CardSeer

CardSeer is a platform for buying, selling, sharing, and organizing trading cards with an interactive story campaign. In practice that means designing and building iOS and Android apps.

Who is it for? Mostly businesses launching or rebuilding an app. They also list Collectibles, so expect those to show up in the feature set. They are a very small team, 1 to 10 people, which usually shapes who they work with. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

CardSeer is based in Phoenix, Arizona. Their site is cardseer.com.

Before you commit, look at portfolio quality, app store experience, and maintenance terms. Get the renewal terms in writing before the first invoice.
