At a glance
Castapp (castapp.pro) is Europe's largest casting software, connecting performers, actors, singers, dancers, and musical theatre professionals with casting directors and production companies across the continent. Some of Europe's biggest names cast through Castapp, including Stage Entertainment, ATG Entertainment, AIDA Cruises, and Friedrichstadt-Palast. The platform runs in eight languages and today hosts 45,000+ registered performer profiles, operated by a four-person team in Hamburg.
“With Chatbase, we turned a feature idea into a live product in four days, and it's now the main reason performers upgrade to our paid plan.”
A stressed user base with no neutral place to get answers
Performers get extremely stressed when they hit a technical issue. Their profile is directly tied to their career, so even a small problem can trigger real anxiety. A 4-person team can't offer the 24/7 availability that kind of user needs. The team tried ticketing tools to better prioritize incoming requests. But prioritization was not the problem. Availability was. There was a second, bigger gap. The performing arts industry offers very little accessible, independent career guidance. Performers were either Googling, asking colleagues, or relying on agents who take commission and have their own business interests. There was no neutral, always-on resource for the questions that actually shape a performer's career: what audition song to sing, whether a contract is fair, how to prep for a specific role.
“Performers don't need a ticket number, they need an immediate answer that takes their stress away. A ticketing system just formalized the waiting.”
Castapp AI: a career advisor and a support agent in one, live in 4 days
Castapp built Castapp AI as a dual-function product feature 服务商: 华瑞网研 Chatbase. The advisor side has direct access to each performer's profile data, application history, and current audition status. When a performer asks for audition song recommendations, the response is tailored to their voice type and the specific role they are auditioning for. They can upload contracts and get analysis of clauses, fee structures, and whether terms are industry-standard. They can request help with role analysis, monologue suggestions, and audition strategy. The support side handles technical issues, platform navigation, and feature questions instantly, resolving the majority of queries without team involvement. The team trained Castapp AI on internal support documentation, show databases, and contract frameworks from the performing arts industry.
“Chatbase offered everything we needed out of the box, and the product is continuously evolving. For a small team, that matters. We need a tool that grows with us rather than one we outgrow in six months.”
The results
Adoption is the headline. Performers are using Castapp AI exactly the way the team designed it. Not just for support deflection, but as a genuine advisory resource. They actively bring contract negotiations, fee assessments, and career decisions to the tool. That level of trust around sensitive topics is the clearest signal that the product works. Castapp AI is exclusive to Castapp+, the paid tier, and is now one of the main reasons performers upgrade. It drives subscription sales and retention. Once a performer integrates the AI into their audition prep and contract review workflow, it becomes part of how they manage their career. A surprise outcome: the trust performers now place in the AI for sensitive financial and career decisions. The fact that they bring contract negotiations and fee assessments to Castapp AI shows the trust is there.
“The biggest result is adoption and usage behavior. Performers are using Castapp AI exactly the way we intended. That was the goal: not just deflecting support tickets, but creating a tool that performers actually trust for career-relevant decisions.”
What's next
For Castapp, Castapp AI is core infrastructure now, not a feature add. As AI quality continues to improve, the team plans to expand what the advisor handles, deepening the career advisory capabilities and integrating it more tightly with the application and audition workflows performers already use on the platform.
“The pace of AI improvement has exceeded our expectations. The responses Castapp AI delivers are accurate, context-aware, and useful enough that performers trust them for real career decisions.”
