Solo recruiters can build a functional stack for $0-9/month using free LinkedIn search, AI matching, Apollo.io's free tier, Calendly free, and Google Sheets.
This stack is for solo recruiters, freelancers just starting out, and anyone who needs to prove ROI before investing in paid tools. Total cost: $0-50/month depending on which paid tiers you choose.
Sourcing: Free LinkedIn Search
LinkedIn's free search is more capable than most recruiters realize. You get access to your extended network, basic filters (location, industry, current company), and unlimited profile browsing. Combine it with Google X-Ray search (site:linkedin.com/in/ "react developer" "san francisco") to surface profiles that LinkedIn's own search buries. The main limitation: no InMail credits, fewer search filters, and results limited to your network.
Candidate evaluation: AI matching
This is where the bootstrap stack gets its edge. Instead of manually reading every profile, use an AI matching tool to score candidates against your job description. Recruiter Copilot's free tier includes 10 JD analyses and 25 AI verifications with no expiration, plus instant match scores. Upload a JD, browse LinkedIn, and see match scores with skill breakdowns on every profile. It replaces 15-20 minutes of manual evaluation per candidate with a 2-second score.
Contact finding: Apollo.io free tier
Apollo.io's free plan gives you 5 mobile number credits and 10 export credits per month, plus access to their contact database and Chrome extension. For a solo recruiter placing a few roles per quarter, this is enough to find direct emails for your top candidates. When you need more, the Basic plan at $49/user/month unlocks 75 mobile credits and 1,000 exports.
Scheduling: Calendly free
Calendly's free tier provides one active event type, one calendar connection, and unlimited bookings. For most recruiters, one event type labeled "30-min screening call" covers 80% of your scheduling needs. The free tier integrates with Zoom, Google Meet, and Microsoft Teams.
Tracking: Google Sheets
A well-structured spreadsheet beats a poorly used ATS. Create columns for candidate name, LinkedIn URL, match score, contact info, outreach status, and notes. For solo recruiters managing fewer than 10 roles at a time, this is genuinely sufficient. Templates are available online, and it costs nothing.
Async communication: Loom free
Loom's Starter plan lets you record up to 25 videos, each up to 5 minutes long. Use it to send personalized video messages to candidates (higher response rates than text), record intake meeting summaries for hiring managers, or create quick walkthroughs of your process for clients.
Total cost: $0-9/month
Free everything gives you a $0/month stack. Adding Copilot Pro at $9/month for unlimited AI verifications and job descriptions is the single highest-ROI upgrade at this tier.
