What do you like best about the product?
As an Account Manager, I like having account intelligence, contact data and buying signals in one place. When I'm planning a cross-sell from a single module, like Events or Audits, to the full EHS platform, I can quickly see who else sits in a customer's Health & Safety, Operations and Facilities teams. Job change alerts and company news help me time my outreach, so conversations feel relevant rather than random.
What do you dislike about the product?
Data coverage can be patchy for UK-based contacts and mid-sized companies, especially direct dials and mobile numbers for site-level or operational roles, which are often the people I need for EHS conversations. Some contact details are outdated, so I still verify information before reaching out. The platform also has a learning curve, and it took time to set up useful filters, alerts and saved searches for our existing customer base.
What problems is the product solving and how is that benefiting you?
My main challenge is expanding within existing accounts, moving customers using one module towards the wider platform with Sites, Assets and Contacts. GTM Workspace helps me map the buying committee beyond my day-to-day contact, find new stakeholders and spot triggers like leadership changes, acquisitions or site expansions. This means I spend less time on manual research, go into renewal and expansion conversations better prepared, and build a stronger pipeline of upsell opportunities.

Helpful for prospect research and organizing contact data, but still needs verification
Reviewed on Sep 29, 2026
Review provided by G2
What do you like best about the product?
I liked having company and contact information available in one place rather than searching across multiple sources. The AI was a helpful starting point for prospect research because it quickly organized available information and highlighted useful details, which made the research process easier and saved me time. The intent and website visitor signals were also useful for narrowing down potential opportunities and giving a better starting point for outreach, especially when combined with additional research.
What do you dislike about the product?
A few records needed additional verification, and I still had to verify some of the information before relying on it. The intent and website visitor signals work best when combined with additional research rather than relying on them alone. Even with workflows and AI, some tasks still required manual review.
What problems is the product solving and how is that benefiting you?
It saved me time by reducing repetitive manual work, especially when researching companies and organizing prospect information. Overall it streamlined day-to-day work, made it more convenient and efficient, and helped narrow down a list of potential opportunities for outreach.

Strong for lead building and enrichment, but filtering and CRM alignment take work
Reviewed on Sep 29, 2026
Review provided by G2
What do you like best about the product?
I really value Lead Builder and the data cleaning/enrichment because they make it much easier to find the right contacts and keep account data accurate without having to do everything manually. Lead Builder helps me quickly identify relevant people within target accounts, and enrichment fills in missing information so I get a more complete picture. The data has also been dependable overall, especially for company information, job titles, and contact details at larger organisations.
What do you dislike about the product?
Filtering and segmentation can take some trial and error, especially with a lot of criteria, and it can be difficult to get the exact segment I want without refining filters several times. CRM integration is useful, but keeping data consistently aligned between systems can require manual checking and maintenance. AI is less effective for very specific or nuanced queries because the answers can be too generic or miss context, and some contact details (like job titles or recent role changes) still need correcting. I also don’t use industry research/news/alerts as regularly because the volume of information can be hard to filter down to what’s genuinely relevant, and alerts would be more valuable if they were easier to customise and prioritise.
What problems is the product solving and how is that benefiting you?
The biggest benefit has been time saved on research and data admin, so I can spend more time engaging with customers and prospects. Automating account and contact research, enrichment, and list building reduced manual searching across different sources and made the overall research process much more efficient, even though I still need to review and validate information. Intent and website-visitor signals helped as an additional indicator to prioritise accounts for further research when they aligned with other info I already had.

Seamless integration, but data accuracy and search errors can be frustrating
Reviewed on Sep 29, 2026
Review provided by G2
What do you like best about the product?
The seamless integration is indispensable because without it we cannot work in disjointed workflows. The AI also really helped craft a proper workflow from scratch within our environment.
What do you dislike about the product?
It’s not always accurate and up to date information, which is quite frustrating, and there are also some errors that show up in the search. Overall the data felt mixed, like a 60-40 split with some outdated data still there.
What problems is the product solving and how is that benefiting you?
It helped me craft a proper workflow from scratch within our environment, and the seamless integration helps us avoid disjointed workflows.

Contact and company info in one place, but I still have to verify details

What do you like best about the product?
I like having contact and company information available in one place. It saves time during prospect research and makes it easier to find the right accounts and contacts without jumping between the tools. I generally prefer using the available search and filtering tools directly.
What do you dislike about the product?
The information can sometimes feel incomplete or inconsistent, especially when researching specific industries or technology usage. I occasionally need to cross-check the data with other sources before using it for prospecting.

Reliable contact data and workflows that cut manual research and data entry
Reviewed on Sep 28, 2026
Review provided by G2
What do you like best about the product?
For my day-to-day GTM work, having reliable company, technographic, and contact data all in one place makes prospecting and account research much easier. I can quickly understand a company’s size, technology stack, and the right people to reach out to without validating info across multiple sources. The contact information, especially direct dials and verified email addresses, has been extremely reliable for our sales outreach, and we rarely run into bounced emails or dead numbers when targeting executive profiles. The automated workflows and AI also streamline lead routing and contact enrichment, so we no longer have to hunt down accurate emails or phone numbers.
What do you dislike about the product?
My biggest frustration is that the contact and technographic data can sometimes be outdated or incomplete. I end up spending extra time verifying details, cleaning up records, and filling in missing information before I can actually use the data. Crafting truly personalized outreach emails and navigating more complex account negotiations still require a fair amount of manual effort, and building genuine relationships and closing deals still need our team’s human touch.
What problems is the product solving and how is that benefiting you?
It cut down our manual research by instantly identifying target accounts and automatically populating our CRM records with verified contact data, and it automated lead routing based on our ideal customer profile. The workflows have saved our team hours of manual data entry and made the early stages of our process much smoother. Accurate contact details improve the quality of my outreach and reduce wasted effort caused by outdated or incorrect data, and the firmographics (like revenue and employee count) save us hours of manual research.

AI turned it from list extraction into targeted outreach with real prospects
Reviewed on Sep 28, 2026
Review provided by G2
What do you like best about the product?
The AI features added over the years have taken the tool from a list extraction to a direct email campaign program with the right people who have worked with us before or are ideal to future outreach. It’s not a name and email anymore, but truly a prospect. The data has been very dependable, especially the information from our past contacts pulled from previous reps’ notes, and Zoom tracking new people in similar roles. I also like seeing who found us via engagement and getting the reports during the week to stay top of mind.
What do you dislike about the product?
I haven’t used the direct email functionality much, mainly because I prefer to keep everything in my regular email tools. It’s not that it doesn’t work; I just need a single repository for my email.
What problems is the product solving and how is that benefiting you?
It helped us keep the conversation going and build trust by tracking new people in similar roles. Seeing who found us via engagement lets the conversation begin or resume. It reduced manual work by moving historical and project interaction into daily outreach with a message that is just for the prospect, and I’ve used the AI tool to write messages and build account plans.

Helpful for finding the right people and context, but contacts can be outdated
Reviewed on Sep 27, 2026
Review provided by G2
What do you like best about the product?
I use it to make sure I’m finding the right people, with the correct data and the right context. Contact and company data availability and the CRM/marketing automation integration work well for what I need.
What do you dislike about the product?
Contacts aren’t always up to date, and it doesn’t work well for international data. I also don’t use some features because the Technographic Intelligence data feels outdated, subsidiaries get misclassified, and the email marketing isn’t good for the masses.
What problems is the product solving and how is that benefiting you?
It helps me find the right people and gives me the right context with the data I need.
