Conversational AI for multi-brand marketplaces.
heysteff is an AI platform for customer support and sales across WhatsApp, Instagram, Messenger, Gmail and Shopify; Steff is the AI agent that runs it. A marketplace doesn't serve one catalog — it serves several, each with its own tone, its own team, and sometimes its own country. heysteff is built multi-tenant from the ground up, so every brand lives isolated inside the same platform, without mixing with the rest.
True multi-tenant: every brand, every store, every country
Each brand operates in its own workspace, with its own trained agent, its own connected channels and its own users — not a label over one shared inbox. If you manage several brands or several countries, the Max plan is built exactly for that: unlimited channels, 20 users, 3 Shopify stores and everything else (scheduling, custom tools, campaigns) uncapped. Each brand can even choose its own AI model (Anthropic, OpenAI, DeepSeek or OpenRouter) if it needs to.
Conversation assignment per team or vendor
Inside each workspace you can assign conversations to the right person or team, so every vendor sees only their own and nothing gets lost between inboxes. Roles and permissions define who can reply, who can pause the bot, and who can only view, and every action — assignment, pause, status change — is recorded in the audit log.
Per-brand channel consolidation, in separate inboxes
Each brand's WhatsApp, Instagram, Messenger and Gmail consolidate into its own unified inbox, inside its own workspace. An operator working across several brands can move between them without one brand's information leaking into another — the separation is real, not just visual. Each brand can also have its own WhatsApp number (official or a number you already have) and its own channel setup, so the catalog, automated replies and flows of one store never cross with another's inside the same marketplace.
Roles and permissions with an audit log
You define what each role can do inside each workspace: who administers the agent's configuration, who only handles conversations, who only sees reports. Every relevant change — from pausing the bot to editing a flow — lands in the audit log, so you can always reconstruct who did what and when across every brand you operate.
How it connects
Each brand connects its own channels (WhatsApp, Instagram, Messenger, Gmail) and its own Shopify store independently inside its workspace. A multi-brand deployment on the Max plan is estimated at 2-3 weeks with dedicated onboarding, brand by brand — each with its own AI provider, calendar and custom tools if it needs them, without waiting on the rest of the marketplace to go live.
◆ frequently asked questions
Can I have one brand per workspace, with its own agent and catalog?
Yes. heysteff is genuinely multi-tenant: each workspace is an independent brand, with its own trained agent, its own catalog, its own channels and its own users, isolated from the others.
How do I split conversations across my team or vendors?
You can assign conversations to specific people or teams inside the workspace, and use roles and permissions to control who sees and replies to what. Every action is recorded in the audit log.
How many Shopify stores can I connect?
It depends on the plan: Pro includes 1 Shopify store with cart recovery, and Max, built for multi-brand operations, includes 3 Shopify stores and unlimited channels. The Starter plan does not include a Shopify store.
