Founders should abandon the idea of 'finding' product-market fit as a one-time event. Treat it as a state of constant refinement. The moment you believe you've achieved it, you start 'resting on your laurels,' which is the most dangerous place for a startup to be.

The founder of Briq rejects the idea of ever "achieving" product-market fit. He views it as a continuous process, like staying in shape. You must work on it every day. Believing you've permanently "arrived" is a sign of complacency that will lead to failure.

Product-market fit is no longer a stable milestone but a moving target that must be re-validated quarterly. Rapid advances in underlying AI models and swift changes in user expectations mean companies are on a constant treadmill to reinvent their value proposition or risk becoming obsolete.

PMF isn't a one-time achievement. Market shifts, like new technology or major events, can render your existing model obsolete. Successful companies must be willing to disrupt themselves and find new PMF to stay relevant.

The idea that startups find product-market fit and then simply scale is a myth. Great companies like Microsoft and Google continuously evolve and reinvent themselves. Lasting success requires ongoing adaptation, not resting on an initial achievement.

Unlike traditional software where PMF is a stable milestone, in the rapidly evolving AI space, it's a "treadmill." Customer expectations and technological capabilities shift weekly, forcing even nine-figure revenue companies to constantly re-validate and recapture their market fit to survive.

Doppel's founder argues PMF must be re-established with every pivot, platform expansion, or new market entry. For modern SaaS companies building platforms, founders must earn PMF for each new product they ship, treating it as a constant, iterative process.

PMF isn't a fixed state achieved once. It's a continuous process that must be re-evaluated at every stage of growth—from $1M to $1B. A company might have PMF for one scale but not for the next, requiring a constant evolution of strategy and product.

The market is evolving so rapidly, largely due to AI's influence on buyer behavior and competitive landscapes, that companies can't rely on a static product-market fit. It's now a continuous process of re-evaluation and adaptation every few months.
