Linear intentionally keeps teams small, viewing limited bandwidth not as a bug, but as a feature. This constraint forces the company to focus only on the most critical initiatives and avoid launching unnecessary features. It prevents the common startup pitfall of building things just to keep a growing team busy.

To manage an infinite stream of feature requests for their horizontal product, Missive's founders relied on a simple filter: "Would I use that myself?" This strict dogfooding approach allowed the bootstrapped team to stay focused, avoid feature bloat, and build a product they genuinely loved using.

The old product leadership model was a "rat race" of adding features and specs. The new model prioritizes deep user understanding and data to solve the core problem, even if it results in fewer features on the box.

Adopt an "unshipping" culture. If a feature doesn't meet a predefined usage bar after launch, delete it. While a small subset of users may be upset, removing the feature reduces clutter and confusion for the majority, leading to a better overall user experience.

The biggest pitfall in product development is believing one more feature will make it great. Truly successful products, like GitHub with the pull request or Dropbox with its sync icon, have a single, exceptionally good "tiny core" that serves as their superpower.

Jack Dorsey reframed the Product Manager role as "Product Editor." The most valuable skill is not generating new feature ideas, but exercising judgment to cut through the noise, simplify complexity, and edit the product down to the essential few things that truly drive customer outcomes.

Many founders become too attached to what they've built. The ability to unemotionally kill products that aren't working—even core parts of the business—is a superpower. This prevents wasting resources and allows for the rapid pivots necessary to find true product-market fit.

Founders are naturally dreamers, but execution requires ruthless prioritizing. The most critical, and difficult, role is saying 'no' to shiny objects and good ideas to maintain focus. This clarity is more important than simply working long hours.

A feature that customers love after buying, like 24/7 Slack access, may not be a primary driver for the sale itself. If it consumes significant founder time and prevents scaling, it should be eliminated to improve business health without significantly impacting new customer acquisition.
