How Louis Corneloup Built His Newsletter to 300,000 Subscribers
How Corneloup Leveraged Reddit and beehiiv’s API To Scale His Newsletter

Situation:
Louis Corneloup, a 25-year-old entrepreneur from France, launched Techpresso, a daily AI and tech news newsletter, while completing his master’s thesis in Germany. He identified a gap in the French media landscape for engaging, digestible tech content and decided to create the newsletter he wished existed. With no brand or audience, he aimed to turn his passion into a career by building his own media company.
Challenge:
Corneloup started with zero subscribers, no marketing budget, and no technical infrastructure for large-scale distribution. His initial growth strategy on Reddit was effective but unsustainable—he faced multiple account and domain bans. Later, as subscriber numbers grew, he encountered significant deliverability and scalability issues while managing a self-built email infrastructure.
Solution:
Corneloup switched to beehiiv in 2023, drawn by its newly launched API, advanced deliverability tools, and scalable infrastructure. Key features he utilized included the beehiiv API for seamless distribution, Boosts for paid subscriber acquisition, automations for audience segmentation, and dedicated IP addresses. The platform eliminated his technical stress and allowed him to reclaim time while preparing to launch new publications.
Results:
- Scaled Techpresso from 0 to 300,000 subscribers in two years.
- Transitioned from DIY infrastructure to a stable, scalable platform with beehiiv.
- Plans to launch 9 new newsletters and deepen monetization with long-term partners.
“Now, I don’t worry about deliverability or IP issues… The time that I spent because of not being on the right platform is priceless.”
