Questions
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 royalty-free and yours to use commercially. Founders use them for Product Hunt launches, YC application videos, investor decks, X/Twitter launch threads, and landing page hero videos. Once you download a render, it is yours to keep and publish anywhere.
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.
