Build custom AI agents for businesses — customer support, research, scheduling, data processing, and complex workflow automation

Skills to bring or develop

  • Python/JavaScript

Find your first customers

Treat this customer profile as a starting hypothesis. Talk to people in this role and find out what they already do, what it costs them, and whether they want help.

Role

CTO / VP Engineering

Company size

20-200 employees

Industry

SaaS / Tech

Problems to investigate

  • Team too busy for AI R&D
  • Chatbot doesn't handle complex scenarios
  • Manual processes that should be automated
  • Can't hire AI/ML engineers (too expensive)
  • Need custom AI, not generic SaaS tools

Channels to test

  • LinkedIn
  • Content Marketing
  • Communities
  • Partnerships

First launch approach

Build 3 open-source demo agents, write technical blog posts, speak at AI meetups

Ways to find your first customer

  • Build and open-source a useful agent (e.g., email triager, meeting scheduler)
  • Write technical deep-dives on agent architecture
  • Present at AI/ML meetups and conferences
  • Partner with dev agencies who don't do AI
  • Target companies already using AI tools but want custom solutions

Content ideas

  • AI agents vs chatbots: what's the difference?
  • Building a customer support agent that actually works
  • Why your AI chatbot should be an agent instead
  • Real-world ROI from AI agent implementations

Client onboarding

Step

Map the current manual process end-to-end via screen-share before proposing any agent design

Who handles it

you

Step

Client identifies which systems the agent needs access to (email, CRM, database, APIs)

Who handles it

client

Step

Confirm data sensitivity level — some data may require on-prem or restricted-model handling

Who handles it

client

Step

Build and test in a sandboxed environment with fake/sample data before touching production systems

Who handles it

you

Kickoff conversation

  • Walk through the current manual process, step by step, screen-share required
  • Identify the specific trigger and desired end-state for the agent
  • Surface edge cases: what happens when the agent hits ambiguous or missing data
  • Agree on the human-review checkpoint, if any, before the agent takes consequential actions

Your launch roadmap

Work through the phases at your own pace. Durations and task hours are estimates; client conversations, sales, and other outcomes depend on the response you receive. Growth and exit steps are optional later decisions.

Tools, budget & effort

These are tools named in the original playbook, offered as examples to evaluate. Check current capabilities, pricing, licensing, and data handling with the provider before subscribing. Start with the tools you already have.

  • Claude API
  • OpenAI API
  • LangChain
  • n8n
  • Supabase

Tools to evaluate

Item

Claude/OpenAI API accounts with billing set up

Why consider it

This is the actual product — you cannot demo or build without live API access

Item

An orchestration framework (LangChain, CrewAI, or similar)

Why consider it

Rebuilding agent scaffolding from scratch per client burns the margin this business depends on

Item

A staging environment separate from client production

Why consider it

The #1 mistake new agent builders make is testing against a live client system — one bad tool call can break something real

Make the numbers your own

Include setup, subscriptions, selling, fulfillment, revisions, support, and your time. Use your actual inputs and compare a cautious case with a better case.

Your first small test

  1. Choose one customer. Find five people who have the problem described in this guide.
  2. Show one useful sample. Ask about their current process, priorities, and objections.
  3. Offer a clearly scoped pilot. Agree on deliverables, a price to test, and what success means.
  4. Record the evidence. Track responses, costs, hours, and what the buyer actually used. Decide whether to continue, change, or pause.
