Nail Your YC Application Video With a Teleprompter

The Y Combinator application asks for a short founder video — usually around one minute of you and your co-founders talking to the camera. It feels low-stakes because it's so short, but it's often the first time the partners actually *see* you, and one minute goes by fast. A teleprompter helps you use every second well: hit your key points, stay inside the time limit, and still come across as a real person rather than someone reciting a pitch. Here's how to do it — and why a voice-following prompter like Sayscroll is suited to exactly this kind of clip.

What YC actually wants from the video

YC is clear that the video is about the founders, not a polished product demo. The partners want to get a feel for who you are, how clearly you think, and whether you can explain what you're building in plain language. That sets up a real tension: you want to be prepared and concise, but you don't want to look like you're reading a teleprompter word for word. The goal is to sound prepared *and* natural — and that's precisely the gap a good voice-following prompter closes.

Why a teleprompter helps for a one-minute clip

• Every second counts — with only ~60 seconds, rambling or losing your train of thought wastes a big chunk of the answer. A script in front of you keeps you on the most important points.
• You stay on time — knowing your words are right there means you can deliver a tight, complete answer instead of trailing off or running long.
• You look at the lens, not your notes — with the text near the camera, you keep eye contact with the partners watching instead of glancing down at a phone or a sticky note.
• Fewer retakes — fewer stumbles and restarts means you get a clean take faster, which matters when you're filming this late at night before the deadline.
• Both founders can use it — co-founders can each have their lines ready, so the hand-off between you looks smooth instead of awkward.

The catch: don't sound like you're reading

Here's where most teleprompters backfire for a founder video. Fixed-speed scrolling forces you to match the machine's pace, so you either race to keep up or wait for the text — and either way you sound stilted, which is the opposite of what YC is looking for. A voice-following teleprompter flips that: it scrolls as *you* speak and pauses when you pause, so you can slow down on the important line, add an aside, and still find your place. That's the difference between a video that sounds rehearsed and one that sounds like you.

But voice following only helps if the tracking actually holds. Plenty of apps advertise it and then drift or jump to the wrong line — and the moment the script loses your place, your eyes leave the lens to hunt for it, which is exactly the read-aloud look you're trying to avoid. Sayscroll locks onto the word you're saying and holds it there, so you can talk to the camera the way you would to a friend.

How to film your YC video with Sayscroll

1. Write for the ear, not the page. Draft your answer in short, spoken sentences — what's your company, who are the founders, what makes you the team to build it. One idea per line so it's easy to read at a glance.
2. Cut it to time. Read it out loud and trim until it comfortably fits in about a minute with room to breathe. Shorter almost always beats cramming.
3. Load it into Sayscroll in your browser — no install — on your laptop, phone, or tablet, and place the screen as close to the lens as you can.
4. Set a comfortable text size and margins so you can grab each phrase without darting your eyes, then turn on dark mode to cut on-camera glare.
5. Do a throwaway take to settle your pace and eye line, then record. Let your voice drive the scroll so you can pause, smile, and gesture naturally.
6. Review against YC's ask — did you and your co-founders come across as clear, honest, and likeable? Re-record the lines that didn't land; with voice following, another take is quick.

A few founder-video do's and don'ts

• Do keep it to the founders talking — YC has said repeatedly they're evaluating you, not a slick edit.
• Do bring a little more energy than feels natural; the camera flattens it, and enthusiasm about your idea reads well.
• Don't over-produce it. A clean, well-lit, in-focus clip from a laptop is fine — substance over gloss.
• Don't memorize so hard that you freeze. A prompter is your safety net so you can be present instead of panicking about the next line.

Beyond the application

If you get an interview, the same skills carry over — and so does the prompter, for practicing your answers and for the demo videos, pitch presentations, and investor updates that come after. Sayscroll is free to try with no account, and follows your voice across 60+ languages, so international founders can record in the language they're most comfortable in.
