Strategic Must-Work Product Bet

Strategic must-work product bet is the product-management distinction Chris Best draws in Founder Mode: Chris Best, Founder & CEO, Substack. Some features are experiments to test whether they work; other products are so central to the company’s thesis that the team decides they must work and applies itself over years to make them real.

The source’s main case is Substack Notes. Best says Notes looked weak for roughly two years and was used by only a small set of highly engaged users, but Substack kept investing because owned discovery was necessary if Substack was to become a media network rather than only a publishing and payment tool. That makes the concept a more product-specific branch of Founder Mode.

The risk is that “must work” can become excuse-making if the strategic premise is wrong. In this source, the justification comes from Platform Dependency Risk: if writers depend on Twitter / X, Facebook, LinkedIn, or other outside networks for discovery, then Substack’s larger Creator-Owned Audience thesis remains exposed.

Key Claims

• Teams should distinguish validation experiments from strategically necessary products.
• A founder may protect a necessary product from premature shutdown when short-term metrics are weak.
• The strategic necessity needs a clear causal argument, not only founder preference.
• Must-work bets are especially plausible when an external dependency threatens the core business model.
• The approach still needs iteration, product taste, and willingness to make the experience enjoyable enough for ordinary users.
