Hi, it's William, co-founder and CTO of Cardynale.

In the photo I am with Antoine, my associate (in the center) and Julien, our mentor (on the left).

Today, I wanted to tell you a little more about this crazy year than summer 2024 for the company. Maybe it can inspire some, help others.

So let's go, let's rewind!

Back in January 2024

A year ago, Antoine and I launched Cardynale, a digital business card solution. Today, we are celebrating this important first step and want to share our journey with you.

For those who don't know us yet, Cardynale is the easiest solution for exchanging contact details during physical meetings.

Our platform is used by freelancers, teams and businesses to expand their network and develop their business.

It all started in June 2023, while Antoine and I were still students at the École des Mines in Nancy. In February 2024, we started working on Cardynale full time.

Today, we are a small independent team based in France.

A year later, we are proud to announce that 11,800 people are using Cardynale to exchange business contact information.

  • 15,500 digital business cards generated
  • 240,000 card uses

To improve this we released:
- The templates,
- improved the sidebar,
- the teams,
- The v2 mobile application,
- The email signature,
- The animation,
- contents,
- Field blocking,
- Make integration,
- Google sign-in.

Recruiting is hard.

After a first entrepreneurial experience (JustOneCard), we knew what we did not want to replicate: a large team composed only of apprentices and interns. Without a mentor to guide them, it seemed counterproductive.

We therefore decided to recruit only experienced profiles (more than 5 years of experience). Our goals were clear:

  • Have autonomous and responsible pillars.
  • Save time by avoiding managing juniors.
  • Develop skills more quickly thanks to their expertise.

We called on a hunting firm to recruit 3 profiles:

  • Business Developer
  • Full-Stack Engineer
  • Growth Manager

Balance sheet? Over 4 trial periods:

  • 1 validated,
  • 1 in progress,
  • 2 have been broken.

Making and building are two strictly distinct skills. Someone can be very good at improving an existing system and at the same time not knowing how to set up a system.


Thus, two profiles seem to have their place in startups: those who have already built before and those who perform extremely well and who now want to build with their skills.

Simple > Complicated

The best decision we made? Simplifying our offer.

The offer in June 2024:

  • Solo package.
  • Team package (price per user).
  • Commercial license add-on (specific rate per user).

The offer in September 2024:

  • Business package (single rate per user).

The result: huge time savings on calls, sales cycles, documentation, and implementation.

Focus on one channel

We thought we needed to diversify across many channels: Facebook Ads, LinkedIn Ads, LinkedIn Ads, YouTube, event sponsorship, cold email, cold call... But we quickly realized that it was better to focus our efforts.

Our main channel today: the SEO.

We continue to optimize it with:

  • Original content,
  • Sponsoring articles,
  • Improving the structure of the site.

As we raise our glass to this first year, we're incredibly proud of how far we've come and excited to see what the future holds.

A huge thank you to everyone who has supported us from the start!
