I Built a Data Analytics SaaS in 10 Hours (Not 30 Minutes) - Full Demo

In this episode of TwoSetAI, Mehdi walks through how he built a CSV-to-insights tool for marketing agencies using ChatGPT and Claude Code. Watch as he demos the live product, shares practical Claude Code tips, and gets real about development timelines - spoiling the "build a SaaS in 30 minutes" myth.

We dive into the technical stack (FastAPI, React, Supabase, Clerk), discuss the hallucination problem in data analytics tools, and explore the journey from PRD to production-ready micro-SaaS. Mehdi also reveals his process: using ChatGPT for ideation and competitive research, Claude for implementation, and v0 for the landing page.

Key topics covered:

• Building a data analytics SaaS with AI assistance
• Claude Code tips and tricks for efficient development
• Handling CSV data cleaning and preprocessing
• SQL query generation and visualization
• The reality of AI-assisted development timelines
• Addressing hallucination in text-to-SQL applications
