The Problem Solvers: Kay Zhu at Genspark

Kay Zhu built Genspark on a belief he's living at home: that AI should free people to follow their heart. His teenage son is studying commercial dance instead of computer science with his full support. As CTO and co-founder, Kay built Genspark to make that possible at scale with an all-in-one AI workspace for business. In a market moving this fast, anyone can build, but Kay believes the team is what makes the difference. He chose Claude for its reasoning capabilities, and found something beyond the model: a close partnership with Anthropic that let him take Genspark further than he could alone. The Problem Solvers is a series from Anthropic speaking to founders about how they're solving problems, and why they build with Claude.

WHAT IT’S REALLY ABOUT

Kay Zhu on AI workspaces, culture moats, and trust partnerships

  1. Kay Zhu argues that as AI accelerates, people should feel freer to pursue their passions because AI will handle more routine work.
  2. Genspark is positioned as an all-in-one AI workspace offering AI-powered spreadsheets, slides, documents, and other tools for everyday white-collar tasks.
  3. She describes collaboration with an Applied AI team as energizing for engineers and essential for a small startup that can’t build everything alone.
  4. Zhu challenges the idea of durable “moats,” claiming the only real moat is team culture that drives curiosity, openness, and fast execution.
  5. She emphasizes that successful partnerships rely on deep mutual trust and tight feedback loops, and that the company’s future is intentionally uncertain due to rapid change.

IDEAS WORTH REMEMBERING

5 ideas

AI shifts the calculus of career and study choices.

Zhu’s anecdote about her son choosing commercial dance illustrates her belief that AI will absorb more practical/technical workload, making it more viable to “follow your heart” without sacrificing future stability.

Genspark targets mainstream knowledge work, not niche AI users.

By focusing on AI spreadsheets, slides, and documents, Genspark is aimed at normal white-collar workflows where small productivity gains can compound across many tasks.

For small startups, partnerships are a force multiplier.

Zhu frames incoming collaboration requests as an “invitation to the party,” while also noting a small team can’t do everything—trusted partners help them move faster and cover gaps.

In today’s AI market, culture may outlast product advantages.

She claims traditional moats erode quickly because capabilities diffuse fast; a culture of curiosity, exploration, and rapid execution becomes the differentiator.

Openness beats hoarding secrets when the shelf life of information is short.

Zhu argues that secrets can become “worthless tomorrow,” so sharing and collaborating can produce more value than guarding transient advantages.
