DemandScience Reviews & Product Details

The DemandScience team is the best I’ve ever worked with. They’re always quick to respond, clearly know what they’re talking about, and are consistently friendly. My experience with the company has been nothing but positive. I find myself talking with the team and/or using their platform daily, and I really appreciate the range of capabilities it offers. I use DemandScience for display campaigns, content syndication, BANT leads, and CTV. Their integrations team was also a pleasure to work with, and they made the Salesforce tie-in feel effortless.

I still haven’t found anything to dislike about DemandScience. They’re the first external partner I’ve fully trusted, and I never have to worry about shady tactics like impression stuffing or inflating viewability. Review collected by and hosted on G2.com.

We've been collaborating with DemandScience on a content syndication and ABM marketing programme, and our main objectives were to generate leads and engage high-value stakeholders for our clients through multiple channels.

I'm pleased to say that DemandScience have delivered on those objectives. The lead quality has been consistently strong, and we've noticed a real increase in the level of stakeholder interest we've been aiming for. On top of that, the experience of working with the DemandScience team has been excellent: smooth, collaborative, and professional. Overall, we're very happy with the results and would definitely recommend them. Review collected by and hosted on G2.com.

We have been partnering with DemandScience in our Lead Generation program for Avanade for over a year, and they continue to be a highly reliable and valuable collaborator. From the very beginning, Kitti, Alex, and Greg have provided exceptional service, consistently demonstrating professionalism, responsiveness, and deep understanding of our goals.

Their support has been instrumental in helping us generate high‑quality Marketing Qualified Leads, making their contribution essential to the success of our broader demand generation efforts. We also deeply appreciate how easy it is to work with them-their organization, streamlined implementation, and overall ease of integration have made the entire process smooth and efficient.

We highly recommend DemandScience, particularly their BANT programs, which have proven to be an excellent fit for our needs. Review collected by and hosted on G2.com.

I really like the customer experience with DemandScience. They respond very quickly and dealing with the people who work there is very easy. When we need something, they resolve it quickly. When it comes to generating leads, it is very important that the leads are of quality, and when we have any doubts about any data, they fix it immediately and contact us to correct the data, which is very fast and efficient. Additionally, the initial setup process with DemandScience was very easy and quick. Review collected by and hosted on G2.com.

Access to the platform is not direct, as there is no platform you can directly access to view; you have to go through the account manager or the Customer Experience Manager. I think it would be good if they could review this lack of flexibility or customization. Review collected by and hosted on G2.com.

The client servicing team, and specifically Marta De Souza, has been exceptional to work with over the last few months. Marta stands out for her proactive communication and meticulous attention to detail. Despite the challenges of different time zones, she ensures our meetings are highly organized and efficient, consistently covering all necessary items to minimize back-and-forth. Furthermore, her ability to loop in the right stakeholders at the right time has been instrumental in the success of our campaign. Review collected by and hosted on G2.com.

The primary challenge is the time zone difference. While the team is highly organised, the time zone naturally creates a delay in real-time collaboration. This can occasionally slow down the momentum of urgent campaign adjustments, as we often have to wait a full business cycle for a response or a sync-up. Review collected by and hosted on G2.com.

Demand Science has been my preferred partner for display ads and content syndication for several years. They are easy to work with, they deliver excellent results and work in the best interest of my campaigns. They are quick to respond, attentive, have great attention to detail and are always offering suggestions on how we can improve. My senior customer experience manager, Ryan Lopez makes planning and execution easy and I can trust my campaigns are in great hands. Review collected by and hosted on G2.com.

I would like if the content syndication team and the display advertising team are the same so I didn't have to contact multiple people for 1 campaign. Review collected by and hosted on G2.com.

I find DemandScience easy and quick to communicate with. They take on feedback really well. For example, when their lead invalidation rate was a little high one month, they greatly improved the following month. They're open with what stage of lead delivery they're at, produce summary charts showing how their lead pacing is, and always flag questions to gain clarity. The setup for lead delivery with them is smooth sailing. Review collected by and hosted on G2.com.

We've had a few blips with invalidation rates. Sometimes they need longer than recommended to deliver full lead delivery within a quarter, and they often ask to upload leads until the last possible day, instead of our recommendation of uploading a week prior to the end of quarter.

DemandScience has a massive audience that has allowed us to easily match our target audience to generate leads from the exact people we are looking to engage at a reasonable price. We have not found any other vendor that can target the various topics we focus on throughout the year. Review collected by and hosted on G2.com.

Unfortunately, over the 1 year we have worked together we have had at least 3 different account executives managing our relationship. Additionally, their acquisition of Terminus was great until they initiated a very high minimum budget which means we can only do lead generation with them. Review collected by and hosted on G2.com.

What I appreciate most about DemandScience is the combination of precision, data intelligence, and a real commitment to results. The company delivers highly qualified leads, reliable insights, and a level of collaboration that greatly facilitates the execution of marketing and demand generation strategies. The team is agile, transparent, and always open to adjusting deliveries according to the partner's needs — something that makes all the difference in day-to-day operations. For this reason, I consider DemandScience an excellent company to partner with, especially when the goal is to enhance demand generation performance and achieve consistent results.

Variability in the quality of leads, which can sometimes fluctuate according to the campaign or segment, requiring more rigorous review before delivery. Review collected by and hosted on G2.com.

The DemandScience team is fully engaged and very proficient. They are quick to respond and their work is always top notch. We trust their insights and recommendations for our campaigns and appreciate the partnership we have had over the years. Review collected by and hosted on G2.com.
