Startup Video Stack

AI Video Generator for Startups

Pitch decks, investor updates, launch trailers, onboarding clips, hiring videos, every video format your startup ships, generated from a prompt. One tool, the entire startup video stack.

An AI video generator for startups produces the entire video stack a startup needs, pitch deck videos, investor update videos, launch trailers, customer onboarding clips, and hiring/recruiting videos, all from a single text prompt. Motionfly is purpose-built for early-stage and growth-stage startups: the same prompt-to-video engine handles every video format a founder needs, without booking a freelancer per asset and without hiring an in-house design team.

AI video generator for startups, the full startup video stack

Startups ship 10x more video content than their team can produce

Founders today are expected to produce video for fundraising decks, investor updates, launch days, customer onboarding, hiring posts, and weekly all-hands recaps. Each video traditionally requires either a freelance editor at $500-$5K per cut or learning After Effects, neither of which scales for a five-person startup. The result: most early-stage startups skip video entirely, losing the investor-attention and customer-conversion lift it provides.

✕Founder bandwidth is the scarcest resource at an early-stage startup
✕Each video traditionally requires a freelancer ($500-$5K) or an in-house design hire
✕Pitch deck slide 3 is usually a flat screenshot when it should be a hero shot
✕Investor updates are text-only when video drives meaningfully higher read-through
✕Hiring posts lose to top YC-backed startups that produce video creative in-house
✕Customer onboarding is a stack of Looms when it should be a polished branded demo

One prompt-to-video engine, every video format your startup needs

Motionfly is built around the assumption that a startup needs many short videos, not one big one. The same prompt engine, the same 3D mockup library, and the same brand-palette system produce every format: a 30-second pitch hero shot for slide 3, a 90-second monthly investor update, a 60-second launch trailer, a 45-second customer onboarding clip, and a 30-second hiring video. One prompt vocabulary across the whole stack, so the brand stays coherent and the founder stays in the air.

Pitch Deck Hero Shots

30-60 second videos optimized for slide 3 of a pitch deck: 3D MacBook + iPhone hero shot of your product, animated UI callouts on the most impressive feature, palette matched to the deck.

Investor Update Videos

60-90 second videos for your monthly or quarterly investor email. Founder-tone voiceover, customer logo animations, metric overlays, milestone reveals, all from the recap text you'd write anyway.

Launch Trailers and PH Cuts

Cinematic launch creative for Product Hunt, X, LinkedIn, and your landing page. Same engine that powers our use-case launch pages, here positioned as part of the startup video stack.

Customer Onboarding Videos

Polished 45-second feature walkthroughs for in-app onboarding, customer success emails, and your knowledge base. Branded, consistent, and faster to ship than a Loom you'd then have to re-record.

Recruiting and Culture Videos

30-60 second hiring videos that compete with the production polish top-tier startups bring to the talent market, no agency, no in-house videographer, just a prompt.

Brand-Coherent Across Formats

One brand prompt (palette, fonts, tone, devices) carries across every video format. Investor updates, hiring posts, launch trailers, and onboarding clips all look like they came from the same studio, because they did.

How it works

Describe your startup, the format, and the audience

Write a short prompt: what your startup does, the video format you need (pitch hero, investor update, launch, onboarding, hiring), the audience, and the tone. Motionfly handles the rest.

Pick the device, the length, and the brand prompt

Choose the 3D device (MacBook, iPhone, iPad, Apple Watch), the target length, and your brand prompt (palette, fonts, voiceover tone). The brand prompt is reusable across every subsequent video.

Render and ship across every distribution channel

Embed in your pitch deck, drop in your investor email, post on Product Hunt, send to your customer success queue, attach to your hiring post. One render, every channel.

Who is the AI video generator for startups for?

Motionfly is the video stack for the modern startup, every format a founder needs, in one prompt-to-video engine, without booking a freelancer per asset.

