Part II — For Investors
Investor Pitch
The condensed version for people who write checks.
The Opportunity
The Problem
Knowledge workers spend 60% of their time on "work about work"—searching, organizing, remembering, context-switching. The tools meant to help (Notion, Todoist, Anki, etc.) are fragmented, passive, and don't talk to each other.
Meanwhile, AI is transforming every category of software—except the tools we use to think.
The Solution
brain.bike is an integrated cognitive toolkit: four interconnected applications that help people learn, remember, achieve, and focus.
Unlike point solutions, brain.bike is a system:
- Notes become flashcards automatically
- Goals become tasks become reminders
- AI handles friction while humans do the thinking
Why Now
- AI maturity: LLMs can now write formulas, extract flashcards, decompose goals—removing friction that made integrated tools impractical before
- Tool fatigue: Users are exhausted by app sprawl and ready for consolidation
- Remote work permanence: Self-directed productivity tools are now essential, not optional
The Product
| Tool | Function | Key Differentiator |
|---|---|---|
| Nudger | Active attention management | Brings users back—doesn't wait for them |
| Loopforward | Goal tracking + task management | AI agents for delegatable subtasks |
| Markdown | Note-taking with AI assistance | Click-to-source, formula help, real-time render |
| Ankify | Flashcard generation + spaced repetition | Auto-generates from notes, not manual entry |
Integration is the product. Each tool enhances the others. Switching cost is high. Value compounds with use.
Business Model

Why brain.bike
Steve Jobs said the computer is "a bicycle for the mind."
Most software today is a treadmill—lots of motion, no progress.
We're building the actual bicycle.
