Jingkai Builds

Small, useful businesses — built by one person.

Jingkai Builds is my group: I start small businesses that solve real problems for real people. No pitch decks, no blitzscaling. If a business doesn't earn its keep, it doesn't survive.

Businesses

One live, one in the lab. Each one has to pay for itself.

02 — In the lab

Exploring · practical software for CNC machinists

Years at the machine teach you what software should do. Small tools for Swiss-type shops — quoting, setup, process planning. Nothing to sell yet; building in the open.

How I build

Three rules, for every business under this roof.

  1. Small scope, fixed priceIf I can't name exactly what you get, I don't sell it.
  2. You own everythingYour accounts, your files, your data. No lock-in, no ransom.
  3. Talk to the builderNo sales team. You email me, I build it.
