FAQPage Schema
How do I identify the best growth channels for my startup?

To identify winning growth channels, score your acquisition channels by combining CAC, retention, and scalability data to reveal a golden channel. This requires structured metrics from existing marketing efforts to highlight the most effective channel.

What is a golden channel and how do I calculate it?

A golden channel is your highest performing acquisition channel, calculated by scoring and combining Customer Acquisition Cost (CAC), retention rates, and scalability data to determine which channel drives the most sustainable growth.

How do I build a 90-day growth roadmap for my marketing channels?

You build a 90-day growth roadmap by running phase-driven experiments across your marketing channels, collecting traction data, and assembling the results into a concrete growth playbook to maintain monthly accountability.

Does this growth playbook approach work for startups with multiple marketing channels?

Yes, this approach is designed specifically for startups with multiple marketing channels and existing traction data, using CAC and retention metrics to optimize channel inventory and scale acquisition effectively.

How many growth experiments do I need to run when optimizing channels?

You need a plan for 1-2 structured growth experiments to validate channel scalability and retention metrics before assembling your final 90-day growth roadmap and playbook.

When should I not use a phase-driven growth playbook?

You should avoid using a phase-driven growth playbook if your startup lacks structured metrics like CAC and retention data, or if you have no existing traction across multiple marketing channels to evaluate.
