    Prospecting corporate accounts near a hotel location. Our sales manager wants to generate a list of companies within a 5 mile radius that may need regular lodging for employees or contractors. D&B Hoovers will allow her to filer by geography, industry, company size and employee count. Then she can view detailed company profiles and contact decision-makers.

    Cons
    Dun Bradstreet
    • I think maybe if they vetted the contacts that they're providing for those companies, it would be beneficial because I do use other avenues to vet the contacts because a lot of times I found that it is outdated information in D&B Hoovers, so that would be beneficial to us.

    I use D&B Hoovers very frequently and could not do my job as efficiently without it. I think there is room for improvement, but it is effective enough that I feel as though I will continue renewing by subscription. I highly recommend D&B Hoovers and find it very accurate and easy to use.

    Whenever I had to use D&B hoovers, I never had a hard time with getting what I need. Additionally, when I show the tool to others, they tend to understand the platform quite quickly. The tool itself is very good and straightforward when I use it to help me put analyses together.

    Performance
    Dun Bradstreet
    While the platform generally functions well, with pages loading in a reasonable time and reports completing within a satisfactory timeframe, there is room for improvement. Performance can sometimes lag with more complex queries or during peak usage times. Additionally, when integrated with other software or systems, there can be occasional slowdowns. Overall, while it performs adequately, optimizing speed and integration efficiency could enhance the user experience.

    I think it could be better, easier and faster. Whenever I chat with someone it takes so long to get to an actual agent, and then when I finally get to one, they oftentimes don't have the answers for me or do not understand what I am asking, which is very frustrating.

    Online Training
    Dun Bradstreet
    The training sessions were well-structured and covered the key functionalities of the platform, making it easy to get up to speed. The trainers were knowledgeable and responsive to questions, which added value to the learning experience. However, a bit more in-depth coverage of advanced features and use cases would have made the training even more beneficial.

    for our use case, the implementation was minimal and we did not need a lot of help. The D&B Hoovers platform is pretty intuitive and our account manager was ready for any questions that came up when we use the D&B Hoovers platform

    Finance Analytics provides a more thorough company credit report and is more in-depth than Hoovers. However, I use Hoovers for instances where I do not need that information because it allows unlimited queries, whereas you pay for a limited number of reports from Finance Analytics. Hoovers provides a better link between corporate family trees and finance analytics.

    Contract Terms and Pricing Model
    Dun Bradstreet
    The pricing model is generally clear and competitive, but there could be more flexibility in terms of unit pricing or billing frequency to better accommodate varying needs. While the contract terms are straightforward, exploring more options or customizable plans might enhance the overall value.

    D&B Hoovers is quite effective at adapting to the needs of different departments and locations, allowing for flexible deployment and integration across various parts of an organization. While it scales well and supports a broad range of users and functions, there might be some limitations depending on the size and complexity of the organization’s requirements.

    Return on Investment
    Dun Bradstreet
    • D&B Hoovers allows me to make the most of my time when searching for companies within specific industries. Once I find a company and examine their profile, I can then generate a list of employees in the purchasing and engineering departments. The profiles for each listed employee contain cell phone, Email address and LinkedIn profile. This information helps me to bypass the companies front desk and get directly to the people I need to speak with.
    • By knowing the specific job title for the people that I am contacting and then being able to click on their LinkedIn link to learn a little about them before I make the call, I come across as a sales professional instead of an impersonal cold-caller.
    • In cases where I do need to go through a front desk receptionist whose primary mission is to screen out sales people, I find that three out of four times the receptionist will connect me to the specific employee because I know their name, department, and job title. The Intel provided by D&B Hoovers makes it possible for me to get to the people I need to speak with.
