In the world of recruitment, access to a vast and high-quality candidate database is the pillar of successful talent acquisition campaigns. Recruiters navigating the talent ocean often find themselves competing to discover, connect with, and source top-tier candidates through LinkedIn. 

Since recruitment’s move into the digital age, LinkedIn has developed somewhat of a monopoly on networking. Today the platform boasts over 900 million users worldwide – 11.5% of the earth’s population – and it would be hard to find a professional, especially in Tech, that doesn’t use LinkedIn.

Owning a monopoly on networking has also enabled LinkedIn to covertly increase the price of LinkedIn Recruiter to the point where a recruiter license is now a staggering $10,800 per year and a single InMail message sets you back $10.

It’s no wonder recruitment businesses are turning to alternative platforms.

There is more to the recruitment world than just LinkedIn, and here we’ll delve into other platforms that can enrich your recruitment database.

Here are the several types of recruitment databases we’ve listed in this blog:

  1. Job boards
  2. Social Media Platforms
  3. Freelancer Marketplaces
  4. Other Platforms

1. Job Boards

Job boards can be a great way to find relevant profiles for your recruitment database. According to Glassdoor, when candidates are on the hunt for a new job, they’ll use 8 different job boards on average. Most job boards are free to use for applicants, so finding profiles for your database here can be worth the time.

Here are some of the best ones:


Indeed is arguably the most popular job-specific platform on the web with over 200m registered CVs. Recruiters can post jobs for free on Indeed, and have tons of candidates apply to the job ad in the general search. Upgrading to premium gives you access to a wide range of features such as: 

  • Reaching more candidates with a boost to your job ad

  • Creating a personalized company page layout with custom branding
  • Measuring candidate engagement with analysis of job applications and company reviews

In addition to the premium feature, you can buy extra boosts for your job listing and integrate the Hiring Platform directly to your ATS to automate extracting profiles of applied candidates. 

Indeed can be a very effective tool to source data from relevant candidates who don’t use LinkedIn.

Database: 200m CVs


Glassdoor started off as a platform where current and former employees can anonymously review companies. As more and more job seekers signed up to the platform to view the reviews of a company before applying for a job, it has now become a leading job board due to its transparency of salaries and company reviews.

Glassdoor allows recruiters from verified companies to post jobs, advertise their company page, and get access to millions of candidates. 

There is a focus on employee branding and marketing, giving you the chance to showcase your company and build trust with candidates organically.

Database: 57 Million unique users per month. 


Monster is another popular job board with candidates and recruiters alike. Recruiters can join Monster, post a job, and gain access to advanced algorithms that enable the matching of candidates with job postings. The database is enriched with tons of candidates across various industries.

Monster leans more on automating the process of candidates to relevant job descriptions.

Database: 70 million users worldwide

2. Social Media Platforms

While LinkedIn is a primary player, especially on the professional front, other social media platforms shouldn't be overlooked.

Now it may not be the most conventional way to source candidates, but social media can be a dark horse when it comes to getting profiles.

There are two platforms that are worth giving some attention to:


Polywork is a modern professional networking platform – leaning towards tech– designed to showcase the all-around nature of individuals in their careers. Launched with the vision of moving beyond traditional resumes, Polywork empowers users to highlight their diverse skills, projects, and achievements.

Recruiters can create a profile and search for candidates who are open to collaboration and partnerships.

Twitter needs no introduction. But its utility in finding and contacting potential candidates may be worth mentioning. When used properly, it can become a dynamic space for professional networking, talent sourcing, and employer branding.

There are some key features worth adding to your recruitment arsenal:

Real-Time Updates:

Twitter's real-time nature allows recruiters to stay current with industry trends, job market dynamics, and engage with a dynamic audience actively participating in professional discussions.

The use of hashtags enables recruiters to amplify the reach of job postings. Targeted and industry-specific hashtags increase visibility among professionals interested in specific roles or industries.

Twitter offers advertising options for companies to promote job listings or employer branding campaigns to a wider audience. 

Although Twitter may not be the first choice, it can be a useful alternative to LinkedIn.

Database: 368m monthly users

3. Freelancer Marketplaces

With the workforce leaning towards a freelancer revolution, which will become a majority by 2030, freelancer marketplaces are a great place to discover untapped talent.

Here are some of the best ones out there:

Stack Overflow

Stack Overflow is a go-to platform for software developers looking for solutions and knowledge-sharing on everything involving coding. The platform has a Q&A-style forum where developers post threads of coding challenges and tips.
