Sourcing is finding people who could fit a role, especially people who have not applied, by searching profiles, databases, networks and your own ATS. It is the top of the recruiting funnel: the work that creates a list of names before anyone is contacted, screened or interviewed.

Finding people who could fit a role, especially those who have not applied, by searching profiles, databases and networks.
Sourcing covers several methods. Sourcers search professional networks and job board resume databases, run Boolean and X ray searches on Google, mine GitHub, conference speaker lists and association directories, and rediscover past applicants already in the ATS. Newer AI sourcing tools add semantic search, which finds people by what they have done rather than the exact words on their profile.
In many teams a sourcer finds and engages candidates, then hands interested people to a recruiter who runs the process from screen to offer. In smaller teams and most agencies, one person does both. Either way, good sourcing starts from a clear intake: the must have skills, realistic locations and target companies, so the search is focused instead of broad.
Why it matters to recruiters
Many roles cannot be filled from applicants alone, especially specialized technical, healthcare or leadership roles. Sourcing lets you reach passive candidates who are not looking but would move for the right offer. It also gives you control over the quality and diversity of your pipeline instead of waiting on whoever happens to apply to a posting.
An example from a recruiting desk
Three weeks after opening a senior embedded software role, a recruiter has only four relevant applicants. She spends two hours sourcing: a Boolean search on a professional network, an X ray search for conference speakers and a rediscovery search in the ATS. She builds a list of 60 people, sends personalized messages and books eight phone screens within a week.
Tips that help
Agree on must haves and target companies in the intake meeting before you search.
Search your own ATS first, since past applicants already know your brand.
Save searches that work so you can rerun them for similar roles.
Track response rate by source to see which channels deserve your time.
Mistakes to avoid
Sourcing hundreds of names without a plan to contact and follow up with them.
Copying a job description into a search bar instead of building a real search.

What is the difference between sourcing and recruiting?
Sourcing finds and often first contacts potential candidates. Recruiting covers the full process after that: screening, interviews, managing the hiring manager, offers and closing. In large teams these are separate roles; in agencies and small teams one recruiter usually does both.
What is a sourcer?
A sourcer is a specialist who builds pipelines of candidates for open roles, mostly passive ones. They run searches, map talent at target companies, write outreach and hand engaged candidates to a recruiter. Many recruiters start their careers as sourcers or researchers.
How many candidates should I source for one role?
It depends on the role and your response rates. Work backward from your own numbers: if one in five people replies and one in four of those passes a screen, you need about 20 sourced names for each qualified screen. Track your rates to set targets.
