Frequently Asked Questions

Should I hire an agency or build internal? Agencies provide broad expertise and velocity; employees offer dedicated focus. Many SaaS companies use agencies to establish foundation and validate channels, then hire teams to execute proven playbooks.

What results can I expect in 3-6 months? Months 1-3 emphasize strategy and initial experiments with early pipeline. Months 4-6 demonstrate measurable pipeline contribution and clear channel winners. Substantial revenue impact typically requires 6-12 months.

How should I measure agency performance? Focus on pipeline generated, revenue influenced, CAC/LTV trends, conversion improvements, and payback period reduction. Avoid vanity metrics.

Should I prioritize acquisition or expansion? Both matter, balanced by stage. Early-stage prioritizes acquisition validating product-market fit; growth-stage increasingly emphasizes expansion as more efficient than new acquisition.

Does my company need PLG? Product-led growth succeeds with rapid time-to-value, clear activation moments, and value delivery without heavy implementation. Complex or highly customized solutions typically require sales-led approaches. Hybrid models increasingly common.
