Joining me today is John Li, the co-founder of PickFu, a powerful consumer-feedback platform that helps e-commerce sellers, authors, app developers, and marketers make smarter, data-driven decisions.
Before launching PickFu, John spent years at Microsoft as a software engineer and program manager but his entrepreneurial curiosity led him to create a simple tool to test ideas with real people.
That tool evolved into PickFu, now trusted by tens of thousands of Amazon sellers and brands to validate product images, packaging, and listings before they go live, saving them from costly mistakes and giving them the confidence to scale.
John is a true advocate for taking the guesswork out of e-commerce growth, and today, he’s here to share how feedback-driven testing can help you turn more browsers into buyers, and more ideas into 8-figure successes.
