FAQ

ZoomInfo focuses on providing extensive business data and advanced analytics, making it suitable for larger enterprises. Seamless.ai, on the other hand, emphasizes user-friendly prospecting tools and real-time data updates, catering to startups and small businesses. Both platforms have unique strengths tailored to different market needs.

The key points of differentiation between ZoomInfo and Seamless.ai are that the former targets enterprise-level sales intelligence that is <95 % accurate and supported by 350+ native integrations, whereas Seamless.ai targets real-time lead generation with accurate date information at a cheaper price, an easy-to-use interface, and free or low-priced credit plans.

The AI-plus-human verification that ZoomInfo uses makes sure that the levels of data precision with its contact and business records are beyond the 95 % indicator. The accuracy of seamless.ai is in the range of 60-70 %, but its real-time engine is used to bring out newer data at a higher rate.

Yes, even though LinkedIn had blocked direct access to pages, Seamless.ai used alternative ways to collect data, i.e. by using public websites and job boards, as well as in web crawls. The frequent users of the LinkedIn Sales Navigator might observe the blank spaces, though the daily prospecting remains important due to the updates of buyer intent and Chrome extension.

Seamless.ai carries the advantage on the pricing front: an unlimited free package (50 credits/month) and a Pro one at 299 dollars per user per month. The cost of the entry-level Professional edition in ZoomInfo is almost 15 k, and it is the more suitable option with higher budgets and more complicated sales that require such a solution.

ZoomInfo also provides 350+ native integration with CRMs (Salesforce, HubSpot, Marketo, and others), which makes it an excellent choice of enterprise tech stacks. Seamless.ai has roughly 15 primary integrations, such as Salesforce and HubSpot, which is enough to work in groups of a smaller size and need fast-track processes that can be used right after connecting to them
