Sidedoor maps networks for warm job referrals
Sidedoor is a free job search tool powered by Happenstance (YC W24) that maps a user's connections across Gmail, LinkedIn, Instagram, Twitter, Outlook, and their friends' networks to surface warm referral opportunities. By analyzing a pasted job description, it identifies both direct and second-degree connections who can refer the candidate, helping them avoid cold applications.
A practical tool addressing job application friction by mapping second-degree network connections for warm introductions.
* Cross-platform mapping integrates social media, email, and contact data into a unified, searchable network map.
* Leveraging friends' connections creates a cooperative network effect that expands referral opportunities beyond standard LinkedIn networks.
* Accessing multiple personal accounts (Gmail, Outlook, social media) raises significant privacy concerns that may hinder user adoption.
* Offering the tool entirely for free makes it highly accessible for active job seekers.
