Gumroad's CEO credits their rapid development to his role as a solo decision-maker. This structure eliminates the lengthy processes of gaining internal buy-in and creating extensive documentation (PRDs, specs) common in larger organizations, which are often more about alignment than execution.

Sundial founder Julie Zhu intentionally avoids hiring product managers. This constraint forces engineers to take full ownership of the product definition and user value, preventing them from delegating critical product thinking and developing a stronger sense of customer empathy.

Vercel created a separate business unit for its AI tool, V0, because it targets a different audience (PMs, designers) and needed to operate with extreme speed, unburdened by the decision-making processes of the larger 700-person parent company.

The team avoids traditional design reviews and handoffs, fostering a "process-allergic" culture where everyone obsessively builds and iterates directly on the product. This chaotic but passionate approach is key to their speed and quality, allowing them to move fast, make mistakes, and fix them quickly.

In an organization still running in project mode, the 'Product Manager' title is misleading. The role is often relegated to organizing work and scheduling tasks for engineering. A true product model requires empowering these roles with the mandate, skills, and market access to make strategic decisions.

To maximize speed, V0 operates with a "no handoffs" philosophy. Everyone, including designers and product managers, is expected to contribute code and submit their own pull requests. This "full-stack PM" model minimizes the coordination costs and wasted cycles of explaining changes.

When pursuing a long-term strategic solution, dedicate product management time to high-level discovery and partner alignment first. This doesn't consume engineering resources, allowing the dev team to remain focused on mitigating the immediate, more visceral aspects of the problem.

The AMP team is small and agile, bypassing traditional processes like code reviews to ship 15 times a day. They leverage Sourcegraph's customer trust, revenue, and platform teams (e.g., security), allowing the core team to focus purely on product velocity and radical innovation.

The V0 team dogfoods their own AI prototyping tool to define and communicate new features internally. Instead of writing specification documents, PMs build and share working prototypes. This provides immediate clarity and sparks more effective, tangible feedback from the entire team.
