How to start a SSH and SSL Certificate Lifecycle Manager for Small IT business: plan and growth
A small IT team wants to stop the yearly grind of renewing SSH keys and SSL certs (with lifetimes shrinking) across a mixed Linux/Windows estate.
An owner can start “SSH and SSL Certificate Lifecycle Manager for Small IT” from a complaint people already posted. The offer, in one line: Auto-rotation and one dashboard for certs and keys across mixed Linux and Windows fleets. It is for sysadmins and IT managers. Charge a B2B subscription, and test a price between $50 and $199 a month. Begin in more than one country. Buyers already talk about this in r/sysadmin. One thread gathered 54 votes and 101 replies across Sep 14, 2026 – Oct 14, 2026. Use that room to meet the first twenty buyers. Do not export it, and do not republish the posts. The idea, the evidence, and the market estimate on this page are free to read. Two paid prompts finish the job: one drafts the offer, the price, and a ninety-day calendar; the other drafts a month of conversations and proof. One credit unlocks both. A software specification is not on this site. When the company is the product itself, a single link further down opens the founder library.

How we estimated this
- Base: 1,218,000 US employer firms with 10–99 staff.
- Has the problem: 15% (assume 15% run their own servers).
- Revenue per firm: $1,200 per year ($99/mo).

TAM is customers with the problem × revenue per customer. SAM is the part a new business can reach. SOM is a cautious three-year share of SAM. The bars use a log scale. A share marked “assume” is our judgment, not a measurement.

Questions
How much money do I need to start?
Enough to talk to buyers and deliver the offer once. A service version can start with a written process and a way to take payment. A software version is a larger bet and is not required to test the price. The band to test is $50–199 a month.
How should I price it?
Test a price between $50 and $199 a month, charged as a B2B subscription. Raise it after three paid pilots, not before the first conversation.
Where do the first customers come from?
r/sysadmin is the clue. A related thread gathered 54 votes and 101 replies. Show up there, follow the room's rules, and ask for conversations. Do not scrape it.
Do I need to write code?
No. The prompts on this page draft a plan and a month of growth. Code is a later choice. The founder site linked once below is where the build document lives, if you want it.
A separate site sells the agent build document and can build the product. Open the founder version
A two-week build starts at $10,000 on that site, after a $1,000 scoping fee.
