Why we're here
Collectibles businesses have outgrown disconnected spreadsheets, repetitive listing tools, and inventory that lives in too many places. Mascot connects the work behind every sale, from intake to fulfillment, so sellers can operate with confidence.
Our goal is straightforward: make sophisticated commerce accessible to every seller, without adding complexity to their day.

Leadership
Founder & Chief Executive Officer
View Guinio on LinkedInAs a founder and CEO of Mascot, my vision has always been to give collectors, dealers, shop owners, and investors a platform to manage, distribute, and sell their collectibles across the marketplaces that matter most. We have always believed that the more exposure your products receive, the greater the opportunity to connect with buyers, grow your business, and get the most out of your collection.
We have come a long way over the last couple of years, and we are just getting started. I am incredibly proud of what our team has built and grateful to everyone who has trusted Mascot along the way. We look forward to continuing to serve you, listening to your feedback, and growing alongside the hobby. Our goal is simple: build the tools and technology that make it easier to buy, sell, manage, and grow in the collectibles industry.
