GrowthStack Advisory / AI in the GTM Stack

Point of view

AI is a layer across your GTM stack, not another tool in it

Every few weeks a founder asks me which AI sales tool they should buy. The question is usually a symptom of the thing that is about to go wrong.

The short answer

AI works best as a layer across the tools your team already uses, not as a separate tool added to the stack. In practice that means using ChatGPT or Claude for account research, ICP analysis, persona work, personalisation, reply analysis, objection handling, lead prioritisation and workflow automation, improving work reps are already doing. Adding an AI tool to a stack where the ICP, messaging and qualification standard are unclear does not fix the process. It scales it.

Why the question is wrong

Behind "which AI tool should we buy" sits an assumption: that AI is a category you add. You have a CRM, a data provider, a sequencer and a dialler, so you add an AI tool and now you have five. Budget approved, tool onboarded, and three months later nothing about the pipeline has changed.

The real shift in how I work over the last year has not been a new platform. It has been using ChatGPT and Claude as a layer sitting across the tools a rep already has open, improving work they were doing anyway.

Where the layer actually touches the work

In practice it shows up in eight places, none of which are a new tab in the stack.

Every one of those already existed as a task. The layer makes them faster and more consistent. It does not replace them, and it does not add a ninth thing to buy.

Why the standalone framing fails

A standalone AI tool has to win a slot in a stack that is already full, integrate with the four things around it, and get adopted by reps who did not ask for it. Most do not clear all three. The ones that do tend to be doing something narrow and mechanical, which is fine, but it is not the shift people think they are buying.

The deeper problem is that a tool sitting beside your process cannot fix your process. It inherits it.

The part nobody wants to hear

I have been looking closely at the newer enrichment and research platforms, and the pattern that worries me is the same one AI has in general. They are very good at executing whatever you point them at. If your ICP is vague, your messaging is generic and your qualification standard was never written down, that capability does not help you. It gives you a more sophisticated way to automate a weak process, at higher volume, with better reporting on how little it produced.

Automation applied to a weak process does not fix the process. It scales it.

The order that works

Get the account list right. Get the messaging to a point where a rep can defend it on a call. Write down what qualified means and hold the team to it. Then put the layer across it and it compounds.

Do it the other way round and you will have spent a budget sending more of the same emails to a slightly better researched version of the wrong list. The sequence is the same one we use to build an outbound engine, and it starts with an ICP sales will actually use rather than with tooling.

What I am not claiming

I have not run a full client implementation of Clay, Smartlead or Cognism. I can see where each one fits and I have views on the category, but I am not going to tell you how to configure something I have not configured for a client.

My hands-on data and outbound experience is Apollo, ZoomInfo, Lusha, Sales Navigator, Instantly and Lemlist. Those comparisons are written up in Apollo vs ZoomInfo and Instantly vs Lemlist. The AI layer described above is what I am running across them today, and if that changes for the three tools above, this page will say so.

Questions

Should we buy an AI sales tool?+

Usually not as a standalone addition. A separate tool has to win a slot in a stack that is already full, integrate with the tools around it, and get adopted by reps who did not ask for it. AI produces more value as a layer across the CRM, data provider and sequencer you already run, improving account research, prioritisation and personalisation that reps are doing by hand today.

Will AI fix a low reply rate?+

Not on its own. If the ICP is vague, the messaging is generic and the qualification standard was never written down, AI produces better researched messages to the wrong list. Fix the account list, the messaging and the qualification standard first, then apply the layer across them.
