What is Subbly?
Subbly's AI builder becomes interruptible, months after retention intelligence moved in-house
Development is uneven across the product. The AI Builder is where the recent motion is: model intelligence was upgraded in June, and August makes the agent steerable mid-run — a new prompt can be queued while it works and gets inserted between steps rather than waiting for the current one to finish. The subscription platform itself has been quieter since spring, when Subbly replaced a third-party churn model with an in-house one it measures as 68% more accurate, added a cancellation type setting for immediate versus end-of-period, and shipped biometric two-factor with anomaly detection.
What is Squarespace?
Squarespace adds a business account and spending card, plus SMS campaigns for the holidays.
Squarespace's November update opens Squarespace Balance to eligible US Squarespace Payments merchants: one account for payouts with same-day access to earnings, rewards on saved money and a spending card, run through Stripe and partner banks. The same update adds SMS Campaigns with consent and opt-out built in, and price and availability product filters. It follows October's customer profiles, transactional email and new Link payment methods.

Subbly's AI builder becomes interruptible, months after retention intelligence moved in-house
◆ Current state
Development is uneven across the product. The AI Builder is where the recent motion is: model intelligence was upgraded in June, and August makes the agent steerable mid-run — a new prompt can be queued while it works and gets inserted between steps rather than waiting for the current one to finish. The subscription platform itself has been quieter since spring, when Subbly replaced a third-party churn model with an in-house one it measures as 68% more accurate, added a cancellation type setting for immediate versus end-of-period, and shipped biometric two-factor with anomaly detection.
◆ Where it's heading
The builder work is converging on keeping a person in the loop while the agent runs rather than making the agent more autonomous — the stated motivation is course-correcting a run that is going wrong and avoiding wasted credits. That framing, credits as the cost of a bad run, is worth noting: it treats agent time as a metered resource the merchant is spending, which shapes what gets built next. The retention side has not seen comparable investment since the churn model landed in May.
◆ Prediction
Expect further mid-run controls on the builder along the same line — editing or cancelling a queued step, or rolling back a bad one — since the credit-waste problem this release names is only partly solved by inserting prompts.
Squarespace
6.3E-COMM
Squarespace adds a business account and spending card, plus SMS campaigns for the holidays.
◆ Current state
Squarespace's November update opens Squarespace Balance to eligible US Squarespace Payments merchants: one account for payouts with same-day access to earnings, rewards on saved money and a spending card, run through Stripe and partner banks. The same update adds SMS Campaigns with consent and opt-out built in, and price and availability product filters. It follows October's customer profiles, transactional email and new Link payment methods.
◆ Where it's heading
Each monthly update moves Squarespace further from site builder toward the merchant's whole back office: payments, invoicing, customer records, email, now SMS and the account the money sits in. The AI site generation and AI visibility work from mid-year has given way to commerce and money features ahead of the holiday season.
◆ Prediction
Expect December's update to extend Balance or SMS Campaigns, for example automations or availability beyond the first eligible US merchants; the notes give no timeline.
