Elucify is a quick and easy way to find contacts at a variety of companies.

You can either sign up for their $99/month plan, or share your business contacts with them. Those contacts then get added to the database which other people can sift through.

Elucify allows you to create lists of contacts by filtering companies by:
company size
technologies used
funding
location

You can also filter the contacts you want by their role at the company. For example, you can filter your list to only get Marketing VPs, or Sales Managers.

Elucify allows you to download 100 leads for free every week. They allow you to download up to 500/week if you share them on social media, though!
