Are you over-indexed on acquisition?

Too many deals churning after 18 months? Is your onboarding sequence not really driving the activation you need? How many expansion opportunities are you missing across your top accounts? Is your renewal process 90% manual outreach in the final 30 days? Is your CS team spending more time fighting churn fires than preventing them? 

If you're nodding along, you're not alone. Most B2B companies spend 70% of their budget acquiring customers and just 5% engaging and growing them.

This backwards allocation explains why you're missing growth targets, dealing with 15-20% churn rates and missing millions in untapped expansion revenue. 

Your existing customers are your highest-ROI growth channel, but they're getting the least attention and investment.

The Real Cost of Reactive Customer Management

Here's what drives me crazy about this industry: companies will spend months optimizing an ad campaign or landing page, but totally skip building proactive post-acquisition customer engagement and growth systems.

Did you know that existing customers are 3-12x more likely to expand and cost 5x less to grow than acquiring new ones? 

You're ignoring 8x ROI on existing customers to chase breakeven on new ones.
