| Description | Sterling is an AI employee that lives in your Slack and does real ecommerce operations work — Shopify and Klaviyo audits, ad-campaign drafts, multi-channel ROAS reports, CRM updates, and QuickBooks reconciliation — by connecting to your actual store data across 3,000+ apps. It's built for ecommerce and DTC store owners and small teams who'd otherwise pay an agency or virtual assistant, and its defining trait is a human-approval gate: it drafts and prepares everything from your live data but never sends, charges, or deletes until you reply 'go' in the thread. Setup takes minutes from the Slack directory with per-tool permission controls (off, view, or full) for each teammate. | ConvertKit (now Kit) is the email marketing platform built for creators. Used by 500,000+ bloggers, podcasters, YouTubers, and course creators to grow their audience, sell digital products, and run automated email funnels. |
