How a startup demo video is made
Paste your startup URL
Drop in your landing page link. Rendrio reads your hero copy, features, screenshots, brand colors, and logo automatically.
AI writes the demo script
A 6-scene narrative is generated: hook, problem, solution, features, social proof, call to action. Edit the tone (pitch, launch, explain, hype) or accept defaults.
Preview in your browser
Watch the 30-second video preview with branded backgrounds, animated icons, and word-timed captions. Iterate unlimited times before rendering.
Render and post
Render to 1080p with AI voiceover and music. Download in 16:9, 9:16, or 1:1. Post to Product Hunt, LinkedIn, X, your website, or paid ads.

When founders use Rendrio
Product Hunt launch day
A 30-second hero video that runs auto-play on your PH listing converts 2–3× better than a static screenshot. Generate the morning of launch, swap the URL of your maker page if needed, and have three social ratios ready by noon.
YC / Techstars demo day
Demo day reels are usually a 60-hour project. Rendrio compresses the script-to-render cycle to under 5 minutes, leaving you free to rehearse the live pitch.
LinkedIn announcement post
A vertical 9:16 or square 1:1 video stops the feed scroll. Rendrio outputs both ratios from one generation — same script, same brand, optimized aspect.
Cold outbound + paid ads
Embed in cold emails as a Loom-style thumbnail link, or upload to Meta / LinkedIn ad campaigns. CTR on video creatives runs 2–4× higher than static.
Startup demo video FAQ
- How long does it take to create a startup demo video with Rendrio?
- Most startup demo videos are generated in 60–90 seconds from URL paste to preview. Pro renders with AI voiceover take 2–3 minutes. You can iterate the preview unlimited times before rendering.
- Do I need a script for my startup demo video?
- No. Rendrio writes the script automatically by analyzing your website. It follows a proven 6-scene structure used by YC demo day videos: hook, problem, solution, features, social proof, call to action. You can also customize the narrative tone.
- How much does a startup demo video cost?
- A single HD render with AI voiceover costs $9. A 5-pack with multiple aspect ratios costs $29. Compare to a traditional agency demo video ($1,000–$5,000) or a freelance video editor ($300–$800). Rendrio is one-time payment, no subscription, no recurring fees.
- What aspect ratios are available for social media?
- Rendrio exports startup demo videos in 16:9 (YouTube, Product Hunt, website hero), 9:16 (LinkedIn vertical, TikTok, Instagram Reels), and 1:1 (Twitter/X, Instagram feed, LinkedIn feed). The Pack tier includes all three ratios from a single generation.
- Can I use the demo video for Product Hunt or YC demo day?
- Yes. Rendrio videos are commercial-license-free and you own the output. Founders use them for Product Hunt launches, YC application videos, investor decks, X/Twitter launch threads, and landing page hero videos. There are no usage restrictions on rendered videos.
- Does Rendrio work for B2B SaaS demos specifically?
- Yes — B2B SaaS is the most common use case. Rendrio analyzes your landing page to extract brand colors, key features, statistics, and value propositions, then assembles them into a narrative-driven demo. It works equally well for AI tools, dev tools, fintech, marketing SaaS, and vertical SaaS.
