SureThing is an AI agent platform that positions itself as a general AI agency: a shared team of agents covering operations, marketing, research and engineering that connect to your existing apps, execute multi-step work in the background and hand back finished deliverables rather than chat replies.
Start from a ready workflow — social automation, product photos to posts, website audits, competitor monitoring — instead of an empty chat box.
All agents draw on the same memory, so voice, brand context and past decisions carry across marketing, research, operations and engineering tasks.
Connects to 1,000+ tools including Slack, Gmail, Notion, Linear, GitHub, Stripe, Shopify, HubSpot, Google Ads and Figma, with an API path for anything missing.
Agents prepare deliverables and pause for sign-off before anything irreversible, such as publishing content or changing ad spend.
