Growth gets discussed badly. Either someone is selling a "growth hack" that quietly assumes you already have product–market fit, or you are stuck reading a corporate playbook written for a company with a 12-person paid acquisition team. Neither helps when you are an indie SaaS founder trying to push from €5K MRR to €15K MRR with one engineer and zero ad budget. The articles in this category are written for that gap.
What we mean by growth here is the slow, compounding kind: pricing experiments that lift ARPU without scaring off paying users; onboarding tweaks that move 30-day retention by five points; cohort observations that tell you which acquisition channel is actually paying back; positioning shifts that double trial-to-paid conversion without changing the product. None of those require a growth team. All of them require honest measurement, which is the recurring theme on this blog.
If you are deciding where to spend the next month, three pieces are worth reading first. CAC payback period for SaaS founders is the math that tells you whether your acquisition is even sustainable, before you optimize anything. Average CAC SaaS benchmarks gives you a sanity check against industry numbers so you stop comparing yourself to companies that raised €40M. Cohort analysis for SaaS founders shows you the one chart that exposes growth that is real versus growth that is just churn-masked.
The hardest part of growth at the indie scale is not finding tactics. It is having the patience to keep measuring after the spike fades, separating the move that worked from the noise that always shows up alongside it. That is the discipline this category is trying to build — not new hacks, but better instruments. Pick the article closest to the question on your desk this week and start there. Most of them link out to a calculator or a methodology page so you can apply the framework to your own Stripe data inside ten minutes.
