How Startups Use Demo Videos for Growth and Fundraising

What’s interesting is that many accelerator programs now ask startups to submit a demo pitch video as part of the application or presentation process. And it makes sense. A written application can explain the idea, but video can show the product, the team’s energy, and the story behind the company much faster.

The challenge is that early-stage teams are often working with tight deadlines and limited budgets. Because of that, it is not rare to see demo or pitch videos with some level of AI involvement, from AI-assisted scripting and visuals to voiceovers, editing support, or quick concept development.

We’ve worked with a lot of companies that went through accelerator programs or used demo and pitch videos for fundraising, including quite a few YC-backed companies. You can also check out our YC companies case study to see how we’ve worked with them and the kind of creative support we’ve provided.

We also analyzed 24 YC pitch and demo videos from the 2025 batches, looking at how startups are using AI, where it helps, and where it can start getting in the way of the product story.

So, in this guide, we’ll break down what these videos are, how startups use them, what we believe makes AI genuinely useful in a pitch or demo video, and the 2026 trends shaping how founders present their products to investors, accelerators, and early customers.

So, let’s talk about it:

What is pitch/demo video for startups

Before we dive in, it is worth clearing something up.

Pitch videos and demo videos often get talked about like they are the same thing, especially in the startup world. But they are not quite the same.

• A pitch video sells the opportunity.
• A demo video shows the product.

A pitch video helps people understand the bigger story: the problem, the market, the business, and why the company is worth paying attention to. A demo video is more product-focused. It shows how the platform works, what the user experience looks like, and how the product solves the problem in real life.

In many cases, a startup will need both. One video for investors and accelerator applications. Another for sales, onboarding, product education, or the website.

But early-stage teams do not always have the time, budget, or bandwidth to create two separate videos. That is why a lot of startups now combine the pitch video and demo video into one stronger asset.

And honestly, it makes sense.

For accelerator programs like Y Combinator, Techstars, and Google for Startups Accelerator, founders are often expected to present the company and show the product within a very short window. Demo Day presentations usually need to explain the opportunity, prove there is a real problem, show the product, and make the audience believe in the company’s potential.

So, for the purpose of this blog, we will use demo video and pitch video interchangeably. While they are technically different, startup videos for accelerator programs often need to do both: pitch the opportunity and show the product clearly in action.

How startup use their pitch/demo video

We have already mentioned that in accelerator programs, pitch and demo videos are often used as part of the final presentation. This is usually where founders get the chance to present their company in front of VCs, angel investors, mentors, and potential partners.

If you’re in the tech industry, you’ve probably heard of YC or other startup accelerator programs. For many founders, getting into these programs is a major early milestone because it can open doors to funding, mentorship, investor networks, and faster growth.

But the purpose of the video does not stop there.

A lot of startups repurpose these videos long after the accelerator program ends. The same core video can be cut into shorter social clips, adapted for landing pages, used in investor follow-ups, added to sales decks, or turned into paid marketing assets.

And because these videos are usually packed with information, many companies also create shorter versions that focus on one specific message. For example, one cut might explain the problem, another might focus on the product demo, while another could highlight traction, customer pain points, or the founding team.

We did something similar with our client Tasker, although the style was slightly different. Their main video was more UGC-inspired, built around a talking-head format where the founder explained what was happening and guided the viewer through the story.

From there, we created shorter versions that focused on specific messages or features, making the content easier to reuse across different channels and campaign moments without needing to create a completely new video every time. In Tasknet’s case, we were able to keep the same core script and visuals, then adapt the edits around different focal points, turning the main video into a flexible asset that could be repurposed into more targeted content.

Some startups even create different versions for different markets, including translated voiceovers, localized subtitles, or language-specific edits. This makes the video more flexible and helps the team get more value from one production.

That is why a good pitch or demo video should not only work for one presentation. It should be built as a reusable asset that can support fundraising, sales, marketing, and product education beyond Demo Day.

How we analyzed 24 YC pitch and demo videos

We did not want to rank the videos based on which one looked coolest, so we built a simple 1–100 scoring system around four things:

• Product understanding
  • How quickly does the video help you understand what the product does, who it is for, and why it matters?
  • High score: the product clicks quickly.
  • Low score: you are still trying to work out what is being sold halfway through.
• Hook strength
  • How well do the first few seconds earn your attention?
  • High score: there is an immediate reason to keep watching.
  • Low score: the video takes too long to get going.
• AI seamlessness
  • Does the AI-generated content actually feel like part of the video?
  • High score: polished, consistent, and easy to forget AI was involved.
  • Low score: artifacts, strange motion, or awkward transitions start stealing attention from the product.
• AI intentionality
  • Is AI there because it makes the idea better, or just because it can be?
  • High score: it helps explain the product, strengthens the story, or creates something genuinely useful.
  • Low score: it feels bolted on and ends up doing more distracting than explaining.

We then asked selected senior members of the Motion team to score each video using the same framework. They regularly work with YC-backed startups and early-stage tech companies, so they were looking at more than whether the animation was nice. The bigger question was whether the video was actually doing its job.

Each reviewer added notes behind their scores. We used Claude afterwards to help organise the results and pull out recurring patterns, but the scores and creative judgement came from our team.

