What is Rebuy?
Rebuy's feed is event recaps and ecommerce trend essays, not release notes.
The recent feed is conference recaps from the Momentum Innovation Summit in London and NYC, a BFCM infographic, and trend essays on headless commerce and AI personalization. Rebuy is a Shopify personalization and merchandising engine, but this channel carries brand and event content rather than product changes.
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.

Rebuy
0.0E-COMM
Rebuy's feed is event recaps and ecommerce trend essays, not release notes.
◆ Current state
The recent feed is conference recaps from the Momentum Innovation Summit in London and NYC, a BFCM infographic, and trend essays on headless commerce and AI personalization. Rebuy is a Shopify personalization and merchandising engine, but this channel carries brand and event content rather than product changes.
◆ Where it's heading
Rebuy is investing in community and thought leadership around AI merchandising and retention, the themes its events emphasize. Product direction is implied, AI-driven personalization, but not shipped in this feed.
◆ Prediction
Expect more event-driven and trend content tied to the ecommerce calendar; a dedicated release channel will be needed for actual feature news.
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.
