UserGems is the future of outbound sales. We apply artificial intelligence to help companies identify who to best target for their sales and marketing outreach.

We’re growing 5X year-over-year and recently raised $20M series A from Craft Ventures, Uncork Capital, Battery Ventures, Tiger Global, and more.

And we're looking for a Software Engineer to help build new products and scale our platform.

What is UserGems

We monitor a company’s existing customer list for job changes and alert their sales teams whenever someone moves to a new company.

Each month, our customers get a list of people they should reach out to – identified and ranked by our proprietary algorithm. This algorithm combines thousands of data points to generate the best possible prospecting list, uniquely tailored to them.

Example: Jared was using AWS when he worked at Hooli. Now that he’s working at Pied Piper, he could be interested in using AWS again. We’ll alert AWS’ sales team of Jared’s job change. Jared already knows AWS and might be interested to hear what AWS has to offer for Pied Piper.

What our customers say

"UserGems delivers true, concrete ROI on day one. It has turned out to be one of the most valuable solutions we have added to our go-to-market tech stack in the last two years." - Ben Loeffler-Little, former Head of Sales at Periscope Data
