Marc Lou says he is hitting $100K a month solo, and labels the figure "pre-Hyrox" to separate it from his sponsorship deals. The same post lists what he is doing with the time: building a longevity app, two meetups, a trip to China.

Tibo says a product flat at $2k MRR for six months just hit $15k

Tibo says his newest product sat at $2k MRR in April, was still $2k in June, went down in August, and is now at $15k after the last 30 days. He says he has been through this more than ten times and it is always the same: stuck until the product fixes the real pain.

Peter Steinberger says OpenClaw deleted around 400k lines of its own tests without much change in code coverage. His explanation: modern models write tests for every tiny change, and if you just tell an agent to clean up, it stops far too early. The fix he posted is a target, not an instruction.
