Building in Public: What to Share and What to Keep Private

Introduction

Building in public — sharing progress, metrics, and lessons openly — has become a popular growth channel for founders, but there's a real line between transparency that builds trust and disclosure that creates competitive or legal risk.

What's Genuinely Safe to Share

Lessons learned, process decisions, high-level progress milestones, and general growth trends (without exact figures) all build credibility without meaningfully helping a competitor. Sharing the reasoning behind a decision is usually safer and more interesting to an audience than sharing the raw underlying data.

What to Keep Private

Exact revenue figures, specific customer names without explicit permission, unresolved security issues, and anything that reveals a specific competitive strategy before it's executed are all worth keeping private. Once shared publicly, this information can't be un-shared, and competitors read founder content too.

The Trust-Building Effect

Consistent, honest building-in-public content — including sharing setbacks, not just wins — builds a level of audience trust that polished marketing rarely achieves. Audiences can tell the difference between curated wins and genuine, occasionally messy progress.

Common Mistakes

Oversharing metrics before they're meaningful (a single good week presented as a trend), or being publicly critical of specific customers or employees, are among the most common building-in-public mistakes that create lasting reputational cost.

Conclusion

Building in public works best as a curated version of honesty — genuinely transparent about process and lessons, deliberately private about anything that creates real competitive or legal exposure.
