Pre-requisites

Market research and customer conversations to understand the landscape.

Startups are nothing but a series of validations. In the end, you want to know if the juice is worth the squeeze: will this business fly?

Think of Assumption Mapping as your startup's secret weapon to validation. It helps you uncover, prioritise, and validate the key assumptions driving your idea. By zeroing in on the riskiest assumptions – i.e. what really matters, you can allocate time & effort smarter and move forward with confidence.

An assumption is an ‘expected truth’ about your business idea. Imagine you’re building an organic baby food subscription service. Here are some possible assumptions you might make:

• People want a baby food subscription.
• Packaging can be safe for babies and can be environmentally friendly.
• A short supply chain will save CO2 and keep food fresh.

Assumptions answer the question:

What do we need to prove to make this startup succeed?
