There's a better use for our attention.

A product can keep you busy for years and leave you no closer to a single person. We've all used a few. Some of us have built a few. That sentence is the thing I wrestle with most as a founder, because the entire playbook I inherited points the other way. # The easy number and the hard one Retention is the easy number. Did they come back today, this week, this month. It's clean, it goes on a slide, it's what everyone asks about first. I can instrument it in an afternoon. Whether it was worth coming back is the hard number. That one doesn't sit in an analytics dashboard. It shows up as a reply from someone who was there. A question that turned into an actual call. A story someone finally told because the app nudged them and they took the nudge to a person instead of a screen. The uncomfortable part is that the easy number and the hard number can point in opposite directions. You can juice time-in-app with the same tricks everyone else uses — streaks, badges, a little intermittent-reward slot machine — and watch retention climb while the thing you claimed to care about flatlines. Boring on a slide. Corrosive in six months. # The red line So Zibby has a red line, and it's simpler than it sounds: the red line is rumination. No mortality marketing. No "your memories are slipping away, act now." No engineered anxiety loop that gets you to open the app by making you feel worse if you don't. Those tactics work. They'd probably work on this exact product, which is precisely why I have to name the line out loud, in writing, before the growth pressure shows up and makes the case for crossing it. Zibby can only win if it makes people's lives better in real ways, not if it just makes them come back. If the only thing I can prove is that usage went up, I haven't proven the thing I set out to prove. # Measuring the right thing is harder, and that's the job I don't have this fully solved. Measuring connection is harder than measuring sessions, and I won't pretend otherwise. But "it's hard to measure" has been the industry's excuse for optimizing the easy thing for fifteen years, and I'm not interested in inheriting that excuse. So I care about what happens around the memory. The call it started. The person who was brought in and stayed. The retelling that only happened because someone got asked. Those are messier to count. They're also the only outcomes that would make me proud of what I built. There's a better use for our attention than keeping it. What's made you feel closer to someone lately? If Zibby had a hand in it, I want to know how. If it didn't, that teaches me something too.
