ConvertKit as Creator ERP

The durable opportunity here is not a new consumer internet category, it is software that turns audience into a small business. The big platforms still win by aggregating attention and paying a small elite, while ConvertKit and Beehiiv sell creators and adjacent SMBs the boring but valuable tools to capture emails, automate follow ups, sell products, place sponsorships, and buy or trade for new subscribers across owned channels.

• ConvertKit looks more like vertical email SaaS than a hit driven media platform. It carved creators out of the broader ESP market, reached $38M ARR in 2023 and about $43.2M by the end of 2024, and expanded by layering sponsorships, commerce, recommendations, and 180 plus integrations on top of email.

• The split in the market is business model first. Substack monetizes by taking 10% of reader spend and is pushing toward a social feed and ad product to keep top writers. Beehiiv and ConvertKit monetize more like software, then add ad networks and subscriber marketplaces as extra revenue and retention layers.

• What gets called creator economy is increasingly just the software stack for business of 1 and small media brands. Earlier research on Beacons showed the same pattern, creators use social platforms for discovery, then move fans into owned storefronts, newsletters, products, tips, courses, and sponsorships where they control the customer relationship and economics.

From here, the winners are likely to look less like celebrity platforms and more like creator ERP. The next leg is deeper bundling of growth, monetization, and back office workflows, so creators, newsletters, coaches, and niche SMBs can run an audience business from one system while staying portable across channels.
