Relevance AI is the most powerful platform for building custom multi-agent workflows. This guide walks through building your first agent team — from initial setup to production deployment. Expect 1-2 weeks from setup to your first production workflow.

Step 1: Sign up and choose a plan

Sign up at relevance.ai. Start with the Free tier (100 runs/month) for evaluation. Upgrade to Pro ($400/month) when you're ready for production.

Step 2: Understand the architecture

Relevance AI uses a multi-agent architecture:

  • Agents: Specialized AI workers with defined roles
  • Tools: Functions agents can call (APIs, databases, etc.)
  • Workflows: Multi-step processes that chain agents together
  • Handoffs: How agents pass work to each other

Step 3: Build your first agent

Start with a simple single-agent workflow:

  1. Create a new agent
  2. Define its role: "Research target companies matching ICP criteria"
  3. Add tools: web search, Apollo API, LinkedIn API
  4. Configure the prompt with ICP criteria
  5. Test with sample inputs

Step 4: Build a multi-agent workflow

Once your first agent works, chain it with others:

  1. Agent 1 (Researcher): Find target companies
  2. Agent 2 (Enricher): Find decision-maker contacts
  3. Agent 3 (Writer): Draft personalized outreach
  4. Agent 4 (Sender): Execute email sequence

Configure handoffs — Agent 1's output becomes Agent 2's input, etc.

Step 5: Configure safety

Before going live:

  • Spending caps: Set monthly limits in billing settings
  • Alerts: Configure alerts at 50% and 90% of cap
  • Approval steps: Add human approval for external communications
  • Audit logging: Enable for all agent actions

Step 6: Test and deploy

Test in sandbox mode with sample data for 1-2 weeks. Once confident, deploy to production with close monitoring for the first month.

Common mistakes to avoid

  • Building too complex a workflow initially
  • Not setting spending caps (a runaway agent can rack up significant charges)
  • Skipping sandbox testing
  • Not monitoring agent performance post-deployment
