this OpenClaw bot finds $500k–$1.2M homes without pools, renders a pool into their backyard, and mails the owner a postcard showing the before/after, on autopilot...
here's how pool builders can close $50k+ deals with this system:
- scans satellite imagery for mid-market homes with empty backyards
- filters by lot size, sun exposure & recent ownership change
- pulls the homeowner direct from public records (not shared leads)
- renders a luxury pool dropped into their actual yard
- calculates build cost + home value lift for their specific zip
- generates a cinematic video of their backyard with the new pool
- prints a personalised postcard with the before/after + QR code
- drops it in the mail + hits them with retargeting
every step from sourcing to outreach is automated.
reply "POOL" + RT and i'll send you the full breakdown so you can build this too (must be following so i can DM)

Pleased to announce Hubert is joining Akatos as a resident for Summer ‘26!
He wanted to leave SF and move to the best city in the world for people building things:
Waterloo, Canada.
We even have French immersion schools for his kids.
Welcome to @akatoshouse, @hthieblot!

Hubert Thieblot@hthieblot
I’m leaving SF. Everyone’s cosplaying as founders. Very few are actually building. Finito. I’ve been here for 19 years. Will miss the views and the weather. If you were starting today, where would you go?

@zarazhangrui We need to start training our focus as if training our muscle. Tens of thouasnds of jobs will be created. Think the bright side.

My single biggest pain point right now: AI-induced attention deficit
I have 5 Claude Code sessions running
10 Terminal tabs open
50 browser tabs open
100 X articles in my bookmarks
When there are multiple AIs working for you, you're constantly task switching
When you're waiting for AI to output, you're constantly distracted
Because what used to be hard is now so easy, you always wanna do more, more, more
Because of the speed of the AI news cycle, you feel a constant need to be on this app
Add all this up and the result: you live in a constant state of distraction & delirium. Focus & deep work is harder than ever
If anyone has figured this out pls teach me how

We built Claude Code for Lead Generation…
We hit #1 on @ProductHunt & took @origamichat from slow growth to 2x MRR every week since
I wrote up the exact guide we used to hit #1 and get thousands of users to sign up in a day.
Complete blueprint to #1.
I’ll dm it to you
Just comment “Launch”
RT so other founders get the blueprint

@Gusarich I feel like I am actively getting dumber.
LLMs get brain rot and it is measurable:
llm-brain-rot.github.io
"continual exposure to junk web text induces lasting cognitive decline in large language models (LLMs)" why shouldn't the same be true for brains.

Finding myself going back to RSS/Atom feeds a lot more recently. There's a lot more higher quality longform and a lot less slop intended to provoke. Any product that happens to look a bit different today but that has fundamentally the same incentive structures will eventually converge to the same black hole at the center of gravity well.
We should bring back RSS - it's open, pervasive, hackable.
Download a client, e.g. NetNewsWire (or vibe code one)
Cold start: example of getting off the ground, here is a list of 92 RSS feeds of blogs that were most popular on HN in 2025:

Works great and you will lose a lot fewer brain cells.
I don't know, something has to change.

Waterloo is about to get very loud.
Hundreds of devs talking to their laptops.
AI Agents Waterloo Voice Hackathon will happen in mid February in our region.
Imagine this:
- One table arguing with an agent about pricing too low.
- Another teaching an AI receptionist how to test different prices.
- Someone in the corner debugging why their bot refuses to stop talking.
This is my favorite kind of chaos.
As a Waterloo grad who has spent the last few years bouncing between local builders and the Silicon Valley agent hype, it is surreal to watch voice go from "sci fi demo" to "of course my workflow starts with a mic".
I still remember when talking to your computer in public meant you were either on a Zoom call or slightly unwell.
Now it is just called shipping.
I will be on the judging side this time.
If you are a builder who has been meaning to "try this voice thing properly", this is your excuse.
Come build.
Say hi.
