Sidedoor Review: Find Hidden Job Referrals Through Gmail, LinkedIn & Your Network

Sidedoor is a free job-search tool from Happenstance that helps you find possible referrals before applying to a job. Instead of sending cold applications, you paste a job posting, and Sidedoor searches across your connected network, including Gmail, LinkedIn, Instagram, Twitter/X, Outlook, and friends’ connections, to show who may be able to introduce or refer you. This can be useful for job seekers because referrals often perform better than cold applications. The tool is especially interesting if you have a large network but do not know who is connected to a company. Important Note : Sidedoor may require broad account access to search your network. Happenstance’s privacy policy says Google data access includes Gmail headers, not email bodies or attachments, but users should still review permissions carefully before connecting accounts.
