Case Study: EasySlice

How an 18-year-old solo founder built a $40k/month AI clipping business powered by Mosaic — from idea to 75,000 signups in 4 months.

Meet Søren Skarsgard, Founder of EasySlice

Søren Skarsgard is an 18-year-old college student and solo founder building EasySlice, an autonomous AI clipping + auto-posting engine for creators.

Despite his age and constraints, he's driven by a simple insight: creators want to clip + post daily, without doing manual editing or scheduling. His execution has been remarkable — EasySlice turned into a fast-growing product with real users and revenue.

"I reached out to Mosaic, OpusClip, Klap, and more. Mosaic was the only one that responded positively. I hopped on a call with Adish, shared the idea, and that's when I knew I found my backend." — Søren Skarsgard, Founder of EasySlice

The Goal

Build a fully automated service that:

1. Detects new uploads from creators
2. Clips them automatically with AI
3. Instantly posts them across social platforms

Søren's core question:

"Why do auto-posters exist and AI clippers exist, but no one does both?"

Before Mosaic

Søren tried to find existing clipping companies that could support:

• Automated ingestion of raw content
• Bulk clip extraction
• Consistency in clip quality
• Export-ready outputs for multiple platforms
• API-level reliability

What he found instead:

• Companies that only clipped content (no posting)
• Companies that only auto-posted content (no clipping)
• Slow or no response from potential partners
• No backend strong enough for his product vision

He was looking for an engine, not just a tool.

After Mosaic

Once Søren connected with Mosaic, everything clicked:

• Mosaic became the backend clip engine
• Søren handled platform logic + distribution
• Creators got a fully autonomous workflow

The impact speaks for itself:

• 5M monthly views during early growth
• 5,400-person waitlist before launch
• Launched Sep 1, 2025

By December:

• 75,000 email signups
• 2,000+ paid lifetime users
• $40k+ monthly revenue
• Tens of thousands of clips generated
• All powered by Mosaic

This validated his thesis: if you remove the editing bottleneck, creators will post more, and grow more.

The Mosaic Capabilities EasySlice Uses

To power the backend, EasySlice relies on:

• YouTube Triggers — Automatically detects new uploads from connected creator channels
• Clips — Automated clip extraction from long-form content
• Reframe — Platform-specific formatting (vertical, square, etc.)
• AI B-Roll — Intelligent supplementary footage generation
• Captions — Auto-generated cinematic captions for social platforms
• Destinations — Automated posting directly to TikTok, Instagram, and YouTube Shorts

The combination of Triggers + Destinations is what makes EasySlice truly autonomous — creators connect their channel once, and clips flow automatically from upload to posting without any manual intervention.

These aren't just product features — they're infrastructure.

Søren's Experience as a Solo Founder

Despite being:

• 18 years old
• A college student
• Running a company alone

He still shipped a production product because Mosaic removed an entire class of operational complexity from his workload.

"Although running a business is not easy by yourself… Mosaic's help with bugs, errors, and catastrophic problems has been nothing short of a blessing." — Søren Skarsgard

He also credits Mosaic for:

• Founder support — Direct access to Adish & Kyle
• YC warm intros — Connections to the YC network
• Technical troubleshooting — Fast resolution of issues
• Platform evolution — Continuous improvements to the API
