B2B Contact Databases Software

At present, Apollo.io is not a tool you should invest in if you don't have it already. The current goal seems to be to extract maximum revenue from customers. This meant taking parts of the existing functionality and charging it as an 'add on.' Most of the development is behind a paywall with extra charges, and in many cases, small businesses cannot benefit without buying multiple licenses. Apollo.io should review its approach for small businesses, especially those not based in the US. Currently, to use the dialing feature in the UK, you need to buy the next tier, but this is not available unless you purchase multiple licenses. So essentially, core functionality is not available to any SME outside of the US. Review collected by and hosted on G2.com.

Apollo.io initially solved problems by integrating multiple outreach tools, offering sales outreach and prospecting at a great price for startups. Review collected by and hosted on G2.com.

At times, some contact information may need validation, especially in less active markets, which requires occasional manual double-checking. However, even in those cases, the volume and ease of access to data still make the platform highly efficient and worth using daily. Review collected by and hosted on G2.com.

Seamless.AI is solving one of the biggest challenges in sales and business development: finding accurate, qualified contacts quickly and consistently. Instead of spending hours searching for decision-makers or validating outdated information, I can generate reliable lead lists in minutes. It also helps organize and enrich our existing database, ensuring that our team is always working with clean, actionable data.

The main benefit for me is efficiency — I’m able to focus more on strategic outreach and closing opportunities rather than doing manual research. This has directly improved our prospecting flow, increased the volume of qualified leads, and helped us accelerate new business opportunities for the company. Review collected by and hosted on G2.com.

One drawback is that it’s easy to feel overwhelmed by the amount of information available. However, refining your searches can help manage this. Review collected by and hosted on G2.com.

Zoominfo has made it much easier for us to reach those hard-to-find contacts at prospective companies. Since we offer highly technical products, it can often be challenging to locate the right people within facilities through online searches alone. With Zoominfo, we are able to identify the contacts we need, and we also benefit from additional insights such as intent data, responsiveness, and other key information about the company. The platform integrates smoothly with Hubspot, ensuring that data is efficiently shared across our resources. Review collected by and hosted on G2.com.

I dislike their dishonest and misleading advertising. They promised 50 free leads with no conditions, then changed the offer to 2 months free, and finally reduced it to only a 3-day trial once I signed up. It feels deceptive and untrustworthy. They waste your time and collect your information under false pretenses. Review collected by and hosted on G2.com.

A-Leads didn’t solve any problems for me. Their platform claimed to provide qualified leads and help grow my business, but I never got the chance to test it properly because their free offer was misleading. Instead of delivering value, they created confusion and wasted my time with changing trial terms. Review collected by and hosted on G2.com.

I found several issues with Instantly that detracted from my experience. The platform was consistently lagging, which hindered my workflow and made it difficult to manage tasks efficiently. Additionally, the customer support was not helpful; despite multiple attempts to resolve issues, I received little clarity or assistance. The unclear pricing structure was another problem, making it challenging to understand the costs and features associated with different plans. I also faced significant difficulties with lead management; the system did not allow me to work effectively with the collected data, and there was a lack of guidance on utilizing it properly. Furthermore, while I tried to integrate Instantly with other tools, it only managed to work with Slack, which limited its usefulness in a more integrated tech stack. Review collected by and hosted on G2.com.

I find Instantly reaches a large number of potential leads but poses challenges like lagging performance, unhelpful support, unclear pricing, and ineffective lead management. Review collected by and hosted on G2.com.

Occasionally, some of the contact data can be outdated or missing for niche industries or smaller regions, but this is quite rare. The Cognism team is proactive about improving coverage and regularly updates their database, which helps mitigate this over time. Review collected by and hosted on G2.com.

Cognism helps us solve the challenge of finding accurate, compliant contact data for our outbound sales efforts. Before using it, our SDRs spent hours manually sourcing leads with inconsistent results. Now, we have a reliable database of verified contacts and intent data, which saves time, increases response rates, and ensures GDPR compliance. As a result, our pipeline quality has improved significantly, and we’ve seen faster deal cycles. Review collected by and hosted on G2.com.

One downside I've identified from my use of DemandBase at a previous company is the alert features don't show intent score changes by account. You can set an alert for a specific segment to show the top 25 'hot' accounts, but with DemandBase you were able to set an alert that would show all changes by account whether a decrease in intent score or an increase - it was helpful for reps that had a specific streamlined focus on a subset of accounts to see if they were becoming less interested in a topic for example. Would love to see that feature expanded at 6sense or even just a better alert set up. Right now its very easy to use, which is great, but it would helpful to have more customization on the alerts, types of alerts and metrics of success to include within the alert. Review collected by and hosted on G2.com.

One key feature that I love and use everyday is the dynamic workflow, pushing a segment into different advertising campaigns on LinkedIn depending on the accounts buying stage, intent keyword research and profile fit. It helps us to deliver the right content at the right time to the right accounts and because its dynamically set to update every 24 hours it means its constantly looking for accounts that fit the criteria to serve them new ads or content. Review collected by and hosted on G2.com.

If I had to pick anything, it is that the platform can feel a bit complex at first and takes time to get fully confident with all the features. There is a lot of capability, which is great, but it does mean the learning curve is slightly steeper than expected.

To get the most out of it, you really benefit from having dedicated support or training alongside you. The tool is powerful, but it is not always plug-and-play, and having someone guide you through setup, best practices, and how to interpret the insights makes a big difference.

