A deal with one contact isn't a pipeline entry, it's a coin flip. If that person changes roles, loses interest, or simply gets busy, the deal doesn't stall, it disappears, and you usually don't find out for weeks because nobody else on your side knows the deal exists.
Founders running their own outbound tend to build a relationship with the first person who replied and stop there. It feels efficient; you're not managing five threads, just one. But that one person has to survive an internal budget review, keep advocating for a vendor they haven't bought yet, and still be at the company by the time a contract is signed. Roughly a third of the B2B champions a founder starts a deal with will change roles or lose bandwidth before that deal closes. When that happens with no second contact in place, the deal doesn't move to a new stage. It goes quiet, and it usually stays quiet, because your only record of the relationship lives in one person's inbox, not yours.
You rarely get a clean signal that a deal is dying. What you get instead is a pattern, and the pattern is recognizable if you know what to look for. Response time stretches from same-day to three-plus days. Replies get shorter and vaguer, moving from specific next steps to "let me check and get back to you." And the champion stops using "we" in favor of "I," which usually means they've stopped speaking for the buying committee and started speaking only for themselves. Any one of these alone isn't a crisis. All three together, and you're single-threaded on a deal that's already slipping without your knowledge.
Most advice says to multi-thread once a deal is 'serious,' which in practice means after a demo has already happened and the single champion has already invested weeks of internal politics on your behalf. That's too late to look natural. Instead, plan for a second contact by the fourth touch in your sequence, whether or not the demo has happened yet. If your champion hasn't looped in anyone else by then, ask directly who else would be affected by this decision and request an introduction, or reach that person independently with a short note that references the existing conversation.
This isn't about going around your champion. It's about making sure the deal survives if your champion can't carry it alone, which happens more often than founders expect during the exact stretch we cover in Founder-Led Outbound: What to Do in Your First 90 Days .
Founders avoid bringing in a second contact because it feels like an accusation that the first one isn't enough. It isn't. Frame it as scheduling logistics: "want to make sure this doesn't stall if you're out, mind looping in whoever else would weigh in on this." Said plainly, almost no champion objects. Said apologetically, or not said at all, the deal stays fragile on a single point of failure.
There's a second, quieter version of this failure mode: founders who do ask, get a yes, and then never follow through because the deal feels busy enough already. Asking for a second contact and not actually reaching them within a week is functionally the same as never asking. Put a date on it. If you don't have a name and an email for a second stakeholder within seven days of asking, treat that as a stalled deal and escalate the ask again, more specifically this time, naming a likely role rather than leaving it open-ended.
Once you're running two or three parallel threads per deal, the coordination problem becomes real: who said what, to whom, and when. Without a shared system, you end up sending contact B the same pitch you already sent contact A three weeks earlier, or worse, contradicting a promise your champion already made. We keep every stakeholder thread tagged to the same deal inside a shared inbox in Agent360, so when a second contact replies at 4pm, whoever's watching the inbox sees the full history instead of starting cold. That matters most in the first hour after any reply, which is the window we break down in 5 Ways AI Chatbots Cut First Response Time .
By the fourth touch in your outbound sequence, regardless of whether a demo has happened. Waiting until the deal feels 'serious' is usually too late to introduce a second contact without it seeming unusual.
Rarely, if you frame it as continuity planning rather than doubt in them. Ask who else would weigh in on the decision so the deal doesn't stall if they're unavailable.
Tag every thread to the same deal in a shared inbox so anyone responding sees the full history, not just the most recent message from one contact.
