Sprint Estimate Reality Check is a startup idea for engineering managers and scrum masters. A team finished PI planning with low confidence: story points were arbitrary because leadership 'vibe-planned' priorities without historical velocity. A thread in r/devops drew 61 upvotes and 47 comments between Sep 14, 2026 – Oct 14, 2026. People get by with Jira reports and LinearB, and that still leaves this job open. Hotness is 2.75, Simmering. Mild annoyance. Some willingness to pay. The thread drew 61 upvotes and 47 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
Engineering managers and scrum masters.
What people use now
- Jira reports
- LinearB
A way through
A tool that checks new sprint estimates against historical velocity and similar past tickets and flags estimates disconnected from real data.
MVP scope
- Give engineering managers and scrum masters a way to do this in one sitting: Flag new story-point estimates that statistically drift from your team's historical velocity before the sprint starts.
- 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 Jira reports to keep the jobs they already do well.

Questions
Is this idea already taken?
People already use Jira reports, LinearB. 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 engineering managers and scrum masters. 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.
