What is Subbly?
Subbly is betting on an AI site builder while moving subscription retention ML in-house.
Subbly is a subscription-commerce platform whose product energy is concentrated in its AI Builder—an agentic, no-code site builder it ships to almost weekly with model upgrades, agent skills, search tooling, and credit-efficiency work. Around it, the core platform is maturing: an in-house churn-prediction model has replaced a third-party system, cancellations gained immediate-vs-end-of-period control, and account security was hardened with biometric 2FA, anomalous-login confirmation, and session review.
What is Sellfy?
Sellfy's feed is creator success stories and competitor-comparison listicles, not releases.
Sellfy is a creator-focused ecommerce platform for selling digital products, merch, and subscriptions. The crawled feed contains only blog content — founder success stories and 'best alternative to X' comparison listicles (Fourthwall, Gumroad, Gank, Shopify, Big Cartel). There are no product release notes, so shipping activity isn't observable from this source.

Subbly
2.5E-COMM
Subbly is betting on an AI site builder while moving subscription retention ML in-house.
◆ Current state
Subbly is a subscription-commerce platform whose product energy is concentrated in its AI Builder—an agentic, no-code site builder it ships to almost weekly with model upgrades, agent skills, search tooling, and credit-efficiency work. Around it, the core platform is maturing: an in-house churn-prediction model has replaced a third-party system, cancellations gained immediate-vs-end-of-period control, and account security was hardened with biometric 2FA, anomalous-login confirmation, and session review.
◆ Where it's heading
Two parallel bets. First, make the AI Builder cheaper and more capable per credit—token-efficient models, a code-search tool, on-demand skills—so it becomes the default way merchants build storefronts; it remains waitlist-gated, suggesting a controlled rollout. Second, deepen retention and operations features specific to subscription businesses, with the in-house churn engine the clearest example of owning rather than renting a core capability.
◆ Prediction
Expect more AI Builder skills and model options with continued credit-cost reductions, and the in-house churn model to feed more automated retention actions such as win-back automations.
Sellfy
5.0E-COMM
Sellfy's feed is creator success stories and competitor-comparison listicles, not releases.
◆ Current state
Sellfy is a creator-focused ecommerce platform for selling digital products, merch, and subscriptions. The crawled feed contains only blog content — founder success stories and 'best alternative to X' comparison listicles (Fourthwall, Gumroad, Gank, Shopify, Big Cartel). There are no product release notes, so shipping activity isn't observable from this source.
◆ Where it's heading
The content strategy is built on capturing creators dissatisfied with competitors — alternative and comparison posts targeting Gumroad, Fourthwall, Shopify, and others — paired with aspirational creator case studies. This signals a customer-acquisition motion aimed at creators outgrowing simpler tools, not a product-roadmap narrative.
◆ Prediction
Expect continued comparison and creator-story content rather than feature announcements; the product's actual development isn't visible in this feed.
