One human. Many agents. Infinite experiments.
Hi, I’m Huan — the Founding Human behind PreAngel, a one‑person startup incubator that doesn’t build alone.
At first glance, PreAngel might look like a solo venture. But in practice, it’s a company of one working side by side with autonomous AI agents — named, role‑defined, memory‑augmented, and deeply integrated into how I design, build, and ship products.
Together, we’re building tools like:
- ReKey — an AI-powered keyboard that rewrites your English to sound fluent, natural, and expressive.
- ReMic — a real-time, bilingual voice interpreter that bridges spoken communication between humans.
These aren’t just “AI features” glued onto legacy tools.
They are AI-native products, architected from the ground up for a world where AI isn’t just a backend, but a partner.
🧠 AI-Native, Human-First
Every product I build starts with one question:
What happens when AI is the first teammate, not the last add‑on?
At PreAngel, I focus on AI-native product design, rethinking UI, UX, and workflows to make AI feel collaborative — not controlling. I believe in human‑AI interaction that empowers the user, maintains agency, and builds trust.
Because the point isn’t just intelligence.
It’s fluency. It’s connection.
🧩 Many Agents. One Architect
Under the hood, PreAngel runs on an agent-based architecture: modular AI agents with names, responsibilities, and role memory. I build tools using AI agent orchestration — managing conversation state, functional logic, and coordination between autonomous components.
It’s not just prompt engineering. It’s multi‑agent system design for real‑world use cases.
🚢 Ship.Fast, Fail.Forward
Beyond our flagship tools, I also run Ship.Fail — a sandbox for small, fast, weird product ideas.
The philosophy is simple:
- Build fast
- Learn loud
- Fail forward
Some projects launch in a day. Some evolve. Some die with grace.
But every one of them is a small bet — and each one teaches me something true.
This is my personal build‑fail‑learn loop. It’s where I stretch ideas, test assumptions, and sharpen product intuition.
🧱 Systems for a Company of One
To move fast alone, I’ve built internal systems that handle:
- Agent lifecycle & role config
- Firebase-powered infrastructure
- Stripe + Apple IAP monetization
- Launch, growth, and user feedback loops
These solo founder systems let me act like a full‑stack startup studio — without the startup bloat.
But more than systems, I build stories.
Whether it’s an AI interpreter or a rewrite keyboard, each product starts with a core narrative — about making people feel seen, heard, and more fluent in who they are.
That’s what I call narrative‑driven product design.
✨ Let’s Build the Future, Together
If you’re a solo founder, AI builder, researcher, or agent explorer — let’s connect.
This new era isn’t about replacing humans.
It’s about working with AI to build what was once impossible.
I believe in that future — and I’m shipping it, one small bet at a time.
Warmly,
Huan Li
Founding Human & Architect @ PreAngel
If you’ve made it this far, thank you. For those curious about how I actually work and what I practice — here’s a peek into the skills I’ve been cultivating as I build PreAngel, ReKey, ReMic, and everything in between.
🧠 Founder Skill Tree — What I’ve Been Practicing at PreAngel
Sometimes, building a company of one means wearing every hat — architect, poet, operator, explorer. Below are the principles and practices I return to often as I build ReKey, ReMic, and whatever’s next:
🧠 AI Native
Designing products where AI isn’t an add-on — it is the architecture.
At PreAngel, every tool starts from an AI-first core, not a retrofit.
🤝 Human AI Interaction
Crafting systems where AI collaborates with humans, not replaces them.
Interfaces are designed to feel like partnerships, not command lines.
🧩 AI First
Building user experiences optimized for real-time, generative collaboration.
I rethink UI/UX through the lens of how LLMs respond, adapt, and fail gracefully.
💡 Idea Incubation
Turning raw sparks into testable products through rapid iteration.
Ship.Fail is my founder lab — a studio model built into a solo startup.
🌀 Design Sprints
Time-boxed creative bursts for validating bold product ideas.
At PreAngel, sprints drive momentum, clarity, and continuous shipping.
🔁 Build Fail Learn Loop
Shipping fast, failing publicly, learning deeply.
Every experiment at PreAngel fuels the next — from microtools to agent behaviors.
⚡ One Day Product Building
From concept to working MVP in 24 hours.
This is how I sharpen instincts, test assumptions, and move ideas forward without friction.
🛠️ Solo Founder Systems
Scalable workflows for building, shipping, and iterating as a team of one.
I automate and templatize everything from launches to feedback to learning loops.
🧘 Fail Forward Product Mindset
Using failure as a feature, not a flaw.
Ship.Fail is a philosophy — not just about surviving missteps, but growing through them.
🎯 Small Bets Strategy
Placing focused, minimal-risk bets across many ideas.
Instead of chasing unicorns, I explore multiple pathways and double down on signal.
🧬 Narrative Driven Product Design
Designing tools that tell stories, not just perform functions.
From interface copy to agent personalities, every product reflects emotional clarity and intent.
