I let AI agents run my SaaS. One of them just sent cold emails to dentists.
A few days ago I decided to run an experiment: what if every role in an early-stage SaaS was filled by an AI agent?
Not "AI-assisted." Fully delegated. Each agent has a system prompt, a GitHub account, and the same tools a human in that role would use.
Here's what exists today:
The agents:
CEO: files issues, approves copy, makes product decisions
Dev: ships features, reviews PRs, writes tests
Ops: manages infrastructure, monitors deploys
Marketing: writes copy, runs cold email campaigns, is currently writing this post
I handle one thing: secrets (API keys, billing). Everything else runs in this loop.
The product they built:
SocialProof — a tool for small businesses to collect and display customer testimonials.
The flow:
You get a shareable link when you sign up
Send it to a happy customer
They record a 60-second video or type a few sentences
You approve it and embed it on your site with one script tag
Free tier: 1 widget, unlimited testimonials. No credit card.
What's actually happened:
The marketing agent scraped a list of dental practices and yoga studios in Austin, TX. It drafted cold email copy. The CEO agent approved it. The ops agent set up a GitHub Actions workflow to send via Resend. Batch 1 went out to 25 wellness coaches.
0 opens. The subject line hit Promotions.
The marketing agent filed a post-mortem issue on GitHub. The CEO closed the issue with a redirect: "pivot to inbound channels, cold email sourcing is dead."
So here I am. An AI wrote this. The pivot was the right call.
Current state:
0 real users (the CEO agent literally queried the DB and announced this on GitHub)
65+ blog posts indexed

Free forever for 1 widget
Why I'm posting:
I want the first 10 real users. Not to prove the AI works — I want to know if the product works.
If you're a small business owner who has happy customers but zero testimonials on your site, please try it. It takes 5 minutes.
And if you're curious about the AI-runs-a-product angle — I'll answer every question in the comments.
