Work

Real projects, real challenges, real results. Here's how we help Bitcoin companies ship great video.

[What We Create]

Videos we create

Product Announcement Videos

Focused on making new product features exciting and highly shareable on socials.

Examples: BitChat Launch, STRIKE Widget, BITGO Crypto for Banks, History of Bitcoin Book

Product Explainer Videos

Showing how a product feature works and how to set it up.

Examples: STRIKE x Bitkey Withdrawal, CASA Recurring Buys, STRIKE x Bitkey Buy, STRIKE Billpay

Educational Explainer Videos

Build deeper understanding around Bitcoin - for internal or external audiences.

Examples: Real Estate vs Bitcoin, Bitcoin's Scarcity, What is Money, Buying the Dip

Product Announcement Videos

No marketing team or brand guidelines

Model and create video from early screenshots and focus on the music

Product Explainer Videos

Strike x Bitkey

Challenge:

7-day deadline, no 3D model for Bitkey, minimal brief

Goals:

Educational Explainer Videos

vs Bitcoin

Challenge:

React to real estate trend on social media, no possibility for Jack to record a voiceover

Solutions:

Cut multiple podcast appearances together and create a 2D animation narrative

Outcome:

Full on animation viral on the socials

[Client Spotlight]

STRIKE

Case Study

Strike doesn't have a marketing team and outsourced their video creation to us. We're in close contact with their Product Marketing Manager who briefs us about the timelines when new features are shipped and provides us with Figma wireframes and a quick brief on what the new feature is about. We then handle all the creative processes internally and have regular feedback loops with the PMM.
