Dave : Generative AI Assistant for Smart, Human-Like Financial Support

Fintech

Dave – Generative AI Customer Service Assistant (DaveGPT)

Dave partnered with us to develop DaveGPT, a conversational AI assistant that delivers instant, personalized support for users managing finances. Built with GPT-based architecture, the assistant helps users track spending, manage budgets, and resolve account-related queries autonomously. It understands natural language and provides answers that are contextually accurate and human-like. Integrated with user transaction data, it proactively alerts customers about overdrafts, fees, or unusual activity. The result is a smarter banking experience that reduced support tickets while enhancing financial wellness. DaveGPT is now a core part of their customer engagement strategy.

Project Overview

Client: Dave (Public fintech platform serving 10M+ users in the U.S.)
Challenge: High customer support volume + limited personalization in financial guidance
Goal: Build a GPT-powered assistant to:
- Automate budget and spending-related support via chat
- Resolve account issues, FAQs, and alerts autonomously
- Personalize financial interactions using live user transaction data
Team: 8 (2 NLP Engineers, 3 Backend Devs, 2 Data Analysts, 1 QA Lead)
Timeline: 5.5 months (MVP → Live Testing → Full Integration in Dave App)

“DaveGPT is more than a support agent—it’s a financial ally. With GenX, we brought empathy, intelligence, and automation into one unified assistant.”

Head of AI Products, Dave
