GTM Tools: The 8 We Use, Sorted by What They Do

What does GTM stand for?

GTM stands for go-to-market: everything a company does to take a product to buyers. In a sales context, “GTM tools” means the software stack behind that motion.

One clarification worth making early: GTM also stands for Google Tag Manager, a web analytics product with nothing to do with sales. If you searched for tag management, you’re in the wrong article. Google mixes both meanings in this query, which is why the results look inconsistent.

What is a GTM system?

There isn’t one product called a GTM system. There’s a chain of five jobs, and different vendors cover different links of it:

1. Find. Identify companies and people that match your ICP. 2. Enrich. Attach emails, phone numbers, firmographics and signals to those names. 3. Orchestrate. Combine sources, apply logic, decide who gets what treatment. 4. Execute. Actually reach out, across LinkedIn, email or both. 5. Follow up. Track replies, move deals forward, quote, close.

Nearly every “best GTM tools” list mixes all five into one ranking, which is why they’re hard to act on. A database and a sequencer aren’t competitors — they’re neighbours in the chain.

The practical consequence: before comparing tools, work out which link is broken for you. Most teams that feel their GTM stack isn’t working have three tools covering links 1 and 2, and nothing covering 5.

The 8 tools, by layer

1. Clay — orchestration

The tool that defined the GTM engineering category. Clay pulls from dozens of data providers in sequence, applies logic, and runs AI research on top. If your problem is “I have data in five places and no way to combine it,” this is the layer you’re missing.

Best for: technical GTM teams building custom workflows. Watch out for: it’s a builder, not a solution. Expect a real learning curve, and expect to still need something that executes the outreach.

Price: Freemium. Paid plan starts at $167 per user.

2. Apollo — database plus execution

A large contact database combined with email sequencing and CRM enrichment. The most common single answer for teams that want data and outreach in one subscription.

Best for: teams that want to cover links 1, 2 and part of 4 with one vendor. Watch out for: covering several layers means none is best in class. Its LinkedIn depth is thin compared to dedicated tools.

Price: freemium. Basic plan starts at $49 per user.

3. ZoomInfo — enterprise data and intent

The largest contact and company intelligence database, with direct dials and buying-intent signals. Built for broad ICPs and large buying committees.

Best for: enterprise teams selling across many industries. Watch out for: the most expensive option here by a wide margin, and it does not run outreach for you.

Price: Approximately at $1.250 per month for 1 to 3 users.

4. Clearbit (Acquired by HubSpot)— enrichment

Enrichment focused on filling in what you already have: turn a domain or an email into a full company and contact record. Often used to enrich inbound signups rather than to build cold lists.

Best for: teams with inbound volume that arrives incomplete.

Price: from $60 with HubSpot Plans.

5. Lusha — lightweight contact data

Simpler contact data: verified emails and phone numbers, without enterprise complexity or enterprise pricing.

Best for: small teams that need contact data occasionally, not systematically.

Price: freemium. Basic starts at $37.45 per user.

6. Phantombuster — extraction and automation

Runs automations (“phantoms”) that extract data and perform actions across LinkedIn and other platforms. Extremely flexible, and closer to a toolkit than a product.

Best for: teams comfortable assembling their own workflows. Watch out for: flexibility means you own the setup, the maintenance and the risk. There’s no opinionated default keeping you safe.

Price: freemium. Basic starts at $56 per user.

7. Pexio — execution and follow-up

Where most stacks break is after the reply. Pexio covers the last two links: it runs LinkedIn outreach in the cloud — nothing to install, no browser tab to keep open — and then keeps the conversation inside a CRM built for it.

That CRM is the part that matters here: a pipeline with lead records, tasks, a calendar, quotes, and email sending to those leads. So a prospect that came in from a LinkedIn sequence becomes a pipeline stage, a task with a date and eventually a quote, without exporting anything.

It also connects to Apollo, so teams already paying for a database can use it as the source and Pexio as the execution and follow-up layer, instead of buying a second database.

Human pacing, intraday limits and auto-pause are on by default: if a prospect replies, the next step never fires.

Best for: teams whose pipeline comes from LinkedIn and who keep losing replies in the handoff. Watch out for: it is not a contact database. If you don’t know who your buyers are, this won’t tell you.

Price: freemium. Basic starts at $19 per user.

