&lt;p&gt;&lt;span style=&quot;background-color: transparent; color: rgb(0, 0, 0);&quot;&gt;What made ours trustworthy was keeping the event list short enough that everyone on the team actually knew what each one meant. We used Mixpanel for the initial funnel, and it ended up being less about the tool and more about only tracking the handful of events tied to the one thing we were trying to prove that month.&lt;/span&gt;&lt;/p&gt;

The first analytics setup becomes trustworthy not when it has the most data, but when you can use it to kill an assumption you were fairly confident was true. If your setup can only confirm what you already believe, it&#39;s not doing validation work, it&#39;s just confirming a prior.

&lt;p&gt;&lt;span style=&quot;color: rgb(0, 0, 0);&quot;&gt;PostHog combining funnels, session replay, feature flags, and experiments in one tool is genuinely useful for a technical founding team that needs to validate assumptions fast. Not having to stitch together multiple tools to get that full picture reduces the instrumentation overhead significantly at a stage when engineering time is scarce.&lt;/span&gt;&lt;/p&gt;

Honestly the trap at this stage isn&#39;t picking the wrong tool, it&#39;s instrumenting 200 events before you even know what you&#39;re asking. Pick the three or four events that map to your core assumption and track only those, you can add depth later. The real question: what&#39;s the one assumption you&#39;re trying to prove or kill this month? If you can&#39;t say it in a sentence, no platform is going to save you.
