YOUR PRODUCT IS NOT THE CENTER OF THE UNIVERSE

Classical traits of product-centric thinking include expecting people to come to you to get work done, building integrations so other products plug directly into you, asking people for context and preferences they've already shared somewhere else, and trying to own AI access by building a custom agent inside a product. This product-centric view has an expiry date. Coding and personal agents can now work across several tools, and now visiting each product one at a time is starting to feel like friction. The products that will thrive will put the user, along with their agent of choice, at the center.

WE STOPPED REVIEWING CODE AND STARTED VERIFYING INTENT

When AI writes most of the code, human review is best spent on what the change should do. Scaling diff review to match AI output doesn't work. Review intent before code is generated, and verify each criterion with evidence. Turn recurring review comments into invariants, and keep humans on the decisions and on ownership of the rules. This should result in code review no longer being the bottleneck.

PUBLISH INTERACTIVE APPS FROM THE GEMINI APP TO GOOGLE SITES

Interactive apps built in the Gemini app can now be exported directly to Google Sites. Apps are added to a new and private draft site. Users can add more content, publish the site, and share it just like any other Google Site. There is no new admin control for the feature - users can export to Google Sites if the feature is turned on for them and they are allowed to create and edit sites. The export feature is available to Google Workspace customers, Workspace Individual subscribers, and users with personal Google accounts who have access to the Gemini app.

PIVOT!

Many founders fear the word 'pivot', but if you're on a path that isn't leading to a great outcome, you must make bold moves. Admitting that the current strategies aren't working may be the only way forward. A pivot is a chance to redefine a company and refocus everyone on a winning strategy. The real risk is trying to make incremental change in a deteriorating business.

DON'T DO "DRIVE-BY RECRUITMENT"

Low-effort cold emails from founders are a huge bear signal on the company. Founders who send them are deeply uncalibrated about what it takes to recruit good people. This is especially true if they go cold immediately after a rejection. Recruiting is sales - these things are a relationship game. Next time a founder says that it's impossible to hire good engineers, consider that they might just be terrible at it.