8. Instantly — cold email at volume

Sending infrastructure for cold email: inbox rotation, warmup, deliverability management. Solves a problem that only exists once you’re sending at scale.

Best for: email-first teams sending high volume. Watch out for: deliverability infrastructure is not a substitute for having something worth saying.

Price: freemium. Basic starts at $56 per user.

What are the best AI GTM tools?

Almost every vendor in this list now advertises AI. It’s worth separating what the AI actually does:

AI that researches — reads public sources and fills in fields you’d otherwise research by hand. This is where Clay is strongest and where the time savings are real.

AI that writes — generates message copy. Useful as a first draft, dangerous as a final one. Generated outreach is the single fastest way to tank a reply rate, because prospects recognise it.

AI that decides — scores leads, prioritises accounts, picks the next action. The most valuable category and the hardest to evaluate, because the reasoning is rarely visible.

A blunt filter for demos: ask what happens when the AI is wrong. Vendors that have thought about it will have an answer. Vendors that haven’t will change the subject.

How do you build a GTM stack without overpaying?

Four rules that come from watching teams do it badly.

Start from the broken link, not from the tool. Write down where your pipeline actually stalls. Buy for that. Nearly all wasted spend in this category is a team with an execution problem buying more data.

Don’t buy two tools in the same layer. Two databases is the most common expensive mistake. Two sequencers is the second.

Check data accuracy in your niche, not the vendor’s total count. Every vendor advertises hundreds of millions of contacts. Ask for a sample of 100 in your exact ICP and check the bounce rate yourself.

Cover link 5 before you buy more of link 1. If replies are getting lost, more contacts makes the problem worse, not better.

Is LinkedIn automation part of a GTM stack?

Yes, and it comes with a caveat that most articles skip: automating LinkedIn goes against LinkedIn’s terms of service. That applies to Pexio, Phantombuster and every other tool that touches the platform. Any vendor claiming to be fully compliant is not being straight with you.

LinkedIn enforces a weekly connection cap that applies identically to everyone — no tool can raise it. What varies is risk management: pacing actions through the day, stopping when someone replies, and watching acceptance rates rather than raw volume.

A tool that lets you send more is not a better tool. It’s a faster way to lose the account.

Frequently asked questions

What’s the difference between a GTM tool and a CRM? A CRM stores and manages relationships. A GTM tool is a broader term that includes finding prospects, enriching data and reaching out. Some products, including Pexio, cover both the outreach and the CRM side.

Do I need Clay if I already have Apollo? Only if you’re combining multiple data sources or building custom logic. If one database covers your ICP, Clay is solving a problem you don’t have yet.

How many GTM tools does a small team actually need? Usually two: one for data, one for execution and follow-up. Teams under ten people rarely get their money’s worth from more.

Can I connect these tools to each other? Most offer native integrations or APIs. Pexio connects to Apollo, so you can use an existing database as the source rather than paying for a second one.

What’s the first tool a new sales team should buy? Whatever covers the link that’s broken. If you don’t know who to contact, buy data. If you know but nobody has time, buy execution.

What we learned building our own stack

Before we build Pexio, we had some trouble using chrome extension apps. Sometimes we had random log outs form our session and we had to wait like 20 - 30 minutes for the scrapping to finish and import the list to the platform. Pexio solved that problem by using a cloud solution.

We use Apollo from time to time to get some email enrichment. It works quite well for us, although we find a lot of emails that are denied for outreach and that consumes a lot of tokens without giving us a solution.

For the email enrichment that work for us we use Instantly to deliver them so that it does not get to spam. Instantly is a great tool if you want do warm up and get useful emails.

When we built Pexio we started only as a Linkedin outreach platform that helped deliver hundreads or thousands of automated actions but we then discovered the importance of the follow up to those that have been contacted on Linkedin. So the CRM was a must for us. The sales rate went from 10% to 30% of prospects already contacted, although the timing got a little bit longer because for those that did not need the service or product exactly at that time of the first approach were contacted later (with CRM) and that allowed to close the deal.

Closing

GTM tools aren’t competitors — they’re links in a chain. Sort them by the job they do, find the link that’s broken in your own motion, and buy for that one.

Most teams don’t have a tooling problem. They have three tools covering the same link and nothing covering the last one.
