AI Video for Startups: Explainers, Launch Clips and Demo Videos
TL;DR: Startups need more video than they can afford traditionally, and AI production changes the arithmetic without lowering the standard. Commission in this order: homepage explainer first, launch teasers second, demo cuts third, recruiting piece fourth — the explainer defines the visual system everything else inherits.
What startups actually buy
Four formats recur. A 60–90 second product explainer for the homepage, the highest-leverage video a startup owns because it sits at the top of every funnel built afterwards. Launch and feature teasers of 15–30 seconds, needed several times a quarter, which is precisely why each one should not cost a shoot day. Demo and walkthrough cuts for sales and onboarding, aimed at someone who already said yes. And a recruiting piece covering what the team is building and how it works — often the hardest to staff, because the people in it are the people who are busy.
Notice what is missing: anything requiring your real team on camera. That is deliberate, and it is the next section.
Fictional characters only - what that means for a startup
CarlosVideo18+ produces fictional characters only, never real people. For a startup the constraint is easier to live with than it sounds, because almost every startup video is about a product rather than a person. Explainers, teasers and demo cuts need no faces at all; where a human figure helps, they are an anonymous generated stand-in — no release forms, no scheduling across three time zones, and no one to coordinate when the person leaves in month four and the video is still converting.
The limit is real-person endorsement: a generated double of your actual founder is off the table by design. The working substitute, used by most clients, is scripted voice-over carrying the founder's words and name over product footage. A second advantage is consistency — one character built once can appear in the explainer, the teaser and the recruiting cut, which is what "brand" usually means in practice. Attributes are locked across a project as described in the character consistency guide.
The order to commission in, and how to brief it
Most startups order backwards: the flashy launch video first, the explainer never. The sequence that compounds is explainer (it defines palette, pace, type and tone), then teasers (now cheap, because the system exists), then demo cuts, then the recruiting piece. The first project matters more than its budget, because every later asset is a variation rather than a new decision.
Briefing for a startup audience fails on three things: too much product, no narrative spine, and no decision about who is watching. Fix all three with one sentence of purpose, a problem → mechanism → outcome spine, fixed character attributes written once, and must-not-haves covering unverifiable claims, competitor references and unsourced statistics. The full template is in How to Write an AI Video Brief; review the first cut against the criteria in How to Judge AI Video Quality.

Frequently asked questions
Is AI video good enough for a funded startup's homepage?
For explainers, launch clips and demo cuts, yes — provided the brief is specific and the claims are yours to make. The failure mode is an under-specified brief producing a generic result, so review the first cut against a written checklist.
Can the video feature our real founder or team?
No. Production uses fictional characters only, never real people. The standard substitute is scripted voice-over carrying the founder's words over product footage, which keeps the message personal without a likeness.
How much does a startup explainer cost?
CarlosVideo18+ prices flat at $94 to $250 per video, revisions included, with 7-day standard delivery. Batches of launch teasers are quoted as a package so a quarter of release content can be budgeted in advance.
How fast can you turn a video around for launch day?
7-day standard delivery, or 24–48 hour rush when the deadline is confirmed before kickoff. The variable on the client side is how quickly notes arrive after the first cut.
Can one character appear across several videos?
Yes, and it is worth doing. Attributes are fixed once and reused across the explainer, teasers and recruiting piece, which is what makes separate deliverables read as one brand.
What do you need from us to start?
A short brief, brand colours and fonts, UI screenshots or product footage, and any claims that may appear on screen with their source. Everything else the studio derives.