We are also working on a separate article where we will get properly nerdy about the ranking: who scored highest, where each video won or lost points, and what our scoring system picked up across the full list.

This article is less about who came first. We are more interested in what the videos tell us about how startups are using demo videos right now: what they are trying to explain, where video fits into the launch or sales process, and why some products need a demo video in the first place.

What did we learn?

Clarity mattered more than flashy AI

• Clear product story came first.
• Strong scripts could carry videos even when the AI was not perfect.
• Polished AI could not fix a confusing explanation.

AI worked better when it had a specific job

• The strongest examples used AI for a clear reason.
• It worked well for supporting concepts, creating difficult visuals, or making the story more engaging.
• When AI became the main attraction, it could distract from the product.

AI-generated people showed problems more easily

• Lip-sync, facial movement, and character consistency were common weak points.
• These issues made some videos feel obviously AI-generated.
• The more human the moment, the more noticeable those imperfections became.

Motion design made AI easier to follow

• Motion graphics, typography, UI animation, and overlays helped guide attention.
• These elements made the story easier to understand.
• AI created the visual, while motion design helped give it structure.

A strong hook still needed a payoff

• Humor, unusual visuals, and strong opening lines helped grab attention.
• But the better videos also explained the product clearly afterwards.
• Getting attention is only useful if the viewer still understands the product.

Founder perspective: how startups actually use demo videos

To better understand what founders need from their demo videos, we reached out to several founders and growth teams about their experience introducing a product to a wider audience. One of the people we spoke to was Shardul Mane from Supermemory AI. Their program was slightly different from traditional accelerators because they did not have a formal “Demo Day,” but their pitch and demo videos still played an important role in product awareness and growth.

We discussed three videos shared on their LinkedIn. The first two were created around the launch of specific features, so they needed a more focused treatment: explain the feature, show why it mattered, and make it easy for the right audience to understand quickly. These were closer to pitch/demo launch videos, created before the company had raised capital, with the main goal of supporting the launch and demonstrating the product clearly.

Those first two videos were produced by freelancers, but the team still had to provide the concept, script, product materials, assets, and direction. The third video was different. It was created fully in-house and worked more as a content piece for distribution and product awareness, with the founder and team becoming a bigger part of the story rather than directly selling a specific feature.

“For a community-centric startup, raw authenticity beats packaged hype every time. We learned that our audience connects far more with a founder genuinely explaining a problem and showing the raw UI solution than they do with a slick product video.”
— Shardul Mane, Co-Founder @ Supermemory AI

That quote sums up one of the biggest takeaways from the conversation. For Supermemory AI, the goal was not always to create the most polished product video. It was about choosing the right format for the moment, whether that meant working with freelancers, producing content in-house, or getting external creative support based on the video’s purpose, timeline, and production needs.

Our perspective on pitch/demo videos

While working on this blog, we ended up speaking with a few senior and lead members of our team about what actually makes a good pitch or demo video, especially for startups in the middle of an accelerator program or preparing for fundraising.

One thing we understand is that, as an extension of these companies’ teams, we have a “responsibility” to help them communicate what they are trying to say in a way that is engaging but also easy to digest. This is especially important for a lot of startups that are part of the SaaS and tech industry, as their products tend to be very specific and intricate.

For SaaS or tech products, there usually needs to be an extra level of understanding around composition. A lot of people focus too much on design aesthetics and sometimes miss the fact that SaaS or tech products often need to show a lot of information in a single frame.— Waladun Sabiq, Senior 3D Animator, Motion The Agency.

That is also something we heard when talking to founders. Almost all of them said that if they were to focus more on one thing, it would be the narrative and how the product solves a real pain point, not just showcasing how the product works. A few of them learned that the hard way.

So, if we can suggest anything in this blog, it is to always start with ideation and preparation. For clients with products that are difficult to understand, we almost always ask how the product works, what features they want to highlight, and what message they want the audience to take away.

Another thing is that for something this important, always start with storyboarding. It helps make sure all the information is clear before moving into production. We actually talked about the importance of storyboards in our blog, “How Storyboards Improve Explainer Videos.”

Conclusion

After looking at how startups use pitch and demo videos, and reviewing 24 YC examples, one thing stood out: AI did not make the strongest videos good. Clear storytelling did. The best videos were the ones that made the problem easy to understand, showed the opportunity clearly, and helped viewers quickly see why the product mattered.

That is why a good pitch or demo video needs to do more than simply show the product. For startups going through YC, accelerator programs, or fundraising, it needs to explain the problem, show the product in action, and give investors or early customers a clear reason to care. AI can help with that, but it works best when it has a specific job, whether that is creating a visual, supporting a concept, or adding something that would otherwise be difficult to produce. When AI becomes the main attraction, it can start pulling attention away from the product itself.

The strongest videos we reviewed were built around a clear narrative rather than a feature walkthrough. The product was easy to understand, the pain point was obvious, and the visuals helped guide the viewer instead of making the video feel busy or overcomplicated.

That is also why preparation and storyboarding matter so much, especially for SaaS and tech products. A polished video is great, but clarity is what makes people care. The best videos start with a strong structure, a focused message, and a clear understanding of what the audience needs to take away.
