If you’re building a startup, you don’t need a 40-page business plan—you need clarity.
The Lean Canvas helps founders quickly map out key assumptions, validate ideas, and align the team fast.


🚫 Why Traditional Business Plans Fail

Most founders spend weeks building plans that don’t survive contact with customers:

Lean Canvas is your clarity engine—fast, focused, flexible.


🧩 What Is the Lean Canvas?

A one-page business model tool adapted by Ash Maurya for startups.
It helps you identify and test your riskiest assumptions before scaling.

It covers:

  1. Problem
  2. Customer Segments
  3. Unique Value Proposition
  4. Solution
  5. Channels
  6. Revenue Streams
  7. Cost Structure
  8. Key Metrics
  9. Unfair Advantage

🛠️ How to Fill It Out (in the order that works)

1. Problem & Customer Segments

Define 1–3 real problems + the exact people who feel them.

🎯 “PMs at Series A SaaS startups with remote teams” is better than “startups.”

2. Unique Value Proposition

Use the formula:

[Outcome] + [Time] + [Objection Overcome]
E.g. “Launch your MVP in 30 days—no code required.”

3. Solution

Start with your MVP.
What’s the smallest thing you can build to solve the core problem?

4. Channels

How will you reach your customers now, not ideally?

5. Revenue & Cost

What’s your pricing model?
How much does it cost to acquire and serve a customer?

6. Key Metrics & Unfair Advantage

What drives growth?
What makes you hard to copy (network, data, experience, access)?
