Lemon Slice Raises $10.5M to Transform AI Interactions

Imagine chatting with an AI assistant that doesn't just respond with text but comes alive through realistic video avatars. That's the future Lemon Slice is building—and investors are betting big on it.

The Technology Behind the Magic

The startup's secret weapon is Lemon Slice-2, a powerful diffusion model packing 20 billion parameters. What makes this remarkable? It can generate smooth video streams at 20 frames per second using just a single GPU—a technical feat that puts realistic avatar interactions within reach of everyday applications.

"Current avatar solutions often feel flat and disconnected," explains founder Lina Colucci. "We're bridging that gap between artificial and authentic interaction."

Businesses can integrate these lifelike avatars through simple APIs or embeddable widgets. Users get creative control too—modifying backgrounds, styles, and appearances on the fly. And it's not just human faces; Lemon Slice specializes in diverse character creation, from fantastical creatures to stylized personas.

Safety First Approach

In an era of deepfake concerns, Lemon Slice emphasizes responsible innovation:

• Strict protections against unauthorized face/voice cloning
• Content moderation powered by large language models
• Transparent implementation guidelines for partners

The company sees particularly strong potential in education and corporate training scenarios where engaging visuals boost learning outcomes.

Competitive Landscape & Future Plans

The digital avatar space is heating up fast with players like D-ID and Synthesia making waves. But Matrix Partners' Ilya Sukhar believes Lemon Slice stands out: "Their technical foundation combined with practical application focus creates real differentiation."

The fresh funding will fuel:

• Engineering team expansion (currently just eight employees)
• Marketing initiatives
• Computational resources for model training With ElevenLabs providing voice technology integration, Lemon Slice appears positioned to deliver complete audiovisual AI experiences.
