🎯 From business card to CRM in 20 seconds: how I built an AI-powered app for a trade show

🔥

Do you know where most business cards you collect at a trade show end up?

In a drawer.

Or worse: in the pocket of a jacket you won't wear again until next year.

And with them, you lose business opportunities, conversation context, and that "hot lead" who seemed so interesting at the time.

The real problem

A client (BUSINESS GROUP) reached out with a very specific challenge: they'll be exhibiting at SICUR26 and wanted their sales team to capture leads quickly, without friction, and have those contacts land directly in their CRM (Clientify).

The traditional process looks like this:

You grab the card → 2 seconds
You put it in your pocket → 1 second
Back at the hotel, you manually enter it into the CRM → 3-5 minutes (if you even do it)
You try to remember what you talked about → impossible

Result: 70% of business cards never get processed. And those that do arrive without context.

The solution: a PWA with integrated AI

I built a mobile app (PWA) that does this:

📸 Take a photo of the card (front and back if needed)

🤖 AI extracts automatically: name, company, title, phone numbers, email, address, website, LinkedIn...

✏️ Verify the data in a form (in case the AI misses something)

📝 Add notes: "Interested in product X", "Call in March", "Spoke with Juan"

🚀 Send to CRM with one tap

Total time: 20 seconds.

And if there's no connection in the exhibition hall, no problem. The app saves everything offline and syncs automatically when the connection returns.

I did the math:

If you enter the data manually, each card takes about 4 minutes between finding it, opening the CRM, typing in the fields, and trying to remember what you talked about. At a trade show where you collect 50 cards, that's 3 hours and 20 minutes of administrative work.

With the app, the entire process takes 20 seconds per lead. Those same 50 contacts get processed in just 16 minutes.

Savings: over 3 hours that the sales rep can spend on what actually matters: selling.

And that's without counting:

Zero transcription errors
Conversation context captured in the moment
100% of leads processed (not the usual 30%)

How I built it

I used Google's ecosystem:

Google Stitch → to design all the app screens
Google Antigravity → to develop the complete PWA
Gemini 2.0 Flash → for image processing and AI-powered data extraction
Clientify API → to send leads to the client's CRM

Development time: less than a week.

Two years ago, this would have required a team of 3 people and 2 months of work.

What I love most about this project

It's not the technology. It's the real impact.

A sales rep at a trade show has valuable conversations all day long. But their job isn't to enter data into a CRM. Their job is to connect with people and close opportunities.

This app removes the friction between "meeting someone interesting" and "having them in the system ready for follow-up".

20 seconds and done.

Final thought

We're living in an incredible moment. The tools we have today allow us to solve real business problems in days, not months.

AI won't replace salespeople. But a salesperson with the right tools will always outperform one who's still stuffing business cards in their pocket.
