NotebookLM

NotebookLM's podcast feature started as an after-hours experiment by two teammates. The first NotebookLM podcast came from two teammates at 6:30 p.m. on a Tuesday. When the AI hosts made dry British Parliament debates interesting, the team took that surprise as the signal to build on it.

Josh Woodward, VP of Google Labs, says real hits start with a surprise, and that excitement alone is weak: look for a behavior shift and a group who can't live without the product. He notes that many attempts fail, so it is partly a game of numbers.

Small obsessed groups hacking on side projects produced NotebookLM, not ideation sprints. NotebookLM, Flow, AI Studio and Google Beam each began with a very small, obsessed group over the last four or five years. Labs creates space for those side projects and watches for the one that catches its eye.

Ideas tend to appear on weekends, over breaks or in the hallway, not in scheduled idea meetings. "You can't microwave good ideas."

When fit is obvious, swarm it and hold on. Woodward lists NotebookLM podcasts alongside Nano Banana, Flow and Stitch as moments of real product-market fit, where the team ended up swarming the product and "holding on for dear life."

He calls the swarm "so exhausting and so fun" and says teams should love the problem rather than the solution, since finding a product can take three, four or five pivots.
