Newsletter platforms become growth tools
Creator economy marketer and co-founder on building a sustainable business online
Non algorithmic discovery pushes newsletter platforms to become creator growth tools, not just publishing tools. If a writer cannot be surfaced by a feed ranking system, audience growth has to come from portable channels like Twitter, referrals, cross promotion, and community. That makes the product battle less about writing and payments, and more about who best helps a creator turn one reader into the next reader without trapping them in a social feed.

The interview frames the core bottleneck as audience building, not monetization. Early growth comes from a unique angle, aggregation, and word of mouth, then from moving followers over from places like Twitter or YouTube. That handoff is described as not smooth, which is why discovery matters so much.

Substack historically leaned away from algorithmic distribution, which left writers relying on recommendations, external social platforms, and community loops. Later, as competition intensified, Substack moved closer to a feed product with Notes, chat, and live video, showing how hard it is to scale discovery without adding more platform level distribution.

Beehiiv and ConvertKit attacked the problem from the tooling side. Beehiiv bundled referrals, ads, and audience growth features into newsletter software, while ConvertKit built email and creator marketing infrastructure. Their revenue scale, Beehiiv at $30M in June 2025 and ConvertKit at $43M in 2024, shows how valuable growth tooling became relative to pure publishing.
The category is heading toward hybrid products that mix ownership with distribution. The winning platforms will give creators direct subscriber control, while also adding more ways to be found, through referrals, recommendations, ads, and lightweight social surfaces. The center of gravity is shifting from newsletter software to audience compounding software.
