With 20+ years in marketing and prior experience in corporate newsletters, he aimed to build a newsletter-first business model that combined rapid growth with sustainable monetization. ### **Challenge:** Sobko needed a platform that allowed him to experiment fast, scale subscriber growth aggressively, and monetize early. He also wanted to turn reader interest into real revenue without the complexity of managing multiple tools or a large team. ### **Solution:** Using beehiiv’s all-in-one suite, Sobko experimented weekly, optimized based on subscriber feedback, and grew his audience from 4,000 to 50,000+ through a mix of paid media, beehiiv Boosts, and the beehiiv Ad Network. He added premium subscriptions, private ad deals, and even launched a second newsletter (_Grow Monetize_) plus a beehiiv-focused newsletter agency—all built within the beehiiv ecosystem. ### **Results:** - Reached **$16,600/month in revenue** and **$65,000 in 7 months** - Grew to **50,000+ subscribers**, adding **12,000/month** - Monetized via beehiiv’s Ad Network, Boosts, premium subs, and direct sponsors - Launched a second newsletter and a profitable agency helping others grow with beehiiv Sobko calls beehiiv “the best platform for newsletter operators,” and adds, “With beehiiv, you can literally make your first dollar in week one.” His goal: hit $500K/year and launch a dozen newsletters by next year. ## 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.
