a successful 3-P seller on Amazon. His knowledge and expertise has given us confidence in the products we plan to launch. He has supported and showed our team what is needed to be successful on Amazon. We greatly appreciate Gene’s knowledge and he is always a pleasure to work with.

Phiona Ercolamento
Product Manager, LiDestri Food & Drink  

“In the world of Amazon and E-commerce there are a lot of consultants and business service providers. I have worked with Gene for several years with multiple clients.  Gene is more than a consultant or service provider, he is a strategic partner who brings knowledge, experience, commitment and focus to every relationship.  I not only recommend him but strongly encourage anyone needing a strong strategic partner in their Amazon business to add Gene to their team if they can.
