As answered by people managing StackGo and BB9.
BB9's answer:
ManyChat and Chatfuel are broadcast/flow tools — great for delivering a lead magnet or triggering a keyword-based DM, but the flow is what decides what happens next, not the AI. When a lead goes off-script, asks something unexpected, or sends a wall of text answering three questions at once, the flow breaks or just fires the next scripted message anyway.
BB9 is built the other way around: reasoning is the foundation, not a layer bolted onto a flow. It handles objections, disqualifies leads who were never going to buy, and follows up on cold leads without sounding robotic — the actual sales conversation, not just message delivery. The two aren't mutually exclusive either: a common setup uses ManyChat to deliver a free resource, then hands off to BB9 once the lead is engaged to run the qualification and booking conversation.
BB9's answer:
BB9 doesn't publish a customer list, but these are businesses featured in its own published case studies/testimonials: - Roper Marketing (Jake Roper) - marketing agency - CC360 (John Nicholas) - software - wellthywoman.co (Michelle Rogers) - health/coaching - Good Men Project (Robin Reed) - author & coaching
BB9's answer:
It's not one narrow niche. BB9 fits any business getting consistent inbound DMs on Instagram (or WhatsApp/Messenger) where those conversations need real qualification before someone's time gets spent on them — coaches, consultants and course creators, but also gyms and fitness studios (trials, assessments, follow-ups), home services, restoration and insurance, vehicle and equipment sales, and other local/brick-and-mortar businesses generating leads through social media.
The common thread is volume and stakes: roughly 5-8+ DMs a day, and an offer that already converts when a human works the conversation. It's not meant for founders at low volume (handle those personally) or for validating an offer that hasn't proven out yet.
BB9's answer:
BB9 doesn't run on a decision tree like most DM tools. Every inbound message goes to a group of specialized agents — a sales agent for qualification and objections, a booking agent that only activates once a call has actually been offered and accepted, a disqualification agent that ends dead-end conversations with a resource instead of wasting a slot on the calendar, and a time agent that paces replies so they feel human instead of instant.
Voice setup is trained on the business owner's real DM conversations, not a brand guide, so the AI doesn't sound generic. And pricing is per engaged conversation (3+ messages from the lead), not per message or per seat, so a thorough 40-message qualification costs the same as a short one — the model rewards depth, not volume.
