Our Core Principles at Needle
Building a startup is a journey filled with lessons, pivots, and unexpected challenges
Key Takeaways
- Needle is built on 3 core principles: Consistency, Growth through compounding effort, and Self-reinforcing success
- Consistency (f(x) = a) is the foundation - stable execution beats chasing every new idea
- Growth is the integral of consistent workload: small, deliberate steps compound over time
- 4 core beliefs guide every decision: execution over ideas, consistency, simplicity, and long-term thinking
Building a startup is a journey filled with lessons, pivots, and unexpected challenges. As we continue to grow, we've realized that certain principles guide our decisions, shape our culture, and define our success. Here's what we've learned so far:
Principle 1: Consistency

Equation: f(x) = a
Our early days were filled with uncertainty, but we quickly learned that stability is key. Instead of chasing every new idea, we focused on consistent execution.
Principle 2: Growth = ∫ Workload dx

Equation: f(x) = ax + b
To grow, we had to embrace consistency. Every decision, every product, every hire update compounds over time. The lesson? Small, deliberate steps lead to sustainable growth, rather than expecting overnight success.
Principle 3: Success = ∫ Growth dx

Equation: f(x) = ax^2 + bx + c
Growth leads again to more growth. Hence it is a self-reinforcing effect.
How the 3 Principles Build on Each Other
| Principle | Equation | What It Means | Startup Example |
|---|---|---|---|
| 1. Consistency | f(x) = a | Stable, repeatable execution | Ship every week, blog every week |
| 2. Growth | f(x) = ax + b | Effort compounds linearly | Each feature adds users, each hire adds output |
| 3. Success | f(x) = ax² + bx + c | Growth becomes self-reinforcing | Network effects, word-of-mouth, compounding revenue |
Our 4 Core Beliefs
Execution matters more than ideas. A good idea with poor execution goes nowhere.
Consistency is the most undervalued skill. The necessary key metric is to build constantly over time.
Simplicity beats complexity. The best solutions are often the simplest.
Long-term thinking wins. Short-term wins are great, but we're here to build something that lasts.
Summary
Needle's 3 core principles - Consistency, Growth through compounding effort, and Self-reinforcing success - form a mathematical framework for building a sustainable startup. Combined with 4 core beliefs (execution over ideas, consistency, simplicity, and long-term thinking), these principles shape every decision we make. The takeaway: small, deliberate, consistent steps compound into lasting success.
