Hi YC! We're Jude & Daniel, and we’ve built Carousel - an AI assistant that transforms how people work in Excel.

The Problem: Excel is Powerful but Painful

Excel remains the universal language of business despite being:

• Time-consuming: Building models takes hours of manual work
• Error-prone: Manual data entry and complex formulas lead to mistakes
• Intimidating: Mastering Excel formulas takes years

Professionals spend countless hours battling spreadsheets instead of focusing on decision-making.

Our Solution: Your Personal Excel Intern

Carousel is an AI assistant that builds spreadsheets & models in minutes, not hours.

We've built four core features:

🤖 Carousel Chat - Build complete multi-tab models from scratch with conversational prompts. No Excel expertise required. Models that took hours to spin up now take minutes.

⚡ Quick Fix - Select any range, hit Ctrl+Enter, and describe what you want. Format tables, add analytics, or restructure data instantly.

🔍 Model Walkthrough - Understand complex formulas in plain English. Model Walkthrough rewrites formulas by swapping cell references like S&U_Sheet!K7 with Transaction Closing Costs (4%).

📄 File Context - Stop doing manual data entry. Carousel pulls information from your documents and puts them into your Excel file live, complete with automatic source citations.

Unlike your last intern, Carousel is competent, doesn’t complain when asked to fix spreadsheet formatting, and doesn’t need a return offer.

Carousel is what Microsoft’s Copilot for Excel promised to be.

Who's It Made For?

Carousel is designed for anyone who spends significant time in Excel:

• Financial analysts building complex financial models
• Marketing managers analyzing campaign performance data
• Operations leaders creating forecasts and tracking KPIs
• Product managers organizing feature roadmaps
• Scientists analyzing experimental data
• Consultants preparing client deliverables

Why We Made Carousel

Excel hasn't fundamentally changed in decades, yet it remains central to how teams & businesses operate.

We built Carousel to bridge the gap between Excel's insane professional capabilities and its usability challenges.
