Investor explainer videos

A 60-to-90-second silent or narrated short that translates a Series A or B pitch into a story the room can hold. Built from your existing 3D source assets where you have them, built from scratch where you don't.

Industrial, biotech, cleantech, and hardware founders share the same problem in their fundraising window: the deck slide that explains what the company actually does runs longer than the room's attention span. A short, well-paced video, silent so it plays in a deck or narrated when it stands alone, does the work the slide can't.

CCLEMANG's process visualizations for Dowon APEX, DY Engineering, and enParticle already function as de facto investor demos. We are productizing the short-video format as a standalone offer because AI-assisted motion tooling (Runway, Veo, Kling, Imagen) makes 60-to-90 second pieces economically viable at prices founders can decide on without committee.

What we ship

Three tiers, sized to whether you bring source assets and how many languages you need.

Lean: client provides source

You have CAD, a Three.js scene, or a Blender file we can re-render. We compose the video off those assets, AI handles ambient motion and transitions, you get a 30-to-60-second silent piece sized for slide-deck embedding.

Typical: 1 to 2 weeks · $2,000

Standard: 3D built from scratch

You bring reference imagery (sketches, photos, prototype shots). We build the 3D and the motion. The default offer. 60 to 90 seconds, silent by default, narrated voiceover added for $1,500.

Typical: 2 to 3 weeks · $5,000

Premium: bespoke 3D, bilingual narration

3D built from scratch. Voiceover script (we write, you sign off). AI-voice generation in two languages, usually KR + EN, sometimes KR + JP for Japanese investor meetings. 90 seconds. Three aspect ratios (16:9, 9:16, 1:1).

Typical: 3 to 4 weeks · $10,000

What's in the video

A short investor explainer earns its 60 to 90 seconds by doing three things: showing the product or process working, sized to a non-specialist audience; surfacing the metric or outcome that turns the founder's claim into something a partner can repeat to their committee; landing on the next-twelve-months proof point that justifies the round size.

We will not write the financial numbers. We will help shape the narrative arc and the visual sequence that carries the numbers.

What we won't do

• Animate humans or biology in the base scope. AI-generated motion still has uncanny-valley moments on faces and on living tissue. Founders who need human figures route to the premium tier with custom motion budget.
• Ship more than three aspect ratios. Two TikTok variants, two YouTube variants, and a Reels cut is scope creep. Three is the cap; additional ratios are $500 each.
• Replace your IR firm's deck. The video is a complement to the deck, not a substitute.
