Pre-flight check for conference presenters

Presenters only discover that screen sharing is broken, audio is muted, or lag is unbearable when they are already live in front of an audience. Complaints describe this exact scenario: 'screen sharing sometimes share a different window than intended,' 'crashes when sharing full screen mode,' 'the screen share does not work properly and we have to wait for it to start sharing,' and 'the app dashboard is not user-friendly and screen freezes when using screen share.' The discovery moment is the worst possible one — mid-meeting, with attendees watching.

Conferencing vendors have no incentive to build a thorough pre-session diagnostic because their product is the meeting itself, not the preparation for it. A meaningful pre-flight check would surface problems the vendor's own stack causes, which is an uncomfortable feature to ship. The buyer who cares most — a conference organizer or AV team at an event company — is different from the user (the speaker), so pain reports don't consolidate into a clear product request the vendor acts on.

What's missing is something that runs before the meeting opens and checks not just internet speed but the full chain: which audio output device is active, whether system audio routing is working, whether the intended window is actually the one that will be shared, and whether the frame rate degrades past a threshold when scrolling or playing video. No existing conferencing tool checks all of these together before the session starts. The few that do a 'test call' only check microphone and camera — they don't simulate screen share load.

For event companies and webinar producers who run paid events, a presenter failure isn't just embarrassing — it's a refund request. The need recurs every event, every week.

What to build

Build a standalone pre-session diagnostic app that a presenter runs 10 minutes before any video call — it checks active audio output routing, simulates a screen capture of the intended window at target frame rate, plays a short system audio sample and confirms it would be captured, and produces a one-page report the presenter can share with their AV contact if something is wrong.

Where to start

Sell first to webinar production agencies that manage multiple clients' virtual events — they have the most to lose from presenter failures and already charge a service fee that absorbs a tool cost, so the sale doesn't require a new budget line.

The hard part

Simulating screen share load without actually being inside a live conferencing session is technically indirect — you're inferring what will happen rather than measuring it — so false positives (telling someone there's a problem when there isn't) will erode trust fast and you'll need to be very conservative in early versions.

How it makes money

Monthly subscription per producer seat, with a free tier that covers one pre-flight check per week to drive word-of-mouth from individual speakers who discover it through an agency.
