Should I make videos to market my startup?

Two different decisions hide in this question

"Should I do video" usually collapses two unrelated bets into one. The first is video as an asset: a specific recording that does a specific job — showing what the product does, walking a new user through setup, letting a customer say in their own words what changed for them. The second is video as a channel: publishing on a schedule to build an audience on YouTube, TikTok, Shorts or LinkedIn. One is a piece of work with a defined end. The other is a standing commitment that competes with everything else in your week.

They also pay out differently. An asset is made once and used for months in places people already are — your pricing page, your onboarding email, a reply to a prospect who asked what this actually looks like. A channel pays nothing for a long stretch and then, sometimes, pays a great deal. For a founder deciding where the next ten hours go, the asset is nearly always the better first bet, and the choice of channel should follow where your buyers already gather rather than which format you enjoy making — see how to know which marketing channel to double down on.

The videos that pay for themselves first

Roughly in order of return for an early-stage product, and none of them requires a channel to exist:

1. The 60–90 second product demo — what the thing does, shown rather than described. It belongs on the landing page and in the reply to every "what is this exactly?" A visitor who watches it decides on evidence instead of on your copy, which is the same job the rest of the page is doing: turning visitors into signups.
2. The setup walkthrough — the two minutes between signing up and the first useful result. This one shortens time to value and quietly takes load off support. Put it in the welcome email and the docs, not on a channel: see improving user onboarding.
3. The recorded customer story — a real customer describing, unscripted, what they were doing before and what changed. Harder to arrange and worth more than any testimonial you write on their behalf, because the hesitation and the specifics are what make it credible.
4. The fifteen-second feature clip — one thing working, cut straight from a screen recording. Cheap enough to make weekly, and the raw material for changelogs, launch posts and social without a production process behind it.

None of these needs a studio. A screen recorder, a microphone that is not your laptop's, and a room without an echo clear the bar for all four — the open-source Cap is one of several tools that make the recording part close to free. The expensive part was never the camera; it is deciding what the video is for.

When a channel is actually worth starting

Start one when three things are true at once. You can name the specific person watching and what they are trying to do — not "founders", but the person searching for the problem you solve at 11pm. You can hold a weekly cadence for two or three quarters without displacing work that is currently producing customers. And you can stand the format enough to keep going after the first month, when the view counts are still embarrassing. If any of the three is missing, the honest move is to borrow an audience instead: going on someone else's podcast or channel is the same medium with none of the cold start, which is the ground covered in working with creators.

First-party note from building AgentCeres — the AI Growth Officer at agentceres.com: the demonstration on our own homepage is not a video. It is a scripted chat animation rendered by the page itself, with the script sitting in a source file beside the component and a test that fails the build if the mockup ever shows something the product cannot actually do. That choice was about maintenance rather than taste. When the interface changes, editing a line of that script takes a minute; a recorded demo has to be re-recorded, re-edited and re-uploaded, so in practice it drifts and quietly starts advertising a product you no longer ship. Recordings are still the right tool for the four jobs above — but the demo people see most often is worth building in whichever medium you can keep current.
