Most sales teams that pay for Gong use it as a very expensive tape recorder. Calls go in, someone replays one when a deal goes sideways, and the rest sits there. Gong’s September release, Mission Callisto, added contact enrichment and a slower “think harder” mode to its assistant. I’m not going to walk you through the feature list. What matters is that those two things, together with the calls you’ve already recorded, are enough to run three plays that bring in money you’re currently leaving on the table. Here’s how I’d run each one, and which one I’d start with.

Play 1: Get stalled quotes moving again

The money: quotes that are already out and have gone quiet. You’ve done the hard work on these: discovery, the site visit, the pricing. They’re the cheapest revenue you’ll ever win back.

How I’d run it:

1. Pull every open deal at quote stage with no customer reply in 14 days or more. Sort by value.
2. For the top ten, ask Gong Assistant in Deep Mode something specific: “Across the calls and emails on this deal, what objection or open question was never resolved, and who raised it?” Don’t ask “why is this stalled?” A vague question gets you a vague answer.
3. Read the evidence it cites. If the calls really say what it claims, your follow-up writes itself: “On our last call, Sam asked about lead time on the spare parts, and I never came back with a firm answer. Here it is.” That’s a much better reason to get back in touch than “just checking in.”
4. Track it. Mark these ten deals and see how many move in 30 days compared with the rest of the stalled pile.

The maths, as an example: ten stalled quotes averaging $40k is $400k sitting still. If a specific, evidence-based follow-up wins back two that would otherwise have died, that’s $80k from an afternoon’s work. Use your own numbers, but you’ll usually find the pile is bigger than anyone thought.

Play 2: Add more contacts to your biggest deals before they go missing

The money: your largest deals depend on one contact. When that person goes on leave, changes role or loses the internal argument, the deal dies and nobody else at the customer knows who you are.

How I’d run it:

1. List your ten largest open deals. For each one, check who has actually turned up on calls: the engineer who joined the second meeting, the finance person who asked about payment terms.
2. Anyone who was on a call but has no contact record gets filled in with Gong Enrich. It checks providers like ZoomInfo, Apollo and Lusha one after another until it finds a verified email or number.
3. Give each of those people a reason to hear from you that’s about their job, not the deal. Send the engineer the technical spec they asked about, and send finance the payment schedule.
4. Any big deal that still has only one contact after this is a forecast risk. Say so in the pipeline review instead of finding out at month end.

This is the play with the slowest payback, but it’s the one that stops big deals collapsing. It also needs very little skill, which is why I like it.

Play 3: Find upsell conversations in your existing customers’ calls

The money: customers who have already told your account managers what else they need, on a recorded call, and nobody acted on it.

How I’d run it: once a month, ask Deep Mode: “In calls with existing customers over the last 90 days, where did a customer mention a new site, a new line, a capacity problem, or a competitor’s product they’re also using?” Each result is a warm lead with a quote attached. Hand them to whoever owns the account with the call snippet included, so they can open with “you mentioned…” instead of a cold pitch.

How I’d actually do it

Start with Play 1. It’s the fastest money, it uses only features that are live today, and it proves within a month whether Gong’s AI is worth what you pay for it. If the Deep Mode answers don’t match what’s actually in the calls, you’ve learned something cheap. Play 2 comes next, because it protects revenue you’re already counting on. Leave Play 3 until the first two are habits.

Here’s what I wouldn’t do. Ignore the headline feature for now. Gong’s Agent Builder lets you set up agents that act on their own when a deal goes quiet or a competitor gets mentioned. It’s the part everyone is writing about, and it’s “rolling out throughout 2026,” which for most customers means not yet. Even when it arrives, an agent that chases quiet deals is only as good as your deal data. If stage dates are wrong and half the pipeline belongs to someone who left in March, it will chase the wrong person about the wrong deal, every time. Do Play 1 by hand first. The list of events you build doing it is the spec for the agent later.

And the honest caveat: if you don’t already have Gong, none of this is a reason to buy it. A small technical business with three salespeople can run Play 1 with a spreadsheet and the call notes they already have. Gong makes it faster. It doesn’t make it possible.

Where this fits

Play 1 is the same idea as drafting CRM follow-ups with AI, aimed at the deals worth the most. If you’re on Pipedrive instead, Nova gets you most of the way. And if Play 2 turns up a pipeline where nobody can say which deals are real, that’s the actual work of CRM Pipeline Rescue: fixing stages and ownership so the money becomes visible before any AI is asked to chase it.

What shipped, for reference: Gong Enrich (third-party contact data from 10+ providers) and Deep Mode in Gong Assistant are generally available. Agent Builder (event-triggered Custom Agents) and expanded dashboards are rolling out through 2026. No pricing announced.
