The \

You used to run a billion-user product at a massive tech corporation. You’re used to resource leverage, massive traffic, and mature systems. Then you quit to start an AI company. Suddenly, you’re sitting in the dark at 3 AM, manually replying to snarky comments on Twitter, desperately battling time zones just to keep your product alive. Welcome to the real world of AI entrepreneurship.

This is the story of Kiki. She spent nine years at ByteDance, building CapCut (Jianying) from scratch and watching it grow into a global giant with over 100 million daily active users. In early 2026, she left the empire to found OJO, an AI agent workspace for the design industry. What she learned on the outside defies every conventional Silicon Valley playbook. Steering a billion-user product doesn’t prepare you for the absolute chaos of an AI startup. Sometimes, it’s the exact baggage that kills you.

Look at today’s AI application layer. It’s a graveyard. Why? Because founders are falling into two fatal traps. Trap number one: the \”All-in-One\” illusion. Every startup wants to build the ultimate super-app that does everything for everyone. Kiki is blunt about this: products that try to be all-encompassing on day one are guaranteed to die. You don’t have the massive error-tolerance budget of a big tech company. You need extreme focus. Find one single point, completely nail it, or pivot immediately.

Blind persistence on the wrong seed, growing more stubborn as you go, is the most elegant form of startup suicide.

Trap number two: old wine in new bottles. Too many teams are just slapping an AI label onto a decade-old scenario. They try to use AI to reconstruct the old Figma workflow or the old video editing timeline. But generative AI is fundamentally restructuring the base layer of production. If you’re using new technology to fight for turf in an old, stagnant market, you’ve already lost.

OJO’s real insight isn’t just building another design tool. It’s a dynamic team of Agents. You can summon a \”Steve Jobs\” Agent to challenge your product logic, or a \”Van Gogh\” Agent to push your aesthetic boundaries. Why? Because design is a deeply fragmented, skill-intensive industry, and AI is flattening it. Product managers can now generate design drafts. Designers can write code. The rigid upstream-downstream production relationship is dead.

But here is the core tension that nobody wants to talk about. Coding models are optimized to be fundamentally \”correct.\” They will sacrifice visual aesthetics to ensure the underlying logic doesn’t break. They generate things that work, but they are inherently ugly. Users don’t want correct; they want beautiful. The model wants to be right; the user wants to be stunned. The entire point of the application layer is to bridge that gap.

The real moat isn’t the foundational model itself, nor is it having the most features. It’s about whether you can orchestrate the model’s upper limits in a specific vertical through precise dispatch mechanisms—like distinct Skills and Agent teams. If you just wrap a UI around a model and pray, you will be washed out. You have to build the harnesses, the tools, and the loops that force the model to deliver peak results in that specific domain.

So, how do you validate this moat? Kiki didn’t use her ByteDance connections. She didn’t hire an expensive overseas agency. She didn’t drop a massive marketing budget. Her team consisted of exactly one marketing lead and three interns. They went into overseas geek communities and did the most primitive, grueling manual outreach to find seed users. They turned on the payment gateway on day one.

When the product went viral and the direct messages exploded, did they use AI automated replies to handle the load? Absolutely not. They replied manually to every single person. Automation is a cutoff switch to your user nerve endings. In the early days, manually replying to every message isn’t grunt work; it’s your most vital product research.

They stayed up until 5 AM, rotating shifts to catch the active hours of North American users. They cracked jokes on Twitter, acting like living, breathing humans to build genuine trust. That \”alive feeling\” is something you cannot buy with venture capital.

Stop trying to be the next Figma. Stop trying to do everything. The AI era doesn’t reward resource leverage; it rewards a deep, almost obsessive understanding of model boundaries, and the willingness to do the dumbest, most primitive hard work to capture real user signals. If you aren’t willing to manually reply to your users at 3 AM, you don’t deserve to survive.
