Cardio is a digital card built for the way we connect today—clean, fast, and always on. No apps, no printing, just one smart link or scan that shares your professional details in seconds.
I’m usually the data guy who working behind the scenes, but today I’m stepping out to share something I built with my partner, @cindyaffandi (she’s the design brain and I’m the code guy)
Cardio started with a problem that felt small, but kept coming up:
You meet someone cool, have a great conversation... and a few days later, they forget who you are. You gave them your number, maybe even a card, but it didn't stick.
So we built Cardio: a simple, clean way to make sure you're the one they remember.
It lets you share everything about you in one smart link or QR code, your name, role, socials, contact info, and anything else you want to be known for.
Here’s what it does:
✅ Instantly saves your contact into someone’s phone (no app needed)
✏️ Edit your info anytime, it updates automatically
🔗 One smart link or QR with all your details
No downloads, no apps. Just one clean, modern way to help people remember you.
We've seen people use it at events, in interviews, pitches, even on their resumes and email signatures. It's been incredible to see it actually work.
If you’ve ever had someone forget your name 5 minutes after meeting... or wondered if they ever followed up because they couldn't find your info again... Cardio is for you.
Would love to hear what you think. Thanks for reading 💛

Who hunted Cardio?
Cardio was hunted by Clement. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
