Most founders don’t come from a product management background, yet in the early stages of building a company this discipline can be essential to your startup’s success. While it can be tempting to hire a product manager right away, it often leads to overpaying for a team member who ends up being a glorified project manager.

Instead, I believe it’s incredibly valuable for founders to develop a strong understanding of product management before they make their first hire. Not only will this help you tackle the most critical product tasks yourself, but it will also make you better equipped to hire and appreciate a great product manager when the time is right.

This is a longer post, but I tried keep each section as brief as possible with key insights and valuable resources.

How will this information help?

Even without a PM on staff, understanding the role will:

  1. Help you manage product tasks effectively.
  2. Prepare you to identify when hiring a PM is necessary. Later in the article I also provide Marty Cagan’s advice on when to hire your first product manager.
  3. Equip you with the knowledge to evaluate and support a future PM.

What Founders Really Need to Know About Product Management

Product Manager Job Description

A Product Manager is the central figure responsible for defining a product’s vision, strategy, and roadmap. They ensure that the product meets customer needs, aligns with business goals, and is delivered efficiently by working cross-functionally with teams such as engineering, design, and marketing.

While PMs are often called the “CEO of the product,” this title is more metaphorical than literal — they are leaders without direct authority and rely on influence, collaboration, and clear communication.

Success Metrics for a Product Manager:

  • Achievement of business goals (e.g., revenue, growth, retention).
  • Positive customer feedback and satisfaction.

Essential Product Management Skills

Great PMs are strategic thinkers, skilled communicators, and empathetic problem solvers. They thrive in ambiguity, make data-informed decisions, and balance short-term wins with long-term vision.

The overview of skills below are inspired by The Product Map, a PM handbook developed by Graphica, a product design partner for startups. They have collaborated with global community experts to create a comprehensive knowledge map of product management topics and learning resources. It’s a true masterclass.

The role spans five key domains: Product, Customer, Analytics, Process, and People.

The Five Skill Groups

Mastery of these areas ensures that a founder, and eventually their product management team, can effectively navigate the complexity of developing, delivering, and optimizing successful products.

1. Product

  • Strategic Impact: Drive long-term success by aligning product initiatives with overarching business goals.
  • Product Discovery: Continuously identify opportunities by researching user needs and market trends.
  • Business Goals Ownership: Own key metrics and ensure product decisions drive measurable outcomes.

2. Customer

These skills collectively enable a founder or product manager to be a strategic leader, a customer advocate, a data-driven decision-maker, a process optimizer, and a team-builder.

Top 5 Skills:

  1. Analytical Thinking: Ability to interpret data and make informed decisions.
  2. Customer Empathy: Deep understanding of user pain points and needs.
  3. Strategic Planning: Define the direction and evolution of the product to maximize user engagement, growth and revenue.

When should you hire a product manager?

On a recent episode of Lenny’s Podcast, Marty Cagan of Silicon Valley Product Group had some great advice on this.

He recommends that founders should avoid hiring a product manager too early, as it can create unnecessary conflict and slow progress. In the early stages, especially before product-market fit, the founder should own responsibility for product value and viability. As the person closest to the vision and the customer, the founder is best positioned to guide product decisions. Hiring a product manager too soon often leads to “too many cooks in the kitchen,” making it harder to move quickly and align on priorities.

The right time to hire a product manager is typically after achieving product-market fit or when the engineering team reaches 20–25 people. At that stage, the company’s scale and complexity make it valuable to bring in someone to manage priorities and streamline the product process. A skilled product manager can then free the founder to focus on growth and new opportunities, while ensuring the product vision is executed effectively.
