Kite Makes a Startup's Demo Look Like an Apple Ad

Two people, a browser tab, and a bet that most founders have a great product and a demo video that undersells it. Kite records your screen and does the cinematic part for you.

There is a specific kind of pain every software founder knows. The product works. The launch date is set. And the demo video - the thing that will greet everyone who lands on the homepage - looks like it was recorded in one take at 1 a.m., cursor drifting, no zoom, a little too long. Kite, a two-person company from Y Combinator's Summer 2023 batch, was built to close exactly that gap between what founders can build and what they can show.

Kite is a screen recorder, but that description undersells the part that matters. Plenty of tools can capture your screen. Kite's work starts the moment you stop recording. It watches where your cursor moves and where you type, then automatically zooms and pans to follow the action, so the camera always seems to know where to look. It can drop your app onto a rotating 3D MacBook or iPhone. It can add animated text scenes timed to music, narrate the whole thing with an AI voice, and hand you a file that looks less like a screen capture and more like a product commercial.

The founders are Derek Feehrer, the CEO, and Todd Ashley, the CTO. That is the entire company. Two people serve, by their own account, hundreds of YC startups who use Kite for launch videos, social clips, landing-page demos and feature announcements.

The chore everybody shares

Most successful founder tools come from someone building the thing they personally kept needing. Kite fits that pattern. Before it, Feehrer shipped a run of small software products - MockRocket, Appointment Scanner, DashDisplay - the kind of indie tools you make when you are trying to find the one that sticks. He has been open about how unglamorous the start was.

"It's been 3 years since I quit my job and just started building the software tools I wanted in the world. With $60 in revenue at the time of quitting..."Derek Feehrer, Co-founder & CEO

Sixty dollars. Not sixty thousand. The number is worth sitting with, because it reframes what the beginning of a company actually looks like. Three years and several products later, that path led to Kite and a spot in Y Combinator, with Tom Blomfield as the partner and, soon after, a $500,000 seed round on top of earlier funding for $630,000 total.

What Kite noticed is that making a marketing video is a chore almost everyone in software shares and almost no one enjoys. It is not a niche annoyance. Every launch wants a video. Most people either skip it, ship something rough, or lose two days to a timeline editor. Kite turned that shared friction into a product.

From record button to finished cut

The workflow is deliberately short. You are not learning video editing. You are recording, then getting out of the way while the software does the tedious parts.

03

04

AI narration and a royalty-free track.
05
Export
A shareable, polished clip.

Reviewers who have timed it report making a finished mockup video in roughly fifteen minutes. That number is the whole pitch. The 3D frames are rendered live in the browser with WebGL, which is why you can spin your app onto a MacBook without exporting to a heavier desktop program. The voiceovers lean on text-to-speech models with a choice of voices - the kind of feature that sounds like a gimmick until it is 11 p.m. before a launch and you need narration you do not have to record yourself.

Who is actually using it

The clearest signal of Kite's fit is who reaches for it: other startups. YC companies are both the founders' peer group and a natural first market - people shipping fast, launching often, and short on the time or budget to hire a motion designer. Beyond that circle, the users are solo makers and small marketing teams who need a video to look credible without a production line behind it.

Your startup is two people. Your launch video does not have to look like it.

That is the emotional core of the product. A small team is judged, often unfairly, on the polish of its first impression. Kite lets a company present at a scale it has not reached yet, without pretending to be something it is not.

Where it sits in a crowded room

Screen recording looks like a packed category - Loom, Screen Studio, CleanShot X, Descript, Tella and others all live there. But the category splits once you ask what a recording is for. Loom is built for quick, disposable messages you send and forget. Kite is built for the opposite: a recording you want the whole internet to watch. Its wedge is not capture, it is everything that happens after you press stop.

Directional comparison based on published user reviews, not a controlled benchmark.

Kite runs on a freemium model, and reviewers note the free tier is genuinely usable rather than a locked demo. Paid subscription plans open up heavier usage, advanced features and branding. It is a familiar structure for developer and founder tools: let people feel the value on a real project, then charge the ones who come back.

The market underneath

Zoom out and the opportunity is large and unusually manual. Video marketing is estimated at around $104 billion, and a great deal of that spend still flows to agencies, freelancers and editors doing work by hand. When a market is that big and still that manual, software is usually not absent - it is early. Kite's bet is that a meaningful slice of that budget belongs to a tool rather than a team, especially at the small-company end where the budget for an agency simply does not exist.

The expertise on display is narrow and deep, which for a two-person company is the point. This is a team that has built demo and mockup tools before, that understands the specific frustration of showing software well, and that has chosen to do one job - turn a recording into something worth sharing - rather than sprawl into a general video suite. The discipline shows in the workflow: five steps, no timeline to master.

Whether Kite grows into the default video layer for startup launches or stays a sharp tool loved by a specific crowd, its wager is clear and easy to understand. Founders will keep shipping products faster than they can present them. Something has to make the presentation catch up. Kite is trying to be that something, two people and a browser tab at a time.
