Many founders mistakenly believe achieving product-market fit is the final step to explosive growth. However, growth only ignites after also finding a repeatable go-to-market fit, which translates the founder's initial sales success into a scalable process that a sales team can execute consistently.

Many founders mistakenly define Product-Market Fit by revenue (e.g., "$1M ARR"). The correct measure is the ability to predictably create customer value. This is best quantified by a leading indicator for long-term retention, not sales figures, as revenue can be achieved without true market fit.
Founders must consider their sales motion (e.g., PLG vs. enterprise sales-led) when designing the product. A product built for one motion won't sell effectively in another, potentially forcing a costly redesign. This concept extends "product-market fit" to "product-market-sales fit."
Committing all resources to a single demand trigger is a post-product-market fit move. Early on, founders need a broader approach to discover the repeatable patterns of demand. Only after identifying this pattern from early customers can you confidently build a concentrated "tollbooth" around it.
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.
Founders often create complex plans and documents to avoid the simple, hard, and uncomfortable task of selling. Just as getting stronger requires consistently lifting heavier weights, finding product-market fit requires consistently doing the core work of talking to customers and trying to sell.
Founders can secure meetings, pivot in conversations, and leverage their deep product knowledge in ways that hired salespeople cannot. This initial success is a unique, non-repeatable phase of founder-led selling, not a scalable go-to-market strategy to be replicated by a sales team.
You've achieved product-market fit when the market pulls you forward, characterized by growth driven entirely by organic referrals. If your customers are so passionate that they do the selling for you, you've moved beyond just a good idea.
Technical founders often create a perfect solution to a real problem but still fail. That's because problem-solution fit is useless without product-market fit. An elegant solution that isn't plugged into the market—with the right GTM, pricing, and messaging—solves nothing in practice. It's unheard and unseen.
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.
Successful founders can easily land initial customers and renewals through their personal network. This creates a dangerous false positive for product-market fit, masking whether the product has scalable value and can be sold by others without the founder's presence in the room.
