“I’ll follow up on that” is the most expensive sentence in sales

Every rep has said it. Every manager has heard it. It sounds harmless, even responsible. You’re not dodging the question, you’re just going to handle it later.

But later is where deals go to die.

Our co-founder and CEO, Adam Liska, said it best on a recent episode of GTMnow: that one sentence is the single most expensive promise a rep can make. Here’s why, and what we’re doing about it.

The promise nobody tracks

Think about what actually happens after a call ends. The rep has five more conversations lined up. The follow-up gets added to a list, and that list loses, every time, to the inbox and the rest of the day’s admin. Three days later, the urgency the prospect felt on the call is gone, and nobody decided that on purpose. It just slipped.

Here’s the part that makes it expensive rather than just annoying: the CRM doesn’t know any of this happened. The deal still shows as live and active, because as far as the system is concerned, nothing changed. The manager builds a forecast off that same data, mostly guessing, because they know the CRM is a lagging indicator at best. The CRO takes that forecast into a board meeting, misses plan, and has to explain a miss that was actually baked in weeks earlier by a promise nobody followed through on.

That’s the execution gap. You can have all the data in the world and still lose, because knowing what to do and actually doing it are two very different muscles.

Why this isn’t a “just be more disciplined” problem

It’s tempting to file this under rep accountability. Adam doesn’t see it that way, and neither do we. The best reps have always been great at the part of the job that can’t be automated: reading a champion’s hesitation on a call, knowing when to push and when to hold back, building the kind of trust that gets a deal unstuck. That instinct was never the problem.

The admin around it was. Account research before a call, CRM updates after it, drafting the follow-up email, prepping the handover to CS, building the business case doc. None of that requires the rep’s judgment, and all of it competes for the same 20 minutes between calls that the follow-up promise also needs.

So the promise loses. Not because the rep doesn’t care, but because the system was never built to hold them to it.

What actually changes when execution is the product

This is the whole thesis behind the rebrand, honestly. We started as Glyphic, built around the idea of generative intelligence and language. Good story, but it didn’t match what customers actually needed from us, which was speed and follow-through on the data they already had. Airspeed is a much more honest name for what we do.

In practice, that means the platform doesn’t just tell a rep what happened on a call, it turns that into a corrective action. If a similar deal stalled in the past because nobody looped in the CFO, and this deal is showing the same pattern, that gets surfaced before it becomes a repeat of the same mistake, not after. That’s coaching that happens in the flow of the deal instead of in a quarterly one on one, three months too late to matter.

And the goal was never to replace the rep. Adam’s pretty direct about this: the role of the sales rep is getting stronger, not smaller. The same thing happened in software engineering. AI took the busywork off the plate, but nobody’s cutting the engineering team, because the judgment and craft still matter, arguably more now that everything else moves faster.

Sales is heading the same direction. Take the admin off the rep’s plate, and what’s left is the actual job: selling.

The takeaway

“I’ll follow up on that” isn’t a bad sentence because reps are lazy. It’s a bad sentence because nothing in most GTM stacks is built to catch it when it slips. Close that gap, and the forecast stops being a guess, the CRO stops getting surprised in board meetings, and reps get to spend their time on the part of the job that actually needs a human.

That’s the execution gap. That’s what we’re closing.
