Case Overview & Background

Simon Bergeron runs Lemonbrand.io, a one-person AI consultancy for teams of 5 to 200 people. His second client, a gym owner, paid a $2,500 lump sum that became a $1,500 a month retainer, and is still a client three years later. He now starts with an inbox audit at about $1,500 and sells retainers from about $2,500 a month.

How AI Is Used

AI agents classify a year of client emails to find repeated tasks. He then builds automations, often as Claude or ChatGPT skills on the client's own accounts, plus n8n or Make workflows.

Step-by-Step Process

Step 01Inbox audit

About $1,500, credited against a retainer.

Step 02Find repeated work

Agents classify emails and map recurring tasks.

Step 03Automate one at a time

Retainer from about $2,500 a month, 90-day minimum.

Customer Acquisition & Distribution

Referrals and local outreach to small business owners.

Limitations, Risks & Failure Modes

What may not apply to you, and what could go wrong:

  • Self-reported per-client prices, not total revenue
  • Inbox access involves sensitive client data and data protection rules
  • Active service work, not passive income

Key Takeaways

  • A low-priced audit can open a recurring retainer
  • Small, steady automations keep clients longer than flashy builds
