For many SaaS founders, leading product development is intrinsic to their journey. However, a crucial question arises as companies scale: how long should a CEO continue to serve as the Head of Product? The consensus suggests this dual role becomes unsustainable when it demands more than 10 hours per week, or typically when a B2B SaaS company reaches approximately $3 million to $5 million in Annual Recurring Revenue (ARR).

At this stage, many B2B companies, even those exceeding $8 million to $10 million ARR, still lack a dedicated Vice President of Product. Too often, CEOs continue to "wing it" for far too long, hindering their company's potential. This practice frequently leads to three common mistakes among B2B founders:

1. Delaying the Hire of a Dedicated Head of Product

Founders often wait too long to bring in a full-time Head of Product, even as their product's complexity skyrockets. Once a product encompasses 50-100 workflows, dozens of use cases, and serves hundreds or thousands of customers—especially 15-20+ large clients using the product in diverse ways—it becomes too intricate for informal management. A general rule of thumb indicates that between $3 million and $5 million ARR in B2B, products typically become too complex for a CEO to effectively "hack" product strategy alone.

Hiring a true Head of Product ensures better-prioritized features, happier customers, and more effective trade-offs. CEOs who cling to the product role for too long risk shipping features and products that are no longer strategically force-ranked. The key is to hire a genuine head of product—someone who can take full ownership and has a proven track record of product leadership, not merely a project manager.

2. Reluctance to Relinquish Product Vision Ownership

While a CEO should ideally remain the strategic visionary for the company, the product itself eventually becomes so deep and rich, and markets evolve so rapidly, that the founders' original product vision can become simplistic, dated, or stale. Every five to six years, market dynamics shift significantly, and products evolve far beyond their initial "Day 0" vision. At this point, founders must empower their team to own the product vision.

Founders remain the heart of corporate strategy, but the product team, spending exponentially more time with customers, feature enhancements, and the nuances of product lines with thousands of features, is best positioned to define 95% of the product's future. The CEO's role then shifts from providing specific directions to setting the overarching strategic direction.

3. Hiring Underqualified Product Leaders

A common pitfall is hiring a product person who is too junior for the role. This rarely works. What's needed is a seasoned professional capable of owning the product and its roadmap—someone who has genuinely brought features into production and managed a team. This isn't a role for someone merely creating charts and hoping engineering will listen; it requires a leader with significant experience and authority.

In conclusion, it's advisable for CEOs to bring in specialized product leadership and delegate this responsibility a bit earlier than initially planned. While the company's initial idea and vision belong to the founder, both must evolve significantly over time to ensure sustained growth and innovation.
