The Startup That Moves to a Metronome

How One Founder's Ballet Training Became Her Blueprint for Building

Tik. Tik. Tik. The rhythm in Lina Colucci’s childhood ballet studio never lied. Every beat demanded precision, every pause held purpose. Years later, building the world's first interactive AI video model, she'd discover that it requires the same unwavering discipline.


"Dance is where I feel most alive," Lina explains. "It's this peak life experience where my body, heart, and mind all align."


But what many people don’t understand about dance is that the magic on stage —that effortless, flowing performance — only comes with thousands of hours at the Barre."

Just like a dancer can't skip the barre work to get to the stage, we couldn't skip the foundational research to reach real-time interaction."

Every morning became a new repetition: Put in the work. Review results. Push forward. Repeat.

"As we train foundation models, every day we pull up results that no one else in the world has seen yet," says Lina. "It's like being a 16th-century explorer discovering uncharted territory."


Late nights. Incremental progress. Models sometimes worked; sometimes they didn't. But Lina understood that breakthrough moments aren't accidents; they're the product of showing up when progress feels invisible.


"I believe that reaching your full potential takes both working hard and putting yourself out there every day."


Small improvements compound, muscle memory builds, and eventually the impossible becomes fluid.

Then came April.


After countless training runs and improvements to shave off milliseconds, Lina’s San Francisco-based Lemon Slice released the world's first interactive talking AI video model. "Real-time interactive AI video is a new media format that has only recently become possible," she says. "We're building a future where  all video is interactive and personalized to the viewer."


The technology was so novel that they needed to show people what it could do.



Lina’s solution? Make it entertaining. Performance as a product demo. Art as marketing.


Now they're launching an improved version. But for her, each launch represents something bigger.

“I want our product launches to feel like a magical, effortless performance," she says.
"That conscious balance between practice and performance, that's what dance taught me."

Video has been a passive, one-way medium for over a century. Lemon Slice is making it conversational, a shift she compares to the impact of large language models on text.

The metronome keeps ticking.

She still dances, still finds that alignment. Put in the work. Push forward. See what no one has seen. Repeat.


We're integrating frontier AI research with creativity," says Lina. "That intersection of engineering and the arts, that's central to who I am."


Every beat demands precision. Every pause holds purpose. And somewhere between the practice and the performance, the future becomes real.

The difference between impossible and inevitable? That's about a thousand training runs you haven't done yet.
