Demo videos for startups, without a video team

At a startup, the person who should make the demo is also shipping the product, answering support, and writing the deck. There is no video team, and there is rarely time to learn one. RunDemo removes the whole production step: paste your product URL, describe the flow, pick a voice, and an AI agent opens your product in a browser, performs the walkthrough, and lays a synchronized voiceover over it.

What comes back is a shareable narrated MP4 of the actual product, not a mockup and not a screen recording you had to sit through recording. That means the founder who knows the product best can make the demo in the time it used to take to schedule one.

A launch demo you can finish today

Launches live and die on timing. The moment you ship, you want a demo for Product Hunt, X, the launch email, and the press kit, and you want it before the momentum fades. RunDemo turns that into an afternoon task instead of a week of coordination. Describe the flow you want to show, generate it, watch it back, tighten the script, and re-render. Because editing means editing the transcript rather than re-recording, you can iterate on the narration until the hook lands without ever opening a video editor.

Fundraising demos that show, not tell

Investors sit through a lot of slides and very few working products. A crisp 60-second narrated walkthrough of the real thing does more for a raise than another feature bullet, and it travels: you can drop it in the deck, attach it to the follow-up email, and send it to a partner who missed the meeting. With RunDemo you can keep that demo current as the product evolves through the raise, regenerating it when you ship something worth showing, so the version in an investor's inbox is never three weeks behind the product.

Landing pages that convert cold traffic

A landing page with a narrated demo tells a visitor what your product does faster than any headline. The problem for early teams is that the page changes weekly while the demo you recorded once does not. RunDemo keeps the two in sync: when you reposition, rename a feature, or redesign the app, you regenerate the demo instead of booking another recording session. You can make several variants, one per audience or campaign, as easily as writing several prompts, and test which walkthrough converts.

Cheap to start, cheap to keep

RunDemo is free to start, so you can ship your first launch demo before you spend anything. As you grow into more surfaces, Pro is $29/mo for 30 demos and Scale is $99/mo for 150, which is far below the cost of a single freelance video and lets you treat demos as something you make often rather than once. For an early team, the real unlock is not the price, it is that making a demo stops being a project you dread and becomes a task you knock out.
