Leadyol runs on your own computer. Pick a business category and a place, and it builds a list of businesses from open, licensed data. It then reads each business's own public website for emails, phones, WhatsApp links and social profiles, checks the emails, removes duplicates and exports Excel or CSV. Open data is not 100% complete, so coverage varies by country and industry. It lists public business information: follow each country's law and your do-not-contact list.
