Datanyze vs TechnologyChecker

Datanyze is a Google Chrome extension for finding B2B contact details and company information while prospecting on sites such as LinkedIn. It provides contact and company data in real time, including email addresses and direct dial phone numbers. Its coverage figures include 63 million direct dials, 84 million email addresses, and 120 million people. Users can tag contacts and companies, create segmented lists, and export them as CSV files. When viewing a company’s employees on LinkedIn, the extension can provide their contact information on the page. Directory pages feature icebreakers drawn from personal social media feeds, local news publications, and other sources. One credit reveals one contact’s information, usable through the extension or directory pages. The product lists technology detection, company profiles, historical technology data, and technology intent signals. Nyze Lite offers 10 credits per month during a 90-day trial. After that trial, access to the platform and previously revealed contact details ends unless the user upgrades. Monthly paid options include Nyze Pro 1 at $29 a month for 80 credits and Nyze Pro 2 at $55 a month for 160 credits.