Pre-seed and seed founders
You need a pitch deck hero shot, a launch video, and a customer onboarding clip, all on a runway that doesn't include a design hire. Motionfly compresses what used to be three separate freelance engagements into one tool a founder operates between meetings.
Series A and B growth-stage startups
Marketing has the budget for a videographer, but the videographer is the bottleneck on every launch. Motionfly takes the long-tail of videos (per-feature demos, investor updates, hiring posts) off the videographer's plate so they can focus on hero pieces.
Solo founders and indie makers building in public
Building in public means shipping launch creative every quarter and hiring updates every month. Motionfly lets you ship that cadence without an editor on retainer, so the build-in-public motion compounds instead of stalling on creative bandwidth.
Heads of growth, marketing, and people operations
You're the operator inside the startup who actually has to ship the videos. Motionfly is the unblock: pitch decks for the CEO, investor updates for finance, hiring posts for People Ops, all from one tool with one brand prompt.

A real startup investor update prompt, and what Motionfly generates

Describe the startup, the milestone, and the audience. Motionfly turns the recap you'd write anyway into a polished video update.

Prompt

Investor update video for Apex AI, a YC W26 batch company building developer tools for AI agents. We just shipped our v2 release with multi-agent orchestration and added 5 new enterprise customers (Stripe, Vercel, Linear, Plaid, Brex). Audience: our 12 angel investors and our 2 institutional VCs. Tone: confident, founder-narrated, data-forward. 90 seconds. Brand: white background, deep blue accents, monospace headlines. Include a 3D MacBook of the dashboard and a callout for each enterprise logo.

What Motionfly generates

Motionfly generates a 90-second investor update video opening with 'Apex AI, November Update' in monospace headlines on a white background. The camera cuts to a 3D MacBook mockup of the Apex AI dashboard, walking through the new multi-agent orchestration feature with animated callouts. A second segment shows the 5 new enterprise customer logos animating in (Stripe, Vercel, Linear, Plaid, Brex) with a brief metric overlay for each. AI voiceover narrates in a confident founder-tone with data points front and center. Closes with 'Onward' in monospace plus the next milestone preview. Exports as 16:9 for the investor email body, 9:16 for LinkedIn investor-targeted promo, and 1:1 for the team Slack channel.

Frequently asked questions

What types of videos do startups actually need?

At minimum: a pitch deck slide-3 hero shot, a launch trailer, and customer onboarding clips. Series A and beyond add: monthly or quarterly investor updates, hiring/culture videos, all-hands recap videos, and per-feature demo videos. Motionfly handles all of these with a single prompt-to-video engine, so the same brand identity carries across every format and the founder doesn't need a different tool per use case.

Can I produce a pitch deck hero shot specifically?

Yes. Pitch deck videos are typically 30-60 seconds, embedded into slide 3 as a screen recording or video link. Motionfly produces them with a 3D MacBook plus iPhone hero shot of your product, animated UI callouts on the most impressive feature, and a brand-coherent palette that matches the rest of the deck. Investors who watch a slide-3 video stay on the deck longer than investors who only see screenshots.

Are these videos polished enough to send to YC, A16Z, or other top-tier VCs?

Yes for most use cases (investor updates, launch trailers, demo clips). Top-tier VCs see hundreds of pitches and reward production polish; Motionfly's 3D mockup engine produces output that's indistinguishable from agency work to most viewers. For your single defining hero pitch video that you'll show in a partner meeting, a human production crew is still preferable. For everything else (the long tail of monthly updates, demo clips, and launch creative), Motionfly is the right tool.

Does Motionfly support investor update videos at scale (monthly or quarterly cadence)?

Yes, this is one of the most common use cases. Founders write a brief monthly recap (revenue, customer wins, product shipping, team changes), Motionfly generates a 60-90 second video version with brand-coherent visuals, and the founder embeds it in the investor email or LinkedIn post. The cadence can be monthly or quarterly. Each subsequent video reuses the brand prompt, so the work is just writing the recap.
