How to use this playbook

This playbook covers the marketing decisions a SaaS founder has to make before and during growth. Each guide answers one decision, with an example, a table or a worked calculation you can adapt. Read the groups in order if you are starting out, or go straight to the decision in front of you.

Find the market

Who buys, why they choose you, and whether the product is ready for more demand.

Build the plan

The go-to-market plan and the pricing that shapes how you sell.

Generate pipeline

The channels and programs that turn a plan into qualified opportunities.

Check the economics

Whether acquisition pays back, and how much to spend on marketing.

Choose the operating model

How the company grows, and who should run marketing.

Founder rule

Decide in order.

Channel and budget choices made before the ICP and positioning are clear usually have to be made again. Work down the groups in order.
