The company needed to translate an evolving product vision into a scalable application. Its nontechnical CEO also needed an engineering partner who could define the architecture and own development from initial requirements through deployment.
Solution
End-to-end App Development
Toptal built the mobile application in Flutter and back end in Firebase, using an iterative process to translate evolving business requirements into technical solutions and production features.
Context-aware AI Experience
A RAG approach gave the app an LLM-powered experience that could retrieve relevant company-specific context when answering users’ financial questions.
Outcome
Production App Launched
The company progressed from a product concept to a functioning production application without first building a full internal engineering team.
AI Capabilities Delivered
The completed platform combined mobile, back end, and AI functionality, giving users an interactive way to ask financial questions and providing the company with a technical foundation for continued product development.
