An agent stack map for a solo SaaS founder
A map a solo founder can review before trusting agents with the company: each agent’s job, how its work is checked, what it may spend, and when it must stop and ask. The company and figures are invented.
- Before
- Everything runs through the founder’s inbox. Support replies wait until evening, billing errors surface when customers complain, and deploys happen only when Sam is awake.
- After
- Five supervised agents carry the routine, each with a written check, a budget cap and a stop rule. The founder sets data access, reviews exceptions and approves financial actions.
Inspect the sample
01 Input
Sam Ortiz, a fictional solo founder, runs Lintwise, a developer tool with paying customers. Sam answers support, ships code, runs billing and writes the investor update, and a failed deploy at 3 a.m. is Sam’s alone.
How it moves
- List the jobs Write down every recurring job in the company and how often it happens.
- Assign or keep Give routine, checkable jobs to agents. Keep judgment, money and relationships with the founder.
- Set checks and budgets Each agent gets a repeatable check the founder can inspect and a monthly spending cap.
- Write the stop rules Each agent stops and alerts the founder at a named condition, such as a refund request or a failing test.
02 Output
| Agent | Job | How it is checked | Monthly budget cap | Stop rule |
|---|---|---|---|---|
| Support | Answer documented how-to questions | The founder reads a daily sample of ten replies | $300 of model usage | Any refund, outage or upset customer |
| Release | Run the tests and prepare deploys | CI must pass; the founder approves each production deploy | $150 of model usage | Any failing test or database migration |
| Billing | Flag failed payments and draft reminders | The founder approves reminders each week | $50 of model usage | Any plan change or refund |
| Research | Summarize competitors’ changelogs | The founder skims the weekly summary | $100 of model usage | Any claim without a source link |
| Investor update | Draft the monthly update from metrics | The founder rewrites and sends it personally | $20 of model usage | Never sends anything; drafts only |
03 Review
Where a person decides
The founder approves every production deploy, every refund and every message to an investor. Agents draft and prepare; nothing that cannot be undone happens without the founder’s yes.
Limits of this example
Fictional company and figures. Budgets and stop rules depend on your product and your risks. Billing touches payment records, which Build Plus lists; we confirm the level when we scope it. Not investment, legal or tax advice.
