Build your own ATS

You do not need a $30k platform to run a professional desk. This blueprint shows the minimum system that works, what to automate first, and when to graduate.

Your desk, your system

Use Claude + workflow automation + AIR Blackbox to build a recruiting system that you own, with zero data leakage. No $500/month ATS subscription required.

01

Set Up Your Pipeline Database

Your ATS starts with a structured database. Use Airtable (free) or Google Sheets as your candidate and requisition tracker.

  • Candidates table: Name, skills, status, source, notes, comp
  • Requisitions table: Company, role, JD, priority, submissions
  • Submissions table: Links candidates to reqs with status
  • Activity log: Every touchpoint, timestamped
02

Add AI-Powered Scoring with Claude

Use Claude to parse JDs, score candidates, and generate outreach. Feed JDs and resumes in, get structured evaluations out.

  • JD Parser: Extract must-haves, nice-to-haves, hidden requirements
  • Resume Scorer: Match candidate skills against parsed JD
  • Outreach Writer: Generate personalized messages per candidate
  • Interview Prep: Create prep docs for submitted candidates
03

Wire Up Automation

Connect everything with n8n, Make, or Zapier so data flows automatically between your tools.

  • New req added: Auto-generate sourcing strategy via Claude API
  • Candidate submitted: Auto-update pipeline, notify client
  • No response in 3 days: Auto-trigger follow-up sequence
  • Placement made: Auto-create invoice, start retention tracker
04

Lock Down Data with AIR Blackbox

Candidate data is sensitive. AIR Blackbox ensures your AI workflows don't leak PII, violate compliance, or create audit gaps.

  • Data leakage scanning: Detect if candidate PII is being sent to unauthorized endpoints
  • Compliance checks: Ensure your AI scoring doesn't create bias or discrimination risk
  • Audit trail: Tamper-evident logs of every AI decision for EEOC/OFCCP defensibility
  • Self-hosted option: Run n8n + AIR Blackbox locally so data never leaves your machine

Build Your Dashboard

Pull metrics from your pipeline database into a live dashboard. Know your numbers without manual counting.

  • Funnel metrics: Sourced → Submitted → Interview → Offer → Placed
  • Time tracking: Average time-to-fill by client and role type
  • Revenue: Fees earned, pipeline value, close rate
  • Source quality: Which channels produce the most placements
06

Cost Comparison

Why build your own? Because traditional ATS platforms charge $200-$500/month for features you can replicate for nearly free.

  • Bullhorn/JobAdder: $200-$500/month
  • Your stack: Airtable (free) + n8n (free, self-hosted) + Claude API (~$20/mo) = under $25/month
  • Bonus: You own your data. You control the workflow. No vendor lock-in.
  • With AIR Blackbox: Add compliance and data protection at no extra cost (open source)

Common questions

Can I really run a desk without a commercial ATS?

Yes, up to a real but meaningful scale. A structured sheet plus a few automations handles tens of active roles. The blueprint above shows the exact structure and where it breaks.

What should my ATS track at minimum?

One row per candidate per role with stage, last touch, next action, and source. If you cannot answer "who am I waiting on and since when" in one glance, the system is not working.

When should I move to a real platform?

When handoffs appear: a second recruiter, a client portal, or compliance requirements. Collaboration and audit trails are what spreadsheets do worst.
