ScreensConcept
Desktop and mobile: Presenters set up and review slides at a desk, while cohosts and attendees follow along from any device during live meetings; both flows are essential. Sample screens on a computer and a phone, in the proposed brand. Their numbers are sample data.

About this appAI proposal
Keystage sends only your slides to attendees, not your desktop. Attendees open a link in a browser and follow along. Notifications, open tabs and private files never leave your machine, and the room needs less bandwidth than a shared screen.
Several cohosts can steer the same deck. The server keeps the current slide, so everyone sees the same slide in the same order. Someone on a slow connection jumps to the live slide instead of falling behind.
It is made for presenters and cohosts who run webinars, team briefings and distributed talks beside their usual video call. It is a managed service, so you do not have to build, host and maintain your own sync tool.

- Why this name
- A key moves the slide, a stage is where the room looks. Keystage joins cueing a slide with the shared place everyone watches.
In the first version
Members say which features they would use. It tells PWAS what people want; it changes no score.
Slides only, never the desktop
Attendees receive slide content alone. Nothing else on the presenter's screen is captured or sent.

Shared control for cohosts
Invite cohosts and let any of them move the deck, or give one a lead role. No handing over a screen.
No member yet
Server-held slide state
The current slide lives on the server. A lagging attendee jumps straight to the live slide.

Follow or browse
Attendees can look back at earlier slides, then return to the live slide with one tap.

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
$190,000
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
- Shared outputs. Every session gives attendees a link that opens Keystage in their browser. Recap pages and the attendee view carry the product name, so each talk shows it to the whole audience.
- Do they become customers?
- Attendees see it but only some run their own talks. Test how many attendees click through and start a free session after joining one; exposure alone is not proof of customers.
- First customers
- Small teams of 5 to 30 who run weekly remote webinars or customer briefings, such as a software company's customer education or sales enablement lead.
- Where to reach them
- Hacker News and developer forums: Reply in threads about screen-sharing pain and offer early access to people who built their own sync tools.
- Webinar host communities: Offer to run one session free for hosts in webinar and customer success groups, and ask for feedback.
- Direct outreach on LinkedIn: Message customer education leads who post recorded webinars and offer a pilot for their next session.
- First milestone
- Five teams each run at least three live sessions with 20 or more attendees, and two of them pay for the Presenter tier.
Why people already pay for this
- VerifiedHacker News post received 27 points and 14 comments
- Public claimScreen sharing in traditional video conferencing exposes the presenter's entire desktop and consumes significant bandwidth, creating friction in remote presentations.
- Public claimMultiple presenters or cohosts need the ability to control the current slide collectively without manually handing off screen control.
- Public claimCustom-built solutions for this problem are cumbersome to maintain and host, making a managed SaaS alternative attractive.

RisksAI inference
- TechnicalConverting PowerPoint and Keynote files faithfully (fonts, animations, embedded video) is hard. Early versions may need PDF or image upload and drop animations.
- CommercialPresenters may not want a second link next to their video call. Zoom and Teams could add slide-only sharing and make this a feature.
- TechnicalKeeping hundreds of attendees in sync while several cohosts change slides at once needs tested conflict rules and load testing.
- DataCustomers upload confidential decks. Storage, access links and deletion must be handled carefully, or the privacy benefit is lost.
- CommercialEvidence is a single Hacker News post (27 points, 14 comments) and public claims. Real willingness to pay is not shown yet.
