2. Growth PMs: Data-driven and skeptical, focused on metrics and experimentation.

3. Business/GM PMs: Strategic thinkers who prioritize business models and margins.

4. Platform PMs: Builders of scalable systems and tools for others.

5. Research/AI PMs: Deeply technical with a strong product sense, ideal for AI-driven products.

- Teams thrive when these archetypes are balanced, creating a team of Avengers with complementary strengths.
