Colorado-based hobbyDB is offering collectors the opportunity to own shares in the growing hobby and collectibles data service.

Nearly 600,000 users already use hobbyDB to track, price, and sell their collections, and the company is already helping power features of third-party apps, such as the Funko Collection Tracker. Using Wefunder, hobbyDB is selling stock in the company with an entry-level investment set at $220 for 200 shares.  The company says that it’s raised more than $4.3 million since its founding, and that it’s seeking around 500 investor “evangelists” for this round.

A detailed pitch deck offered through Wefunder showcases the hobbyDB strategy of growing its database to encompass all collectibles and fandoms while monetizing through marketplace transactions, affiliate revenue, collectible insurance packages, and offering market insights for brands.

At press time, the Wefunder campaign has $23,761 of a minimum funding goal of $80,000. The ultimate goal is to raise a total of $1,070,000 during the campaign.
