Run content, leads and monitoring for a tiny agency on four AI agents

A one-person tech agency in Taiwan says four AI agents handle social posts, comment replies, lead flags and monitoring on a free Gemini tier for about $5 a month.

What they did

The owner runs four agents on OpenClaw that draft and quality-check social posts, auto-reply to comments, run research feeds, flag stale leads and monitor endpoints. They use Gemini 2.5 Flash's free tier.

How it went

The owner says about 7% of the free daily quota is used, that his Threads accounts reached 3.3 million views, and that it costs roughly $0 in model fees plus about $5 for infrastructure.

Worth knowing

These are the owner's own claims in a Show HN thread. He declined to share revenue, admitted posting drafted replies in batches, and reported a $127 bill and an engagement loop that burned 800 requests in a day. Commenters doubted the content's value.

Try it yourself

Paste into ChatGPT, Claude or another AI assistant and fill in the square brackets.

I run a [type of small agency]. List the routine marketing tasks I do each week, then propose which an AI could draft and which need me. For each drafted task, set a limit on how often it can post or reply. Show me the plan before anything is published.
