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.

  1. 0:00 – 0:30

    Why AI changes what to study: “follow your heart” careers

    Kay Zhu reflects on how AI is reshaping career planning, using her son’s choice to study commercial dance as an example. She argues that as AI takes on more tasks, people can lean more into passion-driven paths.

    • Personal story about her son choosing dance over computer science
    • AI reduces the need to optimize purely for “safe” technical majors
    • Encouragement to pursue interests as AI boosts productivity across fields
  2. 0:30 – 0:49

    What Genspark is building: an all-in-one AI workspace

    Kay describes Genspark’s product focus: AI tools embedded into core office workflows. The goal is to help everyday white-collar workers with spreadsheets, slides, documents, and more.

    • Positioning: “all-in-one AI workspace”
    • Product areas: AI spreadsheet, AI slides, AI document
    • Target users: normal white-collar workers and their daily tasks
  3. 0:49 – 1:00

    Working with Applied AI: new requests as a catalyst

    Kay explains how her engineering team responds to new collaborations and inputs from Applied AI. She frames it as energizing—an opportunity to stay close to the latest model advances.

    • Engineers are motivated by new model advancements
    • Incoming requests feel like an “invitation to the party”
    • Collaboration is enjoyable and accelerates learning
  4. 1:00 – 1:11

    Why partnerships matter for a small startup

    She emphasizes the practical reality of operating as a small team: they can’t build everything alone. Trusted partners help extend capability and move faster without compromising reliability.

    • Resource constraints of a small startup
    • Need to focus and leverage external expertise
    • Importance of working with trusted partners
  5. 1:11 – 1:13

    Rethinking the ‘moat’: speed and culture over defensibility

    Kay challenges the common startup fixation on defensibility, arguing that in fast-moving AI markets, traditional moats erode quickly. She sees team culture—curiosity, experimentation, and execution speed—as the real durable advantage.

    • Skepticism that any company has a lasting moat right now
    • AI ecosystem changes too fast for static advantages
    • Culture as the primary competitive edge
    • Bias toward exploring and adopting new technology quickly
  6. 1:13 – 1:37

    Openness as a strategy: secrets expire fast in AI

    Kay argues that openness is crucial in collaboration because the value of withheld information decays rapidly. In her view, sharing and iterating beats hoarding in a landscape where breakthroughs quickly become baseline.

    • Openness is key to successful collaboration
    • Information hoarding has diminishing returns
    • Today’s secrets may be worthless tomorrow
  7. 1:37

    How great partnerships work: trust and tight feedback loops

    She outlines the mechanics of productive partnerships: deep mutual trust and rapid iteration. When it works well, feedback cycles are tight and progress compounds quickly.

    • Deep mutual trust as the foundation
    • Tight feedback loops drive execution speed
    • Collaboration quality determines outcome
  8. Embracing uncertainty: Genspark’s future will feel like magic

    Kay closes by describing how unpredictable the next few years will be for Genspark and AI more broadly. Rather than offering a fixed roadmap, she expects rapid change and surprising capabilities that may feel “like magic.”

    • Rejects fixed long-term predictions for a two-year horizon
    • Anticipates major shifts and new opportunities
    • Expectation of seemingly magical AI progress
