Across its catalog the studio has worked with 1 publisher, including DANGEN Entertainment. indielist tracks releases from Mantis starting in 2025. This profile sits inside indielist's relationship graph of studios, publishers, and games, so players can find more titles from the same team, developers can compare portfolios and team sizes against peers, and investors can trace which publishers and genres the studio works across. Where Steam review data is available, indielist also publishes a transparent, white-box sales estimate for each of the studio's games, showing the full Boxleiter factor breakdown rather than a single black-box number, so the commercial picture behind Mantis can be audited rather than taken on trust.

On the business side, Mantis has shipped with 1 publisher (DANGEN Entertainment), and indielist maps each of those relationships as an edge in its studio-to-publisher-to-game graph. That matters to two audiences in particular: an investor can trace which labels have backed this studio and how that roster has changed over time, while a developer can see which publishers are already comfortable signing work in the studio's genres before deciding where to send a pitch. This is the kind of sourcing intelligence that is slow and tedious to reconstruct from Steam store pages alone, because the storefront never exposes who introduced whom. Each linked publisher page in turn lists its full roster, deal tier, and current submission status, so the network around Mantis can be walked outward in either direction rather than read as a flat, disconnected list.
