Seamless has coverage of small, medium and large size companies. We have many data sources that allow us to cover businesses of all sizes, in many different industries, and we are constantly adding to that coverage as well.
We have a free package that allows you 50 credits a month, so you can certainly sign up and test with those credits on the coverage. We would love to hear your feedback and results as you get started. You can also connect your email (outlook, gmail), CRM (Salesforce) and add the chrome extension for social searching as well.
We look forward to helping you fill your pipeline with Seamless.ai!
