About Jamble

A live marketplace serving a community of 40,000+ collectors

Jamble is Brazil’s collectibles marketplace, where sellers go live to sell fan favorites — from Pokémon TCG and Hot Wheels to Magic: The Gathering, sports cards, action figures, and other rare finds — to an active community of 40,000+ passionate collectors.

Every transaction happens live: a seller hosts a show to present collectibles, talks through its condition, authenticity, and rarity, while buyers watch, chat, and buy in real time. Discovery, trust, community, and commerce all happen within a single live experience.

The Problem

Recreating the energy of a trading floor or a collectors’ meetup online

Collectibles are inherently visual. Buyers need to inspect condition, authenticity, and fine details before making a purchase—something static photos can't fully capture.

Jamble needed a live experience that recreated the trust and excitement of an in-person collectibles marketplace. Buyers had to see every detail clearly, ask questions in real time, and make purchasing decisions with confidence.

Any latency, poor video quality, or audio issues would interrupt the buying experience and reduce trust at the exact moment a purchase was being made.

Results and ROI

Live shows that keep collectors watching, engaging, and buying

Agora powers every live show on Jamble, so the impact is the business itself. Top sellers stream for about four hours per show, drawing close to 850 viewers each, and each viewer stays for nearly eight minutes on average. These are the hours when the excitement unfolds — when people engage, sellers showcase their rarities, and buyers experience the thrill of owning new collectibles.

With Agora’s SDKs helping Jamble complete production integration in under two weeks, Jamble could focus on building its payment experiences on top of the stream and growing the community to its now active base of over 3,000 sellers and 40,000 collectors.
