Articles and playbooks.

Every Zrevick article tagged Comparison — how founders turn AI-built products into companies that sell, market and support at scale.

A good comparison saves a quarter of subscription spend; a bad one saves nothing and adds a migration. These articles put competing tools side by side on the criteria that survive vendor churn: integration depth, data portability, oversight controls and cost per outcome at your actual volume. You get honest per-plan math instead of list prices, the switching costs that never make the pricing page, and a migration plan that keeps your pipeline, sequences and history intact through the move. Every comparison here runs the same method — work a real workload through both tools, count the outcomes, and let the numbers eliminate the wrong choice before it reaches your stack. The same method works beyond tool-vs-tool: when a category assembles a shortlist, the guide runs the whole field through one checklist so the differences that matter surface on their own. Start with the alternatives guide for the category you are re-evaluating, then apply its checklist to whatever replaces the incumbent. Re-run the checklist at renewal time — vendors change pricing and terms more often than they change features, and a tool that won last year can lose this year on the same criteria. The tool that wins the demo week loses on month three; the guides are written for month three.

Every article in this section is written for the same reader: a technical founder running sales, marketing and support with a team of one to ten, usually while Claude Code or Codex ships the product. New guides are filed under their topic as they publish, so this page grows rather than ages. If you are mid-decision, start with the most recent article; if you are new to the topic, start with the overview and work forward. Skim the summaries first, then commit to the pieces that match the workflow you are fixing this quarter.
