But like most creators, he was building on rented land: platforms change algorithms, restrict monetization, and can disappear overnight. To own the relationship with his audience and deliver consistent value, he launched a weekly newsletter on beehiiv in February 2023. ### **Challenge:** Social reach wasn’t the issue. Sustainability was. - He needed a channel he controlled, not one dependent on algorithm shifts. - He wanted a system to reliably convert social followers into subscribers. - He needed monetization that didn’t require constant sponsor outreach. - He wanted to maintain strong engagement as the list scaled. ### **Solution:** He built the newsletter on beehiiv and used a simple funnel: social content → newsletter CTA → instant value → consistent weekly sends. Key tactics and beehiiv features: - **Top-of-funnel from X:** With ~194K followers, he drove early signups fast and hit **2,000+ subscribers in the first month**. - **Lead magnet for immediate value:** New subscribers received a guide (“25 Stock Terms Every Investor Needs To Know”). - **Monetization built in:** - **Boosts** to earn revenue from signups - **Ad Network** to fill ad slots without chasing sponsors - **Paid subscriptions** to test premium membership demand - **Engagement maintenance:** He kept the newsletter valuable and predictable, supporting an **~47% open rate** at scale. ### **Results:** Within 12 months, the newsletter reached **14,500+ subscribers**, and later grew to **17,000+ subscribers**. Monetization became diversified and repeatable: - **Boosts:** revenue tied to subscriber acquisition - **Ads:** consistent ad opportunities surfaced through beehiiv - **Subscriptions:** early traction with ~30 paid members (monthly/yearly) The result was an owned channel that converts attention into durable distribution—and revenue. ### Takeaway The Decade Investor’s playbook is simple and repeatable: - Use social as the acquisition engine - Offer immediate value at signup - Publish consistently - Monetize with built-in options so revenue doesn’t require extra operational work If you already have an audience anywhere online, a newsletter is how you keep it—and grow it—on your terms. beehiiv makes that transition fast. **Start using beehiiv** to turn followers into subscribers and build an audience you own. ## Related Case Studies ![How AdQuick Scaled Industry Sponsorships with beehiiv's Ad Network](https://images.prismic.io/beehiiv/Z_VpXHdAxsiBwdKG_adquick.png?auto=format,compress) ### How AdQuick Scaled Industry Sponsorships with beehiiv's Ad Network Solving scale and visibility challenges in B2B marketing [ Read Case Study → ](/case-studies/adquick) ![How Particle for Men Generated a 1.73 ROAS Through Newsletter Ads](https://images.prismic.io/beehiiv/abfLOrbci2UF6CEY_Untitleddesign-34-.png?auto=format,compress) ### How Particle for Men Generated a 1.73 ROAS Through Newsletter Ads Scaling newsletter advertising to 8.3M readers while achieving 809 conversions with beehiiv [ Read Case Study → ](/case-studies/particle-for-men) ![The Founder Who Turned His 400k+ Newsletter Into a Negative CAC Machine](https://images.prismic.io/beehiiv/afL59cBOoF08xfCT_Untitleddesign-36-.png?auto=format,compress) ### The Founder Who Turned His 400k+ Newsletter Into a Negative CAC Machine How Open Source CEO pioneered model where newsletter ad revenue offsets customer acquisition costs with beehiiv.
