AI systems for builders · course, skills, templates
BuildLeanSaaS teaches founders how to wire Codex, Hermes, GitHub, cron, and approval loops into repeatable workflows that actually ship.

Today's operating loop
Output delivered: sourced brief, scoped issue, draft, QA notes, and next action.
Built around real operating loops
Why this exists
A prompt demo is not a business process. A useful system has inputs, state, tools, checks, approvals, logs, and a repeatable output.
This site exists to help builders turn AI agents into practical loops for the work they already repeat: content, research, client ops, product tasks, SEO, and founder PM.
How we operate
Name the input, the owner, the approval point, and the business outcome before touching tools.
Use the course, checklist, skills, and templates as the scaffolding for the first working loop.
Wire Codex, Hermes, GitHub, Discord, cron, and human review so the system can run safely.
Review outputs, patch weak spots, and turn one working workflow into the next one.
What you get instead
BuildLeanSaaS keeps the attention on the operating loop: what comes in, what the agent does, what a human approves, and what gets delivered.
Start path
The first BuildLeanSaaS track walks you from a small VPS to a Discord-controlled agent workflow that captures inputs, creates work items, and reviews the day.
Starter kit
Start with the guided path, then pull in the skills and templates that match the workflow you are building.
Course
Build the first practical always-on agent system from VPS setup to Discord control room and daily review loop.
Start courseChecklist
Use the checklist to map inputs, state, tools, approvals, delivery, and reporting before you build.

Install skillWhere it applies
Watch sources, dedupe updates, score what matters, and create sourced drafts.
Capture ideas and asks in Discord, shape them into issues, then report what moved.
Turn a scoped task into a branch, checks, review notes, and production smoke receipts.
Summarize requests, draft replies, prepare docs, and keep sends approval-gated.
Capture signals, enrich context, score opportunities, and keep the trail inspectable.
Automate the busy loop without hiding decisions, credentials, or irreversible actions.
Questions
You should be willing to follow technical steps, but the first path is written for builders who want practical operator guidance, not abstract engineering theory.
BuildLeanSaaS is the education, skills, and template layer for building Systems as a Service. Some pieces are public guides, some are Pro assets, and some point to implementation help.
Start with Always-On Agents if you want the guided build. Use the starter checklist if you want to understand the system pieces before committing.
BuildLeanSaaS Pro unlocks the launch bundle of agent courses, premium skills, templates, and future system updates. The current launch deal is linked from the banner and course pages.
Yes. DevelopJoy is the setup and implementation support path when you want help connecting the loop to your tools, repo, and operating cadence.
