One person runs 8 businesses with Claude, n8n and Supabase
In plain words
Lewie uses n8n for content, client reports, lead routing and monitoring, Supabase as a shared database, and Claude for analysis and code.
What happened: Eight businesses run by one person, with AI doing the repeat work.

How to do it yourself
Our suggested steps. The company didn't publish theirs.
- 1
Put all leads from every site/form into one Supabase table.
- 2
In n8n, send each new lead to Claude with the prompt below to score and tag it.
- 3
Route hot leads to your phone, the rest to an email sequence.
- 4
Add a daily uptime/error check for your sites.
- 5
Review the lead scores weekly and tweak the prompt.
The instructions to give the AI
Paste this into Claude (the free plan is fine), swap the [brackets] for your details, and test it on a few real examples.
This is one part of the setup. It won't connect to your phone, inbox or other apps on its own; the steps above cover that.
Agent instructions (prompt)
Score this lead 1-10 for [business list]. Say which business it fits, why, and the next action (call now / nurture / ignore). Return JSON: {business, score, reason, action}.
Lead:
[paste][Highlighted] = replace with your own details before you run it.
What you should get back: "8/10 — fits the cleaning business: 3 locations, hiring. Next: call today."
