Lightweight Shadow SaaS Discovery for Small Businesses is a startup idea for sysadmins and small-business owners. A one-person IT team at a 20-person agency can't track who signed up for which new SaaS, even though it's formally an HR policy question. A thread in r/sysadmin drew 24 upvotes and 50 comments between Sep 14, 2026 – Oct 14, 2026. People get by with Zylo, Torii, and Productiv, and that still leaves this job open. Hotness is 3.20, Warm. Real but moderate pain. Clear willingness to pay. The thread drew 24 upvotes and 50 comments. Gaps in existing tools. A few weeks of work. A first version is a moderate amount of work, about 3–4 weeks, priced between $50 and $199 a month and charged as a B2B subscription. The pain, the source, the alternatives, the scope notes, and the questions on this page are free to read and free to build from. The agent starter prompt is the paid part. The first slice is on the page. One credit unlocks the rest, to paste into a coding agent, download as Markdown, or send as a private link.

Who has it
Sysadmins and small-business owners.
What people use now
- Zylo
- Torii
- Productiv
A way through
A lightweight (not Zylo/Torii-scale) shadow SaaS discovery tool for SMBs with a single IT person, with simple alerts instead of enterprise analytics.
MVP scope
- Give sysadmins and small-business owners a way to do this in one sitting: See who signed up for which SaaS, with simple alerts, for companies with a one-person IT team.
- Persist the result and show it again after a reload.
- State the empty case when there is nothing to show yet, with one next step.
- Charge later with a B2B subscription, between $50 and $199 a month. The free path must finish the core job once.
- Ship the web app only. Leave Zylo to keep the jobs they already do well.

Questions
Is this idea already taken?
People already use Zylo, Torii, Productiv. Those options do not do the job in the solution above. The idea is free to build. Nothing here is an exclusive claim.
How hard is a first version?
Moderate. A tight MVP is about 3 weeks (3–4 weeks), assuming the regulated or partner-gated parts are stubbed. The paid prompt turns that into tasks.
Who would pay, and how?
The audience is sysadmins and small-business owners. Charge a B2B subscription, and test a price between $50 and $199 a month. Willingness to pay is one input to Hotness, not a promise that someone will buy.
Can I use the evidence?
Yes. Build the product. The thread title is a short excerpt with a link, not a quote we are putting in someone's mouth. Exact post dates and verbatim lines are added only after a manual check. Ideas are suggestions, not medical, legal, or financial advice.
