Building the Product

How do I set up analytics and feedback in my MVP so I actually learn something, without over-engineering tracking?

A starting point

Instrument the two or three moments that prove your core assumption (did they reach the aha, did they come back, did they pay) and ignore the rest for now. Pair a lightweight product analytics tool (PostHog, Mixpanel) with direct conversation: five recorded user calls will teach you more than a dashboard of clicks at this stage. The failure mode is drowning in metrics you'll never act on. This is a starting point, expand instrumentation as specific questions come up.

Why we picked it The single best thing ever written on customer conversations. It teaches you to ask about the customer's life and past behaviour, not your idea, so you can't be lied to. If a founder reads one thing before talking to a single customer, it's this.

The Mom Test

From momtestbook.com by Rob Fitzpatrick ~130 pages

  • Talk about their life, not your idea.
  • Ask about specifics in the past, not opinions about the future.
  • 'That's so cool, I'd totally buy it' is a compliment, not data, dig for commitment and evidence.

Why we picked it The biggest tracking mistake in an MVP is measuring everything and learning nothing. This Amplitude piece walks you through picking one metric that maps to real customer value and finding the early aha moment that predicts whether people stick around, which tells you the few events actually worth tracking. Treat it as a starting point for focus, not a rule: a small product is still learning what matters, so revisit your metric as you go.

Every Product Needs a North Star Metric: Here's How to Find Yours

From Amplitude by Julia Sholtz

  • A good North Star Metric is a leading indicator of value delivered, not a lagging number like monthly revenue.
  • Find the early aha action that predicts retention (the classic example is Facebook users adding seven friends in ten days) and instrument that first.
  • Choosing one metric and a few inputs keeps your tracking small and honest instead of a dashboard nobody reads.

Why we picked it PostHog gives you product analytics and session replay in one place, so you can see both what people did (events, funnels) and watch a real session to understand why they got stuck. It is open source and self-hostable, and the free tier (1 million events and 5,000 session recordings a month) covers most MVPs without a card. That mix of numbers plus watching real sessions is exactly what keeps you from over-instrumenting: you track a few events, then watch replays to fill in the story.

PostHog

From posthog.com by PostHog

  • One tool covers both quantitative events and qualitative session replay, so you learn the what and the why without stitching together two products.
  • The free tier is generous enough for a real MVP, and self-hosting is an option if you want full control of your data.
  • Start by tracking a handful of key actions (signup, activation, the core action), then use session recordings to understand the drop-offs instead of adding more and more events.
