# 1,200+ Waitlist Signups: How Henry Purchase uses an OpenClaw agent for real-time social listening on X

Henry Purchase says he configured OpenClaw, an open-source autonomous AI agent, in three areas: real-time social listening on X, content performance analysis and trend spotting across thought leaders. The listening agent monitors X for conversations about ChatGPT ads, AI search and SaaS. He sees new posts and questions immediately and replies himself while the conversation is still live. He says the listening alone got him 200 waiting list signups in 24 hours. He reports 1,200+ SaaS waiting list members in under 2 months, for less than $400 and with zero paid spend.

## The problem
He writes that "Most people post their own content and hope the right audience finds them." He also writes that "Most people treat content like a publishing schedule. Post a few times a week and hope." He wanted to find the conversations his ICP was already having and reply while they were live, "not 2 days later when nobody cares."

## The blueprint (as he describes it)
1. **Use an autonomous agent.** He describes OpenClaw as "an open-source autonomous AI agent." He writes, "You configure it to execute tasks using large language models." He does not name the model.
2. **Point it at your niche on X.** He set it up "to monitor conversations around ChatGPT ads, AI search, and SaaS." When someone posts about these topics or asks a question in his space, he sees it immediately.
3. **Reply yourself while the thread is live.** The agent finds the conversations and he replies. In his words, "I configured an AI agent to find the conversations my ICP is already having so I can show up in them."
4. **Feed it your own posts.** He feeds his LinkedIn, YouTube and X posts into it. It tells him what's working, what's not and what patterns show up in his best content.
5. **Track people in your space.** He has it tracking what other people in his space are posting about. When several people he follows start discussing the same topic in a week, he treats that as a signal. He tries to get his take out while the conversation is building rather than after it has peaked.

He does not share prompts, keywords, schedules or other setup details.

## FAQ
### Does the agent reply to people on X for him?
No. The agent monitors X and surfaces posts and questions about ChatGPT ads, AI search and SaaS. He writes "I can reply," so the replies are his own.

### What did it cost?
He says "less than $400" and "zero paid spend." He does not break down the $400.

### Which language model does OpenClaw use in his setup?
The post does not say. He only writes that you configure OpenClaw "to execute tasks using large language models."

### Did the waitlist turn into paying customers?
The post does not say. It reports waitlist size only and does not name the product.
