Q&A with Sabrina Sadiq, CEO of Luxury Promise

Chiswick Auctions is excited to collaborate with Luxury Promise, the global online marketplace for premium and hard-to-find designer bags. Together with CEO Sabrina Sadiq, we have curated a 50-piece collection featuring rare and exotic Hermès handbags in unique and special-order colourways. Ahead of the sale, we spoke to Sabrina about her journey, the future of AI in resale, and her passion for democratising luxury.

How did you start Luxury Promise?

Luxury Promise was born out of a genuine love for handbags. After years of working as a luxury consultant, I noticed two major gaps in the market. First, there was nowhere to find out the real value of your wardrobe. Second, there was no truly global platform for buying and selling pre-loved luxury, especially in underserved regions. Luxury Promise was created to bridge those gaps.

Who is the Luxury Promise customer?

We believe in making luxury accessible. Our customers come from around the world, from all walks of life. Through digital innovation, we allow anyone to buy or sell designer items from the comfort of their home. That accessibility is at the heart of our mission.

How have you incorporated Artificial Intelligence (AI) into your business?

Before founding Luxury Promise, I launched one of Europe’s first schools of authentication. We collected a vast amount of data on how to price and authenticate luxury goods. With that information, we built an AI tool to support accuracy in valuations and pricing. It is not about replacing people, it is about enabling them with better technology.

Can AI replace human authenticators?

No, it cannot. Our authentication process uses AI alongside expert human knowledge. Every item goes through a triple-check process, including manual authentication and an AI review for both pricing and authenticity. It is a tool to support, not replace, our team.

Is the second-hand market overtaking traditional retail?

Absolutely. For many consumers, second-hand is now their first choice. Sustainability is key, especially for younger generations who are focused on value and the environment. Buying pre-loved designer pieces gives items a longer life, offers better value, and supports conscious consumption. Many luxury items also prove to be strong investments over time.

Why did you choose to work with Chiswick Auctions?

It was important for me to combine the tradition of a respected auction house with the innovation of a modern resale platform. Luxury should feel like an experience. This collaboration allows us to offer that blend, bringing together technology and heritage.
