ScreensConcept
Desktop app: Certificate monitoring and inventory management requires reviewing dashboards, dense tables, and exports—work done at a desk by operations and infrastructure teams. Sample screens on a computer, in the proposed brand. Their numbers are sample data.

About this appAI proposal
Lapse Watch checks the SSL/TLS certificates on your sites, APIs and services and warns you well before they expire. Add a hostname, or let it find certificates for your domains from public certificate transparency logs. Alerts go to email, Slack or a webhook.
It is made for small teams with a handful to a few hundred certificates who do not want a full certificate management platform. You pay for each certificate you monitor. There is no plan to choose.
Each alert names the host, the days left and the owner. You can snooze it, hand it to someone else, or mark it renewed and Lapse Watch re-checks the live certificate to confirm.

- Why this name
- A lapse is what a certificate does when it runs out. Watch says the job: keep an eye on it so you do not have to.
In the first version
Members say which features they would use. It tells PWAS what people want; it changes no score.
Expiry alerts on your schedule
Set warning points such as 30, 14, 7 and 1 days. Alerts repeat until the live certificate is renewed.

Email, Slack and webhooks
Send each alert to one or more channels. Route by team or domain so the right person sees it.

Find certificates from public logs
Enter a domain and see certificates issued for it and its subdomains, so forgotten hosts are not missed.

Renewal check
After you renew, Lapse Watch re-checks the live endpoint and closes the alert only when the new certificate is served.

What it could be worthEstimate
What a software business making this much sells for today, from real deals. Pick a monthly revenue.
If it makes
Worth about
$194,000
Sale range $132,000 to $263,000
$120,000 a year in revenue
From 87 software businesses listed and sold on Empire Flippers in the last year, revenue vetted by the broker: they sell for about 19× their monthly revenue, most between 13× and 26×.
Measured on profit, the middle deal is 32× monthly net profit: about 2.7 years of profit.
An estimate, not an offer or financial advice. A real price depends on profit, growth, churn, how much of the work is the owner's, and the buyer.
How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- Partners and integrations. Listed in Slack and in developer tool directories; alerts posted in team channels show the product name to colleagues who can then add their own certificates.
- Do they become customers?
- Colleagues seeing alerts in Slack could become buyers, but most only read them. Test how many channel members open an account within 30 days.
- First customers
- Small software agencies and startups with 10 to 200 certificates, where one engineer or ops lead handles renewals.
- Where to reach them
- Hacker News and dev forums: Post a Show page and a short write-up on certificate outages, linking to a free three-certificate check.
- Agency owner communities: Offer a free audit of a client portfolio's certificates and show which ones expire soon.
- First milestone
- Ten paying teams monitoring at least 10 certificates each within 60 days of launch.
Why people already pay for this
- Public claimOrganizations need alerts before SSL certificates expire to prevent service outages
- Public claimSimple, affordable pay-as-you-go pricing is preferred over complex plans
- Public claimThere is demand for multi-channel alert delivery

RisksAI inference
- CommercialA newly launched competitor already offers pay-as-you-go expiry alerts; differentiation on price and renewal confirmation must be proven.
- TechnicalHosts behind firewalls or private networks cannot be probed from the public internet, limiting coverage of internal certificates.
- DataTransparency log data is large and noisy; discovery may list hosts that customers do not own or want watched.
- CommercialLow per-certificate pricing may make revenue small unless customers hold many certificates.
