Inspiration

We build websites for small businesses in Lahore. Finding the right ones was always the hard part. A café with no website will never post "looking for a developer." Existing lead tools either make up contacts with AI or depend on expensive paid APIs. We wanted a tool that finds real businesses and shows the proof for every claim.

What it does

LeadDesk is a local AI assistant for finding prospects. You describe your product and pick a location, and it:

• Finds real businesses from open map data (OpenStreetMap and Overture Maps)
• Reads their websites and spots gaps, such as no mobile layout, no online ordering or an outdated site
• Checks phone numbers and emails across several sources
• Uses a local AI model to explain why each business may need your product, citing the evidence for every reason

How we built it

• Backend: Python, SQLite, DuckDB
• Frontend: React and Vite
• AI: Ollama running local models, with NVIDIA GPU support
• Search: self-hosted SearXNG

Rules run before AI. The model only sees a numbered list of collected facts, and every reason must cite one of them. A second "verifier" pass checks each reason and can only lower confidence, never raise it.

Challenges we ran into

• Small AI models often overstated facts, so we added automatic checks that flag unsupported claims.
• Chains with many branches got mixed up, for example a Lahore café showing Karachi phone numbers. We fixed this with identity cross-checks.
• Open map data had few phone numbers, so we combined several data sources.

Accomplishments that we're proud of

• Real-estate search in Gulberg, Lahore went from 0 to 95 businesses, 77 of them with phone numbers.
• Every claim links back to its source.
• 350+ automated tests.
• Fully local and private, with no paid APIs.

What we learned

• AI is most useful when it explains facts, not when it invents them.
• Open data becomes powerful when you combine sources.
• Showing the evidence builds trust.