Lead Forensics is solving the problem of anonymous website traffic - turning visits into identifiable companies and decision makers we can actually act on. Instead of seeing only numbers in analytics, we can understand who is engaging with our content, what they are looking at, and how interested they are.

That benefits us by helping to uncover opportunities we would otherwise miss, prioritise follow-up based on real intent, and tailor our marketing and outreach to what prospects are genuinely exploring. It supports more timely, relevant conversations and helps us focus effort on organisations that are already showing signals of interest in our services. Review collected by and hosted on G2.com.

Pricing of BookYourData premium is bit high. However may be the features and quality of data they offered the pricing is justified. Review collected by and hosted on G2.com.

Before using BooYourData we use to collect leads using cold calling only now using this platform we have precise info of the prospects. Review collected by and hosted on G2.com.

The only thing I wish was different is that there isn't a dedicated app yet for replying to emails on my phone. It would be a lot more convenient to manage replies on the go instead of just through the web interface or with workarounds like webhooks. Review collected by and hosted on G2.com.

Getting me in front of people that are in need of my services, with the right message at the right time. Review collected by and hosted on G2.com.

I am saying this from the standpoint of honesty and unbiased as possible. There is nothing I dislike like about it. Review collected by and hosted on G2.com.

As someone who lives in outbound, my biggest bottleneck has always been data quality. Wiza solves that by giving me consistently accurate contact information, which directly increases my connect rates and saves hours every week. It lets me focus on meaningful outreach instead of hunting down the right details, and that’s been a huge lift in overall productivity. Review collected by and hosted on G2.com.

While the platform works really well overall, sometimes the customization options feel limited. I would also like to see more integrations with third-party apps. Additionally, the learning curve at the beginning requires some time, but once you get used to it, the workflow becomes smooth. Review collected by and hosted on G2.com.

Success.ai is helping me save a lot of time in outreach and follow-ups. Earlier, writing and personalizing emails for prospects used to take hours, but now with its AI features I can do it in minutes. It has also improved my response rate and given me clear analytics about what is working and what is not. This has helped me stay more consistent, reduce manual effort, and focus on strategy instead of repetitive tasks Review collected by and hosted on G2.com.

With such vast pool of contacts, it's easy to overbuild list if the filters aren't used carefully. A bit more guided list- building support or a smart suggestion system would make the experience even more powerful. Review collected by and hosted on G2.com.

In the fast moving world of data and Ai, timing and precision are everything. Global Database allows our team to confidently approach high value partner and clients with a dep understanding of their structure and leadership before we even start the conversation.

Just wish I had it earlier! I will say that because Collective[i] can feel “too good to be true,” it takes our sellers some time to fully trust the AI. But once they see the accuracy of the insights and how much time it saves them, it’s all systems go. The initial skepticism quickly turns into full adoption once they realize how much more productive they can be. Review collected by and hosted on G2.com.

Before Collective[i], our sales team struggled with inconsistent data, inaccurate forecasting, and inefficiencies in sales execution. Now, we have:

- Real-time, AI-driven pipeline insights that proactively highlight risks and opportunities.

- No more manual CRM updates, freeing our sellers to focus on selling.

- Better forecasting accuracy, leading to smarter decision-making.

- AI-driven deal coaching, improving win rates and seller productivity.

Overall, Collective[i] has been a game-changer for our revenue organization. If you're serious about leveraging AI to drive sales performance, eliminate manual work, and improve forecasting accuracy, Collective[i] is a must-have. Review collected by and hosted on G2.com.

Occasionally, I encounter some bugs, which are inevitable when a product is growing so quickly. However, the support team is very responsive and resolves issues fast. Also, additional tools, such as email warm-up, would be a great addition to make the platform even more effective. Review collected by and hosted on G2.com.

GetSales.io helps automate and scale outbound lead generation, making it easier to reach potential clients through LinkedIn and email. It saves a huge amount of time by handling outreach sequences, follow-ups, and personalization at scale. Thanks to this, we can generate more leads, increase response rates, and focus on closing deals rather than manual outreach. The analytics and tracking features also help optimize campaigns for better results. Review collected by and hosted on G2.com.

I use Mr. E by EasyLeadz to find accurate contacts and obtain an unlimited number of emails from LinkedIn, making lead generation highly effective. Review collected by and hosted on G2.com.

Overall, I liked the tool, but I wish the email finder feature gave better and consistent results for smaller domains as well. I occasionally got unknown statuses, so I had to double check manually. Review collected by and hosted on G2.com.

My newsletters had a very high bounce rate before using Clearout. It helped me in cleaning up the large email lists that brought a significant drop in bounces and improved the overall inbox placement. I've also used the tool for lead verification I captured via landing pages in real time. Review collected by and hosted on G2.com.

So far, I haven't found anything I don't like about Keyplay - we just signed on for another year and I can't imagine 2026 planning season without it! Review collected by and hosted on G2.com.

Keyplay helps us score our prospect accounts so we can focus our sales teams on the ones most likely to convert. Instead of spreading effort across our entire database, we’re able to prioritize high-fit accounts, build smarter territories, and run more effective ABM campaigns. It’s made our outreach more focused and our sales teams way more efficient. Review collected by and hosted on G2.com.

There were some dislikes but their team solved them. They even gave me more free credits for testing before purchasing. Now I have subscribed in their annual plan and if everything goes the same, I will renew my account next year, in 2026. Review collected by and hosted on G2.com.

They solved the issues I faced while using this website. They increased my CRM data accuracy and our ROI. Review collected by and hosted on G2.com.
